Ideas for Single Storey House Extensions

Kitchen Extensions

The kitchen is the heart of the home, with the average adult spending over 1 hour a day in this part of the house. That’s why kitchen extensions have become one of the most popular single-storey rear extensions among homeowners.

Investing in a single-storey extension to expand on kitchen space provides an opportunity to create a vibrant new design and unlock the true potential of your house. With the ability to utilise your permitted development rights, it’s never been easier to create a space that works for you and your family both emotionally and practically.

The Extension Architectures’ design team can help bring your goals to life with planning permission, layout plans, and kitchen extension cost. As experts in planning permission for kitchen extensions and bespoke kitchen design, we have the professional experience and collaborative team to produce the perfect space for you.

Wrap Around Extensions

Go one step further with your single-storey rear extension and design a wraparound extension to create an open and more flexible living space for every occasion. A wraparound extension wraps itself around the original building in an L-shape. Due to this, it will require a householder or complete planning application and subsequent approval from your local council.

Wraparound single-storey extensions in London & Surrey are one of the best ways of creating additional space and adding value to your home without a heavy financial burden, with open plan living arrangements and lots of natural light ranking as two of the top 10 most desirable features for potential buyers. Not only does it add significant value at a lower cost, but the potential space-gained for cost per square meter is unparalleled when compared with double-storey extensions or loft extensions.

Frequently Asked Questions about Single Storey Extensions

On the one hand, the design aspect of a single-storey extension project can be fun but coming up with general costs and budgets can be complex. The general cost of your extension will ultimately depend on your brief. However, some general costs for a single-storey rear extension can be summarised as follows:

– UK Average sqm: £ 1,200

– London Average sqm: £ 1,400

These are general costs for an average quality extension. The higher-end projects cost in London can go up to 2,300£ sqm.

The use of your extension will also impact costs. Having an idea of how much you are willing to spend on a new kitchen or a new bathroom will be crucial when planning the price for your new project. Bathrooms and kitchens are trickier to budget than a bedroom or a living room as there is plumbing to consider and appliances and fittings. The cost of adding a kitchen to your extension will start at around £10,000 for a cheaper kitchen design. The final price will depend on the quality of the materials and appliances. Adding a bathroom to the project will increase the cost by about £5,000, but this will also depend on the type of finishes you want.

Rule of Thumb: As there are many variables to the costs of your project, it is good to have a general idea of how the budget will be spread and how the costs for professionals will impact the total cost: Architects London average fees 10% / Administration fees: 1% / Structural engineer: 4% / Surveyors: 3% / Contractors:30% / Materials 20% / Fittings 5% / Glazing: 15% / VAT 20%.

Under permitted development, you can extend along the side and separately at the rear without planning permission.

Single-storey rear extensions must not extend beyond the rear wall of the original house by more than three metres (if a semi-detached house) or by four metres (if a detached house). The maximum height of a single-storey rear extension should be four metres to avoid planning permission for an extension.

Side Extensions: Side extensions fall under permitted development if they do not extend more than half the width of the original house. You can extend a maximum of 3 meters if it is a single-storey extension and does not extend past the front elevation.

Research carried out by Nationwide shows how home improvements and home extensions can add significant value to your property. An extension can add up to 23% to the value of your property.
