We own a ground floor, one bedroom flat in a mid-terrace conversion, and are reaching a point where we want more space. We love East Dulwich and want to stay, but can't afford a bigger house here. One option is to move out of London to commute in, but another is to extend out the back and add an extra bedroom onto the flat. I was wondering if anyone done a similar extension, and what your experience was in terms of: a) Was it stressful, and how long did it take? Did you have to move out for a long period? b) How much did it cost? c)Who did you use? d) Was the cost and stress worth it for an extra bedroom? Any advice would be much appreciated!!
