CHECKLIST EXTENSION

The essentials to consider if you’re thinking about a glass extension

NOTIFY NEIGHBOURS If you’re building right up to a boundary wall, you’ll need a party wall agreement and written consent from your neighbours. If they decide to object or don’t reply, you will require a surveyor to oversee the process, to ensure you’re not damaging any neighbouring property. These rules are even less generous if you’re in a conservation area or live in a listed property, and you may require extra consent.

HIRE AN ARCHITECT Use the services of an architect on a major build to provide design inspiration, plan the space, draw up accurate plans and ensure the project is compliant with planning rules.

MANAGE THE BUILD Decide who will manage your build. Any home renovation TV show highlights the cons where this is missed – it never ends well for the budget! Whether you’ve used an architect or designed the extension yourself, you’ll need a main contractor or a project manager to keep the build on track.

ASSESS THE BUDGET THOROUGHLY

Be clear on setting the budget and allow an extra 20% for unforeseen expenses that may occur. Ensure final designs, costings and payment schedules are agreed before work begins. Prioritise your money by spending on structural elements that will add a sense of space – large windows, bifold doors and roof windows are worth it.
