A major refurbishment of one of the earliest steel framed houses in Britain

In 1962 young architect Michael Manser (1929-2016) designed one of the first steel-framed houses in Britain, dramatically cantilevered over a hillside in Godalming, Surrey. The steep site provided Manser with an opportunity to demonstrate the benefits of steel construction, with the Meccano-like house built on a modest budget and completed in just half the time of a traditional masonry house.

Sixty years later, his son Jonathan Manser of The Manser Practice was approached by the new owners to undertake a major refurbishment of the house. But by 2022, the house had fallen into disrepair. Water ingress had severely damaged the floor and roof build-ups, there was rotten timber, asbestos, and one of the foundations had slipped which had led to distortion in the steelwork. This meant that the house had to be completely stripped back to its steel frame to allow structural repairs to be carried out. This provided an opportunity to add thermal breaks, where possible, to the steel frame, which was repainted and expressed externally to preserve its original character.

The energy efficiency of the house has also been significantly improved by completely re-cladding and insulating the facade, replacing the original gas boiler and fireplace with air source heat pumps and underfloor heating, and replacing the existing single glazed windows with new thermally broken fixed glazing and opening façade vents to assist with natural cross-ventilation.

Internally, the clients wanted the house to be primarily lived in on one level. To achieve this, the original upstairs bedroom and study have been converted into one large master bedroom suite. On the lower level, four children’s bedrooms have been converted into a snug and a spacious guest suite, accessed separately from the floor above via a new external staircase. Relocating the stair from the centre to the side of the house has increased the size of the main living space, and links the kitchen to a new external terrace.
