Reviews
APT remodelled my entire house to an excellent finish. They added a rear and side double storey extension. They were fantastic I am extremely happy with the result. They stuck to the time frame we agreed and were very helpful with ideas. Angus the site manager was hard working. I have recommended APT to some of my friends who are looking to do similar projects. We will be having our loft done at some point so we will for sure use APT again. Loft Conversion Build

End of Terrace / Semi Detached Loft Conversions

Most end of terrace conversions are very much the same as if the house was located mid-terrace. Howerver there are some exceptions where the gable end can have a sloping hip end.

Regardless these loft jobs have the same guidelines and are simple straight forward as APT have carried out over 60 of these type of projects.
