Hi,

I'm after some conventional wisdom on building timber framed partition
walls. The one I'm going to build will be L-shaped in the corner of a
bedroom to take a sink and hide all the pipework behind it. Size
would be around 0.5m on the long wall and 0.3m on the short wall with
height of 2.45m

My questions a

1) What timber to use? Planed untreated?
2) What size should the uprights be? 2" x2"?
3) What size should the cross-pieces (noggins?) be? 2" x 1.5"?
4) What should the centres be for the vertical and horizontal pieces?

Anything else I should know before starting?

Thanks
Charles

I would use 75x50 sawn (not planed) timber for the framing and noggins -
with the 75 dimension defining the thickness of the walls. You can then hide
most of the pipework *inside* the walls. Use Hep2o for all hidden pipework,
changing to copper for anything which is exposed. You can then feed the
Hep2o through holes drilled in the noggins, floor plates or ceiling plates,
as appropriate.

I would use a total of 5 uprights, with 3 of them being at the intersection
of the two sections - 2 back to back and the other one at right angles (in
plan view). You will then have a face on each wall in the corner for nailing
on your plasterboard. I would use 2 noggins in each section (plus floor and
ceiling plates, of course), approx 1/3 and 2/3 of the way up the walls - but
make sure that there's something solid to screw the sink hangers to.
