Pricing
Know The Fee Before You Commit.
Four ways to test a building, from a £15.99 automated check to an design-led feasibility. Answer a few questions and the price is on screen, not in an email.

Automated HMO screening.
Planning and Article 4 checks, local HMO information, property and location data, key planning considerations and initial development indicators.

Detailed data-led appraisal.
For existing buildings nationwide: commercial to residential, apartments, HMOs, co-living, mixed use and similar opportunities.
Around 30 minutes
Architectural Feasibility

Bespoke
Expert Session
Complex and larger projects.
Anything over 600m², development land, new build, masterplanning or a scheme with several strategies to test. We scope it properly first, then quote a fixed fee.
All fees include VAT.
Architectural Feasibility
Get Your Fixed Fee.
Eight questions, about a minute. Straightforward projects get a price on screen. Anything larger or more involved routes to a free Expert Session, because a scope we have not seen is not one we will put a number on.
Roughly how big is the existing building?
Gross internal area across all floors, in m².
What is it now?
What do you want it to become?
How many separate buildings?
How many design options would you like tested?
Heritage status
Do you have enough on the existing building?
Plans, surveys, brochures, photos or planning history that show what is there now.
Anything else that applies?
Leave these unticked if none apply. Each one changes the fee, and a masterplan or whole-site redevelopment is always scoped in a conversation rather than priced automatically.
Where do we send your fixed fee?
Your fee appears on screen instantly; these let us hold it for you and pick the conversation up if you want to talk it through.
We use these details to send you the fee and to follow up about your project. We do not sell your details or add you to a marketing list without asking. Privacy notice.
No payment yet. All fees include VAT. Larger or more involved projects route to a free Expert Session rather than an automatic price.
The Best Money I Spent Before Buying a Property
“I booked a feasibility study before committing to the purchase of a property I intended to convert into an HMO. The team were thorough, professional and, most importantly, completely honest. Although the outcome wasn't what I initially hoped for due to planning constraints, the study identified significant risks that could have cost me a substantial amount of money had I proceeded without proper due diligence.”
What Affects Your Fee.
Every fee is fixed before you pay. These are the things that move it, and the calculator asks about each one, so the number you see is the number you pay.
Where a project has several of these at once, we stop pricing automatically and talk to you first, through a free Expert Session.
£49.99 Or From £298?
Both start from the same data. The difference is what happens to it.

Everything in the automated appraisal, plus our design team: planning interpretation, sketch and layout testing, and a professional recommendation you can act on.
Automated Site Feasibility, £49.99
What You Get For £49.99.
The £49.99 appraisal is fully automated and data-led. It does not include architectural drawings or an design review.

We have been working with Ed and the team at Thistle Architecture on a complex office-to-residential conversion and roof extension project in Winchester, and the service throughout has been excellent. Ed has been proactive, commercially minded and solutions-focused from day one.
I've worked with Edward and Kaan on several planning applications now, all of which have resulted in positive outcomes. They consistently provide a high standard of work, are thorough in their approach, and understand how to present a strong planning case.
I decided to work with Ed and the team due to their experience in HMO conversions. I was purchasing my first building to convert and needed expert guidance. The whole process was so enjoyable and the results were fantastic!
Thistlearchitecture recently did the full planning application on a Hotel we own to which they gain planning permission to turn it into a 9 bedroom HMO. Great service throughout, always easy to get on the phone and very details with their work.
Ed and his team are always friendly, professional and positive. They are exactly the team you want when working on complex projects.
Used Ed and his team to put my property through planning etc.. couldn’t fault them, came up with some great ideas and drawings.. would highly recommend!
