House extension plans: stunning open-plan kitchen/diner

Whether you are looking to open up the ground floor of your home to create a stunning open-plan kitchen/diner or looking to add space upstairs with the addition of a couple of bedrooms we can create your dream happinest.

With the relaxation of permitted development laws, many house extensions can be built without the requirement of Planning Permission. However, you are in most cases required to have Architectural extension plans produced for building control approval. 

Our friendly team of local happinest planning consultants are ready to advise you as to what permissions your project may or may not require.

    FAQ's
    Whether you will need planning permission depends upon the size and type of your extension, if you are in a conservation area, article 4 area or the property is a listed building.

    Permitted development rules have recently been relaxed, giving you the ability to build an extension to up to six metres in some circumstances.
    1. List all requirements for your extension. Additional bedrooms, bathrooms, new kitchen, larger bathrooms and more storage space.
    2. Contact a reputable Architectural Practice that offer a FREE home visit to discuss your project.
    3. Have your architectural drawings prepared for either planning or Permitted Development.
    4. If required, ensure your architectural practice will manage the entire planning process for you.
    5. Have your Building Regulation Drawings prepared so that you can get accurate quotes from builders.
    6. Ensure your architect will submit and deal with your building control application for you.

    It usually takes 8 weeks from the time of submission for a the local authority to approve the development. If your project falls within Permitted development rights the process can be much quicker.

    The plan we create will be comprehensive, considering the opinions of people in the community and the aptitude of the design as well as much more. Although not always possible, we will aim to receive a planning permit on the first attempt. If the planning permit was not obtained, usually just minor changes are required. We will communicate with you throughout the process so that you are kept informed.
