The Home Engineers were responsible for the full structural design package associated with these two beautiful new build dwellings situated in Ponteland, Northumberland.
The design comprised of a load bearing masonry structure which provided support to the 1st floor and roof. Due to the relatively open plan arrangement at ground floor level the provision of structural steelwork was required to support timber floor joists and masonry walls at 1st floor level. Apex structural steelwork was also required to achieve the floor to ceiling glazed facades to the front and rear elevations.
The roof structure design was the main challenge due to the requirement of internal vaulted ceilings throughout the 1st floor level. Vaulted ceilings meant that the traditional mechanism of providing lateral restraint using flat ceilings was not possible. Therefore it was necessary to provide a solution to resist against the lateral reaction at the head of the external wall. The solution we adopted was the provision of steel ridge beams to support laid in timber roof rafters with plywood fixed to the underside to create a rigid diaphragm. This would mean that the roof would act like a robust beam spanning between external walls and would have the capacity to resist against the lateral reaction at the head of the wall.
