Cellars, Garages and Gardens: How These Features Impact Property Value
Published 26 October 2026
Cellars, garages and gardens all increase property value, but in different ways and primarily depending on location, legal status and usability. In city centres, garages and cellars are more valued; on the outskirts and in rural areas, gardens are preferred. What always counts is that only properly registered and genuinely usable features are reflected in the price.
Summary
- Ancillary features have no fixed value increase; their impact on price is determined by location, condition, size and legal registration.
- In city centres, garages and lockable cellars are more valuable; on the outskirts and in villages, gardens are preferred.
- A garage with ownership rights or clear usufruct is valued differently from shared public parking.
- A garden can be an asset, but also a liability due to maintenance costs, slope, easements or unauthorised structures.
- A written valuation estimate will be provided within 24 hours; the estimate is non-binding.
What is ancillary property and why it matters
The Civil Code (Občanský zákoník č. 89/2012 Sb.) in § 510 defines ancillary property (příslušenství) as an auxiliary item belonging to and intended for the permanent use of a principal item. In a house, this might be a garage or garden; in a flat, a cellar or storage box. In practice, however, the key factor is how the item is legally arranged:
- a cellar or garage may be part of the flat unit, or a separate unit with its own entry in the Czech Land Registry (katastr nemovitostí),
- it may be a common part of the building assigned to your exclusive use (under the Civil Code § 1158 et seq.),
- a garden may be a separate plot with its own land register entry, or only a part of someone else's plot that you use.
For a buyer and for a property buyout company, this is a critical difference. What is not registered in the Czech Land Registry cannot be safely transferred and is poorly or not at all reflected in the price. For more information on registrations, see our guide to the Czech Land Registry.
Cellars: city centre versus periphery
A cellar alone rarely determines price, but the difference between locations is noticeable.
- City centre of a large city: flats tend to be smaller and storage space is scarce. A dry, lockable cellar makes the flat more usable and easier to sell. Buyers perceive it as a substitute for a pantry, storeroom or small warehouse.
- Outskirts and smaller towns: flats tend to be larger, often with a balcony or loggia, and a cellar is usually a standard feature. Its contribution to price is therefore smaller; buyers typically take it for granted.
Cellar value is reduced by damp, poor access, low ceilings, shared unlockable space, or a cellar that actually belongs to another flat. It is increased by larger floor area, dry condition, electricity connection and good access. No flat sum can be given; valuations are always based on comparison with similar sales in the given location. For guidance, see our description of valuation methods.

Garage and public parking: two different worlds
Parking is not all the same. Several situations are distinguished in valuation:
| Situation | Impact on price |
|---|---|
| Garage as part of the unit or a separate unit registered in the Czech Land Registry | Valued as a full property; the contribution to price is the highest. |
| Garage space with an ownership share | Increases price if the share is clearly linked to a specific space. |
| Rented or merely occupied space | Weakly reflected in price; it is an obligation that may not pass to the buyer. |
| Public street parking, resident zone | Not part of the property; may only slightly increase location appeal. |
In a city centre with limited parking, a garage is a significant competitive advantage. For houses on the edge of towns, where parking is by the house, its benefit decreases and depends more on condition and size. Equally important is the legality of the structure: a garage built without permission or contrary to documentation may cause complications under the Building Act (Stavební zákon č. 283/2021 Sb.) and reduces price.
Garden: when it is an asset and when a liability
A garden is one of the most variously perceived ancillary features.
When it increases price
- it is flat, well-maintained and directly adjoins the house or a ground-floor flat,
- it is a separate registered plot, ideally fenced with access from a public road,
- it is in an area where people seek homes with gardens, typically around towns.
When it becomes a liability
- it is steep, shady or neglected and requires investment,
- there is a risk of boundary dispute, or it is encumbered by an easement (věcné břemeno), such as a right of way or utility conduit (under the Civil Code č. 89/2012 Sb.),
- there are unauthorised structures on it or the garden is used without legal basis,
- the buyer does not want to bear maintenance and water costs.
A house with a garden is usually compared with similar houses in the area. The plot size and type (garden, built-up area, arable land) are shown in the Czech Land Registry. A garden with better development potential is valued differently from one that is purely decorative. Related information can also be found in our land purchase service.
How ancillary features are calculated into the buyout price
The buyout price is based on market value. Ancillary features are included in three steps:
- Verification of legal status – extract from the Czech Land Registry, unit entries, easements, charges.
- Condition assessment – cellar dampness, garage condition, garden maintenance, unauthorised structures.
- Comparison with similar sales – location and demand for the specific ancillary feature are taken into account.
For apartment buildings, income-based valuation is used, where cellars, garages or courtyards are assessed by the income they can generate. For these, an offer comes within 48 hours. For flats and houses, you receive a written offer within 24 hours with a breakdown of the calculation, so you can see how each part is reflected. The offer is non-binding and you can withdraw until the contract is signed.
What to prepare before sale
Properly prepared documentation prevents ancillary features from being overlooked or undervalued in assessment.
- Current extract from the Czech Land Registry and verification that the cellar, garage or plot are indeed registered to your property.
- Agreements on use for spaces, boxes or rented parts.
- Building permits or use certificates for the garage and other structures on the garden.
- Photos and condition description, if available, information about damp or renovations.
Also check for mortgages and enforcement proceedings; these are dealt with separately, see property purchase during enforcement. You can check the value roughly in free online property valuation.
Ownership is transferred to the buyer only by entry in the Czech Land Registry under the Land Registry Act (Katastrální zákon č. 256/2013 Sb.). Payment is made non-cash via a lawyer's escrow account; legal services are included at no additional fee.
