Loft conversions are an increasingly popular option for home-owners looking to increase the available space in their homes, and can be one of the most cost-effective ways of extending a property.



A&R Design have over 40 years’ combined experience in this area, and can help you ensure that your property is suitable for a loft extension, guide you through the different decisions that need to be made, and carry out the whole project from start to finish. Our expertise means that you can be confident that our work will meet all relevant building regulations, and that the finished loft conversion will make the best possible use of the available space, to become an attractive and useful addition to your property.

We will of course be happy to talk you through all the relevant aspects of your loft conversion project.

This article covers some of the key areas to consider if you are thinking about a loft conversion. Next month we will cover other important considerations including windows, bathrooms, storage and finishing touches.


When assessing the viability of a loft conversion, you will need to start by considering whether you will have adequate space. The most important things to think about are:

· Is the height within your existing roof sufficient to provide a high enough ceiling in your new room? As a general rule of thumb, the space should be at least 2.2. metres high, so that the finished ceiling height of the room will be at least 2 metres.

· Will your finished room have a sufficiently large useable floor space for your purposes? You will need to take into account the fact that the slope of the roof will mean some loss of useable space at the sides of the room (although you may be able to use some of this for storage).

It is usually possible to get additional space by using a ‘dormer’ extension, which is an extension that protrudes from the existing roof line. Careful design of the room can also help with maximising space.

As part of our service, we will carry out a comprehensive feasibility survey to ensure that the space is suitable, including having adequate ceiling height and floor space to provide a comfortably usable room.

Planning / Permitted development

It is important to establish at the outset whether planning regulations will allow you to have a loft conversion. In some cases this may not be possible – for example, if you live in a conservation area or in a listed building – and you may have to look at alternative options.

Where a loft conversion is permitted, there may be other restrictions in place affecting issues such as the size of the permitted additional roof space, whether an extension goes beyond the plane of the roof, the types of materials to be used (to ensure some degree of consistency with the rest of the house), whether or not you can have any kind of balcony and the types of windows you are allowed.

A & R Design have extensive experience in working with planning regulations, and can help guide you through the process, and look at the different alternatives if your original plans are likely to cause a problem.


For almost everyone, budget will be a significant factor in deciding on the viability of a loft conversion project, and it is important to think about all the different aspects of the project which will contribute to the cost – from providing access to your new room(s), to installing plumbing, lighting, heating and windows.
