Frequently Asked Questions
What type of loft conversion is cheapest?
A dormer conversion is typically the most affordable option at £40,000-£55,000. Velux (rooflight) conversions can be cheaper but offer less headroom. Mansard conversions are the most expensive but add the most space.
Does a loft conversion add value to my house?
A loft conversion typically adds 15-20% to a property's value in London. This makes it one of the best returns on investment for home improvements, often paying for itself through increased property value.
