Frameless Doors and Windows
Door and window frames are not actually required. They are responsible for almost half the cost of timber used. Avoiding frames considerably reduces the cost of timber.
Door planks are screwed together with strap iron hinges to form doors, and this can be carried by holdfast fittings carried into the wall. The simplest and most cost-effective door can be made of vertical planks held together with horizontal or diagonal battens.
The simplest frameless window consists of a vertical plank (9” wide) set into two holes, one at the top and one at the bottom. This forms a simple pivotal window. Wide span windows can be partially framed and fixed to walls or can have rows of pivotal planks.
