What does it cost to build loft conversions and extensions? It depends upon the type of conversion chosen. Generally, projects that can be completed with no structural changes to the roof cost the least. The Velux conversion is an example of this type of project. Conversions that involve significant alterations to the roof and include high-grade enhancements cost more. Get a loft conversion quote.



Among options for London loft conversions, the dormer conversion is the most popular. This project consists of an extension of the existing roof. The extension projects vertically and results in more floor space and headroom. A horizontal ceiling caps the extension inside. These conversions work well on many styles of homes, including detached houses, semi-detached houses, terraced, and end-of-terrace homes.


This type of extension originated with French architect Francois Mansard in the 1600s. In this design, the roof is flat, and the back wall slopes inwardly at an angle of 72 degrees. It is typically built at the rear of the house. Mansard loft conversion result in significant changes to the roof shape and structure, and as such, usually require planning permissions.


Also called a rooflight or skylight conversion, the Velux loft conversion is one of the most affordable extension options because no alterations are made to the roof. This also means that generally, no planning permissions are required. The main feature in this build is the addition of large windows installed flush with the roofline. Velux is a popular window manufacturer.


Hipped roofs, with their sloping sides, have limited useable space directly beneath them. Rebuilding a slanted hipped roof to one with flat-end gables opens the loft/attic area. This type of conversion changes the profile of the roof, so planning permissions are almost always required. A hip to gable loft conversion produces satisfying under-roof space and, often, enough room for a staircase. Loft conversion specialists in London such as Eloft are equipped to undertake this scale of build.
