Full Planning and Building Control designed drawings for submission to Local Authorities.


You’ll probably need planning permission if you want to:

Build something new, make a major change to your building, e.g. building an extension or change the use of your building.

To find out if your project will need planning permission, contact your local planning authority (LPA).

Most new buildings or major changes to existing buildings or to the local environment need consent - known as planning permission.

Without a planning system everyone could construct buildings or use land in any way they wanted, no matter what effect this would have on other people who live and work in their area.

Your local planning authority is responsible for deciding whether a development - anything from an extension on a house to a new shopping centre - should go ahead.

Our work reflects an enduring commitment to sustainability and the belief that design is one of the most powerful strategic tools for securing enduring meaningful environments.

Building Control

In most cases, it will be necessary when extending a building to ensure that everything done complies with the Government's Building Regulations. Unless the planned extension is a porch, conservatory or detached garage built at ground level, taking up less than 30m2 of floor space, it's likely that Building Regulations will be relevant.

Building regulations are minimum standards for design, construction and alterations to virtually every building. The regulations are developed by the UK government and approved by Parliament.

The Building Regulations 2010 cover the construction and extension of buildings and these regulations are supported by Approved Documents. Approved Documents set out detailed practical guidance on compliance with the regulations.

Building regulations approval is different from planning permission and you might need both for your project.

You can apply to any local authority building control department or Approved Inspector for building regulations approval.

These apply to any building work in England and Wales, and set minimum standards for the design and construction of buildings to ensure that they comply with health and safety rules. They also include certain requirements involving fuel and power conservation, and ensure that access and facilities are provided for people with disabilities in public buildings.

A reputable architect/building design company will be able to help you in ensuring that your extension meets all the Building Regulations that may apply to the work, and in making sure that any inspections required are completed and work meets the construction and performance standards set by the regulations.

Building Regulations approval is a separate process from obtaining planning permission for your extension, and it is extremely important to ensure that your extension is approved in both regards. To achieve compliance with Building Regulations, you or your architect/designer must submit full and detailed plans of the proposed extension, together with the appropriate application form and fee, to your Local Planning Authority..

Building control surveyors will examine the plans to guarantee that they accord with Building Regulations, and will approve the project. Your builders are required to notify the council when building work commences and at various stages throughout the project, and inspections can be made to ensure that work, such as laying foundations, damp proofing and installing drains is carried out to standard. A final inspection will be made upon completion of the extension, and a certificate of completion will be issued if everything is up to scratch.

Information about how Building Regulations might apply to different types of extensions can be found through the Government's Planning Portal (go to:, or via your Local Authority.

Interior Design

Interior design is the art and science of enhancing the interior of a building to achieve a healthier and more aesthetically pleasing environment for the people using the space.

As interior designers we plan, research, coordinate, and manage such projects. Interior design is a multifaceted profession that includes conceptual development, space planning, site inspections, programming, research, communicating with the stakeholders of a project, construction management, and execution of the design
