Loft Conversions - Kingston BuilderWhat to consider for your loft conversion

There are many types of loft conversions which are covered in more detail below.

The loft conversion option that may be right for your property will depend on the type of property, whether it’s a terraced, semi-detached, detached, cottage or bungalow, the size, both height and length, the interior design, and where the property is situated, for example is it on a main road and what side are any adjoining properties.

The size and height of your existing loft will also be a factor to consider when deciding, as they may mean you need to build up or out rather than just transforming the existing space available to you.

There are also some planning requirements you need to be aware of, which are covered below.

Loft Planning and Regulations

We will advise you on whether planning regulations allow you to convert your loft as planned, and suggest alternative ways to convert your loft or create additional space if they don’t. However, you may wish to note the following information when you are first thinking about a conversion.

A loft conversion will not require an application for planning permission provided that certain limits and conditions are met. These include; any additional roof space created does not exceed 40 cubic metres for terraced houses or 50 cubic metres for detached and semi-detached houses; no part of the extension exceeds the highest part of the existing roof; side facing windows are obscure glazed and non-opening, unless the parts that can be opened are more than 1.7 metres above the floor of the room in which it is installed; materials are similar in appearance to the existing house, and; roof extensions, apart from hip to gable ones, are set back, as far is practicable, at least 20 centimetres from the original eaves.

Loft conversions for houses on designated land, and verandas, balconies or raised platforms, are not permitted. Additionally the roof enlargement cannot overhang the outer face of the wall of the original house, and an extension beyond the plane of the existing roof slope of the principal elevation that fronts a highway is also not permitted.

Types of loft conversions

These are some of the most popular types of loft conversions. We are more than happy for you to contact us and say what you would like without identifying any specific type of conversion. We can discuss options, in a jargon-free way, when we have our first meeting with you.

Dormer Loft Conversion

Opens up your roof allowing you to make the most of your loft space. Suitable for all house styles, and flat or pitched roofs, they allow you to have large windows to maximise the light that reaches the loft.

Hip-ended Dormer Loft Conversion

A dormer loft conversion designed for properties with a hip-ended roofline. Their design means that stairs to the loft from your house will not intrude on or reduce your existing living space.

Cottage Dormer Loft Conversion

A dormer loft conversion specifically tailored to the design of most cottages. They open up loft space, and are usually situated at the front of the property.

Hip to Gable Loft Conversion

By creating a vertical gable end in your roof to replace a sloping or hipped roof, hip to gable loft conversions extend the useable size of your loft, making the headroom consistent throughout.

Roof-lift Conversion

Where the loft does not currently have sufficient headroom Roof-lift conversion can be the answer. By raising the ridgeline of your existing roof the height is increased and the space is opened up to a variety of uses.

Mansard Loft Conversion

With a flat roof and sloping back wall, Mansard loft conversions are usually front or rear facing. They create versatile well lit spaces, with plenty of room and with windows incorporated into the design and build.
