I'm ready to start a loft layout, having ummed and arred for a number of years, and looking for some advice on the baseboard.
What I'm thinking is to span the entire width of the house, across 15'6", using 175 x 22 timber hung on joist hangers fixed to the end walls of the house, to reduce the weight on the floor, possibly with a leg or two in the centre to provide more vertical rigidity. There will be two pairs of parallel joists, approx 10' apart, tied together with more timber towards each end to provide a "roundy-roundy" layout, all topped with 9mm (?) ply.
Has anyone any experience on doing it this way that can point out any likely pitfalls?
And how often would you, wise reader, suggest putting cross members between the parallel joists to support a baseboard width of around 27"?
