My folks have a large (50’ long) L-shaped garage, attached to their house, built about 13 years ago, with a pitched tiled roof. These days they are not so well; my mother is a paraplegic and dad has Alzheimers. So they are converting half of their garage into a groundfloor bedroom, so my dad can move downstairs. I thought this would be a straightforward and cost effective job. The plan would be to put in a dividing wall in the garage, knock out an existing window (which has a steel lintel), and make into a french window into the garden, and put in a fixed pane where there is an existing stable door. An existing window will be bricked up, and a door knocked in from the adjoining dining room.
The builder, who has done all the work for them over the years, including constructing the garage in the first place, has come in at £22k, which sounds a lot, as I was expecting ~£10k. This is a verbal quote based off what an architect drew up.
The Constructions notes are below. Does this quote fit with the notes below.
French Windows: £1000
Single full length glazed window; £500
Electrics: £500 (being a garage, there is also electrics in the garage, so its just addition of sockets)
Blockwork: £2000; gap to be bricked up is about 4m wide, so maybe 10 sq meter, or does it need to be blocked the full height of the garage, and not to around ceiling height
Boxing in ceiling: £500
Door from house and Iintel: £1000
Plastering the room: £1000
So I am struggling to get anywhere near the £22k quoted, unless I am hopelessly out of touch about the cost of things these days.
