Can I undertake a Velux loft conversion myself?
We do not advise DIY Velux loft conversion. The design process is especially tricky. You have to ensure that the building is strong enough to support the loft conversion and the design maximises space in the loft whilst sticking to Brighton building regulations. A poor design could endanger the lives of your family and those around you.
If you build a loft without getting the right permit, your loft is illegal and it loses any assumed increase in value. This makes it very difficult to sell your home when you want to move.
