Footings are soon to be laid. No passageways, other than a central courtyard through which we'll go from one side of the house to the other. Doorways between some rooms. Opening sliding glass panels for the courtyard 'ceiling' (which will also have flyscreen on the bottom layer.) All should look good! Had a clitch with a crooked contractor for underfloor heating and solar hot water with Latendo system. Hopefully we'll find a better one soon.
