Elements such as:

1. Adequate head height
2. Positioning of staircases
3. Windows
4. Structural steel formation
5. Roofing
6. Shower rooms

Will all be considered.

The preliminary drawings will be sent to you for approval and any amendments in design or layout can be made at this point.
Once you are happy, full working plans will be created incorporating a structural layout. Full working structural calculations will also be provided.

Our team also looks at the permissions you require and advises in this regard.


Building Regulation Approval

All loft conversions need Building Regulation Approval. Either you’re Local Authority or an Independently approved  Building Control Company can 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 after their final visit your loft conversion meets the current  Building Control Regulations, a completion certificate  will be forwarded to you directly from them.

Permitted Development Allowance

A loft conversion for your house is considered to be permitted development, not requiring an

A loft conversion  is considered to fall under the  permitted development heading where an application for full planning permission is not required.

The permitted development allowances described here applies  to houses and bungalows, not flats, maisonettes.

If you are unsure, your Local Authority will be able to confirm if your permitted development rights have been removed from your property, however Lords loft will always apply to your local authority  for a certificate of Lawful development.

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 Detached 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.

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

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

Materials to be similar in appearance to the existing house.

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

Balconies, verandas or raised platforms are not permitted development.

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.

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.

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. We will always receive this prior to work commencing

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 how and at what times work is to be done.

It is essential that you discuss your plans with your neighbour prior to starting work. You may find that they have no objections and will agree to sign an informal Party wall agreement  even if they are not 100% supportive of your decision, they will no doubt appreciate being asked and consulted. If your neighbours insist on a full party wall agreement then we have  surveyors who work with us closely and the fore can recommend  Party Wall Surveyor's to you  should it be required. Lords loft will fully assist and guide you through this process
