We have a detached garage 20ft x 9ft ish with horrible rotting wooden doors and window frames (actual glass is partly missing too so boarded up.) The cost to replace the windows and doors with basic uPVC would be c £1800. The garage is for storage only due to an extension to the front of the house but still has a garage door which is also on its last legs.
While pricing up to have "like for like" replacements we decided to price up converting to an office and large storage room (say two areas of 10 x 9ft each). All in the quote is c £8000 with heating, electrics etc.
Now, DH (who has started working from home 5 or 6 days per month) says we should go for it. I think the quote is good value and we'll be here for 10 or so years, so my only worry is whether we'll actually use it. It's about 8ft from the back door and would have French doors onto the patio so kind of a garden room feel.
Anyone with a similar set up? I just worry he'll stay where the kettle is!
