House Extensions in St Albans

We design all types of extensions for St Albans homes: single storey rear extensions that open onto the garden, double storey extensions for growing families, side return extensions that reclaim wasted space, wrap-around extensions for maximum impact, loft conversions that add bedrooms and value, kitchen extensions with open-plan living, and basement conversions where ground conditions allow.

Every design is developed around your property's specific structure, orientation, and the character of the St Albans streetscape. We use 3D visualisation so you can see exactly how the finished extension will look and feel before any work begins on site.

Many extensions in St Albans can proceed under permitted development rights without a formal planning application — but this depends on your property type, location, and the scale of the proposed works. We assess this during our free consultation and advise on the simplest route to approval.

Where a full application is needed, our planning team prepares all drawings, design and access statements, and supporting documentation for submission to Hertfordshire County Council. We manage the process from start to finish, including responding to officer queries and negotiating amendments if required.

Building regulations sign-off is essential before you can use your new St Albans extension. We produce detailed construction drawings and specifications that cover all regulatory requirements — from foundations and structural steelwork through to insulation values, fire resistance, and drainage design.

Our team also manages the building control process on your behalf, scheduling inspections at key stages and ensuring that any site variations are documented and approved.

Choosing the right team for your St Albans extension makes all the difference. We bring a blend of architectural creativity, planning strategy, and construction knowledge that ensures your project succeeds on every front — design, budget, and programme.

We have worked with homeowners across St Albans at every scale, from compact kitchen extensions to full double storey builds. No matter the size of your project, you get the same high standard of service and attention to detail.
