Site Assembly
Land next to someone else’s often has more potential together than it does alone.
From joint ventures to complex multi-owner sites, our team negotiates the agreements that turn separate plots into one deliverable scheme.
Site assembly: bringing landowners together to unlock greater value
Some of the best development opportunities do not sit within a single boundary. If your land adjoins a neighbour’s, promoting the sites together can unlock a larger, more viable scheme, one that is more attractive to the planning authority than either plot would be on its own.
Bringing multiple landowners together raises real questions: how access is arranged, how existing land values are calculated, and how any uplift in value is fairly shared between everyone involved. Our approach covers access and site arrangements, valuing existing land and sharing uplift, joint venture and collaboration agreements, selecting the right promotion partner, and adapting agreements as plans evolve. Our Chartered Surveyors, working alongside our Chartered Town Planners, have extensive experience guiding landowners through exactly this, from the first conversation through to an agreed way forward.
It is rarely straightforward, different landowners often have different priorities, timeframes and expectations, and getting everyone aligned takes patience as much as expertise. But where it works, the results speak for themselves: sites that would never have gained consent individually can come together into a scheme the planning authority actively wants to see.

When landowners can’t agree on value
Site assembly depends on everyone agreeing how value gets split between neighbouring landowners. When that stalls, or when a compulsory purchase affects one party’s land differently to another’s, independent advice can get the negotiation moving again.
Common questions about site assembly
The process of bringing together two or more adjoining landowners to promote their land jointly for development. Combining plots can unlock a larger, more viable scheme than either parcel would achieve individually.
A larger, well-configured site is often more attractive to housebuilders and planning authorities than a smaller one with awkward boundaries or limited access. Promoting jointly can significantly increase the value and viability of what you have.
Through a carefully structured agreement that takes into account each landowner’s existing land value and their proportionate contribution to the scheme. Getting this right at the outset avoids disputes later, and it’s one of the most important parts of our role.
A formal legal agreement between two or more landowners setting out how the site will be promoted, how costs and proceeds will be split, and how decisions will be made. We help negotiate and structure these so everyone’s interests are properly protected.
That’s common, and it’s something we manage as part of the process. Getting landowners aligned takes time and patience, but it’s rarely insurmountable with the right advice and a clear framework everyone has agreed to.
Agreements need to be flexible enough to adapt as planning progresses, site conditions change, or market circumstances shift. We build in that flexibility from the start rather than treating the first agreement as the final word.
