A Guide To Building A Side Double Storey Extension

From Planning To Designing To Building

When a rear extension is not an option due to lack of available space, but homeowners have unused space down the side of their property, a side extension is a perfect solution. This means that you maximise all your land, and your property will reach its full potential.


Depending on your plans, you may qualify for permitted development rights, so you will not need to apply for planning permission. However, the rules for permitted development are strict. If you must apply for planning permission, this can take longer and requires the council to approve your plans. A Designer can draw up planning drawings and a Design & Access statement to share with the planning officers. You should apply for Building Regulations Approval; the application should contain building regulations drawings, structural calculations, and specifications.


You will need to find a skilled designer who will work with you and your vision to design your extension. The key is pinpointing what you feel is necessary to improve your family life. Is it an open plan living area, a kitchen diner, an office, or a utility room? Consider whether you would benefit from an additional bedroom with an en-suite, a family bathroom, walk-in wardrobe, or playroom. The possibilities are endless and unique to your specifications.
