Does Loft Conversions London have an accreditation?

Our company has accredited specialists in loft conversion. We rigorously assess all accreditations.

Every kind of loft conversion needs to expand the room space. Many small attic spaces need special loft conversion to extend the headroom. Dormer is one conversion that adds headroom. If that is not possible then we will go for Hip-to-Gable which adds more height to a roofline.

A well-planned, designed and implemented loft conversion adds up to 20% to a property’s value.

Your property basically determines the loft conversion type you should go for! We will also consider your budget.

The simplest is a loft space opening providing support for the new structure using new steel beams and adding Velux windows in the roof. This is only possible if there is high ridge that gives plenty of space for creation of rooms without using a Dormer.

Most homeowners prefer the addition of a minimum of one Dormer in the loft conversion. It can be either pitched- or flat-roofed dormer. The Hip-to-Gable there is no need to worry as we will suggest the best one for your home.

On average, the shortest time would be 4 weeks to 8 weeks depending on the complexity of the project. Here are the average times for a few loft conversion types:

Dormer- 5 weeks

Roof light- 4 weeks

You may be able to build a loft conversion under permitted developments but with a listed building or property in some designated areas, the laws will be different. We will ensure that you know what is permissible.
