It's only when one reaches the first floor that the mystery is explained, and the 'suspending' mechanism becomes obvious. At least that will be the case when the floorboards are laid, and the structure is no longer transparent.
Things are certainly progressing. I have now found, and bought, the parquet floorboards (2 metres by 14 cms by 21 mms) that I've been looking for (above is about half the amount), and the excellent 1.14 metre wide staircase is in place, but not quite finished; it will have some aluminium cladding added later.
After the flooring is laid, the next job will be for the windows to be fitted in mid October, then we shall close up for winter and relax.
The circus will all start again in March 2015, when we shall begin to consider the kitchen and bathroom designs, Hopefully Wills, Kellogg, and Bunny (Yo Bunny) will then be here to make all those difficult decisions about style, colour, and kit. Very exciting.
p.s. I will probably make the dining table over the coming winter. It is to be 4 metres long by 1 metre wide. I love BIG dining tables; it will seat 10 in non-elbow-touching, gastronomic, COMFORT.
