Architectural design in Southampton
Extensions, loft conversions and commercial schemes across the city, from Bassett and Bitterne to Ocean Village and Above Bar Street.
Local expertise in Southampton
Southampton's housing is a real mix: Victorian and Edwardian terraces in Portswood and Shirley, inter-war semis in Bassett and Bitterne, and modern apartments and commercial units around the waterfront. Each brings its own opportunities and constraints, and we design around them rather than forcing a standard solution.
We have delivered residential extensions in Bassett and Bitterne, and commercial fit-outs and change-of-use schemes in Ocean Village and on Above Bar Street, so we know how Southampton City Council approaches both householder and commercial applications.
Planning in Southampton
Planning applications here are decided by Southampton City Council.
Local planning authority
Applications in the city are decided by Southampton City Council. We prepare and submit the full drawing package and handle queries from the case officer.
Conservation areas
The city has a number of conservation areas, including the Old Town. Work in these areas needs extra care with materials and design, and some permitted development rights are restricted.
Permitted development
Many rear extensions and loft conversions on houses can go ahead without full planning permission. We check whether your project qualifies and can apply for a Lawful Development Certificate for peace of mind.
Building regulations
Every scheme we design comes with a building regulations package, so your builder has the detail they need and building control sign-off is straightforward.

Do you work across the whole of Southampton?
Yes. We work across every part of the city, including Bassett, Bitterne, Portswood, Shirley, Woolston, Sholing and the city centre, plus surrounding areas such as Chandler's Ford, Eastleigh and Totton.
Do I need planning permission for an extension in Southampton?
Not always. Many single-storey rear extensions and loft conversions fall under permitted development, but conservation areas, flats and previously extended homes have different rules. We'll confirm the right route at your free consultation.
Can you help with commercial projects in Southampton?
Yes. Our Southampton work includes restaurant and bar fit-outs in Ocean Village and commercial schemes on Above Bar Street, including change-of-use applications.
