Which options suit homes in Balsall Common?

Two-storey side extension

Built over the side of the house, often where a driveway or old garage sits. It can create a garage, utility or study downstairs with a double bedroom above. Councils often expect the upper floor to be set back from the front and the roof to sit lower than the main ridge, so the design needs care to win approval.

Mixed-height extension

A two-storey section at the side with a single-storey section running across the back. This keeps the first floor away from neighbours' windows while still giving a wide kitchen-diner below. It's a practical compromise where planners have concerns about a full-depth two-storey rear extension, and it often simplifies the roof.

Which postcodes in Balsall Common do you work in?

We cover CV7 and the streets around them. If you're on the edge of Balsall Common, neighbouring Tile Hill and Meriden are covered too.

Can we stay in the house while you build?

Most families do. The early stages are outside, and the existing house stays closed off until the shell is weathertight. The harder weeks are when openings are cut through on both floors, which brings dust and noise into bedrooms and the kitchen. We sheet off openings, lock up securely every night and agree in advance which rooms you'll lose and when.

Who approves double-storey extensions in Balsall Common?

Usually both. Most two-storey extensions need a planning application to Solihull Council, and the structural work needs Building Regulations approval from its building control team or a registered building control approver.
