Choices to weigh up in Kenilworth

Mansard conversion

The rear roof slope is rebuilt almost vertically, at around 70 degrees, with a flat top and windows set into it. It gives the most space but changes the roof shape significantly, so it normally needs a planning application. It can suit terraces where a dormer would be too limited, and it's the most expensive of the common types.

Rear dormer conversion

A box-shaped extension built out from the rear roof slope, with vertical walls and a flat roof, giving full standing height across most of the room. It suits semis and terraces because it adds the most usable space for the money. Under permitted development it must be set back from the eaves and stay within the volume allowance.

How much should you budget in Kenilworth?

Expect to budget between £22,000 and £72,000 depending on size and specification in Kenilworth. A rear dormer with a double bedroom and shower room on a three-bed semi: typically £42,000–£52,000.

Loft conversions in Kenilworth: common questions

How long does a loft conversion take?

Most take 6–10 weeks on site, with roof-light conversions at the shorter end and hip-to-gable or mansard work at the longer end. Allow time beforehand for drawings, a lawful development certificate or planning decision, and party wall notices, which need two months on a semi or terrace. We plan the start date around those periods so nothing is left waiting.
