We’ve recently been appointed on two new projects with Hexzagon Developments.
At the former Runwell Hospital in Essex a large residential development is being constructed. We’re working on the old Administration Building. This is a fairly robust 2 storey 1930’s block with hollow pot floors and brick masonry walls. Converting this into 8 apartments is relatively straightforward; until you come to the roof…we need to add an extra floor. The roof is a complicated steel truss system that will need to be chopped about in order to accommodate the new floor and windows.
The scheme also includes the addition of 2 new wings which include 6 duplex units. These are elevated above the ground floor parking undercroft. We’ve used a steel frame for the ground floor structure and then suggested a timber frame at first and roof to keep the loads manageable.
At Tudor Road in Hackney we’re designing a 5 storey, steel framed, mixed use building. This includes 10 residential units and commercial space at ground floor. The desire for clear spans at the ground floor means we have to incorporate some transfer structure at first floor; we have also spent some time rationalising the stability bracing so that it can all be concealed within the cladding zones.
A steel frame seems the logical option here because of the complicated load paths; we’ve used hollowcore planks for the floors which bear on ledger angles or the bottom flange of the beams. This keeps the overall floor depth reasonably compact.
Both projects should be on site in January 2017.
