Walter Segal

Walter Segal (1907 – 1985) was an architect who developed a system of self-build housing, the Segal self-build method. Based on traditional timber frame methods modified to use standard modern materials, his method eliminates the need for wet trades such as bricklaying and plastering, resulting in a light-weight method which can be built with minimal experience and is ecologically sound. The roofs tend to be flat with many layers of roofing felt, which allows the creation of grass-covered roofs. Foundations are minimal, often just paving slabs, the strength coming from the geometry of their construction. Segal houses have been compared to traditional Japanese houses.

Segal was born in 1907 and grew up in Berlin, Germany, as the son of the Romanian Jewish painter Arthur Segal, but spent the time of the First World War in Ascona, Switzerland close to an alternative community called Monte Verità (McKean: 1988). Walter Segal studied architecture among the pioneers of the Modern Movement in Berlin and Delft, Netherlands, and received his first commission in 1932 from a patron of his father, Bernhard Mayer, to build a small wooden holiday cabin in Ascona.

He moved to London, UK in 1936 where he met and eventually married Eva Bradt, a student at the Architectural Association School of Architecture. He taught at the school, wrote in trade journals, published a couple of books and had a few small architectural commissions. They lived in Highgate, London, and their son, John, was born in 1948. By then Segal had built his first main building, which was a block of flats in south London. Eva died in 1950.

In 1963 Segal married Moran Scott, who also lived in Highgate. To gain more living space, they eventually demolished and rebuilt Scott's house. They built a temporary structure in the garden using standard cladding materials and with no foundations other than paving slabs. It took two weeks to build and cost £800. This house, dubbed the "Little House in the Garden", roused considerable interest and led to a number of commissions using a similar style around the country. As the system developed the clients were able to do more and more of the building themselves.
