Permitted Development loft conversions for easy improvement.

Our planning mangers will advise you on the planning requirements for your loft conversion. In many cases, loft conversions are covered by Permitted Development (the government initiative allowing certain home improvements to be made without a planning application process). If you wish to make a conversion under Permitted Development, it’s important you stay within regulations. Our project managers will help you to design a space that makes perfect use of your roof area without straying outside guidelines.


We take care of planning permission and submit all necessary documents to building control

Our connections make planning required loft conversions easy.

If your loft conversion needs permission, our planning team will sort out all the red tape for you – from designing your conversion to fulfil building regulations and planning requirements, to getting the necessary permissions and keeping the council informed of progress. Take the headache out of your loft conversion, and make sure you get the extra living space you want, from bedroom to workspace.

Types of loft conversion

Dormer loft conversion

A dormer is a extension of the roof featured by windows, usually installed to provide more space and headroom within the loft, in addition to improved staircase access. Dormers are also popular due to the aesthetic enhancement to a property that they provide. Installation of a dormer is subject to planning permission requirements from the local authorities. It means that in some cases you don’t need to apply for planning application, only structural calculations needs to be submitted to building control.

Hip to gable conversion

In addition to roof window and dormer conversions, there are less common ‘hip to gable’ conversions, which can be installed when certain circumstances require their features.This type of loft conversion is very good option to increase useful area and volume of loft. Almost in all cases these conversions are subject to a planning permission.

Velux or roof window conversion

Roof window conversions are often an attractive option for homeowners due to their ability to fit into the line of the roof; thus not necessitating any restructuring of the roof itself. The installation of such windows will provide the loft space with substantial light. A roof window conversion in a lot of cases can be completed under permitted development rights and will not require planning permission, although they will always require building regulation approval – submission of structural calculations.

We are well established in an industry based largely on reputation, and as such make a point of employing fully vetted and highly skilled tradesmen.

We understand that having workmen in your home can be disruptive, so we aim to keep disruption to an absolute minimum and be completed to a strict timetable.
