Things to consider while selecting a builder -

Selecting a builder can be tricky, with significant repercussions, as Structure and remodelling is not something we do typically. If it has done wrong, it can result worse. Avoid a few common mistakes while selecting one.

  • While selecting - Choose someone who has experience in extensions and restorations for your refurbishing work, or if you are developing a brand-new house, speak to someone who is experienced in brand-new homes. It is very casual for new contractors to present competitive quotes for extension and remodelling jobs, as they do have the experience to prepare a quote effectively and practically, which will later be a trouble for you. Going for the lowest bid might not always be the best move. Get an affordable proposal offer to serve you with the ultimate value for your money.
  • Check with Previous Clients of that Contractor - Check with the contractor's reference, and get a sharp picture of their reliability. Have a look at various contractors' work, including house extension Gerrards cross, to vouch for them.
  • Do not Sign on any Incomplete Paperwork - Always have a work scope in writing. You need to get the detailed quotations, including insurance, approvals, construction work agreement handy to avoid any future uncertainty. Also, don't rush to sign any incomplete work paper.
  • Have detailed specifications - Have a complete project specification list, when you are heading out to get a home remodelling contractor. It will permit you to have a clear focus on your project, and you can also compare it with others.

What is building control and its requirement for my project?

Building control is how Local Authorities enforce compliance with current Building Regulations. There are two ways to get the certification and advice for your project. Either you can go to the Local Council’s Building Control Department or can appoint an approved authorized inspector to carry out the inspection and certification on behalf of the local authority. They verify that your project meets all current Building Regulations or not. They review all works such as drawings, the actual work, and once the project is completed, they ensure that it will meet all the described criteria. After that, they issue the final compliance certificate.

Our experience with the private inspectors helps to speed up the process, and as we are already aware of most of the norms, we eliminate all chances of rejection. You can leave this aspect of your project entirely on us.

  • 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.

  • How long does planning permission take for a house 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 Gerrards Cross

    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.
