Land and Development: Realising What a Site Can Actually Deliver

Assessing Development Potential

Before any conversation about value, it is worth understanding what the land can realistically carry, whether you have a single plot or a larger strategic holding, because the questions are much the same even if the depth of work differs.

The physical constraints come first: the topography, access, flood risk, ground conditions, trees and ecology, and the relationship to the existing settlement. These set the practical envelope long before policy enters the picture, so a field that floods, or one with no realistic vehicular access, behaves very differently from one that adjoins the settlement boundary with services close by.

Then comes the policy position, which in plain terms is whether the planning system is likely to support development here at all, and if so at what scale and in what form. A site inside or adjoining a defined settlement, on previously developed land, or within a Local Plan allocation starts from a very different footing than open countryside in a protected landscape or Green Belt.

A feasibility exercise on a site, whatever its size, draws those threads together and considers:

• The likely scale and form of development the site can support, broadly how many units and of what type, and the principal physical and policy hurdles in the way.
• A realistic view on planning likelihood given where the site sits in relation to settlement boundaries and protected designations.
• A rough sense of what it would take to move from where you are now to a position where the land or project can be sold or built.
• Whether the value is close to the surface or some way down, so you know whether to act now or hold.

Having masterplanned new communities, sold sites for hundreds and thousands of homes, and bought and developed residential, extra-care and industrial schemes over the years, I am mindful that landowners are often told a site "has potential" without anyone explaining the conditions attached to that word. I would rather set those conditions out plainly at the start. A single house is a relatively simple endeavour by comparison, which is partly why I find this side of the work so satisfying, and I can advise on small plots and larger schemes alike, leading the work myself where it suits and bringing in the right consultant where a scheme needs formal, modelled input or an application taken through to determination.

Strategic Route Choice: Auction Versus Maximising the Value

When a renovation or development project comes up for sale, the path of least resistance is to send it to auction, and a fair few agents do exactly that because it is quick and it is easy. Auction has its place, for a genuinely difficult site, a forced timescale, or a buyer pool that really does live in the auction room, and it may well be the right route depending on the circumstances. The mistake is treating it as the automatic answer, because it tests a narrow audience under time pressure rather than presenting the opportunity properly to the people most likely to pay for it.

The alternative is to sell strategically, which means understanding the development angle, presenting it with development-grade marketing, and putting it in front of the right buyers so the asset is made to compete. The Old Chapel is a good example of this in practice:

• Rather than selling it at auction, it was handled as the conversion and development opportunity it actually was, with bespoke marketing built around what the building could become.
• That presentation spoke to developers and converters directly, on the terms they assess opportunities, rather than to a general auction crowd.
• Marketing to the right pool, with a clear development narrative, creates competition and evidence for the price, which is what protects and lifts the figure.

The honest position is that auction is one option among several, not the default, and may be exactly the correct route in the right circumstances. The choice turns on the site, the timescale and where the value really sits, and my job is to advise on the route that gets the most from the asset for you.

Options, Promotion Agreements and Outright Sale

Once you have a feel for the potential, the question becomes how to realise it, and there are several broad routes, each suiting a different owner.

• Outright sale is the simplest, you receive the money now and pass the planning risk to the buyer, which suits a straightforward site, a need for certainty, or an owner who would rather not wait. The trade-off is that a buyer carrying planning risk prices it in, so you typically receive less than the land might be worth with consent.
• An option agreement is where a developer or promoter pays for the right to buy your land within a set period, usually while they pursue planning, often at a price linked to market value with an agreed discount. This keeps you as the owner while someone else funds and drives the planning effort, and it can suit a patient landowner who wants to share in the uplift without carrying the cost.
• A promotion agreement works differently again, the promoter funds and runs the planning process and the land is then sold on the open market, with the promoter taking an agreed percentage of the proceeds. The interests are more closely aligned than under some options, because the promoter only earns by maximising the sale price, though their fee comes out of your receipt.

The detail matters a great deal with options and promotions in particular, the length of the term, the discount, the trigger, and what happens if planning stalls, so these are agreements to read carefully with proper legal advice rather than skim. If you are entering into one, the most important thing is that you are properly guided so your position is protected. In respect to which route fits, there is no single right answer, it turns on your timescale, your appetite for risk, the strength of the planning position, and frankly how much of the process you want to be involved in. I am happy to talk it through against your particular circumstances and give you an honest view of the trade-offs.

How Land Is Valued, and Where the Uplift Comes From

It is worth being candid about where land value actually arises, because it is rarely in the soil itself. The uplift comes when the planning system permits a more valuable use, and the scale of it is striking: on the government's own land value estimates, agricultural land averaging around £23,000 a hectare can be worth in the region of £2.67 million a hectare once it has residential planning permission, well over a hundred times more (gov.uk). That gap is what everyone in this market is really discussing, and it is why I keep returning to the planning stage, because the work done there is what moves a site from one value to the other.

Land is generally valued on a residual basis, which works back from the value of the finished scheme, deducts the cost to build it, the finance and the developer's profit, and leaves the residue as what the land is worth. That figure is not free of obligations, and a credible view nets them off honestly:

• Planning obligations and contributions, whether through Section 106 agreements or the Community Infrastructure Levy where it applies.
• Requirements such as affordable housing provision.
• Biodiversity net gain, now a standard requirement on most consents.

All of these reduce the residual land value, and a figure that ignores them is a figure no developer would ever pay. I can value land and give you a properly reasoned view of what it is worth, reflecting those obligations rather than flattering the conversation. What I do not provide is a formal RICS Red Book appraisal, and where that specific product is required for a lender or a formal process, I will tell you so plainly. It is also worth holding onto an important distinction: planning crystallises land value, which is not the same thing as development value, and it is the land value, once the principle is established, that puts you in the strongest position when it comes to a sale.

Selling Land and Projects Well: The Process and the Pitfalls

Selling land is not the same as selling a house, and the pitfalls catch out owners, and frankly agents, who treat it that way. The groundwork matters a great deal:

• Assembling the title and identifying any constraints, easements, covenants and ransom strips.
• Understanding access and services, which a serious buyer will investigate closely.
• Matching the information to the scheme, because a small residential plot or a barn conversion needs far less than a larger application of, say, ten units or more, where ecology, landscape, transport and drainage evidence all come into play. I can help you judge what level of preparation a given site actually warrants.
• Getting the development narrative straight, so the opportunity is presented on the terms buyers actually assess it.

Any of these can stall or reprice a deal late in the day if they surface as a surprise, so doing the work upfront protects your position and your timescale.

One of the most common questions I hear is some version of "why isn't my land selling?", and the honest answer is usually that it has been overvalued or simply put out cleanly with no narrative, no evidence and no targeting. Land sold quietly to the first developer who knocks may transact quickly, but it rarely tests the market. A properly marketed site or project, presented with a clear planning narrative and offered to the right pool of buyers, gives you competition and evidence for the price instead.

The common errors I see are selling too early before the planning position is understood, accepting an unconditional offer that looks tidy but undervalues the uplift, sending a development project to auction by default, and agreeing heads of terms without proper advice on the conditions buried within them. Patience, applied with a clear view of the destination, is usually rewarded in this market, though patience is not the same as inaction.

The Local Plan, Site Allocation and Housing Need

Underneath all of this sits the Local Plan, the document each council uses to decide where development should and should not go, and where your land sits in relation to it is one of the strongest signals of its prospects. A site allocated for housing in an adopted plan starts from a position of policy support, which lowers risk and lifts value, whereas a site in open countryside or a protected landscape faces a far harder route, even if it is otherwise attractive.

The national backdrop is worth keeping in view too. The current National Planning Policy Framework was revised in December 2024, it sets a standard method for assessing housing need pointing to around 370,000 homes a year across England, and it introduced the concept of "grey belt" land within the Green Belt, all of which shifts the ground on which local decisions are made (gov.uk).

That national picture creates real, time-sensitive opportunities at the local level:

• Where a council cannot demonstrate a five-year supply of deliverable housing land, as has been the case in Stroud, the presumption in favour of sustainable development carries more weight, and sites that would not ordinarily be supported can come into play on their individual merits.
• With housing need acute and targets rising, authorities are often keen to support robust, well-evidenced applications, and a constructive relationship with the local authority counts for a great deal.
• When a council reviews its Local Plan it runs a call for sites, and putting your land forward, properly promoted with the right evidence, is how unallocated land can become allocated. That is a longer game, and not every site succeeds, but it is often where the most significant value is created, and it rewards owners who engage early and credibly rather than waiting to be approached.

From my background I can give you a view on where each authority's plan has got to and whether your site's moment looks near or some years off, and lead or coordinate the work to promote a site through the process where that is the right play.

Adam's View

Having spent close to twenty years on the development and strategic land side before I set up my own agency, masterplanning new communities, selling sites for thousands of homes and taking land through planning on transactions north of £130m, the thing I would want you to take from this is that there is real value in development, and a specific kind of value-add in getting the planning right. That value is made at the planning stage and then captured at the point of sale, by understanding what a site can realistically deliver and then choosing a strategy that maximises it rather than reaching for the auction catalogue by default. That combination of a genuine development eye and a strategic approach to selling is what I bring as your agent, and where formal appraisals, applications or promotion are needed I draw on years spent in development and strategic-land roles to lead or steer that work, bring in the consultants I trust, or advise you on the sale. I would rather give you an honest view of a site that is harder than it looks than talk up a number that will not survive a developer's appraisal, because my interest is in you making a good decision rather than a quick one.

It is worth being clear about where my focus sits at the moment. My primary aim is to sell plots and development opportunities for people, build a foothold in the land market so owners come to me, and act as agent on larger schemes that need significant investment to bring forward. On a smaller plot, that might mean simply preparing a vision and getting the principle of development established, through a Permission in Principle or an outline consent, rather than a fully detailed scheme, because developers often prefer to re-design to suit their own needs, and the principle alone is usually enough to crystallise the land value and put you in the strongest position for an open-market sale. On a larger scheme that needs serious planning investment, the work is more about advising on the best contractual route to maximise your return, whether that is a promotion or option agreement, a hybrid of the two, or an open-market sale with overage clauses to capture future uplift.
