Different types of loft conversion and cost to implement it in UK?

Types of loft conversion

Loft conversions are very popular across the UK, and for good reason! They’re affordable, achievable and can transform the functionality of your home. As many homeowners seek to maximize the potential of their properties, North London builders are seeing more and more loft conversions.

Let’s not waste time with unnecessary talk. The two big questions we’re addressing here are:

  1. What’s are the different types of loft conversions?
  2. How much does a loft conversion cost?


There are three basic types of loft conversions. Of course, each has its pros and cons and the one you choose is likely to be influenced by the age and structure of your home and the size of your purse!

  • Roof Light Loft Conversion

If your loft already has enough available space and headroom, this is by far the easiest, least disruptive, and cheapest option because it doesn’t require any change to the existing roofline. A roof light conversion (or Velux loft conversion as they are sometimes known) simply involves putting windows into the existing roof structure, strengthening the floor, and installing a staircase. This solution is a great one for properties where there are planning constraints.

Different types of loft conversions
  • Dormer Loft Conversion

A dormer extension is one that protrudes vertically from the side of a sloping roof, adding extra floor and headspace within the home. Dormer conversions are among the most popular type of loft conversions because they are suitable for both the back and or the front of the home and can be added to pretty much any sloped roof.

A dormer conversion is a great way to maximize space: 90° walls and a horizontal ceiling which improves functionality and usability. And due to its flexibility, it’s well suited to a huge range of properties including detached, semi-detached and terraced homes.

Dormer conversions come in a range of styles, depending on your needs and the size and layout of your home. They can be constructed as a full width conversion, a single dormer, an L-shaped dormer or a side dormer.

  • Mansard Roof Loft Conversion

The mansard conversion requires removing a good portion of the original roof and building walls on top of the existing roof edge at a pitch of around 70° (as opposed to the 90° walls of the dormer conversion). A nearly flat roof is then constructed over the extension, creating sufficient volume within the roof for an extra storey.

The Mansard roof loft conversion is often more aesthetically appealing than the dormer style, however, because of the amount of work involved, it is generally the most costly option and will involve planning permission.


As we say, how long is a piece of string? Unfortunately, there’s no one-size-fits-all price, but loft conversions can be achieved for as little as £1700/sqm. However, the cost of your loft conversion will be dictated by the extent of the works involved, your taste and the size of your budget, so an indicative price range is somewhere from £1700 to £2000/sqm.
