Loft Conversions

Specialists in Cambridge loft conversions. Add an extra bedroom, a home office or an entertainment room to your property with a loft conversion that takes advantage of currently unused roof space.

A loft conversion is a relatively affordable way to extend your property without significant structural changes and, in some cases, doesn’t require planning permission.

At Fenlake, we can deliver all types of loft conversions in Cambridge, however, the most popular types include:

  • Dormer – Most popular type of loft conversion that protrudes from the roof in a box shape. It is the simplest conversion type as it requires few structural changes. You'll be left with a cube-like interior finish.
  • Mansard – Constructed by raising your property's Party Wall (requires planning permission). You will be left with a flat roof extension with slightly sloping walls.
  • Hip to gable – Perfect for end of terrace and detaches properties. This conversion straightens one end of the roof to form a wall, creating a large interior space.
  • Roof light – This requires no changes to the loft itself and consists of adding roof lights (windows) and reinforcing the floor to make the loft useable.

As well as converting your loft, we can ensure you’re left with a fully-functioning conversion by adding a permanent staircase and altering your landing as required.

Getting started

Many homeowners make the mistake of planning a loft conversion without fully understanding how much useable space is available. That’s why all our projects start with an on-site survey, where we inspect your loft and can advise you on the best way to use the space available based on your needs. This is one of many reasons we're one of the leading providers of loft conversion in Cambridge.

For example, you may think you have enough space for a large, open-plan office, only to realise that you can only have a Mansard loft conversion, which will leave you with sloping walls and a less efficient space. Similarly, you may think your loft only has enough room for a small bedroom to realise there’s space for a double bedroom and an en-suite. That’s where we can help.

During your consultation, your builder will provide a full quote that details the necessary work. We’ll then give you some time to decide and can proceed once you’ve signed off on the build.

Throughout your conversion, your Project Manager will keep you up-to-date to ensure we’re working to time. Rest assured that most loft conversions can be completed in 3-4 weeks.
