At an early stage it was decided to go the self-build route. The client had family members who were involved in the building industry, and a local engineer was engaged to project-manage the building. It was very important for us to achieve an “A” rated home so we looked at all the options available to us to achieve this. One of the most important elements of achieving this is the level of airtightness that has to be adhered too. After careful consideration it was agreed we would go down the route of timber-frame construction. We sent the drawings to tender, and after careful appraisal we appointed Kingspan House.
