    Sound Insulation for Extensions

    This guide explains the main points homeowners should know about sound insulation for extensions before starting a prefab extension project.

    A prefab extension is easier to plan when the technical, financial and regulatory choices are clear from the start.

    The information below summarises the practical considerations we discuss with homeowners during the early advice and design phase.

    What to check first

    Start with the intended use of the new space, the approximate dimensions and the relationship with the existing home. These choices influence structure, daylight, installations and cost.

    Local rules and site access also matter. A compact residential street, protected streetscape or weak soil can change the best technical solution.

    How prefab changes the process

    With prefab, the main elements are engineered and produced before installation. This makes the on-site phase shorter and reduces the amount of open-ended work in the garden.

    A good proposal should make scope, assumptions, exclusions and optional upgrades explicit before production starts.

    Next step

    Use the configurator for an initial direction, or request advice if you want the project checked against your home, plot and planning constraints.

    Summary

    A successful prefab extension starts with clear requirements, early technical checks and a proposal that makes scope and assumptions explicit.
