About Silver Stag Construction
A local building firm at Sonning Common, run by its director.
Silver Stag Construction Ltd has been registered at Companies House since 2 October 2018 and works out of Sonning Common, a few minutes from Henley-on-Thames. James Richardson is a director of the company, and he is the name clients use in their reviews — “James and his team”, “James is a conscientious builder”. Extensions, renovations and one-off new builds, in Henley and the villages around it.

Where we are
Based at Sonning Common, with the registered office at Easter Barn, Blackmore Lane. We build in Henley-on-Thames, Caversham, Emmer Green, Gallowstree Common, Kingwood Common, Peppard Common and Watlington — a patch small enough that James can come out for a look and still be on site while your job runs.
What we take on
Extensions from a single added room up to multi-storey work with a large footprint; renovations from one room to a complete overhaul, including rewiring, plumbing, structural changes, kitchens, bathrooms and decorating; and the occasional one-off new build. Domestic work for homeowners — not commercial contracts.
Who is on your job
James and his team, plus our own regular trades brought in for specialist work — the kitchen fitters, glaziers, electricians and plumbers clients have seen on site. We do not publish a headcount, because the honest answer is that it depends on the stage of your job.
A registered company, and only the badges we hold
We do not claim trade accreditations we have not earned. Silver Stag Construction Ltd is a Federation of Master Builders member firm and a limited company registered at Companies House — and that is the complete list. Both are checkable in under a minute using the links below.

What that means for you →How we work with you
A quote you can follow
Clear, detailed and itemised, with no hidden costs — so you can see what each part of the job is costing you and make decisions with real numbers rather than a single figure at the bottom of a page.
You hear about problems early
“They handled any issues or problems… with a calm and thoughtful way.” Old houses hold surprises. We tell you the day we find one, along with the options and what each of them does to the programme.
Written contracts, proper hand-over
The scope, the stages and the terms are written down before anything starts, and the job ends with a snag list walked with you rather than a van quietly driving away.
We keep the disruption down
You are living in the house while we work in it. Dust protection, sheeted routes, noise kept to sensible hours and a site tidied at the end of the day — these are part of the job, not a favour.
We work alongside your architect, structural engineer and building control where a project has them, and bring in our own regular trades and suppliers — kitchen fitters, glaziers, electricians and plumbers — where specialist work is needed.
What we stand by
The three things our reviews keep saying.
A quote you can read
Clear, transparent and detailed quotations for every job, with no hidden costs. One client put it better than we can: not the cheapest, but “comprehensive, transparent and coherently structured”.
Calm when things go wrong
“They handled any issues or problems… with a calm and thoughtful way.” Every older house has something behind the plaster. What matters is that you hear about it the day we find it, with options attached.
Work you would ask back
“We are delighted with the extension they built for us… We've since asked them back to do two other jobs for us.” Repeat work from the same household is the only review metric we would actually bet on.
One of our favourites
“Thank you for the excellent job you and your guys did in constructing our single storey extension. You employed excellent tradesmen in all areas, but particularly the bricklaying and roofing guys were fantastic.”
