Single-Storey Rear Extensions Architect-Designed Home Improvements
Expand Your Home with Confidence
A single-storey rear extension is one of the most effective ways to increase living space, improve natural light, and enhance property value. Whether you’re planning a larger kitchen, a family room, or a flexible open-plan layout, we deliver tailored solutions that meet your needs and exceed expectations.
Planning & Compliance
We manage every stage of the process:
- Assessing Permitted Development rights or preparing full planning applications
- Coordinating Party Wall notices and neighbour consultations
- Submitting Building Regulations applications and liaising with inspectors
- Ensuring full compliance with current Building Regulations and British Standards
Build Process Overview
Our extensions follow a clear, phased programme:
- Site setup and groundworks: excavation, foundations, drainage
- Superstructure: insulated cavity walls, structural tie-ins
- Roof and glazing: pitched or flat roof systems, high-performance windows
- Internal works: first and second fix, finishes, and final certifications
Design That Works
We prioritise:
- Natural light through rooflights and glazed doors
- Energy efficiency with compliant insulation and detailing
- Seamless integration with existing architecture
- Future-proofing for long-term flexibility and resale value
