Garden rooms, extensions & lofts in Ferndown

Ferndown and West Parley are extension country: large post-war plots, wide frontages and rear gardens with room to spare. If you have space to go outwards, this is where it usually makes sense.

Building in Ferndown

1960s and 70s detached houses dominate, which means straightforward cavity walls, accessible foundations and few surprises once we open up. Side access is usually wide enough for a machine, which shortens the groundwork phase considerably.

Local planning

Dorset Council. Permitted development is generous on most Ferndown plots, though a handful of roads carry restrictive covenants from the original developer, so check your deeds as well as the planning rules.

The build-over agreement was the bit we dreaded and Thicketts just dealt with it. Nine weeks start to plastered.

The Baker family · Kitchen extension, Ferndown

Wide side access meant a machine and it flew. Three weeks and I was hitting balls in it.

Graham T. · Golf room, West Parley

Fixed price genuinely stayed fixed. First builder we’ve used where that was true.

Ferndown questions

On most plots, yes. Large post-war gardens and wide frontages give you plenty of room inside the rules. Worth checking your deeds too: a handful of roads carry restrictive covenants from the original developer.

It genuinely does. Most Ferndown plots take a mini-digger, which cuts days off the groundwork phase compared with barrowing everything by hand.

If you have the space to go outwards and want the room connected to the house, extension. If it wants to be separate, whether that is an office, a gym or a golf room, the garden is cheaper and faster. We’ll say which we’d do in your position.
