Can I Keep My House, or a Plot for My Family, and Put the Rest of My Land Forward?

Yes. A great many fields that could take homes sit behind a farmhouse, a cottage or a bungalow on the edge of a village, and the owner wants to stay. Nothing in the law of land or planning asks you to sell the whole holding in one piece.

What makes it work is the plan. Our option agreement identifies the land it covers on a plan attached to it, and the land on that plan is the only land the agreement touches. The house, the garden around it, the drive, the stables, and any plot you want to keep for a son, a daughter or a grandchild stay outside the line and stay yours. The line can follow a hedge, a fence or a new boundary drawn across open ground, as long as it can be drawn accurately.

Selling part of your land does raise practical questions that selling the whole does not, and the rest of this page takes them in the order a family usually meets them:

• The title. How one registered title becomes two.
• The land you keep. What the house needs from the land sold, and what the land sold needs from the house, once they belong to different people.
• The neighbours you will have. How councils expect new homes to be laid out next to an existing house.
• A plot for the family. How it can be set aside, and what the planning rules say about one house on its own.
• The mortgage. Why a lender with a charge over the whole title has a say in a sale of part.
• Tax on the home. How private residence relief treats a garden or paddock that is sold.
• Day-to-day life. What changes at the house while planning is under way, and what does not.

1. A plan is drawn. HM Land Registry's guidance for preparing plans says that transfers of part will usually need a plan showing the land being transferred. The plan must be drawn accurately to a stated scale, with a north point, and must allow the Land Registry to identify the land clearly on the Ordnance Survey map. Its preferred scale for fields and farms is 1:2500, measurements are given in metres to two decimal places, and a plan marked "for identification only" may be rejected. The seller signs it.
2. The deed is prepared on form TP1. Form TP1 is the Land Registry's form for transferring part of a registered title. It names the title number the land is being taken out of, describes the land by reference to the plan (for example, edged red), and has a panel of additional provisions where the solicitors set out the rights granted for the land being sold and the rights reserved for the land being kept.
3. The land sold gets a new title number. The Land Registry does not split a title simply because an owner asks it to. A new title comes into being when there is a transaction, such as a transfer of part. The land transferred is then registered under a new title number in the buyer's name, and your existing title carries on for the land you keep.
4. Any mortgage over the part sold is released. If a lender has a charge over the whole title, it releases the part being sold so that the buyer takes it free of your mortgage. The section on lenders below explains how that works.

Under an option agreement, these stages come at the end, not the beginning. The plan that marks the land in the agreement is drawn before signing, and the transfer of part is completed only once planning permission has been secured and the purchase goes through. Until then your title is unchanged, apart from the notice that records the option, which our guide to option agreements explains.

Roythornes, a firm of solicitors with an agricultural practice, puts it simply: when a title is split it is important to consider whether rights will be needed over the land kept or the land transferred, and rights of access, rights for services, drainage arrangements and future maintenance obligations may all need to be documented. The table sets out what each of those means at a house with a field behind it.

Rights of this kind are called easements. When a sale of part is registered, the Land Registry's practice guide on easements explains that no separate application is needed for the easements in the transfer: registering the transfer is enough. The grant or reservation of a legal easement is a registrable disposition, and the Land Registry enters the benefit on the register of the land that enjoys the right, which lawyers call the dominant land, and a notice on the register of the land it crosses, the servient land. So the right of way to your stables, or the right for the new homes' drainage, shows on both titles for any future buyer to see.

The same guide notes that on a transfer, the buyer may acquire easements over land the seller keeps even without an express grant, under section 62 of the Law of Property Act 1925 or the rule in a case called Wheeldon v Burrows. That is one reason solicitors prefer to write every right down expressly, so that nothing is left to be implied later.

Access is the right that matters most to a field, and a strip of land between a field and the road can change everything. Our guide to access and ransom strips explains why, and how highway boundaries are checked.

With your house treated as an existing neighbour whose privacy and light the council protects. Councils set out how far new homes must stand from existing ones in a design guide, a design code or a supplementary planning document, and the figures differ from council to council. Wakefield Council's District Design Code, a supplementary planning document adopted in June 2026, is a clear recent example. It says its separation distances are there to protect residential amenity and privacy, to ensure a minimum garden depth and to prevent overbearing and terracing effects.

The code adds that for buildings above two storeys, extra distance or stepping back of the upper floors may be needed to keep privacy, and that shorter distances may be accepted where a higher density is needed or a site is constrained, provided the scheme shows that privacy, daylight and overshadowing are still dealt with.

Distance is only part of it. The same code's guidance on transitions between land uses sets out two ideas that apply to any field behind a house:

• Gardens meet gardens. Where existing buildings back onto a site boundary, new development should adopt a similar back-to-boundary arrangement, to maintain privacy and security and a logical relationship between neighbouring buildings. In practice, new gardens meet your garden, rather than a new road running along your fence.
• Height steps down. Where larger buildings are proposed next to smaller ones, the design must make a gradual transition in height and massing, to avoid abrupt changes and to prevent overbearing or excessive shading. A bungalow or cottage beside the site is exactly the kind of smaller building this is meant for.

The distances also work together, and your own house counts in them. Suppose the living room windows at the back of your house sit 8 metres from your rear fence, and a new two-storey home is planned beyond it with its own living room windows facing yours. Under Wakefield's figures the new home needs a rear garden of at least 10.5 metres, which would leave the two sets of windows 18.5 metres apart, short of the 21 metres required. The new home would have to stand at least 13 metres back from the fence instead. That is why the depth of the garden you keep, and the way your windows face, are measured at the start of any layout.

These are not concessions to whoever sold the field: councils apply them to any scheme next to an existing home. When a scheme reaches outline planning, the parameter plans show where the built area, the access and the open space are expected to go, which our guide to how long planning takes explains. That is when the relationship between the new homes and the garden you keep is first set down in the planning documents.

You can keep the land for one. Whether a house can be built on it is a separate question, decided by its own planning application, and the honest answer depends on where the plot is.

Setting the Plot Aside

There are two ways to keep a plot out of a land deal. The simplest is to leave it outside the line on the agreement plan, so it stays on your title and nothing about the agreement touches it. The other is to give or sell the plot to the family member before any agreement is signed, by a transfer of part of its own, so that it has its own title number in their name. Either way, the plot needs the same things as the house: a way in, services, drainage and a fixed boundary, and its position has to be settled before the agreement plan is drawn, because the layout of the field has to work around it.

A gift of land to a family member has tax consequences of its own, for Capital Gains Tax and inheritance tax, and the right way to do it depends on the family's circumstances. That is a question for your accountant before anything is transferred.

What the Planning Rules Say About One House on Its Own

The National Planning Policy Framework of August 2026 treats land inside and outside settlements very differently. Inside a settlement, policy S4 says development should be approved unless the benefits would be substantially outweighed by any adverse effects. Outside settlements, policy S5 allows only certain forms of development, including limited infilling within groups of houses, and it says that isolated homes, which are those lying outside settlements or groups of houses, should not be approved other than in line with policy HO11. Policy S5 also allows homes on land physically well related to an existing settlement and served by infrastructure, where unmet need for housing is evidenced. A Housing Delivery Test result below 75% is enough for that need to be treated as evidenced, while a shortfall in the five-year housing land supply counts as evidence of unmet need to be weighed, not as an automatic finding. Green Belt land sits outside S5 and has its own policies.

Policy HO11 in the August 2026 framework supports an isolated home in the countryside only in these circumstances:

• there is an essential need for a rural worker, including someone taking majority control of a farm business, to live permanently at or near their place of work;
• the home would be appropriate enabling development to secure the future of a heritage asset;
• it would reuse a redundant or disused building and enhance its immediate setting;
• it would subdivide an existing residential building;
• its design is of exceptional quality, truly outstanding and significantly enhancing its setting.

So a plot in the middle of open fields, away from any village, is hard to get permission for unless one of those applies. A plot within a village, or filling a gap within an existing group of houses, starts from a far better position. A plot beside a field that later gains permission for homes is judged on its own merits when its own application is made: where the council's plan draws the settlement boundary, and whether a single house there would be well related to the homes around it, are what decide it. No one can promise that a plot will follow the permission on the field.

If the field is on the same title as the house and your mortgage is secured on that title, yes. A mortgage is a charge over the land in the title, so the lender has a security interest in the paddock as well as the house. Before the part being sold can pass to the buyer free of your mortgage, the lender has to release that part from its charge. This is called a partial release, or a release of part.

A lender can agree to this. In a Financial Ombudsman Service final decision on a complaint about Nationwide (reference DRN-4492500), the ombudsman recorded that Nationwide Building Society confirmed it does allow part of a property to be released from its security, and noted that a release of this kind commonly involves the sale of part of the grounds or garden to a neighbour or developer, or the sale of outbuildings. Nationwide also said that each request is considered individually.

What the lender looks at is its security. The same decision shows the reasoning: in that case the owner wanted to turn one house into two, and the society's concern was that the value of its security would fall by more than half. The ombudsman found that both parties to a mortgage have to be content with any change to it. A lender asked for a release is weighing up what its security will be worth once the part has gone, so a paddock that is a small share of a property's value is a very different request from a proposal that takes away half of it.

• Find out whether the field or paddock is on the same title number as the house. Your title register shows it.
• Check whether your mortgage is secured on that whole title, or only on the house.
• If it is, tell your solicitor early, so the lender is asked about the option and, later, about the release in good time.

Where the field is on a separate title with no mortgage on it, none of this arises, and the house's mortgage is not affected by the agreement at all.

When you sell your only or main home, private residence relief normally means there is no Capital Gains Tax on the gain. The relief also covers garden and grounds sold with the house, or separately before it, up to a limit the law calls the permitted area. HMRC's Capital Gains Manual says that the permitted area is 0.5 hectares, about 1.24 acres, including the site of the house itself, and that if the garden and grounds do not exceed 0.5 hectares, relief is automatically available for the whole area, as long as the land was garden or grounds on the date it was sold.

Four rules in the manual explain why selling part of a garden, or a paddock behind a house, can lose that relief:

The manual gives its own example of the last rule: a house with 2 hectares of land, of which only 0.2 hectare is garden and the rest is used for a trade, gets relief for the house and that 0.2 hectare, not for the whole 2 hectares.

Is a Paddock Garden or Grounds?

Sometimes. HMRC's definitions page describes grounds as enclosed land surrounding or attached to a house, serving chiefly for ornament or recreation, and it lists paddocks and orchards, providing there is no significant business use, among the land that should not necessarily be excluded from garden and grounds. A paddock where the family keeps its own ponies may therefore be grounds. A field let for grazing, cropped by a farmer or used in a livery business is in use for another purpose and is not. Our page on paddocks and small sites looks at the planning side of a paddock next to a home. Most fields that are put forward for homes are farmland, and for those the relief does not come into it at all: the gain is taxed in the ordinary way, as our guide to tax when selling land for development explains.

Why the Order of Sales Matters

Because the test is applied on the date the land is sold, a family that sells the house first and the paddock later can find the paddock no longer qualifies, however long it was enjoyed with the home. The manual says land disposed of separately after the dwelling-house will not qualify for relief. For a family thinking of moving during the planning period, that is worth knowing before the house goes on the market. Under an option, the date that counts for Capital Gains Tax is usually the date the option is exercised, which the tax guide explains.

The second trap is size. Where garden and grounds go beyond 0.5 hectare, HMRC's manual treats the separate sale of part as possible evidence that it was not needed for the enjoyment of the house, although it accepts that the inference may be wrong in some cases, such as a sale of part within the family or a sale forced by financial necessity. Even then, the manual says, a good reason for the sale does not by itself mean the land was within the permitted area: the extra land is relieved only if it passes the reasonable enjoyment test.

Very little day to day. You live in the house, use the garden, keep the horses on the paddock and farm the field exactly as before, because nothing passes to us until completion. What you will notice are the visits, and later the publicity, that every planning effort involves.

• Survey visits. Ecologists, tree surveyors, drainage engineers and a topographical surveyor need to walk the field, some at dawn or dusk in the bat season. Every visit is arranged with you beforehand, and when the house is next door that includes which gate to use and where to park. Our option agreements guide lists what each survey involves.
• Pre-application talks. The council's officers and the highway authority are consulted before an application is made. We tell you before anything about your land becomes public.
• The application goes on the council's website. The law requires the council to publish the address, a description of the proposal, and how and by when people can comment, with a closing date no earlier than the end of 14 days from publication.
• Notices and letters. For an ordinary application the council must either display a notice on or near the land for at least 21 days or write to the adjoining owners and occupiers. For major development a newspaper notice is added. Your house adjoins the site, so you may well receive a neighbour letter about your own field.
• Comments from neighbours. Neighbours can support or object. Councils judge an application on planning grounds, and privacy, overlooking and the scale of the new homes are among the matters they weigh.

Under the Development Management Procedure Order 2015, major development means ten or more homes, or a site of 0.5 hectares or more where the number of homes is not yet known. If the scheme on your field is of that size, the newspaper notice is added to the site notice or neighbour letters.

If you decide to sell the house while the planning work is going on, a buyer will see the application on the council's website, and it is part of the history of the land you are selling next to.

Building, when it comes, happens after completion, when the field is no longer yours, and it has to follow the planning permission and the conditions attached to it.

Our option agreement is built around the plan. Before anything is signed, we agree with you where the line runs: which field, which part of it, and what stays with the house.

1. A free desktop review of the whole holding. We look at the title, the access, the constraints and the council's position, and we show you where we think the line could sensibly run. You tell us what you want to keep and why.
2. The plan is drawn and agreed. The land in the agreement is marked on a plan you have seen and agreed, along with how the land you keep will be reached and served once the sale happens.
3. A price in writing. One figure for the land on the plan, agreed at the start, set above what that land is worth today, and not reduced if the planning costs rise.
4. We run the planning. Surveys, design, consultation, the application and, if needed, an appeal, all paid for by us, at our own cost and risk. The agreement continues while any application or appeal is being decided.
5. You carry on as before. You keep living in the house and using all of your land, including the land in the agreement, until completion.
6. Completion. Once planning permission has been secured, we complete the purchase of the land on the plan and you receive the agreed price. The transfer of part is registered and the house keeps its own title. If permission is not secured, you keep all of your land and owe us nothing.

Because the land you keep is settled on the plan before signing, the planning work is designed around it from the first sketch: the access, the drainage and the edge of the scheme next to your garden are all part of the same layout. We also put money towards your own solicitor's and land agent's fees, so having the plan and the agreement looked at properly costs you nothing. A free desktop review of your land is the simplest way to find out where the line could run on your own holding.
