About us
Two-storey extension specialists, part of the S&K Group in Birmingham.

Who we are
Two Storey Extensions is a trading name of S&K Property Investments and Improvement Ltd, company number 16932889, registered at Unit 1 Hembs Crescent, Great Barr, Birmingham B43 5DG. We are part of the S&K Group, a family of construction and property businesses based in Birmingham.
We focus on one thing: extensions that add a second storey. That means two-storey rear, side and wraparound extensions, rooms over garages and first floors on top of existing single storeys, along with the design, planning, structural and building regulations work behind them.
How we work
Your contract is with S&K Property Investments and Improvement Ltd, which manages the project and invoices the work. The building work is carried out by vetted teams working under S&K, overseen by one project lead. Structural design is by independent structural engineers, and approvals come from your council or a registered building control approver.
What we won't do
- Publish made-up reviews or testimonials.
- Show computer-generated photos as if they were our projects. The images on this site are computer-generated to show typical designs.
- Quote a build price before the design is agreed. Guide prices are guides; fixed prices come in writing.
- Apply England's rules to a house in Wales, Scotland or Northern Ireland.
