Tailored Extensions to Suit Your Property

Whether you’re renovating a modern home, a period property, or a terraced house, our team adapts designs to match the existing architecture and maximise your investment.

Modern House Extensions: Clean lines, energy-efficient materials, and open-plan layouts.
Victorian/Edwardian Homes: Sensitive to original features, materials, and scale.
Semi-Detached or End-of-Terrace: Leverage side and rear space for impactful results.

Planning Permission and Building Regulations

Most single storey extensions fall under permitted development rights, meaning they don’t require full planning permission. However, larger or two-storey builds may.

We guide you through:

Planning Permission Requirements
Party Wall Agreements
Building Regulations Compliance
Structural Calculations and Sign-offs

Our experience with extension builders near me ensures all permissions are properly handled.
