Business case · 8 August 2026
Sixty square metres below the house, a sauna, a jacuzzi and the Jeker outside the window. Here is what it can earn, what could stop it, and the one decision that is worth more than all the others combined.
Frank owns the house. I live in the attic apartment, I would run the B&B on the ground, and the arrangement is that I keep what it earns — he retains what covers the tax the business creates for him. How we formalise that is a later conversation.
The space has not been renovated. The aannemer is waiting on a specification. Novasol have made an offer. Neither the contract nor the building plan is signed, which means every decision in this document is still live — and a few of them stop being live soon.
I live in the building. Nobody competing with us can put champagne in a guest's hand in ninety seconds.
That is the one durable advantage here, and it holds under every scenario below. Remote hosts cannot chill a bottle, lay a breakfast or heat a sauna from across town. It is why the add-on business in section 08 is worth building no matter who ends up filling the calendar.
Maastricht's Huisvestingsverordening splits tourist letting in two, and the difference between the halves is the difference between a business and a hobby.
| Regime | What it covers | Night cap |
|---|---|---|
| Art. 2.1(1)(a) toeristische woningverhuur | A zelfstandige woning — self-contained, own kitchen, own entrance | 60 / year |
| Art. 2.1(1)(b) toeristische kamerverhuur | Rooms or part of a home, where the hoofdbewoner lives in the remaining part | none |
Article 2.4 caps letting at 60 nights a year — but it names only subsection (a). Build the space as a self-contained apartment and it is capped by law, with fines of €2,500 and €5,000. Build it as rooms within the house, with me living in the rest, and it is not caught at all.
The intended arrangement already satisfies half of this. The B&B is part of the house and I live above it, which is precisely the condition subsection (b) turns on — "waarbij de hoofdbewoner in het overige deel verblijft".
But living above is necessary, not sufficient. Subsection (b) covers a wooneenheid, a deel van een woning or a kamer. A woning is defined as zelfstandig — self-contained, with its own facilities. Give the space its own kitchen and its own entrance and we are letting a whole self-contained dwelling, which is subsection (a) at 60 nights even though I live upstairs.
The determining feature is the kitchen. A private bathroom is normal in a B&B and changes nothing. A full independent kitchen is what makes a dwelling self-contained. For a €280-a-night wellness stay guests want a kettle, a fridge and good coffee — not a kitchen. Easy to get right, but only if the brief says so instead of leaving it to the aannemer's default.
Art. 2.1(1)(a)
€13,500/ yr
60 nights, hard legal ceiling. Own kitchen and own entrance are exactly what triggers it.
Art. 2.1(1)(b)
€46,800/ yr
208 nights at 57% occupancy. No night cap. Maximum four weeks per individual stay, which no couples booking will ever reach.
Decided by the builder
€33,300/ yr
Determined entirely by a specification nobody has written, for a contractor who is currently waiting.
This is the most valuable unwritten document in the project. Not the website, not the contract — the fit-out brief. Section 10 is a draft of it.
Novasol have proposed €225 net per night to us, against a guest price of "+/- €280", flat all year, minimum two nights. To test that, I priced the closest real comparable I could find: Dormio Resort Maastricht's "Aqua Wellness" — 53 m², two people, private outdoor sauna and hot tub, in Maastricht. Prices read live from their own booking engine, and quoted all-in: cleaning, made beds, towels, tourist tax for two, booking fee. Directly comparable to €280.
Observed nightly rates, Aug 2026 – Feb 2027, against a flat €280.
| Check-in | Type | Nights | €/night |
|---|
The annual peak is not summer. The Christmas-market weekends outprice mid-August by €75 a night. Weekend check-ins run 15–40% above midweek in the same week, rates fall sharply with length of stay, and in peak weeks the operator raises the minimum stay to three nights rather than holding two.
€280 flat is the market's blended average presented as if it were the market's constant. On a February midweek the market is €212 — a flat rate prices us above the nearest real comparable exactly on the nights that need filling. On peak weekends the market reaches €382 — and under a net-rate deal we would never see a cent of it.
A seasonal ladder beats a flat rate. Roughly €220–240 low-season midweek, €280–300 shoulder, €330–380 on summer and event weekends, with a two-night minimum rising to three in peak weeks. Maastricht hands us the peaks on a calendar: carnaval, three André Rieu weekends in July, TEFAF in March, Preuvenemint in August, the marathon in May, and the Christmas markets.
| Source | Occupancy |
|---|---|
| Novasol's projection for us | 70–80% |
| AirDNA, Maastricht market-wide, trailing 12 months — 530 listings, ADR ~€220 | 57% |
| Limburg, July 2025 — the single strongest month of the year | 66% |
Both independent figures sit below the bottom of Novasol's range, and the second is a peak month rather than an average. A well-differentiated niche property can beat a market average — but 70–80% is not corroborated by anything, and the person quoting it is recruiting us onto his platform.
Notice too that the two claims argue against each other: you cannot hold €280 through a February Tuesday and also fill 75% of the year. The flat rate is precisely what makes the occupancy projection implausible. Every number in this document uses 57%.
| Channel | Commission | Net | Exclusive | Keeps our guest |
|---|---|---|---|---|
| Direct | ~2% processing | €275 | — | Yes |
| Vrbo / Expedia | ~8% (5% + 3% card) | €258 | No | Yes |
| Natuurhuisje | 12% incl. BTW | €246 | Best-price clause suspected | Yes |
| Micazu | 12%, only on accepted bookings | €246 | None found | Yes |
| Booking.com | 15–18% | €233 | No | Yes |
| Airbnb | 15.5% host-only (~18–19% incl. VAT) | €228 | No | Post-stay only |
| Novasol | implied 25–40% markup | €225 | Yes | No |
Novasol is the most expensive option on this list and the only one that takes the guest relationship. We would pay OTA-level margin and surrender the direct channel — the worst available combination, and the one currently on the table.
Their agreement reportedly grants Novasol "het exclusieve recht om de vakantiewoning te verhuren". We have not seen it; the public documents are guest terms and the owner-agreement page returns a 404. It has to be requested before anything is signed.
One piece of genuinely good news. Rate parity is dead in the EU. The CJEU ruled in 2024 (Case C-264/23) that both wide and narrow parity clauses fall foul of Article 101(1) TFEU, and Booking.com's designation as a DMA gatekeeper forced it to drop all parity obligations for EEA partners from 2 December 2024. Nothing now stops us pricing lower on our own site than on the platforms. A hybrid — platforms for base occupancy, direct for repeat guests — is legally clear.
And one to avoid outright. An AVROTROS Radar investigation into Belvilla documents exclusivity, margins reaching 70%, dynamic pricing applied without clear owner consent, telesales calling owners up to twenty times a day until 21:00, and a named consumer lawyer alleging the statutory cooling-off period was omitted from contract changes.

The single most valuable question in this project. Axel wrote "de netto vergoeding voor jou" — net compensation for you. Net of what? BTW on lodging became 21% on 1 January 2026. If €225 is inclusive of BTW we must remit, the real figure is €186. Add a Villa Beheer fee and it lands near €150.
Best case €225 clean, 208 nights → €46,800. Worst case → ≈€31,200. A €15,600 a year spread resting on one sentence in one email. Three questions, not one: net of BTW? net of toeristenbelasting? net of Villa Beheer?
Note also what a net-rate deal actually sells us. €225 is per night booked, not guaranteed annually. Novasol absorb price volatility, which is worth something against the €160 nights — but they offered no occupancy guarantee. So the deal hands over 100% of the price upside while we keep 100% of the occupancy risk. Self-managing across Vrbo, Booking, Natuurhuisje and direct blends to roughly €247 a night, about €4,600 a year more, before counting what seasonal pricing adds on top.
Whoever fills the calendar, nobody takes a cut of a bottle of champagne or a pre-heated sauna. The add-on business is the one investment that is correct under every route above, which makes it the least risky thing here and the right thing to build first.
Guests see it three to five days before arrival. That timing is deliberate: anticipation is at its peak, and it is the last moment early enough to still book a chef or a masseur.

Underneath: early check-in and late checkout alone, wine and charcuterie, sauna oils and bath salts, robes guests keep, and partner services on a referral — a chef, a photographer along the Jeker, bikes to the door.
Margins split cleanly. Time costs nothing and sells the most. Physical items cost retail and sell at around two and a half times. Partner services cost nothing and return 20–30%. Everything gets delivered by hand for the first twenty stays, precisely so we learn what people buy before automating any of it.
A useful gap in the market: across every comparable checked, not one publishes a standalone priced menu of extras. This segment sells upsells buried inside all-in "arrangementen". A clean, well-photographed shop sent at the right moment is not a thing our competitors currently do.
We buy the solved parts — calendar sync, platform integration, the booking engine — for about €40 a month. Smoobu and Lodgify both support iDEAL, which matters more than it sounds: our guests are Dutch, Belgian and German, and a card-only checkout quietly loses a large share of them. We build only the part nobody sells properly: the guest experience and the shop inside it.
Weeks 1–2
Per-stay private links, and the logic deciding what is still orderable — champagne needs two hours, a chef needs two days. The same rule decides what is still refundable, so it gets written once and tested hard.
Weeks 3–4
House manual, sauna and jacuzzi guide, the shop with packages first. Dutch and German at launch — our source markets, not English.
Weeks 5–6
iDEAL and Bancontact alongside cards. Both require euro-only pricing, and fulfilment has to survive a webhook arriving twice.
Weeks 7–8
A list of what needs doing and when, a notification when something sells, and the post-stay email inviting a happy guest back directly.
Later
Built on the guest list the app has by then collected. Returning guests get free late checkout and champagne rather than a discount — half the cost to us, and it doesn't teach anyone our rate is negotiable.
Beyond keeping us out of the 60-night regime, five things are trivial to build in now and expensive or impossible to add later.
Non-negotiable
This single line is the €33,000 decision from section 02. The B&B being part of the house and me living above it already satisfies the occupancy half of the test — a full kitchen is the one thing that would undo it by making the space a zelfstandige woning. Kettle, fridge, coffee: fine. Hob, oven and sink as a working kitchen: not fine. Keep the entrance connected to the house too.
Highest value
"Hot when you walk in" is a sellable add-on, an arrival moment and a review driver — and undeliverable without a controller. A smart contactor during first fit costs almost nothing; retrofitting means opening the wall again.
Structural
If the only storage is inside the guest space, restocking mid-stay is impossible and the catalogue shrinks to "late checkout". One or two square metres, a fridge, and a way into the entrance that doesn't cross the bedroom.
Infrastructure
A router upstairs won't reach through a concrete floor. The guest app, the smart lock and the heating control all depend on it — cable in a wall now versus chasing plaster later.
Cheap, high return
Without a submeter there is no way to price the pre-heat add-on or know the real margin on a stay. Designed-in drain access turns the legionella obligation from a chore into five minutes.
Rate-driving
That view, from that tub, is the photograph the listing sells on. Other layout decisions should give way to it. Layered dimmable lighting matters nearly as much — flat ceiling light undoes an expensive fit-out.
Both the B&B route and the housing-stock exemption require the operator to be owner and resident in one person. Frank has the ownership; I have the residency. The governing rule is unforgiving about splitting them.
| Structure | Passes | Why |
|---|---|---|
| Sale to me | Yes | Clean textual match |
| Gift to me | Yes | Passes the test — then fails on tax, below |
| Frank owns, I operate | Doubtful | "blijft wonen" at one week in five; "operate the B&B yourself" |
| Vruchtgebruik / bloot eigendom | No | Splits economic from legal ownership by definition |
| Recht van opstal | No | Splits ownership of structure from land |
| Erfpacht | No | Same structural split |
| Long lease, me as hoofdhuurder | No | A huurder is never an eigenaar |
| VOF / maatschap / BV | No | An entity cannot be hoofdbewoner; also pushes us into Box 1 |
| 50/50 co-ownership | Likely no | The rule's only carve-out is life partners forming one household |
Every clever intermediate structure fails for the same reason: they all split economic from legal ownership, and the rule demands both in one natural person. The regulation writes exactly one exception — "twee personen die in een duurzame relatie één huishouden vormen" — and the fact they needed to write it is the strongest evidence the "100%" is read literally.
The trap: a gift is not the cheap option. Uncle to nephew is the "overige verkrijgers" band — the stranger rate. A €2,769 annual exemption, then 30% to €158,669 and 40% above. On a Jekerdal house that is a six-figure bill. The jubelton was abolished in 2024 and the 18–40 exemption is parent-to-child only. A deliberately low family price doesn't help either — the gap between price and market value is treated as a gift anyway.
So: sale, not gift. Which is gentler than it sounds — 2% overdrachtsbelasting on a main residence, or 0% under the startersvrijstelling if I'm under 35 and it's under €555,000.
Jekerdal and the Jekerkwartier sit among the densest monument areas in Maastricht, and there are two Rijksbeschermde stadsgezichten. If the house is protected, the conversion needs a monumentenvergunning and welstand review on top of everything else. One address lookup answers it, and nobody has done it.
The rules name our area explicitly: a 20% cap on kamerverhuur density, and at least four properties without it between any two that have it. If the block is full, nothing else in this document matters. The gemeente holds the data.
Buildings and liability cover is commonly void if short-stay letting hasn't been declared, and mortgage terms frequently prohibit commercial letting outright. Both are Frank's to check, both are cheap to check now.
A lodging building is a prioritaire installatie: risk analysis by a BRL 6010 certified firm, a written beheersplan, weekly flushing, monthly temperatures, half-yearly sampling. Not a checkbox — a standing obligation with a recurring bill, sitting with the building owner by default.
Unresolved, and resolvable by one email. Nothing gets signed before the answer is in writing.
A four-year letting prohibition from registration of the transfer deed. The family exemption covers first and second degree relatives — uncle to nephew is third, so it likely doesn't reach me. The hospes exemption may, and unusually carries no tourist-letting exclusion.
The B&B is part of the house and I live above it, which is the condition Art. 2.1(1)(b) turns on — so Art. 2.4 doesn't reach us. What remains is a build question, not a legal one: an independent kitchen would make the space a zelfstandige woning and pull it back under the cap regardless of who lives upstairs. Stays resolved as long as the brief says so.
Every add-on assumes someone is upstairs, and the regime in section 02 assumes I actually live here. Both need a deliberate answer rather than one discovered on a Friday night.
Ordered by what unlocks the most, not by what is easiest. The first three cost a phone call each and can each end the project — which is exactly why they come first.
