Side extension

Side extensions are an excellent way to maximise underutilised space, whether upstairs or downstairs, adding valuable functional living areas to your home. When planning a side extension, the most important factor to consider is the available space. It’s generally recommended to maintain at least a 1-meter distance from your neighbour’s boundary to comply with regulations and ensure privacy.

A common mistake homeowners make is underestimating the impact of the extension’s width. Remember to account for 350mm for the extension walls plus the 1-meter boundary gap—this represents the maximum buildable width under building regulations. Additionally, some side extensions require significant preparation, including steel reinforcement or even relocating staircases, so it’s crucial to understand the scope of work involved.

If your side garden or land is limited, carefully evaluate whether a side extension is the best option or if alternative solutions might better suit your needs. We recommend starting with a free phone consultation with one of our experienced design team members. This can be followed by a no-obligation design survey to assess the feasibility of your side extension project.
