Fist grate has been built and mounted. It looked fine, so we decided to continue by the same way.
The summer house is on the hill. For the higher basement we had to choose hevier material and we changed the green colour to brown. This is a virtual model to study how this material, colour and style would work there.
First pieces have been mounted here in this picture. circular saw was a must to cut the material into correct measures in such a high a mount. Every module consists of around 50 cuts and there were 14 modules which makes at least 700 cuts + those tiny parts between makes 1400 -1500 pieces as total.

Before the east end of the basement could be covered. I had to isolate and build walls for the water supply system seen on the left.
These walls will be easy to take off from three sides for mainenance work and to change the filters. Isolation foam was sprayed to cover very tight places like under the tanks etc. The carbon filter for the radon gas had to become covered by a lead plate to avoid radiation.
The floor was not stright. One corner had to become built and isolated down level because of the pressure tank had been mounted lower than other parts. Here it had been risen allready 10 cms. to let the water run below and to get space for the isolation.
It took allmost two weeks to get the hood ready. I needed to do some plumbing and electricity maintenence as well. Isolation work was neither very easy by two fold plating with several holes and without any way to let the wind inside.
Every grate module had to become built on sright surface because when ready, it acted like "full wood plate" and there was nothing to do if it were not stright when ready.

This grate module was wet and weighted more than 100 kilos. It had to dry more than two weeks before I could move it down to its place. The terrain was running on varying levels and I had to form the grate to follow the surface. This is the reason the grate is a bit higher on the other side. The grate is lying upside down here.

Every module were hinged so that they can be opened and one door had to be made for easy access. More than 1500 screws were screwn and 1,2 kms of wood lath were used. Anyhow its all ready now. The work took whole the summer.
