Planning Your Single Storey Extension
A successful extension begins with careful planning. Local Wandsworth regulations allow for permitted development rights, which often mean you do not need full planning permission if the extension meets size and design criteria.
Here are important points to consider during planning:
-
Roof Design – Flat or pitched roofs are popular choices. A flat roof can create a contemporary feel, while a pitched roof can match traditional designs.
-
Materials – Brick, timber, and glass are commonly used in Summerstown extensions. Choosing materials that complement your existing property ensures a cohesive look.
-
Layout – Decide how the extension will function. Do you need a new kitchen, larger living area, or a home office? The layout should make everyday living more comfortable.
-
Lighting – Maximize natural light with large windows, bi-fold doors, or roof lanterns. Well-lit spaces feel more welcoming and open.
-
Budget – Single storey extensions vary in cost, but clear budgeting helps prevent unexpected expenses during construction.
Working with a local builder experienced in Summerstown extensions ensures your plans comply with regulations and are executed efficiently.
