I have the site. What can I build here?
The site is identified, the option fee is on the desk, the architect has been asked for a fee proposal, and the investment committee paper is due Friday.
In 48 hours, desktop feasibility gives a small developer the commercial answers needed before committing fees: what the planning policy allows, what the scheme could yield at sensible density bands, indicative GDV against BCIS-informed build cost, an indicative residual land value range, a specialist study schedule, and a risk register written for lender, JV partner or IC challenge. It is sized for backland, infill, edge-of-settlement, conversion and small brownfield sites of one to twenty units.

What desktop feasibility delivers
| What you receive | What it tells you |
|---|---|
| Planning policy read | Whether the scheme is policy-compliant or relies on the tilted balance at NPPF paragraph 11(d) |
| Scheme options at density bands | How many dwellings the developable area supports |
| BCIS-informed indicative build cost | Whether the cost stack supports the bid |
| Indicative GDV from comparable evidence | What the scheme is worth at completion |
| Abnormal cost provisions | What the constraint stack adds to the build |
| Indicative residual land value range | Whether the price the vendor is asking is supportable |
| Constraint-triggered specialist schedule | What further work is needed and what it costs |
| Risk register | What an investment committee, lender or JV partner will challenge |
The report is written for bid/no-bid, offer revision, architect brief, and IC pack use. See the site feasibility study (2026 UK guide) and what is included in our 48-hour desktop pack.
Four packs sized to four decisions
| Pack | Decision | Buyer stage | Price | Best for |
|---|---|---|---|---|
| Site Appraisal | Is this site worth a feasibility study? | Bid or pre-screening | From £199, 48 hours | Sealed bids, shortlists, walk-away calls |
| Feasibility Intelligence (default for identified sites) | What can I build, at what cost, against what residual land value? | Pre-acquisition, pre-architect, IC paper | From £895, 48 hours | Option deadlines, IC papers, lender or JV conversations |
| Pre-Application Pack | How do I walk into pre-app prepared? | Pre-app booked in the next month | From £1,995, 48 hours | Council pre-app meetings on identified sites |
| Planning Intelligence Pack | How do I get to validation alongside the architect? | Submission stage | Tailored, 48 hours | Application packs alongside architect drawings |
Feasibility Intelligence is the default pack once a site is identified and a commercial decision is due. In our experience of the small-developer market, a coordinated feasibility study through traditional consultancy routes typically runs £3,000 to £8,000 over four to eight weeks.
Feasibility before architect, before pre-app
Feasibility usually costs less when it runs before architect concept design and before pre-application advice with the local planning authority, because the cost stack is not yet committed and the scheme is still cheap to change. Feasibility commissioned after architect, after pre-app, and after specialist work is usually the most expensive order: a small developer who has already paid an architect for concept work on a 12-unit infill site cannot easily unwind that fee if the residual land value does not support the asking price.
The wider buyer-stage workflow sits on the development land due diligence page.
Send the boundary today, receive the feasibility on Day 2
If the site is identified and a decision is needed inside 14 days, the 48-hour Feasibility Intelligence is the action that materially reduces risk on the architect fee, the option fee, the sealed bid, or the IC paper.
- Day 0: send the site boundary, the asking price or option terms, and the intended use.
- Day 1: we confirm scope, pack and any abnormal-cost flags worth investigating.
- Day 2: full feasibility report delivered, with scheme options, indicative GDV, BCIS-informed cost stack, residual land value range, specialist schedule, and risk register.
Specialist sequencing, including flood risk assessment under GOV.UK flood risk assessment guidance for planning, sits in what reports you need for planning permission. For wider planning context across application types and site characteristics, see GOV.UK planning permission guidance.
The price ladder. £199 to walk away from the wrong site. £895 for the feasibility. £1,995 to walk into pre-app. Tailored to submit.
What this desktop report does not replace. Desktop feasibility is pre-acquisition screening evidence. It is non-statutory, non-valuation and non-design. It is not a chartered RICS Red Book valuation, a formal viability appraisal, an MRTPI planning representation, or an architect's design feasibility study. Indicative GDV, cost and RLV figures are ranges based on comparable evidence and BCIS data, sized for early-stage commercial decisions, not formal valuation.
