Property Development Services in London: From Site to Built Scheme
Development is about finding the right site, knowing what it can carry, buying or unlocking it on the right terms, and then delivering the scheme. Craftex supports landowners, investors and developers through every stage — feasibility, land, planning, design and construction.
Because we are also a design and build contractor, our development appraisals use real construction costs, and the team that assesses your site is the team that can build it.

Our development services
Who we work with
- Landowners who want to know what their land or building is worth with planning — and how to unlock it.
- Investors and family offices looking for a partner to assess, consent and deliver schemes.
- Developers who want feasibility, planning and construction from one accountable team.
- Owner-occupiers with underused buildings that could be converted, extended or redeveloped.
What a development appraisal tells you
A good appraisal answers one question: does this scheme work, and at what land price? We set out:
- What the site could carry — options for units, floor areas and uses within planning policy.
- Gross development value — what the finished scheme could be worth, based on comparable evidence.
- Build cost — from our own unit-by-unit cost plans, not rule-of-thumb rates.
- Fees, finance, planning obligations (such as CIL and Section 106) and contingency.
- Residual land value and profit — what the land is worth to a scheme like this.
- Programme and risks — consents, party walls, rights of light, neighbours and access.
Ways to unlock land
Not every landowner wants to sell outright. Depending on the site and your goals, the options include:
- Outright sale — a price agreed now, often conditional on planning.
- Option agreement — a buyer secures the right to purchase later, usually once planning is achieved.
- Promotion agreement — a promoter funds and manages the planning, then the land is sold and proceeds are shared on agreed terms.
- Development partnership — the landowner keeps an interest and shares in the value of the completed scheme.
Each has different risks and tax and legal consequences, so we always recommend independent legal and tax advice before you sign.
Have a site but not sure what it is worth? Send us the address. We check the planning history, constraints and development potential, and tell you honestly whether it is worth pursuing.

Evidence, not promises
Questions we are asked most
What is a development feasibility study?
It tests what a site could support — layouts, unit numbers and floor areas — against planning policy, cost and value, so you know whether a scheme is viable before you buy or commit.
How do you calculate build costs?
From our own construction experience and unit-by-unit cost plans, not generic per-square-metre rates. That makes appraisals more reliable.
What is the difference between an option and a promotion agreement?
With an option, a buyer gets the right to buy the land later, usually after planning. With a promotion agreement, a promoter funds the planning and the land is then sold on the open market, with proceeds shared on agreed terms. Always take independent legal advice.
Can you combine neighbouring sites?
Yes. Site assembly can create a larger, more valuable development plot. We assess ownerships, rights and planning potential before approaching owners.
Do you manage developments for investors?
Yes. Our development management service covers feasibility, planning, design, procurement and construction under one team.
Do I need planning before selling my land?
Not necessarily, but land with planning permission is usually worth considerably more. We help you weigh up selling now against pursuing planning first.
Do you work outside London?
Our core market is London, and we take on selected projects in the South East and major UK cities.
