Extending your home is a popular way to increase space and add value to your property. With the hassle and costs of moving house – from legal fees to stamp duty – the reasons to stay put and improve your existing home soon mount up.
But where do you start? We have compiled information about House Extensions to help you make an informed decision.
TYPES OF HOUSE EXTENSIONS
There are few world-class cities where you can own your own house and convert it for your needs, and none as exciting as London. The city’s rich stock of residential housing has great potential for improvement. If you already own property in the capital and can’t justify the costs of moving house, renovating and extending your existing property may be the right move for you. Best of all, you’ll be able to stay in the neighbourhood you know and love.
Strict planning regulations in neighbourhoods rich with heritage housing make house extensions a challenge for some. Seeking the help of an architect, rather than going directly to a standard-issue builder or home-extension specialist, means the specific character of your home will be respected and enhanced. An architect will unlock potential and use materials in an original way that can complement your home’s historic appeal.
Once you’ve found an architect whose style and personality balance your own, the process of transforming your home will fall into place. Together you can collaborate on tailoring the original bones to your personal lifestyle with detailed specifications, starting from the party walls inward. Even if planning regulations are stringent in your neighbourhood, you’ll usually be able to extend outwards at least enough for an extra room or two – taken from wasted outdoor space, eaves in a pitched roof or awkward corners you didn’t even know you had.
You could extend a kitchen to incorporate an eat-in breakfast room, add an en suite bathroom, a bedroom for a new child or a home office. In a neighbourhood with newer housing stock, like a London suburb or brownfield development, more involved home extensions may be possible, like wraparounds incorporating a side return and rear, a second storey, garage topper or double-height rear extension.
House extensions are carried out in a more compassionate way today than they’ve ever been, and a good architect will strive to preserve original architectural elements – like decorative cornicing, ceiling roses, skirting boards, dada rails and picture rails – while giving your home the modern openness so many desire. Pivoting doors and Crittall-style steel windows are brilliant complements to period decorations and antique brick.
Once you’ve committed to the process, a house extension will make additional changes easier and less cumbersome, like new sash windows, flooring or a fresh paint job. They could be done concurrently with the structural work, pull everything together and help you get a good-as-new home that works with your unique way of life.

YOUR HOUSE EXTENSION PROJECT
Scenario is a boutique architecture studio focused on improving homes with spacious, contemporary extension projects across London and beyond. Through our bespoke architecture service, we tackle projects of every scale and complexity, from modest single-storey extensions to side-return extensions project, basement extensions, loft extensions and rear house extensions project.
Our highly skilled architects can take you step-by-step through the challenge of building a house extension. We’ll collaborate closely with you from the initial drawings, detail design and planning, guiding you through the tender and construction process and completing your house extension on time and on budget.
Early adopters of the latest drafting and building technologies, we use innovative 3D design and visualisation tools as a standard for all our house extensions. Our experience has shown that real-time visualisations and virtual reality are extremely efficient tools for choosing finishes, fixtures and fittings, and simulating natural light.
We use 3D building information modelling (BIM) to produce reliable construction information, so all our project data comes from an accurate 3D model. Using this technology collaboratively with consultants and contractors is proven to save our clients time and money. This Chartered Institute of Building case study featuring a Scenario project demonstrates the benefits of this advanced technology for house-extension projects.

HOUSE EXTENSION COSTS
Nearly any property you purchase in the southeast will retain or accrue value. When and if it turns out you need more living space, you’ll want any enhancements you make to the size of your home to enhance your asset, too.
A good architect will factor in your home’s location, layout, structural integrity and the size of your family to make your project work for you and your budget. A house extension cost shouldn’t cancel out the benefits of a house extension.
Unless your investment is a purpose-built flat, you should be able to gain extra space that suits your lifestyle. If you own just part of a house, you can build up, down or out, depending on your specific location. If you own the entire house, chances are better you can add substantial square metres.
In some neighbourhoods around London, loft extensions and side-return extensions (recouping the side-rear void often left open between terraced houses) are grouped under “permitted development”, which means they sometimes don’t require planning permission from the local council if the final plans heed the extended volume requirements of the area. Avoiding time-consuming planning applications will save you money in the short run.
On the topic of money: it’s always difficult to propose a house extension cost without evaluating the home in question, the resident family and their plans. But it’s likely you can nearly double the size of your home’s original square-metre floor area at a fraction of the cost of the original house. Plus you will, of course, gain a nearly new living space without paying the stamp duty and agents’ fees associated with moving house – although you may need to purchase renovations insurance.
As with most building-related activity, it is wise to source three to five quotes for a house extension. With a range of budgets to hand, you’ll be able to assess which seem low, high and just about right, and choose accordingly. The foundation, walls and roof will soak up about 15% of your costs, followed by Velux and rear glazing.
You’ll want to price fixtures, fittings, appliances and any upgraded materials separately, so as not to be shocked when you receive that last bill – new kitchens are particularly dear, so keep your eyes out for deals and floor sales in the months leading up to a project. Once you’ve agreed on a budget, set up a payment plan with your architect and builders that works for everyone.
The House Extension Cost varies and this will depend on the scale, design, exterior materials and interior finishes of your extension. Before designing an initial concept for our clients, we discuss their big-picture aspirations and daily requirements.
When we budget the House Extension Cost on any home, we must consider the different types of extensions projects. Extending upward with a loft extension, for example, is often significantly cheaper than a side-return extension and rear house extension and most definitely a basement extension.
We understand our clients’ desire to understand the cost of building an extension before committing to the process. For a single-storey extension – be it a side-return extension or rear house extension – we allow between £2,500 and £3,000 per square metre, depending on finishes. These figures can also apply to renovating the existing areas within a house.
Excavating a new basement is a great way to add significant floor space to your house with limited planning regulations. However the House Extension Cost per square metre is, by far, the highest in a basement. We allow between £3,000 and £3,500 per square metre, subject to finishes.
- The decision period clock only starts ticking once the application is validated by the Council, This requires then to check that the forms are completed correctly and that the submission contains all the necessary drawings, statements and reports.
- Although required by law to provide a decision within the statutory eight weeks period, it is not uncommon for councils to miss the deadline of the consideration period, normally only by a few days, sometimes longer.
- In some cases the council may ask us as your agent for an extension of time, this may be requested due to internal reasons or as an acceptable result of a professional discussion that we are conducting with them about certain aspects of the application that they are not sure about.
- Our experience shows that planning officers respond better to projects when they feel consulted and collaborated with. We find that when we truly listen to their often helpful and valid feedback and treat them as consultants for the projects and not representative of an evil enforcing authority, they tend to collaborate well with us and demonstrate increased flexibility.
- Although the council in theory have eight weeks to consider your application, in practice they are constantly overloaded. They will only look at your application in the last few days of the consideration period. If this is the first time that they come across a scheme that they were never consulted about, our chance to secure permission for you in a single attempt is significantly compromised.
- The standard practice is for the council to consider the full planning application as submitted and then issue a yes or no decision. Case officers are not required or even encouraged to enter a discussion with us or accept resubmission of minor changes to the proposed scheme during the consideration period.
