Self Build & The Walter Segal method

I was involved with two Walter Segal method self build projects at Green Architecture. The experience and simplicity of the construction method has stayed with me.

Segal’s method involves simply-constructed timber frames with bolted connections which eliminate wet trades such as bricklaying and plastering. The system has been designed to ensure that potentially problematic construction issues such as tolerances and thermal movement are accommodated without complex construction details.

In summary, the principles of the Segal System are:

• A pervasive attitude of rigorous simplification.

• Timber, bolt-together, post-and-beam-based construction.

• The majority of the work can be undertaken by a single person with basic carpentry skills (although assistance may be required for roofing and services).

• The use of only basic tools e.g hammer, saw, plane, spade, drill/driver etc.

• Use of readily-available materials in standard sizes, so there is minimal cutting and waste.

• Typically, 600mm x 600mm concrete pad foundations under posts, so strip foundations are not required, and concrete usage is reduced by around 20%.

• No oversite concrete is used – the ground floor stands above the ground.

• No wet trades are required.

• Can accommodate higher insulation levels.

• Easy to extend.

• Proven to work up to three storeys.

• Can achieve Passivhaus or zero-carbon levels.
