2/ 房子原来建的是三个卧室,被现有主人改成四个卧室。我买完以后,要把卧室再改回到原来的三个卧室----报价500-1000英镑。只负责改结构,不负责墙面装修等等。
I think the wall between the two bedrooms you want to merge, is just plaster boards. It should NOT be a supporting wall for the ceiling. If you know it for sure, you could knock it down yourself. Take away the bedroom door, put in plaster board, skimming it. A plaster could do all this in a day. It should not cost you more than £400.
My lg's parents did the same thing as you, to get a building firm in to refurbish their bath room, same work as ours, We spent £5000, they spent £8000. It is true they did not have much hassle, but we did not have much trouble by buying the bathroom suit, the tiles, flooring , and the trades men we know to do it. Well worth the saving of £3000.
Hope this helps
