Builders in Fair Oak & Horton Heath: Extensions & Renovations

Yes. We work across Fair Oak, Horton Heath, Pembers Hill Park, Crowdhill and Fishers Pond, and into Bishopstoke, Eastleigh and Durley. The village is about twenty-five minutes from our Southampton base, and we have completed a full house renovation for a client in Eastleigh next door.

Most single-storey extensions in Fair Oak land between £60,000 and £130,000, and double-storey extensions between £100,000 and £220,000, depending on size, specification and whether a kitchen fit-out is included. Loft conversions typically run £30,000 to £60,000 and garden rooms from around £15,000. You get a detailed written quote, broken down line by line with VAT stated, before anything starts.

A single-storey extension typically runs twelve to sixteen weeks on site and a double-storey extension sixteen to twenty-four weeks, with design and any planning process before that. A loft conversion runs six to ten weeks and a garden room two to four. You receive a written programme with every stage dated and weekly updates on site.

On the older estates, often not for a single-storey rear extension, as many fall within permitted development under Eastleigh Borough Council and Fair Oak has no conservation area. On newer developments such as Pembers Hill Park and One Horton Heath, permitted development rights are frequently removed by planning condition, so an application is usually needed. Building regulations sign-off applies either way, and we handle the application if one is needed.

Yes. Garden rooms, home offices and gyms are popular on the newer estates where the house itself is modern but a separate workspace is missing. Many fall under permitted development if they stay within the size, height and position limits, though on new-build estates with removed rights an application may be needed. A self-contained annexe for someone to live in almost always needs planning permission. We tell you which applies at the site visit.
