Derbyshire Life – Constructive Conservation

PDP_Constructive Conservation

Chartered Town Planning Consultant Jon Millhouse of Derby-based Planning & Design Practice Ltd, discusses three recent projects at Holbrook, Breadsall and Ambergate, aimed at revitalising historic Derbyshire places in Constructive Conservation written for Derbyshire Life.

Hidden amongst our towns and villages are historic buildings of all kinds. They are important to our sense of history; part of the fabric of our communities. Sometimes, these buildings are no longer required for their original use. They become vacant and run down, and the money needed to restore them cannot be found. Finding a viable use is often key to securing the restoration and long term maintenance of our historic buildings. This is not always easy, however. There are practical and bureaucratic challenges to overcome. Where new uses can be found and new investment stimulated, the outcome can be most rewarding.

Jon Millhouse and his colleagues at Planning and Design Practice have sought to combine planning know-how with creativity and sensitivity to older buildings, in order to devise proposals that would bring about the restoration of a number of historic buildings in the county.

One such proposal is the redevelopment of Highfield Farm at Holbrook. Planning & Design Practice obtained planning and Listed Building consent on behalf of the Trustees of the Strutt Estate, for the restoration and re-use of a 17th century farmhouse and barns, and the construction of a sympathetically designed new house in the grounds.

At Brookside Farm, Breadsall, a delightful old farmstead formerly owned by the Harpur Crewe Estate in the heart of the Breadsall Conservation Area, permission was granted for a re-use scheme involving the restoration of the farmhouse, renovation and conversion of two barns and construction of two new homes alongside.

At the former Ambergate Social Club, which was originally an 18th century farm owned by the Hurt Estate, consent was obtained for the restoration and re-use of an old farmhouse and barn, and the construction of new homes on the site of the derelict social club and car park.

Jon explains the process: ‘The starting point, and my favourite part of the job, is to look at a site, identify all the constraints and opportunities, and come up with an idea – a concept for unlocking the site’s potential.

At Holbrook for example, I was keen to include a new build home in the proposals if possible, to help raise the value of the site and potentially cross-fund the renovation of the older buildings.

I also wanted to include within the proposals the restoration of an outlying barn which on its own was too small for alternative uses, but with a small extension, would make a good holiday let. The next step is to discuss with the local Council how the proposal might fit with relevant planning policies. At Holbrook, we were able to secure the Council’s in-principle support for the extension of the outlying barn (despite the barn itself being situated just inside the Green Belt) by siting the new build element inside the farmhouse garden, and their support for the new house by siting it in a discreet location in place of an ugly modern farm building.

At Ambergate, we discussed with the Council the principle of changing the use of the site from a disused social club to residential accommodation, and the concept of building a short terrace of houses, which we felt was appropriate for the Derwent Valley. The terrace would address the A6 when entering or exiting the village whilst still maintaining views of the old farmstead beyond.

At Breadsall, despite the site being in the heart of the village where new build accommodation is potentially acceptable in principle, we wanted to take a sensitive approach, working with and re-using the existing buildings and carefully inserting some new development alongside, rather than wholesale redevelopment. The old farm had so much character that it deserved a sensitive approach.

I remember a Councillor describing the farm, when the application eventually came before the Planning Committee, as “a little piece of paradise”.

After initial feedback has been received from the Council, we would typically consult other interested groups – Parish Councils, the highway authority as well as carrying out various technical surveys

Once all of this information has been collected, the detailed designs can be begun in earnest’.

Working with historic sites can often reveal interesting nuggets of local history.

Jon explains: ‘At Ambergate, after checking old maps it quickly became apparent that we were dealing with an old farm of considerable age, despite most people who know the site probably only thinking of it as a social club. We then spotted some initials on a date stone, suggesting a connection with the Hurt family – industrialists and major landowners 150 years ago.

‘At Holbrook, we commissioned an archaeological report which uncovered an old floorplan drawing of the barns prepared for the Strutts before they upgraded the farm. It showed how the family were trying to create a type of “model farm”. Some, but not all of their vision was carried out.

‘You then start to appreciate how the history of these individual places links with the history of the wider area. The Strutts were presumably trying to apply their industrial knowhow to farming, in order to feed their mill workers at Belper. Jedediah Strutt was also from a farming family, even inheriting a farm at Blackwell from one of his uncles before he set up his mills.

‘Historic properties such as these can provide a little window into our past. We hope that by facilitating the re-use of such sites, their heritage interest can be better revealed and maintained over the longer term.

‘Constructing new buildings in Conservation Areas, or next to Listed Buildings, is not always universally popular. There are some who would prefer to see such places left untouched. I agree that a balance must be struck, and there are places where new development wouldn’t be appropriate. However, historic buildings can quickly deteriorate if left derelict. Finding a viable use is key to securing long term upkeep. There are many instances where the right type of development can make a positive contribution to the conservation of our heritage.’

The Housing Delivery Test

PDP_Housing Delivery Test

The results of the Housing Delivery Test were published in February. Local Planning Authorities sent figures to the Government for the last 3 years setting out the number of homes completed in their areas against their housing targets.

The majority of Councils in the Midlands met the target. However, seven failed. These were Derbyshire Dales (93%), Tamworth (86%), Melton (84%), Chesterfield (66%), Erewash (66%), Staffordshire Moorlands (64%) and Sandwell (61%).

Councils with between 85% and 99% delivery have to produce an Action Plan that sets out the measures the Council will take to boost the delivery of homes in their areas. This could include extra funding for affordable housing to increase the speed of delivery and incentivise builders; it could also include support for smaller builders using the government’s House Building Fund.

For Councils delivering between 25% and 85%; these councils must increase their housing target by 20%. This means allocating or granting planning permission for new housing sites; so, if a council must delivery 300 homes a year, the target is increased to 360 homes a year.

The housing delivery test measures housing completions. A completed house is a property with a Building Regulations Completion Certificate or a property that is ready for occupation today. Evidence has emerged from at least 1 council in Derbyshire that this strict definition is not being followed. The Council is assessing completions as homes which have a roof, walls and windows, weathertight but not completed. This inflates figures and includes properties to first fix, those held by builders, until a buyer has been found. These properties may not be ready for occupation for perhaps 3 or 6 months and should not be counted as completed. If this approach is being adopted more widely then the completion figures have been inflated, allowing councils to avoid providing more housing land, potentially limiting development and reducing the supply of housing to local communities.

The Housing Delivery Test is a difficult concept for Councils because they are not usually house builders; but the test exposes poor delivery by all parties in the house building industry and the Housing Delivery Test could become as important to the construction industry as the 5-year housing land supply.

Do you know about the Party Wall Act 1996?

Most people are either unaware of the Party Wall Act, or unclear of the details. The Party Wall Act covers the protection of neighbours from work that may affect their property. There are a few examples of what a Party Wall actually is: a party wall can be a shared wall in a semi-detached property or a garden wall on a boundary line. The most common time a Party Wall Agreement is required is when an extension or new dwelling is proposed close to a neighbouring boundary.

The Party Wall Act itself is a very powerful piece of legislation that protects homeowners from any kind of negative impact on their property in the case where a neighbour carries out construction works. This most often occurs when a construction operation impacts the integrity of foundations of existing property, that property may then experience settlement or subsidence due to the new loading and effects of new elements.

This impact is exactly what the Act tries to limit, avoid completely or at least assign legal protection in the case in which something happens in the future.

If you are intending to do any traditional building work within 3 metres of the boundary with a neighbour it is your responsibility to agree terms with that neighbour. This should be done at the earliest opportunity so that you can avoid any unnecessary legal issues. If you do not approach your neighbour, they are entitled to come to you to address the situation and at that point they may involve Party Wall Specialised Legal teams and these can be chargeable to you directly, not the neighbour!

Permission secured for a new dwelling incorporating historic farmhouse ruins

Planning & Design have secured planning permission for a new dwelling which incorporates the remains of a historic farmhouse. The ruin is located in Blackbrook, Belper, within the Derwent Valley Mills World Heritage Site Buffer Zone.

The Holly House Farm ruin is famous for its association with the Slater family. Samuel Slater is known as the ‘Father of the American Industrial Revolution’ after he took the British textile technology to America and made his fortune. It is believed his family owned the farmhouse in the 18th century. It is known that his descendants returned to Blackbrook and built Holly House, which sits to the North.

There were a number of planning and design issues to overcome with this project. We initially approached the Council with an application to reinstate the farmhouse by rebuilding it as it once was. However, in order to support the application, the Council stated that this should be a new dwelling, much more contemporary in form, so the dwelling would read as a new phase of life for the ruin.

The design had to work with the ruin and so any design would be truly unique. Remains of Holly House Farm still survive, and there are likely still remains of the associated outbuildings beneath the topsoil. The above ground remains include rubble stone walls of the historic farmhouse, including part of a gable end and steps leading down to the basement. The basement itself is still in remarkably good condition.

The ruins will be retained and a new structure will be inserted into the remains. The concept of reusing the existing stone walls retains the history of the site. A new structure inserted inside adds a layer of evolution and displays a building of the 21st Century.

The new dwelling will follow a courtyard arrangement similar to the layout of the original buildings, which formed Holly House Farm. The forms are traditional (akin to barn structures), however a contemporary element has been added to the gables, with glazing to the apex in the dining areas of the main dwelling and annex.

The proposed materials are timber vertical boarding to blend in with its surrounding woodland setting. The vertical timber boarding will act as a contrast to the old stone, whilst the glazed flat roof link will provide separation to the forms and allow for views through the site into the woodland.

The proposal was not in compliance with the adopted Local Plan, however because Amber Valley do not have a five your supply of housing land at present, the application was considered in the context of the presumption in favour of sustainable development, as stipulated by the National Planning Policy Framework. The Conservation Officer did not object, and as such it was considered that there would be no harm to the setting of the Derwent Valley Mills World Heritage Site. Two other new dwellings had recently been granted on Longwalls Lane, which established the safety of the access off Ashbourne Road, which had previously been questioned.

The development was referred to Planning Board by a local councillor, and was subsequently approved by the Committee, with one councillor remarking on the high-quality design of the scheme.

PDP secure planning consent for barn conversion in Amber Valley

PDP_Barn Conversion

Planning & Design Practice recently secured planning permission for a barn conversion within the Amber Valley Borough. The barn was starting to become weaker, with one wall on the rear elevation beginning to crumble and a steel bracing holding the two main walls firmly in an upright position.

We were approached by the client to prepare designs for the conversion of the building to create an aspirational dwelling in this highly sought-after location.

After a number of sketch scheme ideas, we decided on a design to maximise the space and comfortability of the building. The barn will be converted into a 2-bedroom dwelling including one with an ensuite. We also decided that the dilapidated timber extension could be demolished and re-built on the same footprint to add a contemporary touch to the barn, whilst retaining an agricultural feel.

The application achieved planning consent with minimal complications. Approval was granted in November 2018.

New Dwelling Granted in Kirk Langley Conservation Area

PDP_Kirk Langley Conservation

Planning & Design Practice have secured planning permission for the replacement of an existing barn with a new dwelling in the Kirk Langley conservation area.

Kirk Langley is a village a few miles northwest of Derby. Back in 2017 a scheme was approved to replace a steel framed barn with a high-quality, contemporary new dwelling on the exact same footprint. The client then sought to make some changes to the approved scheme, the most significant of which was the addition of a basement level to the building.

The impact of the development on heritage assets was a key consideration as the site is located in a conservation area and in close proximity to a listed building. The council agreed that the high quality design of the building meant that it would not materially harm the significance of these heritage assets.

We look forward to seeing the building take shape in due course.

Frequently Asked Question – “But I have Planning Permission, why do I need Building Regulations approval as well?”

PDP_Planning Permission Building Regulations

This is one of the most common questions I come across when working with clients on domestic projects. Most people that don’t work in the construction industry will be completely unaware of the full process that precedes construction on a project. Planning permission and Building Regulations, although related to the construction of an idea into a building, are both two independent monitoring bodies. I will explain the difference and the need for both.

From the formation of an idea for a construction project to actually breaking ground is actually quite a lengthy process. There are many boxes that need to be ticked and a great deal of planning and design work to get through. Designing a house or even a small extension to a house comes with a lot more detailed design input than simply deciding the shape and size of the element to be built. Truly good design considers the impact of what you are building on the environment around it.

Local Planning Authorities are concerned with exactly what a project looks like and how it will impact everything around it, from the street scene to the direct neighbouring properties. Once you have achieved planning permission, you then need to abide by the Building Regulations too.

Building Regulations are a group of documents that have been created with the Health and Safety of occupants in mind, both inside and outside of the build itself. Once you have Planning permission, we then deal with a separate government body that deals exclusively with Building Regulations. Drawings are then used to provide all of the necessary detail to comply with Building Regulations.

Building Regulations will ensure that the design of the proposed building is suitably constructed so that it performs to current standards. This incorporates everything from structural integrity, fire safety, through to lighting, conservation of energy and even being thermally efficient.

These standards cover every detail of the build from having the correct foundations for the site conditions, through to the right insulation to keep the building sufficiently warm. The Building Regulations are probably the most important element of the whole construction process; making sure that the build is safe, and will provide a suitable environment for all that will use it, ensuring it will be fit for purpose and future proofed as much as possible.

The process of planning and designing a project is an art that we pride ourselves in undertaking. We take pride in being a practice that is able to take you from an initial concept, design it, navigate the difficult planning process, through to the building regulations and the construction site and finally completion of the project, , saving time and money through well-thought-out design.

PDP Secure Permission for New Sheep Dairy Enterprise at Historic Derbyshire Farm

PDP_Wakebridge Farm

We were delighted to obtain planning and Listed Building consent in December for the redevelopment of Wakebridge Farm, Crich, to form a sheep dairy enterprise with an associated creamery, hotel, restaurant and bar.

Wakebridge Farm is a former dairy farm including a Grade II Listed late 18th Century farmhouse and attached stone barns (all in need of restoration and repair), built by Peter Nightingale on the site of a medieval manor house and chapel. The farm sits in a small valley overlooking the Derwent Valley, within the World Heritage Site Buffer Zone. On the adjacent hillside is the Grade II* Listed Crich Stand, as well as the Crich Tramway Village, a popular tourist attraction.

Our clients, who have many years’ experience in farming and veterinary practice, wish to develop on of the first sheep’s milk enterprises of its type in the country, with an on-site creamery to produce cheese and other dairy products, and viewing platforms to allow visitors to see the whole process in action.

The old farmhouse and barns will be sensitively converted into a small hotel and restaurant (selling produce from the farm), as well as a training room for veterinary and agriculture students.

This multi-faceted proposal, in a sensitive area the subject of many restrictions and designations, required careful navigation through the planning process. We took on board the views of various consultees and adjusted the plans where appropriate, culminating in what we hope will be an exciting but neighbourly development, contributing positively to the local economy and tourist offer.

We were very pleased when the Amber Valley Planning Board unanimously voted to approve the application at their December meeting.

Government considering key changes to the General Permitted Development Order

PDPGeneral Permitted Development Order

The Government published a consultation which ran from 29th October 2018 until 14th January 2019 titled “Planning Reform – Supporting the high street and increasing the delivery of new homes.”

The most significant proposal is to introduce new Permitted Development (PD) rights “to provide additional self-contained homes by extending certain premises upwards”. It is proposed that the new rights would apply to premises in a range of uses that are compatible with C3 residential use. These are defined as potentially including:

“C3 residential premises, those A class and sui generis high street uses that can already change use to housing under a permitted development right ((shops (A1), financial and professional services (A2), restaurants and cafes (A3), betting shops, pay day loan shops and launderettes), offices (B1 (a)), and buildings in mixed use within these uses.”

It is proposed that the PD rights would not apply to: Article 2(3) land (including conservation areas, areas of outstanding natural beauty, the Broads, National Parks and World Heritage Sites), Sites of Special Scientific Interest (SSSI), the standard 4 exclusions (i.e. listed building, scheduled monument, safety hazard area, or military explosives storage area) or safeguarded land within 3km of the perimeter of an aerodrome.

The Government is proposing two different ways to deal with the height restrictions. Either, a PD right could allow premises in a terrace (of two or more properties) to extend upwards to be no higher than the main roofline of the highest building in the existing terrace, or, upward extensions could be permitted more widely to a height no higher than the prevailing roof height in the locality.

There is additionally a proposed maximum limit of no more than 5 storeys above grand level once extended (based on an additional storey not exceeding 3m in height). However it is proposed that this height limit would not apply in the case of purpose built, free standing blocks of flats over 5 storeys, which would be allowed to extend upwards (i.e. to a height greater than 5 storeys above ground level).

The applicant would still be required to apply to the Local Planning Authority for approval on a number of issues, such as flood risk and impact on neighbouring amenity.

The document also asks the question of whether these PD rights should additionally allow the upward extension of a dwelling for the enlargement of an existing home.

The second significant proposed change is to allow the demolition of commercial buildings and redevelopment as residential. At present, PD rights allow new homes to be delivered through change of use of existing buildings. The Government suggest that allowing demolition of commercial buildings and replacement build as residential, would allow high quality development to be secured which is consistent with national planning policy.

Feasibility really needs to be explored before this becomes a PD right and factors such as the height and density of new buildings would also need to be considered. It is also being considered whether the right should just apply to smaller sites, as this would be more practical. However it would still have the benefit of setting a precedent for larger sites.

Other matters being considered are:

-To allow shops (A1), financial and professional services (A2), hot food takeaways (A5), betting shops, pay day loan shop and launderettes to change to office use (B1). It is also proposed to allow hot food takeaways (A5) to change to residential use (C3);

-The removal of the existing right that allows the installation of, and advertising on, new public call boxes;

-Increasing size limits for off-street electric vehicle charging points;

-Greater flexibility for temporary changes of use;

-Making permanent two currently time-limited PD rights (B8 to C3 & larger extensions to dwellinghouses)/

There have been some fierce critics of the proposed changes. The Town and Country Planning Association has warned that the proposed changes will deprive local authorities of essential funding and risks creating poor living conditions for vulnerable people.

Dr Hugh Ellis, interim chief executive of the TCPA, said:

“Converting commercial and disused high-street properties into homes is fine, so long as it doesn’t condemn desperate people — often young people or poor families — to live in badly designed boxes without consideration for their health and wellbeing.

“Under the existing system of permitted development, 1,000 new flats can be built in an old 1970s office building or industrial estate, and the local council can’t require a single sq. ft. of play space for the children who live there — and the communities have effectively no say. This cannot become the norm.

“The rebirth of town centres requires vision and masterplanning, with real investment in culture and the built environment. How can we pay for this investment when permitted development removes the power of local authorities to get one penny in section 106 contributions from developers?”

The responses to the consultation will now be considered before any proposed amendments are published. We will provide an update on this in due course.

PDP secures permission for conversion of historic buildings in Longford

PDP_Wolfenden Barns

Planning & Design have successfully obtained planning permission for the sensitive conversion of a listed Farmstead in Longford, Derbyshire Dales. The farmstead had been a dairy farm up until summer 2018, however the farm was no longer viable and the client wished to consider other practical uses for the listed barns. The client has already successfully converted another building on their land to a holiday let, which is frequently occupied.

The proposed scheme comprises six holiday lets – two in the Grade II brick Cowshed, one in a section of the Grade II* brick Hay Barn and a further three in a modern steel frame barn.

Careful consideration had to be given to the setting of the listed farmstead and the location of parking and given its proximity to public footpaths.

Design details had to be resolved at an early stage, which is common for Listed building applications, as Local Planning Authority Conservation officers are required to approve the details. We ensured that the open feel of the barn was retained by having open plan living/kitchen areas, retaining and replacing the rooflights to the internal roof pitches and keeping the roof trusses exposed.

Changing the use of the barns to holiday lets means that the barns will remain in the same ownership and control as the rest of the listed farmstead. Whilst this is not a mandatory item for planning, it is an aspect that is considered more favourably in planning and listed building consent applications for conversion to dwellings.

As the project was so large, complex and detailed, we negotiated with Derbyshire Dales District Council to resolve planning and design issues before the project was recommended for approval at Planning Committee.

The Planning Committee spoke highly of the scheme and were pleased to see a new use for the redundant barns, commenting how they would like to be invited back to see the finished project. The committee unanimously approved the scheme in November 2018.
