Our approach
We sell fewer homes than the big chains, and we know each one by its creaking stair and its best evening light.
Every property is handled by one named agent, from the first valuation to the day the keys change hands. No call centres, no handovers between departments.
We photograph every home ourselves, write the copy in plain language and publish a floor plan with each listing, so buyers arrive at viewings already knowing the layout works.
What we do
Four ways we can help, one team behind all of them
Whether you are moving for the first time or managing a small portfolio, the process starts with a conversation in one of our offices.
Buying
Early access to new instructions, honest feedback on condition and price, and an agent who attends every viewing.
Browse homes
Selling
A written valuation, professional photography and a launch plan agreed with you before anything goes online.
Book a valuation
Renting
Referenced tenants, clear agreements and a lettings manager who answers the phone when the boiler stops.
See rentals
Commercial
Studios, shops and offices for small businesses, with lease terms explained before you sign anything.

How selling works
From first call to completion in four clear steps
You always know what happens next, who is doing it and when you will hear from us.
01
Valuation visit
An agent walks the property with you, looks at recent sales on your street and gives a written figure within 48 hours.
02
Preparation and launch
Photography, floor plan and description are ready within a week. You approve every word before the listing goes live.
03
Viewings and offers
We accompany every viewing, report feedback the same day and check each buyer's position before an offer reaches you.
04
Sale to completion
Your agent stays in touch with solicitors and the buyer until the keys are handed over, with a weekly update by phone.

Presentation
Every listing is photographed, measured and written by the agent who sells it
We do not send a stranger with a camera. The person who will show buyers around is the one who chooses the angles, writes the description and draws the floor plan, so nothing in the listing promises more than the house delivers.
48h
From valuation to written figure
7 days
From instruction to going live
"We had two offers in the first week and Clara talked us through both, line by line, before we chose."

Reading an autumn market without the headlines
Asking prices tell you what sellers hope for. Time on market and the gap to the agreed price tell you what buyers will actually pay.
Ten things to check on a second viewing
The first viewing is about how a home feels. The second is about water pressure, phone signal, storage and the walk to the station at 8 am.
Preparing a home for photographs
Most buyers decide from the first six photographs whether to book a viewing. A few hours of preparation changes what those six pictures show.
