A.
a) 4 general principles of window design.

Proportion or Scale - Windows should exhibit a vertical emphasis to complement traditional styles. Where they include casements or glazing bars these should be symmetrically arranged. If wider windows are required, multiples of the basic unit should be considered.

Functionality - Windows should be positioned on stone, slate or concrete cills. The window should be set back from the outside wall - (this is called the reveal) usually to a depth of 100 mm (4”). This will shelter the opening from rain. Windows using only the modern integral cill positioned flush with the outside wall look less solid and “stuck on” and should be avoided.
Colour and attractiveness - Windows have traditionally been painted white to reflect light inside and contrast (from the outside) with the dark window panes. In order to maintain this tradition it is preferable for windows to be finished in white and not stained or varnished.

Usability and Maintenance - In existing buildings, where ever possible, windows should be repaired rather than replaced. If windows have to be replaced they should match the materials and proportions of the windows already there. The following show examples of good proportions which appropriately reflect traditional window styles in Ceredigion. The simpler less cluttered forms generally look better.
