How much does a full home renovation cost?
It depends on your home and what you want to change, so we talk it through with you at your design appointment. Our guide to house renovation costs explains what moves the price.
How long does a full home renovation take?
Every project is different, and timescales depend on the scope of work involved. During your design appointment, we will talk through a realistic timeline based on your specific renovation.

Arch takes responsibility for the whole job. Kitchens and bathrooms are fitted by our own installation team, the same crew for over seven years, and we arrange and manage every other trade, so you never have to source anyone.
Do you only carry out full home renovations, or can I renovate a single room?
Which areas of London do you cover for full home renovations?
We work across London from our Hammersmith showroom, including Chiswick, Ealing, Fulham, Barnes, Chelsea, Kensington, Brentford, Richmond, Twickenham, Kingston and Wimbledon.
How is Arch KBB different from a general builder?
Unlike a general builder, we are a design-led renovation company. Every project starts with an experienced designer, not a builder, giving you better space planning, better product selection and one point of contact managing the whole process.
Can you take out a wall? Do you do extensions or lofts?
We can remove a structural wall to open up a room, or take out a chimney breast, as part of the work. We don’t do extensions or loft conversions.
