materials as well as the structural needs of the building.
If you take time to have a look through the Excellent AJ article on Walter Segal, you might want to take time and review his explanation of this grid. It’s not the usual grid you might expect to find on a house or for that mater any other Architectural project I have ever worked on in 45 years, and consist of a smaller tartan grid fitting within a master grid.
Walter segal houses were, or are, made with as little waste as possible, materials used are fitted whole, not cut, hence the tartan grid, which is used to control the main materials and they are intended to fit between the main structure grid.
Lets start with the smaller tartan grid, which is made up of a 600mm wide larger spacing with a 50mm wide space between. The 6000mm wide space being the width of a plaster board. The 50mm space is for the secondary structural stud, which always shows through in Walters designs, a point you might like to re consider in a modern house.
The larger grid would be made up of module of the smaller unit, limited by the span of the floor joist, I like the idea of a three or four material tartan modules to the main structural grid of the main support frame, if I keep both grids with a 50mm small gap, this will allow easy planning of the interior fitting in with the smaller internal walls.
The point of this review of Walters grid is to make you think about how you might approach the same problem given modern materials and structural requirements. I still like the idea of this grid, but would look at a 1200mm wide plasterboard, and a 75mm wide stud to both the secondary and main structure, looking at a 150 x75, with a 200 or 225×75 main structure. This defiantly needs some play time looking at the various permutations and layout possibilities, and how easy each would be to install, given that most of his house types are self build.
