Site Assembly in London: Neighbouring Plots, One Consented Site

Site assembly combines neighbouring plots and ownerships into one site that can carry a bigger scheme than any of them alone. We agree every owner's share first, then take the whole site through planning.

Schemes from £3M to £150M GDV

Assembled sites often move a scheme into this range. We look at what the combined site could carry.

Our expertise in site assembly

Assembly fails when owners feel played off against each other. We set the rules for everyone before the planning work starts.

  • Finding the opportunity

    Backland strips, side plots and adjoining gardens that unlock a scheme together.

  • Ownerships and rights

    Titles, access, rights of way and rights of light checked before anyone is approached.

  • Agreed valuations

    Each owner's share set on an agreed basis, in writing.

  • Mixed deals

    One owner sells, another keeps a share: the structure fits each owner.

  • One planning strategy

    One design, one application, one uplift event for the whole site.

  • Built by us

    We stand ready to build what is approved. See development management.

How site assembly works

We look at your plot and its neighbours and tell you whether assembly is worth pursuing.

We approach the other owners with the numbers, not a sales pitch.

Option, promotion or sale terms agreed in writing, the same structures we use on single sites.

We design and submit the combined scheme. See our planning services.

Sell at consented value and share the uplift, or build with us.

Site assembly: questions

What is site assembly?

Bringing neighbouring plots and ownerships together into one site, so a larger and more valuable scheme can be designed and consented. It is often how backland, garden and garage sites become viable.

Can site assembly support large residential schemes?

Yes. Depending on planning potential, location and access, an assembled site can carry schemes of 20, 50, 100 or more homes.

How is the uplift shared between owners?

On pre-agreed terms, usually in proportion to the land each owner contributes at an agreed valuation basis, settled in writing before the planning work starts.

Do all the owners have to sell?

No. Assembly can mix sellers and stayers: one owner sells a strip, another takes a share of the uplift.
