One of the most common questions when making a hotel investment: "How many rooms can we build on this land?" That's actually not the right question.
Because being able to fit 20 rooms onto a plot or property doesn't mean you should build a 20-room hotel.
Room count in hotel investment isn't just an architectural decision. It's a strategic decision that directly affects investment cost, operating expenses, staffing needs, total revenue, occupancy rate, room rate, common areas, guest experience, and the investment's payback period.
So when determining room count, you should ask not just "how many rooms fit?" but "what's the right room count for this investment economically, operationally, and in terms of guest experience?"
1. First, determine the land's or building's capacity
The first step is understanding the physical capacity of the property you have. Land size, floor area ratio, footprint, floor count, setback distances, existing structure, common area needs, parking, and technical areas are evaluated together here.
This study can produce scenarios like 8, 12, 16, or 20 rooms. But this is only the first step. Because the room count that's physically achievable and the room count that's right for the investment may not be the same.
2. The difference between "maximum rooms" and "optimum rooms"
I think this is one of the most important distinctions in hotel investment. Maximum room count is the highest number of rooms you can physically fit onto the property. Optimum room count is the room count that's really right in terms of investment cost, revenue, operations, guest experience, and long-term operating performance.
For instance, you might fit 20 rooms onto a plot. But if you build 20, rooms could shrink, common areas could narrow, the garden could shrink, you might have to give up on a pool, a parking problem could arise, and staff and operations areas could fall short.
In contrast, a 14-room project could produce a much more spacious, higher-quality, higher-priced product. In that case, 14 rooms could be a better investment than 20.
3. Concept affects room count
In the previous article we discussed how to define hotel concept. Room count is one of that concept's natural consequences.
For example, an 8-room boutique hotel offering personalized service and a 40-room, more standardized hotel don't have the same operating model. In a small boutique hotel you might want to offer more space and a more personal experience per guest. In a larger hotel, economies of scale become more important.
So the concept-first, then-room-count approach is a healthier starting point for most small and mid-scale hotel investments.
4. What room count does your target guest require?
You also need to think about the target guest when determining room count. For example, a small boutique hotel aimed at couples on a weekend getaway and a hotel aimed at families, groups, business travelers, or long-stay guests will have different needs.
Does your target guest expect more common areas, bigger rooms, more rooms, more social space? The answers directly affect room count.
5. Don't forget room size when determining room count
Investors sometimes focus only on room count. For example, "Let's build 15 rooms." But the real question should be: "How many square meters will each of the 15 rooms be?"
Because 15 small rooms and 15 spacious rooms don't produce the same product. Room size affects comfort, furniture layout, bathroom size, luggage space, working area, and overall guest experience. So the right balance needs to be found between room count and room quality.
6. Leave enough space for common areas
A hotel isn't made up only of bedrooms. A project has many areas — reception, lobby, breakfast area, kitchen, corridors, stairs, elevator, storage, technical spaces, and staff areas.
Shrinking these to add more rooms can look profitable at first glance. But it can weaken guest experience. Especially in boutique hotels, common areas are an important part of the hotel's identity. So it's worth asking: "How much of the hotel's overall experience am I giving up to add one more room?"
7. Room count determines revenue potential
Of course, more rooms theoretically raises revenue potential. For example, 10 rooms × 365 days = 3,650 sellable room-nights; 20 rooms × 365 days = 7,300 sellable room-nights.
But we know not all of these rooms will sell every night. That's where occupancy rate comes in. So room count alone isn't revenue. Room count × occupancy × average room rate need to be evaluated together.
8. ADR is an important indicator in room count decisions
ADR, Average Daily Rate, is the average daily room rate. Say we have 15 rooms, 70% occupancy, 5,000 TL ADR. The basic annual room revenue calculation could be 15 × 365 × 70% × 5,000 TL. That's roughly 19.16 million TL of room revenue.
The same calculation for 20 rooms increases revenue. But a very important question arises here: will my ADR or occupancy rate drop as I go up to 20 rooms? If building more rooms lowers the hotel's pricing power and occupancy performance, deciding based only on room count isn't right.
9. Balance room count with occupancy
Building a bigger hotel doesn't always mean an easier-to-fill hotel. This matters a lot especially in seasonal areas. For example, you might sell all 20 rooms in high season. But in low season, 8 of the 20 could stay empty. In a 10-room hotel, the same regional demand might fill 7 out of 10.
So the investor should think not "How many rooms can I sell?" but "How many rooms can I sustainably sell throughout the year?"
10. Season length affects room count
Especially in tourism regions, season matters a great deal in the room count decision. An area operating 12 months a year and one operating 5-6 months need different investment models. When the season is short, building more rooms can raise revenue in high season.
But in low season it can increase the burden of fixed and semi-fixed costs like staff, energy, maintenance, cleaning, and marketing. So when determining room count, you need to ask "How many rooms can I sell in high season?" as much as "How will I carry this hotel in low season?"
11. Staffing needs also grow with room count
As room count rises, operational needs change too. More rooms can mean more cleaning, more laundry, more consumables, more reception operations, and more maintenance.
Especially on the housekeeping side, room count directly affects staff planning. So when increasing room count in feasibility, staff cost needs to be recalculated too.
12. Room count also affects technical infrastructure
A 20-room hotel and an 8-room hotel don't have the same technical needs. For example, hot water capacity, water tank, hydrophore, electrical infrastructure, AC systems, internet infrastructure, and laundry capacity can change with room count.
So when increasing room count in the architectural project, the technical infrastructure needs to be updated accordingly.
13. More rooms doesn't always mean more profit
Here we reach one of the most important mistakes investors make: "If we can fit another room, let's add it." This approach isn't always right.
One more room adds revenue. But it also creates cost — construction, furniture, bathroom, textiles, housekeeping, energy, maintenance, staff. So you need to calculate how much net contribution a new room really adds to your investment.
14. Calculate investment cost per room
A very useful indicator in hotel investment can be turnkey investment cost per room. For example, if total investment is 40 million TL and room count is 10, the investment per room is 4 million TL. When the same investment is turned into a 15-room project, the cost per room changes.
But you shouldn't think of this just as total investment / room count. Because common areas, land, technical infrastructure, and other investment items are also part of the total cost. Still, it's a very useful indicator for comparing different project scenarios.
15. Also calculate revenue per room
Similarly, annual revenue per room can be calculated. For example, at 5,000 TL ADR and 70% occupancy, a room's theoretical annual room revenue is 5,000 × 365 × 70% = 1,277,500 TL.
Based on this figure, scenarios can be built: 10 rooms → 12.78 million TL, 15 rooms → 19.16 million TL, 20 rooms → 25.55 million TL. But remember these are gross room revenue figures, and operating expenses, commissions, taxes, and other costs need to be calculated separately.
16. RevPAR can offer a more realistic indicator
Looking only at ADR isn't enough in hotel investments. You might have a high room rate but low occupancy. So an indicator like RevPAR (Revenue per Available Room) can provide a more meaningful comparison.
Simply, RevPAR = ADR × Occupancy rate. For example, 5,000 TL ADR × 70% occupancy = 3,500 TL RevPAR. This indicator helps evaluate room rate and occupancy at the same time.
17. Test room count with scenarios
If I were making a hotel investment, I wouldn't decide based on a single room count. I'd build at least three scenarios: Scenario A — Small (10 rooms), Scenario B — Medium (14 rooms), Scenario C — Large (18 rooms).
Then I'd calculate, for each scenario, investment cost, ADR, occupancy, annual revenue, staff cost, energy cost, operating expenses, net operating income, financing burden, and payback period. This way, instead of "Which has the most rooms?", you can answer "Which scenario is the healthiest investment?"
18. Small and large hotels have different advantages
A small hotel's advantages can be more personal service, a stronger boutique character, lower staffing needs, and less operational complexity. A large hotel's advantages can be higher total room revenue, economies of scale, being able to offer more services, and spreading some fixed costs across more rooms.
Which one is right depends on the investment's location, concept, and financial structure.
19. Sometimes fewer rooms can be more valuable
This approach matters a great deal especially in boutique hotels. For example, instead of a standard 20-room hotel, a 12-room boutique hotel with more spacious rooms and stronger common areas can sell at a higher price.
Guests can pay more for more space, better design, a calmer atmosphere, and more personal service. So sometimes the right investment strategy is increasing the value created per room, rather than increasing room count.
20. Feasibility should determine room count last
I think the right order is: concept, target guest, location/property, preliminary architectural project, room scenarios, investment cost, revenue estimate, operating expenses, profitability, and finally the room count decision.
In other words, room count isn't a decision the architect makes alone. It's a decision the investor, architect, and operations side need to evaluate together.

Conclusion
The biggest mistake when determining room count in a hotel investment: getting stuck on "How many rooms fit in this building?"
The right question should be: "What room count gives the best result for this investment's target guest, concept, price level, and operating model?" Because there's no simple equation like more rooms = more revenue. Sometimes 20 rooms can be a better investment than 15. Sometimes 10 rooms can be far more valuable than 20. What matters isn't using maximum capacity; it's finding the right capacity.
When determining room count in a hotel investment, before making the final decision I'd definitely compare three different scenarios: fewer rooms + high experience, medium room count + balanced investment, more rooms + high capacity. And in the end I'd look at: "In which scenario is there the healthiest balance between the money I'm investing, the risk I'm taking on, and the business value I'll create?"
Because a good hotel isn't the one that builds as many rooms as possible. It's the one that can build the right experience and the right economic model with the right number of rooms.
