Loft Conversions

Loft Conversions

Here at JMA Lofts Ltd, we undertake all types of loft conversions. Choosing which one is right for you will mainly depend on 3 factors.
  1. How you would like to use your loft space
  2. The feasibility of your requirements
  3. Your budget.

The following information will further explain the 3 most popular types of loft conversions available.

Velux/Roof light Conversions

Velux are the leading manufacturer of roof windows and with over 60 years experience producing windows the name Velux has become synonymous with this type of conversion. This type of conversion is generally very cost effective and does not normally need planning permission.

Velux windows are installed to fit flush with the line of the roof and leave the vast majority of the existing roof structure untouched. As they do not require extensive alterations to the roof this option helps keep the cost of the conversion down. As the loft is not extended beyond the original roof line planning permission is not normally required.

A Velux type loft conversion works very well for lofts where there is a good amount of headroom or if there are constraints on planning, for example if you live in a conservation area. Velux roof lights can be fitted quickly and easily meaning there is minimal disruption or delays due to bad weather.

Dormer Window Conversions

A dormer is an extension to the existing roof, allowing for additional floor space and headroom within the loft conversion. Dormers protrude from the roof slope, normally at the rear of the property and can be built in a variety of styles. Internally, a dormer will have a horizontal ceiling and vertical walls compared to the normal diagonal sides of a conversion. In lofts that have limited space or headroom a dormer will provide additional space that can help make a conversion feasible.

Flat roof dormers tend to give the maximum amount of additional internal space. Gable fronted and hipped roof dormers have much more of an aesthetically pleasing presence, however, unless the headroom internally is substantial, they often will not give as much space as a flat roof dormer would, and will cost more to build due the extra complexity.

Hip to Gable Conversions

A hip to gable conversion involves making fairly major changes to the roof. The gable wall is built up to the ridge line and a new section of roof is built to fill in the gap. As a general rule, houses with hip roofs tend to not have enough internal volume for a conversion to be practical so a hip to gable conversion is the best solution.

A new gable wall will be built either in masonry or timber. There are several options for the finishing of the masonry gable wall, a few of which include brickwork, blockwork and render. If the gable wall is built from timber they are normally finished in render or tiled. Usually in both cases, JMA Lofts try to match external materials as close to those that are existing. As a hip to gable conversion changes the outline of the roof, planning permission will be required unless the proposed conversion falls within your permitted development allowance. Once the roof has been extended the conversion is normally completed with either Velux roof lights or a dormer.

As most loft conversions fall under permitted development rights, planning permission isn’t usually required, as long as the conversion follows certain guidelines, however, building regulations approval will always need to be obtained, JMA Lofts can take care of all this for you.

Project Management

Project Management

Project management is an important service provided by JMA Lofts. It not only helps to make sure that schedule end dates are met, but it also enables us to adapt to any possible alterations whilst works are in progress, more importantly keeping our clients informed of every aspect at all times, whether that be through weekly meetings, telephone, or email.

Once our quotation has been accepted and your vision is ready to be realised, JMA Lofts promise to deliver a dedicated project management service throughout the build.  All conversions are managed by the company Director, Justin Allen, who will arrange weekly meetings on-site to talk through various stages and answer any questions you may have as the project moves forward.

– Quality And Service Conscious! –



Included as part of every JMA Lofts conversion is a 1 year free maintenance service and an 8 year structural guarantee.

1 Year Free Maintenance Service

To give peace of mind to our customers, we have an aftercare package to ensure that, once the loft conversion is complete, we leave open a point of contact for 1 year, to correct any teething issues, and of course, this service is free of any charge. The main areas of maintenance are as follows:

  • Making good any cracks that may appear in plaster works due to settlement of the structure.
  • Taking up doors which have expanded during the year due variation in room temperature.
  • bleeding of radiators.
  • squeaks in floorboards that have occurred due to settlement of the structure.

The above mentioned are just a few that are covered.

Although we do our up-most to keep any potential maintenance to a minimum, it’s inevitable that some of our conversions will require it, purely down to what’s structurally involved. That’s why implementing this service is important to us, to give you peace of mind.

8 Year Structural Guarantee

As well as providing a free maintenance service for the first year post completion, JMA Lofts also back that up with an 8 year structural guarantee on the materials used and the workmanship carried out during the conversion. This will ensure that you’ll have complete peace of mind, and that you can relax and enjoy your new living space knowing that we are just a phone call away in the unlikely event that you will require our attention. Our dedication to you is important to us.
