We have a four bedroom house but one bedroom is really small. We've been looking at options and decided to move, but looking at the market we'll be paying moving costs and stamp duty etc for just a slightly larger fourth bedroom, and probably have to do work to the rest of the house to get it the way we'd like.
We've got a big enough garden to have a garden room at a little distance from the house, and had been thinking of one but we are OK for living space. I've found a company that for less than it would cost us to move does fully liveable garden rooms, including sorting out the planning for you. It would be ideal for us with a child about to go to university so very happy to have a space to chill with their own bathroom.
But would you buy a house with this as a 'fifth bedroom'? Or would it put you off?
