Irwin Crescent, Belfast 

After completing the single storey rear extension for Mr. and Mrs. B I was asked to help them convert their roof space. When converting an attic it's important to get the details correct, helping your builder understand exactly what is required to meet Planning / Building Regulations including insulation, ventilation & structure. Conversions are not as simple as many believe. This project offered limited space and headroom but with my help it turned out superb. Check out the photos.
