Planning a house extension in Redhill
An extension should solve a particular problem: a cramped kitchen, missing workspace or a layout that no longer works for your household. Decide how you want to use the space before comparing designs.
Build a clear brief
Record your preferred layout, essential features and items you can compromise on. Include a realistic budget allowance for design, professional advice, approvals and unexpected work, as well as construction.
Check permissions before committing
Planning permission and building regulations are separate considerations. Whether permission is required depends on the property and proposal; restrictions can affect some homes. Check the current position with Reigate & Banstead Borough Council and obtain appropriate professional advice before starting work. Boundary and party-wall questions may also require specialist advice.
Redhill access and site arrangements
Ask how materials will reach the property and where scaffolding, skips and equipment will go. Agree working hours, how neighbours will be kept informed and how your home will be protected from dust and weather.
Questions for an extension contractor
Ask for examples of comparable work and confirm who will supervise your project. Request a programme with stages and explain how you want design changes to be recorded.
- Who is responsible for structural design and inspections?
- What does the price include, and what remains provisional?
- How are unforeseen conditions and variations priced?
- When are payments due, and what work must be complete at each stage?
- What documents and warranties will be handed over?
