Loft conversions in London are growing in popularity as residential space is becoming more and more in demand.


Initially, you’ll need to decide whether your loft is suitable for conversion by considering similar properties, your available head height, your roof type, and the floor below. Looking for similar properties with conversions on your street will give you an idea of whether this will be a possibility for your home. This should be the first step as it will often confirm whether your plans are doable.

Following this, you’ll need to measure the tallest part of your loft. The minimum required height for a loft conversion is 2.2 metres. If your head height exceeds this, you’ll likely be able to go ahead with your conversion.

As well as height, it’s important to determine whether your roof is made up of rafters or trusses. Rafters run along the edge of the roof and leave hollow, triangular space; this is the most ideal roofing for loft conversions. On the other hand, trusses run through the cross-section of the loft. Though converting a loft with trusses is doable, it will require extra structural support and incur extra cost.

Finally, you’ll need to think about the floor below the loft as you’ll need to assess staircase placement. Staircases need to be accessible and will often occupy a large chunk of the room, so this needs to be considered prior to any conversion.


The time that your loft conversion will take is dependent on the conversion type and the loft space itself. Typically, a conversion will take anywhere from four to eight weeks to complete, with the first week being used to gather materials and prepare your home. Work will usually commence on your property’s exterior before dealing with the stud walls, insulation, and flooring on the inside. Plumbing, electrics, and plastering will mark the end of the conversion project.


We deal with all major types of loft conversions including mansard, hip-to-gable, dormer, and Velux loft conversions in London.

A mansard loft conversion runs across the length of your roof and makes the slope almost vertical. This will gift your property with lots of extra space and is suitable for most property types.

A hip-to-gable loft conversion extends the sloping “hip” roof outwards at your property’s side to create a vertical “gable” wall. This will allow for more internal loft space but will only work on detached or semi-detached properties.

A dormer loft conversion involves an extension protruding from the roof’s slope and is the most popular form of conversion. Their popularity stems from their adaptability to any home with a sloping roof.

A Velux loft conversion is the development of a new room within your existing loft space. Usually, the roof’s profile is not altered in this process and it’s particularly popular in the London area to create extra living space.


If you own a London property, maximising the space you have available increases its value for when you come to either rent out or sell your house. Despite its benefits to property value, converting your loft can feel like a daunting and complicated process.
