Planning changes to your home shouldn't feel risky.
Most homeowners don't struggle with ideas. They struggle with knowing what to do first. We help you get clear before you commit, so decisions feel calm, costs make sense and nothing spirals later.
Approach
Big ideas. Serious money. A lot of unanswered questions.
Most people come to us excited, and quietly uneasy. They are thinking things like:
- “Do we actually need planning, or are we assuming?”
- “Is this worth the money, or are we forcing it?”
- “How much does this really cost once everything's included?”
- “What if we start, and then realise we've made a mistake?”
Builders say one thing. Friends say another. Searching online just makes it noisier. That hesitation is sensible. It's also exactly where projects go wrong, because most renovation stress doesn't come from the building work. It comes from decisions made too early, without enough information.
“It's not really about design. It's really about what order decisions should happen in.”
01
A free 15-minute Clarity Call
We talk through where you are and what you're trying to achieve. You come away knowing the sensible next step, even if that step is to wait.
02
The Clarity Pack
Before anyone commits to drawings or builders, we test what's realistically achievable on your home: layouts, planning, structure and cost bands, with a written recommendation and a roadmap.
03
Design, planning, drawings and the build
Only once the direction is clear do we design it properly, take it through planning, draw it for the builder and, if you want us there, support you on site. You decide at each stage whether to carry on.
The Clarity Pack
Know what's possible before you spend serious money
Most homeowners don't regret spending money on their home. They regret spending it in the wrong order.
The Clarity Pack is the step before drawings, planning or builders. James visits, measures up and talks it through with you both, then over 3 to 4 weeks we test the layouts, the planning position, the structure and the likely cost, and give you a written recommendation and a roadmap.

What we help with
- 01Home renovations and extensionsMost people who come to us know the house has to change. What they don't know is where to start, what it will really cost, or whether the council will say yes.
- 02New build homesBuying a plot or replacing a house is the biggest decision most people ever make about a home. The worry is committing to it before you know what the site will actually allow.
- 03Heritage and conservationYou bought the house for its character. The worry now is changing it without damaging what you love about it, or getting stuck in a planning process you don't understand.
- 04Passive House design and retrofitCold rooms, draughts and heating bills are usually what bring people here. The worry is spending a lot on upgrades that don't fix the problem, or fix one thing and cause another.
- 05Interior architecturePlenty of homes have enough space. It is just arranged for a way of living that isn't yours, and the worry is spending on a refit that leaves the real problem in place.
- 06Planning advice and feasibility studiesThe fear is spending thousands on drawings for something the council refuses, or the budget can't stretch to. The answer is to test the idea before you commit to it.

About
I'm James, a RIBA Chartered architect based in Woking.
Most of my clients haven't done this before. My job is to help them avoid the mistakes that only become obvious after money has been spent.
That means being honest about what works, what doesn't, and when it's better to pause rather than push ahead.
No hype. No pressure. Just clear thinking and sound judgement, from someone who does this every day.

“It's changed how we live. We still regularly have to pinch ourselves.”
Words from clients
14 Google reviews, all five stars
“James took our initial thinking and came back with some fantastic designs, challenged our thinking and rescoped areas where needed.”
“He listened to our thoughts and preferences, took time to answer questions really clearly and show us options, before we agreed on a final plan.”
“Clear, concise design and drawings made the construction process extremely smooth.”
“…fantastic design proposals and great imagery to help us visualise the different options. The technical drawings he prepared were very accurate which helped make the build process as straightforward as it could be.”
“…James listened attentively, understood the brief well and produced an imaginative design which used the limited space available to its best advantage.”
“…worked for us after we had a poor experience with another architect. James was quick, thorough and a delight to deal with.”
“Lots of wow factor in the design & we are very pleased with the results.”
“In the nearly 40 years I’ve been working in the construction industry I have worked with and for many good architects. James Williamson Architects trumps them all.”
