We design architecture for all: inclusive, barrier free and participatory


steel frame

Guest Blogger Ian McMillan: The first issue of the steel contractor’s drawings have come in for checking after only 22 Formal TQ’s and 14 phone call queries (whilst on holiday in Cheltenham).  There are one or two minor issues we’ve picked up from the drawings – as usual it’s cross bracing (engineers like a lot of this and architects never want any) and connection details.
We had looked at a timber frame, with steel sections – which became a hybrid solution which started to become overcomplex, so we investigated an engineered timber solution which couldn’t be guaranteed to achieve what we needed, so we had to bite the bullet and go for a full steel frame.  It’s not so uncommon on mainland Europe where steel and in particular concrete framed solutions are the norm – but then again they do expect their housing to last more than 25 years.
There are 8 tons of steel being used, which is much more than you would normally expect for a new build this size.  The primary reason is that the ramp cuts through most of the structural lines, and the extend of glazing and large open plan spaces which we needed to do in order to maximise the daylight and spatial flow and connectivity within such a small plot size.  Then when you have a steel frame you might as well use it to its full potential – and introduce cantilevers.
