  • Why do extensions cost so much?

    This is for a plaster finished shell with dormer and Velux windows and includes construction costs but not architect’s fees, which can cost around 15%. RICS says a single-storey extension with a flat roof will cost £2,360 per square metre for a nine square metre extension, with a total cost of £21,240 – before you put down flooring or install a kitchen. As you can see from the table that the larger the project, the cheaper it will be per square metre.

  • What extensions can I build without planning permissions?

    Your local authority will be able to advise you about this. Generally, you will not need planning permission for: Building an extension to the rear of the house which does not increase the original floor area of the house by more than 40 square metres and is not higher than the house.

  • How long does it take to build an extension?

    For a relatively simple, three metre, single rear extension, construction time should be around three to four months. For a larger or double height rear extension it may be more than six months.
