Selling part of a large garden can release money while allowing you to keep your home. The opportunity depends on what the new plot can actually be used for, how it will be reached and serviced, and what the division does to your remaining property. This guide explains how to assess those questions under German law.

Start with the property you want to keep
A large garden may tie up money and require more work than you would like. Selling a section can therefore be attractive, especially if you want to stay in your current home. Begin by deciding what that home should look and feel like afterwards. Consider the garden you use, access to the garage, space around the terrace and the proximity of any future building. An adequate number of remaining square metres does not guarantee a convenient layout.
This guide concerns the physical division of land into separately transferable property. Selling an undivided percentage share in the whole property is a different arrangement. Creating condominium ownership is different again. The German terms and procedures described here apply to property in Germany, with particular attention to North Rhine-Westphalia, or NRW. They should not be read as instructions for subdividing land in another country.
Prepare two possible layouts using an existing site map. Add the house, outbuildings, parking, trees, inspection chambers and possible access routes. Label your drawings as preliminary ideas. A fence or hedge is not reliable evidence of the legal boundary. Official records and, where necessary, work by an authorised surveyor establish the relevant position.
Consider a hypothetical NRW property of 1,200 square metres, with approximately 450 square metres proposed for sale. The remaining 750 square metres tell only part of the story. If the sale area includes a long access strip, less of it is available as a useful building and garden area. Compare keeping the land, selling a part and selling the whole property. Our broader guide to selling land provides the surrounding sale process.
Separate building potential from permission to divide
Creating a new cadastral parcel does not create a right to build. A Flurstück is a parcel identified in the German cadastre; its recorded shape and number do not confirm a permitted development. Start with the applicable planning position. A binding local development plan may control the proposed use and building envelope. Within a built-up area, section 34 BauGB is particularly relevant. Land outside such areas is subject to a different assessment. A neighbouring house alone is insufficient evidence.
Ask an appropriate planning professional to examine an actual layout. Where could a building stand, and what remains once access, required clearances and parking are considered? Include the existing house in this assessment. The new boundary must not leave it with unresolved access or building regulation problems. A line that appears sensible on an aerial image may pass too close to an existing structure.
Under section 7 of the NRW building regulations, division approval is required for specified categories, including developed land and land with approved construction or qualifying construction under the permit exemption procedure. Statutory exceptions include an appropriate certificate from an authorised surveying professional. The surveyor and building authority should identify the correct procedure for your case. There is no sound basis for saying that every division is automatically exempt.
Where development potential drives the expected price, consider a formal preliminary building decision, known as a Vorbescheid. It addresses the particular questions submitted and is not a complete building permit. Have the questions framed around a defined project on the proposed parcel. Informal encouragement from an authority is useful orientation, but it has a different status from a formal decision.
Make the access route usable and legally secure
For a rear plot, examine the entire journey from the public road to the intended building. Can vehicles turn into the entrance? Where will deliveries stop? What access and operating space will emergency services require? The answer depends on the proposed development. Do not rely on a single universal width quoted online, or assume that a route suitable for walking will satisfy every other purpose.
One option is to include a dedicated access strip in the land sold. Another is to keep the strip and grant rights over it. Shared ownership of an access area introduces further coordination. Compare the practical effect of each option: traffic near your windows, manoeuvring, parking conflicts, maintenance and the ease of selling either property later. A slightly different boundary may be more valuable than maximising the area offered for sale.
German public-law and private-law arrangements require separate attention. The NRW building regulations set requirements for access and recognise a Baulast, an obligation recorded by the building authority. A private easement, or Grunddienstbarkeit, can secure defined use for the owner of another property under section 1018 BGB. One does not automatically replace the other. Have the proposed documents checked together.
Define the route and permitted uses clearly, including walking, driving and relevant users. Also settle cleaning, winter maintenance, repairs and cost sharing. Construction access deserves its own discussion: heavy deliveries may need arrangements beyond everyday residential access. If you will continue living beside the route, think through an ordinary weekday and a period of building work before accepting the layout.
Investigate utilities before calling the plot serviced
Water, drainage, electricity and telecommunications need feasible connection arrangements. Ask the relevant network operators and municipal drainage service where connections could be made and under what conditions. A pipe or cable in the street does not establish the available capacity, the connection point or the cost of reaching the new parcel. Existing service to the front house does not answer those questions for a second property.
Collect available service plans and identify anything uncertain. Pay particular attention to infrastructure that would cross the proposed boundary. The existing house may drain through land intended for sale, while the new plot may need services beneath the driveway you retain. Where records are incomplete, discuss suitable investigation with the appropriate technical professional. Marking an assumed line on a drawing does not resolve an unknown route.
Compare separate connections with any shared arrangement using both initial and future costs. Who owns each installation? Who can enter the other property for inspection or repairs? Who restores paving after excavation, and how are bills divided? Have the necessary rights assessed by the notary. A right of way should not be assumed to cover every utility installation and access requirement.
Check the proposed drainage of rainwater, levels and gradients as well. Retaining walls, trees, fences and outbuildings may constrain the layout or require alterations. Obtain advice on the permissibility and cost of relevant changes before adding them to the sale proposal. A short working list should record each issue, the responsible organisation, the available answer and what remains unresolved. This produces a precise description of the plot's services rather than a broad claim that everything is already connected.
Give the surveyor a workable brief
Once the basic feasibility and a worthwhile layout are established, commission the required surveying work. NRW uses authorised surveying bodies, often publicly appointed surveying engineers known as ÖbVI. Provide more than a target area: include the intended access, existing buildings and the constraints identified during the planning review. Otherwise, a technically accurate survey may record a boundary that does not suit the eventual project.
Keep three stages distinct: surveying and formation of parcels in the cadastre, division in the land register, and transfer of ownership. A land-register property can contain more than one cadastral parcel. Düsseldorf's official service information describes local surveying and incorporation into the cadastre. Ask the surveyor and notary to coordinate the steps required for your particular sale.
Request a case-specific cost breakdown identifying the included work and possible additional charges. Clarify the treatment of site work, boundary procedures, required plans and cadastral processing. A quoted figure for surveying should not be mistaken for the full cost of creating and selling the new property. Nor should a general processing estimate become a promised completion date without checking the dependencies.
Prepare a current land-register extract, cadastral map, building records and information on registered rights and public-law obligations. The house sale checklist can help organise records for the existing home. Ask each participant for current lead times and the information needed before their work can proceed. Coordinate these into a realistic sequence, allowing for outstanding decisions. Boundary markers on site do not by themselves entitle a prospective buyer to occupy the land or start construction.
Compare total property value and available cash separately
The price received for the new plot is not an equal amount of additional profit. You are selling an asset and changing the value of the home you retain. Compare the undivided property's value with the retained property's value plus the net sale proceeds. A property valuation should consider both layouts, including the smaller garden, access obligations and privacy after development.
Use this purely illustrative calculation. Assume the undivided property is worth €780,000, the new plot sells for €230,000 and the retained home is worth €610,000. Together, the latter two figures total €840,000. Assume €35,000 of preparation, division, connection and agreed selling costs. That leaves €805,000, or a potential €25,000 improvement before individual tax and financing effects. These are invented planning figures, not a valuation, fee quotation or market forecast.
Now test a less favourable outcome. If the plot sells for €210,000 and the costs rise to €45,000, the combined result is €775,000, keeping the assumed retained value unchanged. That is €5,000 below the original €780,000. The comparison explains why a strong headline price is insufficient: costs and the value of the remaining house can determine whether the division makes financial sense.
Cash availability is a separate calculation. If the lender requires €80,000 repayment to release the sold land from its security, €230,000 proceeds minus €35,000 costs and that repayment leave €115,000 before tax. Repayment also reduces debt; it must not be counted again as lost value in the asset comparison. Obtain the lender's release conditions before committing the expected proceeds to another purchase or project.
Resolve tax and contractual questions before committing
Have the tax position checked before fixing a sale date or relying on a minimum net amount. For private property sales, the ten-year rule in section 23 EStG is an essential starting point. Your adviser needs the acquisition history, method of acquisition and use of the property. The date of the new survey does not answer the tax question. Gifts, inheritances or business circumstances may require additional analysis.
Living in the house does not automatically exempt a separately sold garden parcel. In case IX R 14/22, Germany's Federal Fiscal Court held that the separated undeveloped land did not qualify for the owner-occupation exemption through use of the retained house. This does not mean every partial land sale is taxable. The holding period and individual circumstances still matter. Obtain a specific calculation rather than deducting a guessed percentage.
A German property sale contract requires notarial recording under section 311b BGB. If the parcel has not yet been finally surveyed, the notary must assess how it can be described with sufficient certainty and what further steps are necessary. Discuss area discrepancies, price adjustments, missing approvals and what happens if the intended division cannot proceed.
The draft should also address cost allocation, existing charges, lender releases and access or utility rights. Align payment conditions, possession and permission to carry out works. Do not promise a particular development while its permissibility remains unresolved. Present the documented position clearly, use the notary for legal drafting and obtain tax advice from the appropriate tax professional.
Present a sale proposal that buyers can evaluate
A useful sales proposal explains the intended area, the stage reached in the division process and the evidence supporting the proposed use. Distinguish approved matters from pending applications and early design ideas. An illustrative house layout can help a buyer understand the opportunity, provided its provisional status is clear. Similarly, an approximate area should not appear to be the final surveyed measurement.
Create a compact information pack containing the location, area, boundary proposal or survey status, planning documents, access concept and utility information. Record known costs and the responsibilities for outstanding matters. This helps buyers assess their own design and financing. It also makes competing offers easier to compare: a higher price subject to many unresolved conditions may offer a different outcome from a lower price with a clear route to completion.
For an initial enquiry about selling part of your land, describe the location, total area, approximate sale area and existing buildings. Explain whether you intend to remain in the house, how access might work and which records you already have. These details provide a basis for discussing the information needed for valuation and marketing. Building decisions, surveying, legal drafting and tax calculations remain with the relevant specialists and authorities.
Proceed when three things align: the intended use is sufficiently established, both properties will function after separation, and the financial comparison remains worthwhile with a sensible allowance for uncertainty. If one fails, reconsider the boundary or retain the land. A successful division should give you useful financial flexibility while leaving a home you are comfortable continuing to own.
