Build It ‘Extensions Ideas for Adding Value’ article

Build It magazine invited Darren to share his expert advice on how to add value to your property by introducing an extension. The full article looks at how with the right design, a well-designed extension can significantly enhance a property, adding value and improving functionality.

Holly Cottage is featured as one of the showcase projects within the editorial, highlighting how including future proofing into a design can add long term benefits in terms of value.

 

Here we share the ‘Expert Q&A‘ with Darren, to read the full article the magazine is available to buy now.

How can a homeowner determine which type of extension might add the most value to their property?

It is impossible to give a ‘one size fits all’ answer for this question, as each property is different and owners requirements vary so much. When we are working on projects we look at a mix of factors, including the existing property layout, the loft space, external space and the potential for extending, to design a cost-effective solution which will add value in terms of the owner’s lifestyle needs and the monetary value of the property.

The most cost-effective way to extend your home is by altering what is already built, for example converting the space your loft tends to be cheaper than adding an extension in terms of cost per sqm, and reconfiguring an existing layout can often unlock the space you need without having to extend and lose precious outdoor space, example Cedarwood project.

How can clients balance functionality with value-adding potential?

This depends on the purpose for the changes. If you are wanting to make changes to a property to live in long term, then we would suggest that it is better to focus on adapting the house to improve your specific lifestyle requirements, creating a more positive living space to enjoy being in, rather than just focusing on adding value.

However, if you are thinking of making changes in order to sell in the near future, then we would recommend shifting the focus to look at adaptations which will have the most impact on the property value. The key areas to look at in terms of resell tend to include, creating a spacious kitchen with space to entertain in, adding an additional bedroom and completing a thermal upgrade by looking at glazing and insulation levels to create a home with a lower running cost.

 

Can the quality of design and materials affect the value?

Good quality materials, fixtures and fittings can have a considerable positive impact on the long-term value of a property, as these should last longer, reducing the need for frequent repairs and maintenance, and will ensure the look and the functionality is maintained.

Are there any ‘hidden’ value boosters homeowners should consider?

Increasing natural daylight into a property can have a hugely positive impact to the feel of a space, and also reduces the constant need for artificial light and heating. It is possible to increase the opening sizes of existing windows to totally transform a room, creating a contemporary feel with higher levels of daylight, matched with improved thermal properties. If physically extending it is worth considering the placement of new glazing, skylights are a great way to draw light into a home throughout the seasons, example Holly Cottage contemporary extension.

We also recommend that the existing layout of a property is interrogated, with clever design it can be possible to maximise the potential of the internal space available, to create the space owners need without having to physically extend.

Contemporary extensions within a conservation area

Homebuilding & Renovating Magazine asked Darren to share his expert opinion to answer a key question they had been asked by many of their readers; can you have a contemporary extension to my house within a conservation area? You can find the article appeared in the December edition of the magazine, or read it here.

Generally speaking, yes you can. Having a home located in a conservation area does not mean you have to be stuck in the past with the architecture of any additions to the scheme but you do have to be mindful of the design, with what you are trying to achieve and your material choices.

Each conservation area is different, and it is always worth working with an architectural practice who have a proven track record in your specific conservation area. When we recently extended and sustainably upgraded an existing home (Cedarwood) which was set within a conservation area within the South Downs National Park, we were able extend the ground floor and add a striking, contemporary loft extension to the original Colt timber framed house.

We found that working in collaboration with a planning consultant and the local planning department meant we were able to have an open and constructive dialogue from the start of the design process, on this project we found the planning officers were keen for the extension to have a distinctly different architectural language from the original. A key concern for this property was the potential overlooking issues  with the loft extension, our solution was to set the dormers at an unusual angle, creating a striking design which successfully has minimised the concerns.

When looking to extend your project within a conservation area we would suggest looking at commissioning a heritage statement / document, that addresses the scheme and working closely with the conservation officer from the onset, and working with an architect with a track record of working within your specific conservation area.

If you have any further questions or have a project you would like to discuss, do get in touch with the team today.

Listed building planning success

We are delighted to announce we have secured planning permission to sympathetically refurbish and extend a Grade II listed Regency villa in central Southampton.

The design will extensively renovate the existing building, to deliver a scheme that enhances the rich, historic personality of the original dwelling and upgrade the energy efficiency of the property. A contemporary extension, replacing the current, poorly constructed extension, will create a largely glazed structure to transform the rear of the property with a spacious kitchen running across the whole elevation of the home. The work will breathe new life into the property, to create a functional, joyful home for the owners and their young family.

You can read more details about the project here; we have also written an article about working on listed and heritage building which you might find interesting which you can find here.

Working on Listed and Heritage Buildings

In the UK we are fortunate to be surrounded by beautiful architectural buildings across multiple generations, in many towns and villages you can find a rich tapestry of architectural gems showcasing our living history. If you are lucky enough to own a heritage property then you might need to think a little more carefully before you undertake any renovations, extensions or alterations as you will probably need to get these approved in advance.

At Studio BAD we have in-depth experience working on listed and historic buildings, we have been fortunate to work on several interesting project schemes such as adding a contemporary extension to Holly Cottage, reimagining a Georgian townhouse in Southampton and reinstating a historic dwelling in rural Hampshire.

Through the design process we get asked many questions about working with listed buildings, so we thought we should share some of these with you. Please note that no two projects are the same, what is acceptable to one listed building is not necessarily acceptable for another and these notes are only intended as a guide.

It’s my house, why can’t I do what I want to?

Buildings are listed as they hold special architectural or historic interest, if you are lucky enough to own one of these properties you have an additional level of responsibility to preserve the building. This does not mean you cannot alter the property; you just need to have some additional permissions in place before you do to ensure the historic integrity of the building is kept intact.

How do I know if my property is listed?

If you are not sure about the official status of your home you can easily check using the Historic England database, which you can find here.

When was a building listed?

The full details of a property listing are available on the Historic England site, including the date it was first listed and other information including the grade of listing, reasons for designation and a short history of the entry.

What makes a listed building?

There are three main principles when it comes to getting a building Listed: The age and rarity of the structure, the architectural or historic interest and any historical associations.

There are three main grades of listing in England:

  • Grade I – buildings of exceptional interest (around 2% of listed buildings)
  • Grade II* – buildings of particular importance and of more than special interest (around 4% of listed buildings)
  • Grade II – buildings of special interest, which represent an important part or our built heritage (around 95% of listed buildings)

It is worth remembering that grading can be changed where reevaluation takes place after damage or alterations, as more evidence of a building’s history or architectural quality is uncovered.

Can a building be delisted?

It is very rare to have the listing of a building removed, however it is occasionally possible. Historic England will consider a review of a property listing provided it is accompanied by new evidence relating to the architectural or historic interest of the building. Please note that evidence about the building’s condition, cost of maintaining it or redevelopment plans, cannot be taken into consideration for delisting.

Can I extend my listed building?

Yes of course, having a listed building does not mean that it has a preservation order on it preventing any change, it just means that any change has to be carefully considered so it does not affect the special interest of the property.

Can I have a contemporary extension on a listed building

Yes! Having a heritage building does not mean you have to be stuck in the past with the architecture of any additions to the scheme. Often conservation officers will be keen for any extension to have a different architectural language from the original, to allow the history of the building to be easily read.

See our Holly Cottage project, where we successfully added a contemporary ground floor extension to create a modern kitchen and separate family room onto the listed property.

Can I demolish a listed building?

Sometimes this is possible, but you would need to have Listed Building Consent and Planning Permission in place before you were to do this. The conservation office assigned to you would make a decision on a case by case basis, taking into account the condition of the building, its function and other issues.

Is Listed Building Consent the same as Planning Permission?

No, these are separate permissions. Depending on the work you are looking to undertake it will determine if you need one or both in place before you start any work. The best place to start is either by speaking with your local authority Conservation Officer, or if you are working with a professional Architectural practice, they should be able to help advise you about what is needed for your specific project.

Listed Building Consent is the legal permission you need to have in place to alter your listed building, it is worth remembering that it is a criminal offense to alter your building without this in place first. The case officer will help to oversee the project and ensure that any alterations are in keeping with the original character of the building.

Planning Permission is needed for the majority of work done to the exterior of any property (some alterations fall under Permitted Development, but it is best to check with your Local Authority before you start) so this might also need to be in place if, for example, you were looking build a kitchen extension onto your Listed home.

Do I need planning permission when working on a Listed Building

Not always, planning permission is only needed for making alterations to the exterior of your home. You will not need planning permission for regular maintenance, or to change items such as the internal staircase or the fireplace, but you might still need to get Listed Building Consent for both of these examples.

How do I get permission for altering a Listed Building

When working with a Listed Building it is always best to engage with an experienced architect who has previously worked on Listed Buildings, with a proven track record in securing planning for similar projects to your own.

Once you know what alterations you are looking to do it is best to apply for Planning Permission and Listed Building Consent at the same time. For both of these you will need to prepare detailing drawings and documents that show the current state and the proposed changes.

Are listed buildings exempt from Energy Performance Certification (EPC)

Most properties need an EPC when you build, sell or rent them, but there are a few exceptions when this certification is not needed including if the property is listed, you can find more information here.

What is the Local Heritage Asset Register? (The Local List)

The Local Heritage Asset Register is a register of local heritage assets that may not quite meet the strict requirements for national listing, but that still make a significant contribution to the historic environment of their specific locality or district. To make any alternations to a locally listed property you might find there are some restrictions in place that you need to adhere to, an experienced architect or your local planning department will be able to help you understand what these might be.

Can listed building consent be granted retrospectively

In short, yes it can be but it is always strongly recommended to get your permissions in place before you start any work, as it is a criminal offence to undertake unauthorised work to a listed building.

What is listed building curtilage

Curtilage listed, or listed by association, is a term used to describe buildings with the grounds (or curtilage) of a listed property which is also subjected to the listed building itself and will need to apply for listed building consent before any work is undertaken. These structures can often include boundary walls, outbuildings, farm buildings, coach houses or workers cottages which are located in the grounds of the principal listed building or was ancillary to the principal listed building at the time of listing.

We hope those FAQ’s have helped you get a better understanding of how to work on a listed building, as restrictions and regulations are always changing, we would recommend you speak to an architect (especially us!) or your local planners before starting any work.  From our experience working on a listed property does not rule out interesting architecture, it just means you have to be more mindful in what you are trying to achieve, your material choices and materials used, often resulting in a more interesting design solution.
