Guide to side returns
This simple addition can maximise comfort and value. Read on to discover how adding a side extension could pay off
How to extend without losing garden space
Though it’s easy to discount a side return as simply wasted space at first glance, this small area can massively transform the way you live. Extending into the side return can make the difference to a renovation project by creating a better link to a garden, an openplan kitchen-diner, or add space to fit that cherished utility or downstairs WC.
This represents a big investment so getting it right is crucial, which means that you need to engage the right team from the initial design concept to the trades that will be working on it. Undertaking a side extension might allow you to live on site and, therefore, save money on renting for the duration of the project. Plus, you’ll also be on hand to answer any questions and help resolve issues that might come up.
The results will be worth it, but don’t just take our word for it – here are some successful examples of how you can realise the potential of the space and create functional new areas.
PERMITTED DEVELOPMENT
A side extension is considered permitted development as long as the new addition doesn’t extend beyond the rear wall of the original terraced house by more than three metres, or by four metres if the property is detached. It must be single storey (no more than four metres high) and must not exceed more than half the area of land around the original house (as it was first built or as it stood on 1 July, 1948, if it was built before that date). It must also be no wider than half the width of the original house. Properties that are listed or are in Conservation Areas require planning permission.
MAINTAINING BOUNDARIES
If you live in a terrace where you’ll need to build or excavate near the boundary, you will have to speak to neighbours about your plans before going ahead. If you can reach a verbal agreement, you can then ask them to sign a Party Wall Notice. This will save you money on professional fees. Otherwise, you will need to engage a surveyor or build away from the boundary. This must be done between two months and a year before you plan to start the work.
MAKE IT BRIGHT
Single-storey additions allow you to add rooflights, which can flood the space with illumination even on grey days when paired with a set of glazed rear doors. A few opening rooflights will make all the difference, while a row of fixed panes will give you the wow factor. Remember to consider practicalities such as how you will clean the glass, as well as making sure you’re not overlooked by neighbours.
SAVING MONEY
There are ways to cut the cost of your extension if you’re willing to compromise on some details. You might choose a method, such as brick and block, that’s familiar to trades and where the materials are readily available. Or why not leave brick walls exposed internally so there’s no need to get plasterers in? Fitting standard-sized fenestration and doors, planning early and shopping in the sales will also help, while getting hands-on by doing the painting yourself or tackling other tasks is satisfying to boot.
NEW FACELIFT
Choosing a traditional construction method doesn’t mean you need to settle for a dull finish. Cladding your home in a material that creates a distinct separation between old and new allows you to explore new external effects, such as charred timber or tiles, to create something that’s truly unique. Be sure to enlist companies that are experienced in applying special render or unfamiliar materials.
INTERNAL LAYOUT
Now you have the extra space, how will you use it? Deciding what will be sited where early on means that you can design a space that works for you. Are you extending to create more living space, or will it create a larger kitchen with room for dining? Think about where you will place storage and furniture, the way you move around the area and who will use it most regularly.
COMFORT UNDERFOOT
Using the same flooring inside and outside will help create a seamless connection with the garden, but make sure the material works for both spaces. Some natural stone, such as slate, is a brilliant option as it’s durable and has non-slip properties. It can also be laid over underfloor heating inside.
HEATING UP
If you have recently installed a new boiler or are planning to do so as part of the project, ask your heating engineer whether the system will be able to cope with the demands from the new space. It is important that the boiler is sized correctly so that it works efficiently. If you’re extending as part of a larger renovation project, consider fitting underfloor heating for even warmth underfoot. A typical boiler replacement starts from around £2,500 including installation plus new plumbing works.
NEW OPENINGS Adding a side extension changes the external appearance of the property and could eliminate a side door or window. It is common to install a floor-to-ceiling fixed pane on the rear elevation of the new section to provide lots of natural light and make an impact. You can opt to swap out the existing rear door to the garden and open up to fit sliding or bi-folds. Even standard French or patio-style doors can work wonders for the aesthetics of an extended home and make a better connection between inside and out.
COST IMPLICATIONS
Costs will vary across the UK, but you can expect to pay around £1,500 to £1,900 per square metre for a single-storey side extension that is of a standard quality. For a higher quality finish, expect to pay within a region of around £1,900 to £2,200 per square metre and between £2,200 to £2,400 per square metre for something more luxurious.
STICK TO THE PLAN
Make sure that you’re happy with your approved plans and stick to them, as the costs of avoidable last minute changes can add up. As with any renovation project, unforeseen issues can occur, especially with period or heritage properties. Being prepared will help mitigate against these, and having a contingency built into the budget is highly recommended. It will save time and money if you finalise the scheme before you start work on site.
BRING IN A PRO
Employing an architect or designer could save you money and time as these professionals know the ins and outs of what makes an extension project work. They can guide you on materials that will complement the style of the property and have experience of working with the local council to help push a particularly creative design through. A designer or architect will be able to maximise the space and come up with suggestions that you perhaps hadn’t considered.
