  • What size of an extension can I build under Permitted Development?

    Permitted development guidelines for the house extension size can vary based on the type of property you are extending. As a general estimate is that 3m is allowed for a terraced and semi-detached properties. Detached properties can get up to 4m without planning permission.

  • When do you need planning permission for an extension?

    You will need planning permission for an extension when the design and size of the extension exceeds the provisions of permitted development. If you live in a flat or conservation area you will need to apply for planning permission regardless of the design and size of the extension.

    Once the planning application has been submitted to the local authority, it can take up to 8 weeks. It takes between 4 to 8 weeks for an architect to prepare and submit the plans. Ideally, we suggest to give at least 3 months in advance for the construction company to start the process.

  • Will my Boiler work effectively with my new House Extension?

    By adding a house extension, the demand for current hot water and heating systems will increase. You might need to change to a new boiler that has a bigger output. Many homes tend to install a hot water cylinder when extending their property to the rear.

  • What do I need to know about the Party Wall Act?

    Your neighbours cannot stop you from constructing up to, or even on, the boundary between your properties, even if it requires access onto their land. This issue is not covered by planning or building control. If you are undertaking a house extension that involves digging or building foundations within 3m of the boundary, party wall or party wall structure, or digging foundations within 6m of a boundary, this sort of work will require you to comply with the party wall act. You will need a surveyor to act on your behalf. Such an act does not apply in Scotland.

  • What if my House Extension is near or on a Sewer?

    If your house extension will be built over or near a seer, you have to contact your local water board before work commences. In many cases, your architect will have to draw plans on how you intend to change the pipework, and these will be submitted to the water board for approval. It can take up to 3-4 weeks to get this approved and we strongly suggest not to start any work before obtaining a letter of approval.

  • Can I stay on site during the house Extension?

    Yes, it is normal to live on the site throughout the house extension, however there will be dust and mess and it can slow down the progress as the builders will try to work around your life. If you are not prepared to live with the disruption, then you should surely look for temporary accommodation especially during the dusty stage.

  • Do I need to inform building control of my house extension?

    Yes, before you commence your construction project, you will need to submit either a building notice or a full planning application to building control. A building notice will allow you to start the work quickly but there will be lack of protection that a building control has signed off on the construction work. In this case, you will be liable to correct any work that faults to meet building regulations standard upon inspection.

  • Building regulations in Edgware

    Regardless of whether planning permission is required or not, any sort, any construction project must comply with the building regulations. You need to make sure that whoever undertakes the work can self-certify the work, for example, FENSA accredited window fitters, Gas Safe engineers, NIXEIC registered electricians and so on. If these requirements are not met, you could be served notice to take the extension down and will have trouble selling your home without relevant building regulations certificates.

  • How to brief an architect before starting our project?

    Before starting your house and kitchen extension, its vital you give as much information as possible on what you want from the house extension, your timings, how and when you intend to pay them and what penalties will be in place if deadlines are missed. The architect will send you a detailed plan and a contract to sign.

  • How to get Structural engineer calculations?

    If your house extension requires any structural changes to your home, you may need a structural engineer. A structural engineer can provide the technical drawings and calculations which can be used to get building regulation approval. This will also be used by the construction company during the house extension work.
