💬 Questions about house extensions in Islington
Do I need planning permission in Islington?
Many rear extensions 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 long does an extension take?
A single-storey extension is often 3 to 5 months from first dig to final snag, plus time for plans and approvals. Your builder will give you a timeline.
What should the quote include?
A written breakdown of labour and materials, a start date, a payment schedule tied to stages of work, and who handles skips and waste.
