Construction of the house

The central structure of the house is based on a square of nine columns each of which are set in the ground about a metre below the base level of the ‘make tall’. There are feet on each column that adds to the stability. Below ground and the ground floor the columns are made from concrete, but in the first floor and to the roof a wooden column is joined to the concrete. The columns are tied into each other at three points; ground level, first floor level and ceiling level of the first floor. That seems to provide the house with stability and everything else is tied into this cube structure. The ground floor is currently made from the soil of the ‘make tall’, but it will be filled in with concrete and wire mesh for strength before the floor tiles are laid. My hope is that by this time the soil will be stable enough to take the weight. Basically construction in this style has been going on for decades so it must work!
The outside walls on the ground level are breeze block with a concrete rendering both inside and outside which will be painted over. The inside walls on the ground floor are made from bricks about a quarter of the size of UK bricks and very roughly cemented together then rendered. The base being the lintel that ties in the columns so it should be reasonably strong. Upstairs all the walls are made from wood or a composite that is made to look like wood. There isn’t really any load bearing except the brick walls of the bathroom.
The roof is made from steel which sounds really good when it rains! You may have guessed from previous photos but I can confirm it is blue.
