Above-it-All is expert in the preparation of architectural loft plans.

Most loft conversions and some dormer conversions do not require Planning Permission

However a loft for habitable use does require Building Regulations Approval (pass BCO inspection). For this, building plans are needed for Building Control Officer inspection which specify what and where work is planned. The Building Control Officer inspects not only plans but the work at stages of development according to these plans, and then passed the work if it conforms to standards.

Usually, only lofts that require significant structural alteration, are within conservation areas, or have dormer windows require Planning Permission.

If you are unsure about your loft, call us for more information.

What should I do if I require floor plans?

Lofts are subject to complex and changing regulation, so you need a company with experience in loft planning. This will save you time and expense because they should pass first inspection.

An architect or surveyor surveys and measures the relevant areas of your home and loft, and then specifies in detail the loft construction work and materials required within the document (known also as building plans or floor plans).

  • If Planning Permission is not required then they are inspected and passed by the BCO - Building Control Officer.
  • If Planning Permission is required then architect/building plans are submitted to the Local Authority for planning and BCO approval.

All plans passed by your Local Building Control Office conform to current UK Building Regulations

To add maximum value to a property conversion need to have been correctly planned, built and passed.

Certification of the conversion assures a potential buyer that the construction is to high standards and has been planned to cover problems regarding weight, materials and safety.

We have a specialist loft planning service for survey, design, architectural floor plans and submission to Local Authorities for buildings approval.

Our experience in drawing up architectural building plans allows us to offer a professional loft planning service throughout the Northwest.

What Are Floor Plans

Floor plans, (architectural / building plans), are a series plan drawings and elevations that show the layout of the loft.

How the loft conversion is constructed is detailed in line drawings that illustrate the current and proposed loft layout.

The final plan which gets submitted for planning permission and building regulations approval will be an amalgam of your loft ideas, our design experience and physical, cost and planning constraints.

Floor plans show walls, ceiling, heights, widths and pitch of roof; they are drawn to scale using Computer Aided Design (CAD) software.
