Single Storey Extensions in Solihull
What is a single storey extension?
A single storey extension is a single-level addition to your home, built at the rear, to the side, or wrapped around the side and rear. It is one of the most popular ways to add usable ground-floor space without the cost or disruption of building upwards.
- Rear extension: projects into the back garden, ideal for a larger kitchen-diner.
- Side-return extension: fills in the narrow alley down the side of the house.
- Single-storey wraparound: combines a rear and side-return into one L-shaped space.
Typical uses include a bigger kitchen or dining area, extra living space, or a home office or playroom.
Why choose a single storey extension in Solihull?
- No planning permission is needed in many cases under permitted development, so it is faster to start than a double storey extension.
- Lower cost than a double storey extension for the ground-floor space added.
- Minimal disruption to the existing roofline and to daily life during the build.
- FMB-registered, fully insured, with over 20 years building in Solihull and the surrounding areas.

Our process and timeline
- Step 1: Free consultation and site visit. We visit, measure up and talk through your ideas and budget.
- Step 2: Design and drawings. We prepare the drawings for your extension.
- Step 3: Planning permission or permitted development check. We confirm exactly what your property needs and handle any application.
- Step 4: Build. Groundwork, structure, roofing, first fix, second fix and finishing.
- Step 5: Sign-off and completion. Building control sign-off and a final walk-round with you.
Typical build time: 10 to 14 weeks on site (UK average). The design and planning stage happens beforehand and usually adds six to eight weeks.
Do I need planning permission for a single storey extension in Solihull?
Single storey rear extensions often fall under permitted development. As a general guide the depth limits are up to 4m for a detached house and 3m for other house types, or up to 6 to 8m under the Larger Home Extension scheme, which is subject to a neighbour consultation. Always verify the current thresholds against Solihull Metropolitan Borough Council’s specific rules before you begin, and we will do this for you as part of the project.
