Built in 1880 by Matthew Allen, the entrepreneurial builder, Allen Gardens were the first purpose built maisonettes in London. As a consequence of their historic status they are Grade II listed. The buildings were constructed with an innovative design and structure using Allen’s patented floor system. What at first appears to be a form of fireproof floor with timber battens and boards supported off it, has been found to be two separate structures. The floor structure itself is a joisted timber floor spanning over a concrete slab which acts as a ceiling.
We were asked to act as structural consultant for the refurbishment project on behalf of One Housing Group. The works included the conservation of the historic concrete – a key element of the listing, general structural repairs to the 140 year old building and the conversion and modernisation of the flats.
