Converting an unused extension into flat

castletownman

Right lads, new to these parts, and generally clueless when it comes to home improvement

Anyway, myself and the OH are looking to convert an unused extension in my parents house into a self-contained one bedroom flat. The interior is already plastered, with a stud wall dividing into a front living space, and a bedroom and bathroom to the back. The front part is roughly 20 sq.metres in area, and the bedroom approx. 11 sq.metres All the electricity cavities and wires are there already, not connected to any power supply yet.

It was initially built as part of a two-storey extension to the house, with the top storey the parents new bedroom and the bottom left idle since. We are talking around 15 years of it just lying there unused, save for plenty of junk being stored in it over time.

Moving the junk is the easy bit- I have worked more than halfway through one pile of it already, and most of the rest is furniture/fittings that can be re-used.

There are radiators installed but obviously not connected to anything- so I have been told that an outer boiler will be the best way to heat them. Anyone have any other advice on this?

Also the original exterior wall from the main house forms one of the walls, so that will have to be studded and plastered. It's about fourteen feet in length, but with a door in the middle, so can't imagine it would cost too much/take too much time to do?

The ceiling needs to be plastered too, and the floor perhaps screed but otherwise than everything mentioned, I can't think of anything else that needs to be done, and its essentially a blank canvas in terms of interior design then.

I suppose I am just looking for a rough estimate of how much it would cost (with wooden floorboards to be laid), and a rough time-frame. Hoping to up and running inside six months

Thanks in advance.

Get some builders out and get quotes.

No one can give you figures based on not seeing it.

Apply for planning permission?

Don't need one? Just doing up an unused room in an extension, where prior planning permission was granted to the original build.

Not true, you're creating self-contained accomodation. It's a change of use.
