Designed for Planning-Approved Homes
At planning stage, decisions affect:
• Structural openings
• Steel placement
• Floor levels
• Sightlines
• Thermal performance
• Aesthetic finish
Getting glazing specification correct before build progresses avoids compromise later.
We regularly work with:
• Architects
• Structural engineers
• Main contractors
• Private homeowners managing their own build
Whether your project includes sliding doors, bifolds, aluminium windows or structural glazing, we provide accurate survey, specification and installation.
