Hi, I'm looking to build a potting shed in the garden, with a lightweight lean-to greenhouse on the side. The shed itself will be about 2.4m square, with a 1m wide door-way opening at the front, 1m wide window on the left side and 1m wide door way on the right side that will lead into the...

Roof design aside, I'm considering whether to have the inner skin of the second story built in blockwork, or to have a go at building it timber framed myself (purely to save cost). The outside will be a brick skin in any case and the existing cavity is 50mm. If the inner skin is blockwork then...

Hi Woody, thanks for your reply. This will be my third DIY extension with a cut and pitch roof so although I will be drawing plans and getting full plans approval, I'm hoping not to need an architect. I like the idea of purlins on struts on timber beams (I presume that this timber beam would...

Hello all, I am new here so hoping this is in the right place. I'm looking for some advice regarding timber sizing for a roof: I plan to build a room on top of an existing attached garage. The overall dimensions will be 5.5m wide x 8m long (brick and block with 50mm cavity). The room will be...
