Frequently Asked Questions
How long does a loft conversion take?
A Velux rooflight conversion typically takes 4-6 weeks on site, a dormer conversion runs to 6-8 weeks, and hip-to-gable conversions usually take 8-12 weeks. The design, planning, and building regulations process adds time on top of that, which we'll walk you through before any work begins on the roof.
Are you based in Northamptonshire?
Yes. Heritage Build Group is based in Kettering, in the heart of Northamptonshire, and we build loft conversions for homeowners right across the county.
What types of loft conversion do you build?
We build Velux rooflight conversions, dormers, and hip-to-gable conversions. The right type for your home depends on the existing roof shape, the head height you've got to work with, and whether the property is in a conservation area or has any planning restrictions on the roofline.
