Ideas for Single Storey House Extensions

Kitchen Extensions

A kitchen extension is a great opportunity to create a vibrant new space to complement any style of home or design taste. As the heart of your home, the average adult spends over 1 hour a day in the kitchen! This means that whatever your aesthetic, a kitchen extension can not only add significant value to your home but also unlock its potential and bring enhanced functionality and emotional benefits.

In addition to this, if you are thinking about adding a new space by means of a side, rear, or orangery kitchen extension, you may even be able to utilise your permitted development rights, meaning you won’t need to apply under a full planning application- it has never been easier to create that much-needed space!

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

Wraparound Extensions

If you are considering extending your home to create an open plan living space, and to provide plenty of flexible space for every occasion, a wraparound extension may be for you! 

Most common on detached homes or Victorian Terraces, a wraparound extension is, as opposed to a side or rear extension, one which wraps itself around the original building. Due to this, it will require a householder or full planning application, and subsequent approval from your local council.

Wraparound 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.
