Business case · 8 August 2026
Sixty square metres below the house, with a sauna, a jacuzzi and the Jeker outside the window. What it earns, and what still needs answering before anything is signed.
Frank owns the house. I live in the attic and would run the B&B in the basement as manager. Nothing transfers. I take out manager's remuneration plus the add-on business in my own name. Section 10 covers it; put it on paper.
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, so every decision in this document is still live. Some stop being live soon.
I live in the building. Nobody competing with us can put champagne in a guest's hand in ninety seconds.
Remote hosts cannot chill a bottle, lay a breakfast or heat a sauna from across town. It is why section 07 is worth building whoever fills the calendar.
Maastricht caps tourist letting of a self-contained dwelling at 60 nights a year. It does not apply to us.
| 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 names only subsection (a), self-contained dwellings. We are subsection (b), and we meet its test on every limb:
| Requirement | Us | Met |
|---|---|---|
| Not a zelfstandige woning — no own facilities | No separate address, no separate front door | Yes |
| "waarbij de hoofdbewoner in het overige deel verblijft" | The basement of the house I live in | Yes |
| Maximum four weeks per stay | Two-night couples bookings | Yes |
The building already is what it needs to be. Falling under the cap would take a kitchen and a separate entrance, which itself requires a woningsplitsing permit.
One guardrail, for the aannemer. No independent kitchen, no separate street entrance. Kettle, fridge and coffee are fine, and all a wellness guest wants. One line in the fit-out brief (section 09).
Novasol propose €225 net per night against a guest price of "+/- €280", flat all year, minimum two nights. The closest real comparable is Dormio Resort Maastricht's "Aqua Wellness": 53 m², two people, private outdoor sauna and hot tub. I read its prices live from the booking engine, all-in: cleaning, made beds, towels, tourist tax for two, booking fee. Like for like against €280.
Observed nightly rates, Aug 2026 – Feb 2027, against a flat €280.
| Check-in | Type | Nights | €/night |
|---|
The annual peak is not summer. 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.
€280 flat is the market's blended average presented as its constant. February midweek the market is €212, so a flat rate overprices us on the nights that need filling. Peak weekends reach €382, and under a net-rate deal we see none 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 publishes the peaks a year ahead: 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, not an average. A differentiated niche property can beat the market. But nothing corroborates 70–80%, and the person quoting it is recruiting us onto his platform.
You cannot hold €280 through a February Tuesday and fill 75% of the year. The two claims argue against each other. 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 here and the only one that takes the guest relationship. OTA-level margin and no direct channel: the worst combination available, and the one 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. Request it before anything is signed.
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 DMA gatekeeper designation forced it to drop all parity obligations for EEA partners from 2 December 2024. So we can price lower on our own site: platforms for base occupancy, direct for repeat guests.
Avoid Belvilla. An AVROTROS Radar investigation 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.
Section 10 makes the nights Frank's revenue and the add-ons mine. Two ledgers; combining them would flatter both.
| Line | Amount |
|---|---|
| Nightly income — 208 nights at €225 net | €46,800 |
| Energy — sauna, jacuzzi, heating | −€2,800 |
| Linen, consumables, welcome items | −€1,300 |
| Insurance, maintenance, reserve | −€1,800 |
| Legionella beheersplan + sampling (BRL 6010, recurring) | not yet quoted |
| Villa Beheer servicing — basis unresolved | −€0 to −€9,400 |
| My remuneration as manager | to be agreed |
| Before servicing, manager fee and tax | €40,900 |
| Line | Amount |
|---|---|
| Remuneration as manager (deductible for Frank, income for me) | to be agreed |
| Add-on business, own KVK — after cost of goods | €3,650 |
| ~83 stays at ~€80 attach, ~55% blended margin | — |
| Mine outright, before the manager fee | €3,650 |
Net of what? Axel wrote "de netto vergoeding voor jou", net compensation for you. BTW on lodging became 21% on 1 January 2026. If €225 includes 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: net of BTW? Net of toeristenbelasting? Net of Villa Beheer?
€225 is per night booked, not guaranteed annually. Novasol absorb price volatility, worth something against the €160 nights, but offered no occupancy guarantee: they take 100% of the price upside, 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 seasonal pricing.
Nobody takes a cut of a bottle of champagne or a pre-heated sauna. The add-on business is correct under every route above, so build it first. Under section 10 it runs on my own KVK registration, so it is mine outright.
Guests see it three to five days before arrival. Anticipation peaks there, and it is still early enough to 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.
Time costs nothing and sells the most. Physical items sell at around two and a half times retail. Partner services cost nothing and return 20–30%. Deliver by hand for the first twenty stays, so we learn what people buy before automating.
A gap in the market: across every comparable checked, not one publishes a standalone priced menu of extras. The segment buries upsells inside all-in "arrangementen". Nobody sends a photographed shop at the right moment.
We buy the solved parts (calendar sync, platform integration, booking engine) for about €40 a month. Smoobu and Lodgify both support iDEAL; our guests are Dutch, Belgian and German, and card-only checkout loses a large share of them. We build only what nobody sells properly: the guest experience and the shop inside it.
Weeks 1–2
Per-stay private links, plus 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 write it once and test it hard.
Weeks 3–4
House manual, sauna and jacuzzi guide, the shop with packages first. Dutch and German at launch, not English: those are our source markets.
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 collected by then. Returning guests get free late checkout and champagne instead of a discount: half the cost to us, and it doesn't teach anyone our rate is negotiable.
Six things are cheap now and expensive or impossible later.
Non-negotiable
The guardrail from section 02. A working kitchen plus a separate entrance is the only way back under the 60-night cap. Kettle, fridge, coffee: fine. Hob, oven and plumbed sink: not fine. Keep the entrance connected to the house.
Highest value
"Hot when you walk in" is a sellable add-on and a review driver, 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, or chase plaster later.
Cheap, high return
Without a submeter we cannot price the pre-heat add-on or know the real margin on a stay. Designed-in drain access turns the legionella obligation into five minutes.
Rate-driving
That view, from that tub, is the photograph the listing sells on. Other layout decisions give way to it. Layered dimmable lighting matters nearly as much; flat ceiling light undoes an expensive fit-out.
Frank owns the house. I live in it and manage it. Nothing transfers: no sale, no gift, no mortgage.
Two things follow. The tax structure is cheap to set up now and expensive to unwind later.
Licensing: resolved from the regulations. The gemeente's English summary page says the operator must be main occupant and owner. The binding texts say otherwise.
Huisvestingsverordening Art. 2.3: "Aanvragen voor een registratienummer … worden gedaan door degene die een woning of wooneenheid aanbiedt voor toeristische verhuur". The word is aanbieder, not eigenaar.
Art. 2.1(1)(b): requires only that the hoofdbewoner lives in the remaining part.
Bestemmingsplan Art. 5.8 (kamerverhuur): keys on "kamerverhuurder ter plaatse het hoofdverblijf heeft" — residence, not ownership. Max 2 rooms, minimum 20 m² each.
Ownership surfaces in one place: the guesthouse provision, Art. 5.5. Art. 5.6.6 permits deviation for non-resident operators, subject to parking standards and neighbourhood impact.
So I qualify as I am. What remains: whether the gemeente files a wellness B&B under 5.5 or 5.8. If 5.5, there is a named deviation route. A scoping conversation.
The tax structure. If Frank owns the dwelling and the nightly income is legally his, handing the surplus to me could read as a gift, and uncle to nephew is the 30% band. Two fixes, and they compose:
1. I am remunerated as manager: a deductible expense for Frank, ordinary income for me. A cost of his business rather than a transfer of his money.
2. The add-on business is mine outright: my own KVK registration, my own Stripe account, my own invoices to guests. That revenue is mine by construction, with no attribution question and no gift exposure.
The split: Frank's dwelling earns the nights, my business earns the extras.
Live first, resolved last. Four of the nine were open at the start of the week and are now closed.
The rules name our area: 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 here matters. The gemeente holds the data and nobody has asked. Our street is large detached villas, so this is likely fine. Likely is not checked.
Buildings and liability cover is commonly void if short-stay letting hasn't been declared, and mortgage terms often prohibit commercial letting outright. Frank's to check, and cheap to check now.
Net of BTW? Of toeristenbelasting? Of Villa Beheer? Unresolved, and resolvable by one email. Nothing gets signed before the answer is in writing.
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. A standing obligation with a recurring bill, sitting with the building owner by default. Still unquoted.
Every add-on assumes someone is upstairs, and the regime in section 02 rests on my living here. Decide the cover in advance, not on a Friday night.
No separate address, no separate front door, so not a zelfstandige woning and Art. 2.4 doesn't reach us. Stays resolved as long as the fit-out brief bars an independent kitchen.
Read from the binding texts rather than the summary page. Art. 2.3 keys the registratienummer to "degene die aanbiedt"; Art. 2.1(1)(b) and bestemmingsplan Art. 5.8 key on hoofdbewoner / hoofdverblijf. Full citations in section 10. I qualify as manager and resident, with no transfer.
Checked. Three houses further along the street are listed monuments; ours is not. The 1996 Rijksbeschermd gezicht covers Wyck, across the Maas, and the 1982 designation covers the historic centre. A 1941 villa in Buitenwijk Zuidwest sits outside both. Worth one line in writing.
The rule only bites below a WOZ ceiling of roughly €402,000, and this house is several times that. Moot in any case now that nothing transfers.
Only one item here can still end the project. It is the first one.
