Back filling the floor spaces.The floor spaces between the runs of ground beams were filled in using the leftover earth from the footings and some of the earth that came out of the hole for the swimming pool.jazzmanFeb 17, 2007

Compacting the back fill.Once the floor areas between the footings had been filled with the leftover earth from the foundations, it was compacted every 10 cm. This is essential, as this will be a support for the concrete floor until it has fully cured, a process which will take a t least 28 days.
Thai builders don't think about doing this, and these had never used one before. This one costs about 25,000 baht to buy, but you can rent one for the duration of your construction for about 500 B.

Protecting the concrete.In the tropics it is indispensable to prevent large pours of concrete from drying out before it cures. We covered the freshly poured ground beams with rice sacks which we drenched with water and kept damp for a week.

Formwork for ground beamsThe brickwork form for the beam gets a final height adjustment with a row of red bricks. This is much cheaper than using wooden formwork. It stays in place and adds enormous strength to the beams, and provides the 'plinth' that can be seen around the base of the house.

Foundation of a column.The hollow core is filled with concrete at the same time as the footings are filled ensuring a contiguous pour of the entire matrix of footings and their foundations. The floor of the hole was lined with PVC damp course and the walls of the hole will be lined too. Another solution to keep the damp out of the foundations is to paint the masonry with bitumen.

Formwork for the window sills and lintels.The lintels were concrete which contained 2, 3-hun reinforcing bars.

concrete formwork office windowThe full width bay windows of the office and the master bedroom are based on five sides of an octagon. We wanted the corner pillars between the windows to be as narrow as possible, but allowing the wall to be an additional support for the relatively heavy tiled octagonal roof above.

brick formwork for ground beamsInstead of using expensive wooden shuttering, the formwork for the beams is built at ground level with the Thai 'cinder' blocks. These are extremely cheap, and they stay in place afterwards thus adding even more strength.

roof tile battensThese galvanised steel W-section battens will take special self-tapping 'Profast' screws straight through from the tiles. Other 'Profast' self-tapping screws are used to screw them to the rafters. They can tap into the 3.3 mild steel obviating any predrilling. These battens have the huge advantage that laying the tiles is a one-man operation. Thais usually anchor their tiles by passing copper wire through the screw hole with a man underneath to do the tying.jazzmanFeb 14, 2007

sau romain, fixing the capitalContemporary Thai architecture favours fake Roman columns. (Like the Brits with their pseudo Edwardian porticos, some people love it, some find it totally kitchy - problem is, you can't choose and build your own house in the UK). Some local Thai workers refuse to build to any other design. We refused to be pressured into Doric columns at over 5,000 baht each, we used concrete drain pipes to have Tuscan pillars.

formworkFormwork for the 18 colums. It had cost us roughly 1,000 baht in wood per column. But wood for a house like this would normally be about 30,000 baht, a major consideration in a low budget project. This picture resembles some kind of mediaeval battle engine.
