  • Design & Planning

    The team at Create-Room can originate full working drawings and structural calculations for your proposed loft conversion.

    We will demonstrate our experience when preparing your plans. They will be originated to provide you the maximum space achievable while being considerate to the existing property. We will consider all relevant approvals required so that they are considered in the design of your loft.

    Loft design is specialised and many draughtsman do not consider ambiguous elements such as creating adequate head height, the positioning of staircases and structural steel formation when designing the loft layout. We have the experience so that we do consider these factors.

    We have numerous lofts that we have previously converted for you to look at. This may help when deciding on a final design for your loft conversion.


    SURVEY

    An appointment will be made and one of our experienced Surveyors will visit your property. Accurate measurements & dimensions of the existing dwelling are recorded and photographic evidence of your existing property will be taken.

    This will enable us to be sympathetic with the existing property when designing your proposed conversion. Preliminary drawings will then be originated in accordance with your specific requirements.


    CUSTOMER APPROVAL

    The preliminary drawings will be presented to you for your approval. Any amendments in the design or layout can be made at this point.

    Once you are happy with the plans, Full working plans will be originated incorporating a structural layout. Full, working structural calculations will be originated.

  • Building Regulations

    Building Regulation Approval

    All loft conversions need Building Regulation Approval. Either you’re Local Authority or an Independent Building Control Company would be appointed.

    Full plans and structural calculations will be submitted to the chosen Building Control authority. These, in turn with onsite, visual inspections will ensure that the proposed design and work is sufficient to meet their requirements.

    Once they are satisfied that your loft conversion meets the set Building Control Regulations, a completion letter will be forwarded to you.


    Permitted Development Allowance

    A loft conversion for your house is considered to be permitted development, not requiring an application for planning permission. This is because the effect of such developments on neighbours or the surrounding environment is likely to be small.

    The permitted development allowances described here apply to houses and bungalows, not flats, maisonettes or other buildings.

    If you are unsure, your Local Authority will be able to confirm if your permitted development rights have been removed from your property

    The following conditions and limits must be met to ensure your proposed loft conversion complies with Permitted Development:


    ADDITIONAL VOLUME LIMITS

    Any additional roof space must not exceed these volume allowances:

    – Terraced Houses & Bungalows 40 cubic meters
    – Detatched Houses & Bungalows 50 Cubic meters
    – Semi-detached Houses & Bungalows50 Cubic meters

    Please bear in mind that any previous roof space additions must be included within this volume allowance. Although you may have not created the additional space, a previous owner may have done so.


    DESIGNATED LAND

    Roof extensions are not permitted if your property is within a conservation area.


    FRONTING HIGHWAY

    An extension beyond the plain of the existing roof slope of the principal elevation that fronts a highway is not permitted development.


    MATERIALS

    Materials to be similar in appearance to the existing house.


    HEIGHT LIMIT

    No part of the extension to be higher than the highest part of the existing roof.


    BALCONIES

    Balconies, verandas or raised platforms are not permitted development.


    WINDOWS

    Any side facing window must be obscured glazed and non-opening unless the parts which can be opened are more than 1.7 meters above the floor of the room in which it is installed.


    DISTANCE FROM EAVES

    Roof extensions, apart from hip to gable ones, to be set back, as far as is practicable, at least 20cm from the eaves.

    The 20cm distance is measured along the roof plane.


    PROTECTIVES SPECIES

    Work on a loft or any roof may affect bats. You need to consider protective species when planning work of this type.


    Certificate of Lawful Use

    If you want to be certain that your property does not require planning permission, an application for a lawful development certificate can be applied for at your local authority.

    It is not compulsory to apply for a Lawful Development Certificate but you may be required to produce one at a later stage for example when selling your property.

    This certificate will confirm that your loft has been converted using your Permitted Development Allowance.
    Planning Permission

    Should your proposed loft conversion not be permitted under Permitted Development and a Certificate of Lawful Use be refused, a Planning Permission Application would need to be submitted to your Local Authority. It is their responsibility to decide whether a proposed development should go ahead. Planning permission takes approx. 8 weeks from the date the validate your application. We will consult with the Planning Officer appointed to your application to check the progress of it and act accordingly should it be visible.
    Party Wall Agreement

    Walls shared by adjacent properties are usually jointly owned by the two owners and are termed party walls.

    The party wall act provides a framework for preventing and resolving disputes in relation to party walls.
    If you intend to carry out any work to the party wall, it is your duty to inform your neighbouring property of your intentions. This should be done in writing before work commences.

    The 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.

    An adjoining Owner cannot stop someone from exercising the rights given to them by the Act, but may be able to influence haw and at what times work is to be done.

    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.

    We can recommend a Party Wall Surveyor should it be required.
