Double-storey extensions in Meriden

Planning your two-storey extension in Meriden

Planning permission from Solihull Council is the first hurdle for most double-storey extensions in Meriden. Householder applications have an eight-week target for a decision, and Building Regulations approval and the Party Wall Act may also apply.

Councils often expect a side extension's first floor to be set back from the front wall, with its roof below the main ridge.
New first-floor bedrooms normally need an escape window with at least 0.33 m² of clear openable area.
The householder planning fee in England is £548 from April 2026, paid to Solihull Council when you apply.

Which option fits your home?

Building over an existing extension

Adds a first floor on top of an existing single-storey extension or attached garage. It can cost less because the footprint already exists, but a structural engineer must check the existing foundations and walls first, and they sometimes need strengthening. The old flat roof comes off and the new floor is tied into the main house.

Combined side and rear

An L-shaped two-storey build wrapping the side and back of the house gives the biggest gain, sometimes two extra bedrooms. It's a substantial project with more steel and a complex roof junction, and it will need a householder planning application. Expect a longer programme and a careful plan for keeping the house secure while the roofs are joined.

What does your two-storey extension cost in Meriden?

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.

Will I need permission from the council in Meriden?

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.
