Types of Loft Conversion


  • Velux
  • Dormer
  • Hip to Gable
  • Mansard

Velux Conversion


A Velux conversion is where the proposed new room is situated wholly within the existing roof void. Velux loft conversions can be the most cost effective way of converting your loft space into a habitable room.

Installing ‘Velux’ windows provide the light and ventilation requirements. We only use Velux windows as they are, in our opinion, the best on the market. They come in a wide range of shapes and sizes and have a comprehensive range of extras. They can be installed in groups horizontally, vertically or both to create a stunning feature within the room.

Dormer Loft Conversion


The most common loft conversion, and by far the best way of maximising the space you have in your loft, is to install a dormer window. The sloping section of a roof elevation is removed and a studwork dormer is built around the opening, transforming the sloping area into one that has full height headroom. The dormer window then allows light to flood into the new room. It is sometimes possible, subject to planning permission, to install a Juliet balcony in a rear dormer to provide further natural lighting.

The dormer is then capped with a flat roof and weathered with high performance mineralised felt or similar.These types of roof dormers are usually built off the external walls so they mimic the area of the room below.

To satisfy Town & Country Planning Permitted development requirements, most dormer conversions are tile clad to match existing roof elevations.

Hip to Gable Loft Conversion


If your roof has pitched elevations to three or more sides it is possible to remove the side or rear section of roof and transform it into a gable end. This allows you full height headroom right to the side or rear of the property. If this roof conversion is linked with a flat roof dormer the resultant floor area is eminently usable as a large playroom, a master bedroom with en-suite, or multiple bedrooms.

Mansard Loft Conversion

A mansard roof has two slopes, the lower slope is close to vertical at 72 degrees and the top section of the roof is almost horizontal. A mansard roof has the advantage of maximising the available space within your loft.

Mansards are commonly built by raising the party/gable walls either side of your house to make the profile for the mansard and then creating the timber frame. A mansard loft conversion will almost certainly require planning permission.

Helpful Advice


Planning permission is not necessary for all conversions.

We would always obtain a certificate of Lawful Development for those projects that don’t require Planning Approval.

All loft conversions require Building Regulation Approval.

Loft Conversions are one of the best ways of adding value to your property.

A conversion only adds value to your property if it has all the necessary Approvals including Electrical certification, Building Reg etc…

We endeavor to limit the noise and disruption to your household as much as is possible. Access to the work will proceed via the scaffolding. Only when it is absolutely necessary do we work inside you home. This coincides with the installation of the staircase usually occurring towards the end of the project.

Bathrooms and en-suite facilities can usually be built into loft areas. However this is very much dependent on the positioning of the existing services, i.e. Soil pipe, hot and cold feeds, the water supply, positioning of existing water storage vessels, boiler suitability etc…. This can all be assessed during the initial site survey.

Not all loft spaces lend themselves to conversion, however a phone call and a site visit will tell you for sure.

It may be that an extension could provide the additional space you require.

Whichever the option, going up or going out, our experienced surveyors can advise you of your properties potential.
