Covering Havant
Havant is about 19 miles east of Southampton. We also cover Waterlooville (3 miles to the north-west), Portsmouth and Gosport.
Homes in the South East
Many South East homes are inter-war or post-war semis and detached houses with room for rear and side extensions, while historic town centres and villages bring conservation area and listed building controls.
What do you get with an upward extension?
The first question is whether the existing walls and foundations can carry the extra load, so we start with a structural survey. Then we design either a full first floor or a raised roof with dormers, handle planning or prior approval, and build the new storey while protecting the floor below.
- Design and planning or prior approval application
- New first-floor structure, walls and roof
- Full fit-out of the new rooms
What will an upward extension cost?
Guide prices for bungalow and upward extensions, including VAT where it applies. Your fixed price is confirmed in writing after the survey.

| New first floor, standard specification | £2,200 to £2,800 per m² |

How is an upward extension approved in Havant?
In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.
In England, Class AA permitted development allows an extra storey on many detached and semi-detached houses built between July 1948 and October 2018, subject to a prior approval application covering design, neighbours’ amenity and other matters.
What should Havant homeowners check first?
- The house is exposed while the roof is off, so the sequence is planned tightly.
- Neighbours’ light and privacy are the main planning tests.
From first call to completion

- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
