How to build a lean-to glasshouse
Step 6. Make up the roof frame
Make up the roof frame according to the plan on the previous page.
The length of the roof frame is the same as that of the high wall (the working platform), so if you fix a couple of blocks each end of the working platform,
it will contain the length of the roof frame.
Refer to 'HOW TO - Cut rebates and trenches' on page 16.
Cut the rafters to length, angle cut the ends, rebate where required (refer to previous page plans), space them out, fix the noggings, the top fascia board, and the bottom packer board. Take notice that one corner of the packer board needs to be chamfered. Refer to the plans for all other details. Space the noggings to suit the glass sizes.
