Planning uPVC Windows Before Construction Starts

The best time to think about windows is before the walls go up. Planning openings and styles early saves compromises later.

The situation

When you plan windows before construction, you can size openings to suit the window styles you want, position them for light and ventilation, and avoid the awkward retrofits that come from finalising openings without thinking about the windows.

What to weigh

Decide rough styles and where you want large glazing, ventilation, and privacy, and share that with your architect or builder so openings are designed around them. Final measurement still happens once openings are built, but the design intent is set early.

A checklist for this

Look for this

  • Decide rough window styles per room early
  • Position openings for light and ventilation
  • Share intent with your architect/builder
  • Leave final measurement until openings are built
