This is the most popular type of conversion we offer. Typically located at the rear of the property this design creates a great deal of floor space. The benefits of this type of loft are forever rewarding, not only does a dormer conversion prove cost effective but it provides large amounts of space in comparison with other types of loft conversions. In most cases planning permission is not required for a Dormer loft conversion. However, we review each loft as sometimes permission may be a requirement.
A rear dormer conversion can turn a dark dingy loft into a fresh bright open space. We recommend installing Velux windows on the front roof, which sit opposite the dormer windows, this will provide the new loft space with plenty of natural light. Another popular option for rear dormers is to add French doors to the dormer face with a glass balcony for that extra special touch.

Being the easiest to build, this type of loft can be constructed quicker than any other type of loft conversion due to the existing structure of the roof staying as is, it also minimises the use of materials and is a great way to make space whilst keeping costs down. VELUX conversions always work better where there is a greater head height to use. With most cases of VELUX conversion you will not need planning permission, however we will always assess this on our site survey.
We recommend having a VELUX CABRIO®, The VELUX CABRIO® balcony opens in seconds to give your loft space a place in the sun. The innovative balcony adds air, light and a great view to your home. For added convenience, the VELUX CABRIO® balcony fits flush with the roof when closed.

This type of conversion requires extensive adjustments to your roofs structure, resulting in more vertical walls and usable space. Typically for owners with a semi or a detached house, by extending the sloping side of the roof outwards, the existing sloped roof is replaced with a vertical wall (gable) that reaches the same height as the ridge line of the roof. Whether the existing house is rendered, has brick work or pebbledash we can match the conversion to tie in perfectly with your home’s exterior.
Hip-to-Gable loft conversions usually fall under permitted development which does not require planning permission. However there are occasions when it will have to be obtained, which we will ensure is assessed during the site survey.

Pitched roof dormer conversion

A pitched roof dormer conversion is a great option when the height of the existing roof is sufficient enough to accommodate one, in some cases a flat roof dormer to the back and 2 pitched roof dormers to the front are great way of maximising space.
This type of loft conversion is one of the most aesthetically pleasing designs as it brings a huge amount of character due to all the angles it creates internally. Externally there are a number of ways you can finish your pitched roof dormer, whether it is rendered, cladded or tiled its going to look great.

An L shaped dormer loft conversion is where two dormers are built together forming, you guessed it.. an L shape. One part is built over the main part of the property and the other is built on the back elevation. Due to the shape, these dormers are usually only suitable for Edwardian and Victorian properties where this is an existing rear addition on the property.
L-shaped dormer conversions are a great option for creating more space on your property. They are the best way to extend period properties, especially if it’s a mid-terrace. This type of conversion creates so much additional floor space that it usually adds at least two large rooms to your home. Once dormer windows, French doors and Velux windows are added to the design, it creates beautifully bright, generous-sized rooms.

The exterior finish of a rear dormer conversion can either be brick, tile hung, slate hung, rendered or cladded. If your choice is to go for tile or slate, the type will be chosen on site to ensure they match the existing roof as close as possible. If the plan is to do a rendered finish, we have skilled plasterers who can create lots of different render designs to match the existing finish. If you decide on brick, the brick used will match your existing brickwork. Other external finishes such as fascias, soffits, gutters and windows will also be matched to the existing finishes — this way, the rear dormer conversion will look like it was part of the original build!

This is a brief overview of what may be required to build your loft conversion.

In most cases a loft conversion falls under the ‘Permitted development’ category, which means that planning permission will not be required. This applies to houses and bungalows but not flats, maisonettes, or other types of buildings.

Converting the loft of a house is considered to be permitted development subject to the certain limits and conditions. If these limits and conditions are not met, or Permitted Development rights have been removed in the area, then an application for Householder/Full Planning Permission will be required.

Limitations on the proposed development:

  • Materials must be similar in appearance to the existing house.
  • Volume of enlargement (including any previous enlargement) must not exceed the original roof space by more than:
    • 40 cubic metres for terraced houses; or
    • 50 cubic metres otherwise.
  • Must not exceed the height of the existing roof.
  • On the principal elevation of the house (where it fronts a highway), must not extend beyond the existing roof slope.
  • Must not include:
    • verandas, balconies* or raised platforms; or
    • installation, alteration or replacement of any chimney, flue, or ‘soil and vent pipe’.
  • Side-facing windows must be obscure-glazed; and, if opening, to be 1.7 metres above the floor of the room in which they are installed.
  • Construction must ensure that:
  1. The eaves of the original roof are maintained (or reinstated)
  2. Any enlargement is set back, so far as practicable, at least 20cm from the original eaves (see pages 35-36 of the Technical Guidance below for more details)
  3. The roof enlargement does not overhang the outer face of the wall of the original house

Certificate of lawful use

If you want to be sure that your loft conversion does not require planning permission, an application for a lawful development certificate can be applied for at your local authority. Its purpose is to certify your loft has been converted using the Permitted Development allowance. It is not compulsory to apply for a Lawful Development Certificate but you if you plan to sell the property at a later date you maybe be required to produce one.

In the event that your loft conversion does not fall under Permitted Development and a Certificate of Lawful Use is refused, planning permission will need to be obtained from your Local Authority. It is the Local Authority’s responsibility to decide whether a proposed loft conversion should go ahead. Planning permission can take approximately 8 weeks to validate from the date of your loft conversion application. If the loft conversion is likely to affect neighbours or the surrounding environment, then planning permission may be a necessity. We can advise you on this before the build begins, giving you plenty of time to apply and avoid unnecessary delays.

Party Wall Agreement

A party wall agreement is a legal agreement made between you and your neighbours, regarding any building work occurring that affects your shared wall and is for preventing disputes in relation to party walls.  If you intend to carry out any work to the party wall, it is up to you to inform your neighbouring property of your intentions. This should be done in writing before work commences.
The Party Wall Act contains no enforcement procedures for failure to serve a notice. However, if you start work without having first given notice in the proper way, adjoining owners may seek to stop your work through a court injunction. It would be advisable to discuss your plans with your neighbour first. You may find that they have no objections. Even if they are not 100% supportive of your decision, they will no doubt appreciate being asked and consulted.
If your unsure of your permitted development rights, don’t worry! Our experienced architect will obtain all the necessary documents you need to get your loft converted.
