Ask an Extension Builder
Our vetted professionals answer your home improvement questions
- Hi, what is the basic prize of an extension per sq m ? what does it include ? how do you know if the tradesman chosen doesn't over charge you? and how to you pay the job before or end of the work .
- Idea of cost for second floor extension only
- Tying in to existing brickwork/ continuous cavity in new + old walls
- Does anyone know of a user friendly estimating software for extension or small build costing that is designed for a small to medium sized company?
