Three things sit on this site and each is worth something different: a piece of land, a set of machines, and a trade. A report that adds them together without saying which is which is of no use to anyone.
1. The context of the instruction
Take a representative brief of the kind that recurs regularly. An owner-operator holds a vehicle wash centre with a quick-service area — a roll-over gantry and high-pressure bays, vacuums, a small plant room and pay point, sometimes an oil-change or accessory-fitting position. The property occupies a corner plot on a busy urban road, with two accesses. He wants the asset valued to prepare a disposal, while a partner is separately contemplating separating ownership of the property from the operation.
The configuration concentrates everything that makes this asset class methodologically interesting: the building is light — the structure is not what carries the value — the plant weighs heavily, and the bulk of the worth is borne by the pitch and the traffic. It is the same family of problem addressed in our note on a petrol station, where property, business and supply contract are unpicked.
2. The basis of value and the scope
First step, always: fix the basis of value and the scope. As our guide to the stages of a valuation in Morocco makes clear, a figure means nothing unless it is tied to a precise definition and to a date. Here one generally adopts the market value of the asset as a going concern, to which a question of allocation attaches:
- The walls — the corner land, the slab, the concrete aprons, the canopy and the plant room: the property component in the strict sense.
- The business and the operation — custom, the pitch as a source of trade, know-how and organisation: the value of the activity, distinct from the building.
- The equipment — gantries, tunnels, bays, vacuums, water recycling, payment terminals: treated separately, because they depreciate and are sometimes held under a hire or finance-lease arrangement.
The allocation is not a theoretical exercise. It governs a partial disposal — selling the property and keeping the operation, or the reverse — and any eventual separation of property from operation. A report that aggregates everything without distinguishing the components leaves the reader unable to price either half, and useless in a negotiation over one of them. The Red Book bases of value are chosen accordingly, at the scoping stage.
3. The RICS method adopted — and why
A wash centre belongs to the family of trading properties, addressed by RICS VPGA 4. The logic is the same as for a filling station or for an industrial asset: value arises from the flow of trade, not from the masonry. But the wash centre has a distinguishing feature — a light building and heavy plant — which invites two approaches to be cross-checked rather than one to be isolated.
- The income approach. One reconstructs a normalised trading result — wash and service receipts against throughput, less staff, water, energy, maintenance and licence costs — then capitalises it at a yield reflecting the risk of the pitch and of the operation. This is what captures the value of the traffic and of the corner position.
- The cost approach. Land, valued by comparison of bare sites, plus the cost of rebuilding the light structure, plus the depreciated value of the plant on reinstatement-cost logic. It objectifies the “land plus machines” component and serves as a cross-check.
- Direct comparison. Used only as a guard rail: sales of auto centres are scarce and heterogeneous, and the sample is rarely sufficient to conclude on its own.
Why cross-check? Because the income approach taken alone can run away with itself where trade is exceptional or merely cyclical; and the cost approach alone ignores the whole advantage of the pitch. Bringing the two together produces a coherent range with a land floor beneath which the asset does not fall — the land retains its worth, subject to what redevelopment would cost.
How the two approaches are reconciled
The French original works this section without committing to any number, and describes its example as purely pedagogical, never to be read as a price or a scale. The same discipline is kept here. On the income side: a normalised annual trading result is capitalised at a yield reflecting the risk, giving a value for the asset in operation. On the cost side: the corner land valued by comparison of bare sites, plus a light structure rebuilt, plus plant taken from its cost new and then depreciated for its actual age and condition — a gantry several years old is plainly not worth what it cost. The two results are then reconciled: where they converge the value is solid; where they diverge, the valuer explains why — trade out-performing, plant worn out, a premium pitch. It is that reasoning, and not a figure, that makes the report usable in a negotiation. Reports comply with Red Book standards, delivered in 5 to 8 days, with a firm quote within 24 hours.
4. The corner site and the traffic: the real driver of value
For a trade that lives on passing traffic, the pitch is not an amenity: it is the first determinant of throughput. At equal area, two wash centres can trade very differently according to whether the plot sits on a corner or is landlocked. The valuer assesses on site:
- Visibility and exposure to the road — a driver washes where he sees, in passing.
- The direction of traffic and the ease of entry and exit — a corner often offers a double access, which keeps the queue moving.
- Daily passing traffic and its nature: residential, through route, or industrial estate.
- Manoeuvring and stacking space, and the capacity to absorb peaks without congestion.
All of this feeds the throughput assumption in the income approach. This is where the corner advantage is monetised: it is not added as an arbitrary premium, it shows up in the trade assumed — and therefore in the capitalised value. The same reading of frontage and road exposure runs through our note on a car showroom on a Casablanca boulevard.
5. Depreciating plant: what loses value, and what is not yours
This is the technical particularity of the file. A wash centre is, for a good part of its worth, a fleet of machines: a gantry or tunnel, high-pressure bays, vacuums, compressors, water treatment and recycling, payment terminals. Two principles govern their treatment.
- Depreciation. In the cost approach one starts from the cost of replacement new and deducts depreciation for age, wear and obsolescence. Well-maintained recent equipment retains value; an ageing fleet calls for a discount and signals capital expenditure to come.
- The ownership perimeter. Not everything necessarily belongs to the seller. Some equipment is hired, held under a finance lease or covered by a maintenance contract: it then falls outside the value of the walls, and sometimes outside the business being sold. The valuer distinguishes what has become a fixture forming part of the building from movable or separately financed plant.
That rigour avoids the classic trap: valuing machines at their price new, or including equipment that will not pass to the buyer. The fine technical characterisation of an installation — mechanical condition, compliance — is a matter for a specialist inspection, distinct from a valuation of worth, and the report says so where it is needed.
6. Redeveloping the land: the advantage of a light build
Where a filling station carries land that is awkward to redevelop — buried tanks, remediation — a wash centre generally presents a more favourable profile: a light building, ground that is less heavily equipped, and demountable structures. The corner site therefore retains real alternative-use potential — but under strict conditions.
A value in an alternative use is only adopted where that use is legally and physically possible: this is the highest and best use test. In practice the valuer verifies compatibility with the zoning and the development potential — the method is set out in our article on valuing land against its zoning and development potential — together with the feasibility and cost of putting the site back into a developable state (demolishing the concrete aprons, removing the plant). Where a change of designated use is in issue, it has to be confirmed with the competent planning department, checking the planning information note; the arithmetic of that kind of arbitrage is worked through in our note on a plot rezoned for higher density. Failing a permitted alternative use, the land is worth what it is worth in its present use — which returns the analysis to the income approach, its starting point.
7. The deliverable and the points of vigilance
The report follows the structure of a valuation complying with Red Book standards: description and site findings, basis of value and valuation date, assumptions and the sources of the trading data, application of both methods (income and cost) with a reasoned reconciliation, the allocation between walls, business and equipment, and explicit reservations. The points of vigilance on a file of this kind:
- Trading data. The valuer does not invent them. The fuller the record — receipts, water and energy consumption, accounts — the more the conclusion is documented and verifiable line by line.
- The status of the plant. Owned, hired, on finance lease — to be clarified before any conclusion on value.
- Water consumption and compliance. A sensitive cost line, to be built into the normalised result.
- The contractual and occupational position. Whether the centre is operated directly, under a lease or under a management agreement — to be confirmed with your own legal adviser under the regulations in force.
The same walls-and-business discipline applies across operator-occupied leisure and service assets — see our treatment of a gym or fitness club.

Note:this worked example describes a valuation methodology (RICS VPGA 4, income and cost cross-checked) for information. No amount, rate per square metre, yield or depreciation scale is quoted: the figures in the French original are labelled illustrative examples rather than market data, and they are rendered here qualitatively for that reason. The technical characterisation of plant and water consumption are matters for dedicated inspections; the contractual position (lease, management agreement) and any change of designated use must be confirmed case by case with your own legal adviser and with the competent planning department, under the regulations in force.
