💬 Questions about hiring a builder in Barnes
Do I need planning permission in Barnes?
Many rear extensions and loft conversions fall under permitted development, so they don't need full planning permission. Rules are stricter in conservation areas and for flats. Check with the council or ask builders when they quote.
How many quotes should I get?
Three is a good number for building work. It gives you a sense of the fair price and lets you compare how each builder plans the job, not just the total.
What should a builder's quote include?
A written breakdown of labour and materials, a start date and timeline, a payment schedule tied to stages of work, and who is responsible for skips, waste and making good.
