The governing reference is the room
In hotel work the benchmark per square metre of gross floor area is secondary. What governs is investment per room, because the room is the revenue unit of the business and the viability appraisal is built on it.
Cost per room has one property that no area benchmark shares: it falls as the number of rooms rises. The reason is that the public areas are inside it. Reception, lobby, food and beverage, kitchen, stores, administration, staff areas and circulation arise largely independently of the room count and spread across more revenue units in a larger property.
A cost per room figure is therefore only usable together with the room count it was formed for. A figure from a 60-room property does not transfer to a 200-room property, even at identical category and specification.
The available ranges
For the three-star category in Germany, the documented range runs from about 50,000 euros at the lower end to around 200,000 euros per room, a factor of 4 within a single category. The range is therefore fourfold.
| Item | Value |
|---|---|
| Documented range, three-star category | 50,000 to 200,000 € per room |
| Spread within the category | factor 4 |
| Change since 2004, three-star category | roughly doubled |
| Change since 2004, luxury segment | close to tripled |
| Shelf life of a benchmark without updating | 3 years |
Part of that scatter is real and follows from concept and location. Another part follows from inconsistent survey bases. Older sources quote mid-market figures far below today's: investment costs in the three-star category have roughly doubled since 2004, and nearly tripled in the luxury segment.
A clear rule follows for use: hotel benchmarks age faster than in any other segment. A figure without a survey year is unusable, and a figure more than three years old requires updating whose uncertainty should be recorded.
What a cost per room figure contains
The boundary between the two is the real source of error, and it does not run where an investor assumes it does. Three of the excluded items can shift the total investment by an order of magnitude equal to the gap between two star categories.
| Usually included | Routinely not included |
|---|---|
| Construction cost of the building, spread over the room count | Site and its acquisition costs |
| Fit-out to occupancy standard | Special areas such as spa and conference |
| Furnishing of rooms and public areas | Underground parking |
| Technical equipment including kitchen installations | Ancillary costs of cost group 700 |
| Pre-opening costs: staffing, marketing, first stock |
The operating concept matters more than the category
Star rating is a coarse indicator, since it says something about specification, room size and furnishing level. The stronger driver is the operating concept, that is which areas the property provides at all.
The effect of each area decision can be estimated in advance. It therefore belongs in the operating concept rather than in a later cost negotiation.
| Area decision | Effect on investment per room |
|---|---|
| No conference rooms | lowers |
| No full restaurant, no production kitchen | lowers |
| Bar doubling as the breakfast area | lowers |
| Spa area | raises, partly without revenue contribution |
| Several food and beverage outlets | raises |
| Generous lobby | raises, without revenue contribution |
A concept without conference rooms, without a full restaurant and therefore without a large production kitchen and stores, with a bar that doubles as the breakfast area, needs a considerably smaller area programme per room. Investment per room falls accordingly, without any saving on room quality.
Conversely, spa facilities, conference capacity, multiple food and beverage outlets and generous lobbies drive area per room and therefore the benchmark upwards, in part without a direct contribution to revenue. They explain most of the dispersion within a single category.
For early cost estimating this means the operating concept, and the area schedule derived from it, come before any search for benchmarks. Only with that schedule can it be judged which comparison figures are relevant at all.
Room size as the second driver
Alongside the operating concept, room size acts directly on the benchmark. It is the single quantity that touches category, area schedule and investment at once.
A larger room acts across every cost group at once, and that is precisely where its leverage lies. No single specification decision reaches a comparable breadth of effect.
| What a larger room does | Quantity affected |
|---|---|
| More area per revenue unit | construction cost |
| Longer circulation runs | area and building services |
| Greater facade area per room | cost group 300 |
| Higher effort for fit-out and furnishing | fit-out and equipment |
The effect is therefore stronger than any individual specification decision. It acts on the whole area rather than on a single element.
Conversely, a compact and highly standardised room geometry is the most effective lever in hotel development. It permits industrial prefabrication of bathrooms, repeats across every storey, and reduces design effort and construction risk together.
For early cost estimating this yields two figures to be carried together: the room area and the share of room area within gross floor area. The second is the real efficiency measure in hotel work, because it shows how much of the built area generates revenue at all.
Ancillary costs in hotel development
Cost group 700 runs above average in hotel work, which per-room benchmarks routinely obscure because they are confined to construction and furnishing costs. It therefore has to be set separately.
Four causes act together, and the last is the least predictable. It follows state law and should therefore be settled before the site decision.
| Cause | Effect |
|---|---|
| Design effort for operating concept and area schedule | additional scopes of service |
| Involvement of operator and brand | further coordination loops |
| Specialist design for kitchen and spa installations | additional specialist designers |
| More demanding consent procedure | accommodation buildings count as special building types above certain thresholds |
The system of cost group 700 and the question of its base are set out in the article on ancillary construction costs under KG 700. It also sets out which items of that group are routinely understated.
The area benchmark as a cross-check
The benchmark per square metre of gross floor area does not replace the per-room view but checks it. Where the two results diverge markedly, an unusual area relationship is almost always present, meaning either very large rooms or a very high share of public areas.
Cost per cubic metre of gross volume is additionally customary in hotel work, and can say more than area where representative lobbies carry large clear heights. The system behind both measures is set out in the article on reference areas.
Fit-out and services are the cost drivers
Price movement in hotel development currently runs in opposite directions. Shell construction shows some relief, driven by easing material prices and a softening order book in the construction sector. Interior fit-out and building services, by contrast, remain at a demanding level.
This is felt particularly in hotel work, because interior fit-out carries a larger share here than in almost any other building type. A flat uplift on a total benchmark does not capture that divergence and systematically understates the fit-out component.
A growing item is added that older benchmarks barely contain: investment in digital infrastructure per room, which has moved over recent years from a few hundred to close to a thousand euros per room. The amount is small against the total investment, but it stands for a range of items that an old benchmark simply does not include.
