LaPour Partners is advancing plans for a JW Marriott Downtown Phoenix that would convert a vacant 19-story office tower at Arizona Center into a 340-room luxury urban resort. The project is not bookable yet, but it changes how convention and leisure planners should track downtown Phoenix lodging inventory.
If you are already building 2027 to 2029 Phoenix itineraries around the convention campus, Chase Field, Footprint Center, or a walkable downtown stay, treat this as a named future brand option rather than a confirmed open date. The developer still lists the year as coming soon, so do not lock group blocks on an assumed opening night.
- What is planned: A 340-room JW Marriott adaptive reuse at Arizona Center in downtown Phoenix.
- Building: 19-story, about 351,600 square foot former Class A office tower built in 1989.
- Positioning: Luxury urban resort with pool, spa, fitness, signature restaurant, and club lounge plans.
- Event floors: Upper-level meeting and banquet space on floors 18 and 19 with city views.
- Status: Planning stage and not yet bookable; LaPour lists the year as coming soon.
What LaPour published about the project
According to the LaPour project page for JW Marriott Phoenix, One Arizona Center is an adaptive reuse conversion of a 19-story, 351,600 square foot Class A office tower into a luxury urban resort hotel in downtown Phoenix. The page places the property inside Arizona Center, a mixed-use destination with office, retail, dining, entertainment, and a landscaped courtyard.
LaPour lists 340 keys, a JW Marriott signature development, and a downtown Phoenix at Arizona Center submarket. The published year field is “Coming Soon,” which is the clean status line for travelers. No official public booking window appears on that page.
The developer describes an urban resort layout with a ground-level pool overlooking a two-acre park-like setting, average room sizes exceeding 500 square feet, expansive glass lines, and floor-to-floor heights of about 12 feet 6 inches. Upper-level meeting and event spaces on the 18th and 19th floors are framed as a business and social gathering draw with panoramic views.
Amenities listed on the same project page include a spa, fitness center, signature restaurant, banquet and meeting facilities, and an exclusive club lounge. Location language stresses walking distance to major employment hubs, healthcare and educational centers, and the Phoenix Convention Center.
What independent lodging coverage adds
LODGING Magazine’s report on the LaPour announcement restates the adaptive reuse concept and the 340-room JW Marriott plan for the Arizona Center office tower. The trade account also quotes LaPour founder Jeff LaPour on downtown Phoenix demand and the scarcity of luxury hospitality in the downtown business district.
That independent write-up confirms the market story without turning a planning-stage project into an open hotel. It also notes the project remains in the planning stages, which matches the “Coming Soon” field on the developer site.
Local business reporting has circulated an expected 2029 opening year. Treat that as secondary market reporting unless LaPour or Marriott publish a firm opening date on an owned page. For traveler decisions, the binding facts today are the brand, room count, Arizona Center location, and planning-stage status.
Why downtown Phoenix inventory timing matters
A named JW Marriott inside Arizona Center would sit next to the convention campus and major sports and entertainment venues. Convention planners who already stretch peak room blocks across multiple brands should watch for future group-sales availability, but they should not assume inventory exists yet.
Leisure travelers comparing resort brands in metro Phoenix still have current bookable JW options outside this conversion. This downtown project is a future urban-resort concept, not a same-week replacement for an open desert resort stay.
Office-to-hotel conversions can also face design, financing, and permit timing risk. Until construction milestones and a public open date land, the traveler action is monitoring and itinerary flexibility, not prepaid deposits on a phantom room night.
How to plan Phoenix trips while the hotel remains unbookable
Keep 2026 and near-term Phoenix stays on currently open hotels and short-term inventory. Use this project only as a watch item for later multi-year plans that need a downtown luxury brand near the convention center.
If your trip is family-oriented in the wider metro area, pair the downtown lodging watch with existing destination pages that already help sequence the visit. Deep Arrival’s Phoenix RV parks and campgrounds guide supports land-based overnight planning while hotel inventory is still shifting.
Travelers combining Phoenix with Scottsdale family lodging can also use the Great Wolf Lodge Scottsdale planning guide for a currently open metro stay product. That is not a substitute for a future JW Marriott room, but it is a real booking path while the Arizona Center conversion is still in planning.
Also separate brand identity carefully. Metro Phoenix already has open JW Marriott resorts with established guest operations. A future downtown conversion does not automatically share those resort amenities, shuttle patterns, or golf packages. Compare product to product only after this tower publishes its own room categories and public rate calendar.
Group planners should keep contingency hotels even after a soft open is announced. Adaptive reuse projects sometimes open in phases, with meeting floors or food outlets lagging guest rooms. A first-night celebration is not the same as full program readiness for a 1,000-person general session.
For a wider Arizona drive day after a downtown event, the Sedona things-to-do guide remains a useful independent day-trip planner once lodging for the Phoenix nights is locked.
What the conversion design implies for guests
LaPour highlights oversized guest-room layouts and high floor-to-floor heights as reasons the existing tower is unusual among office conversion candidates. If those dimensions survive design development, the product pitch is larger rooms and more natural light than a typical downtown box hotel.
Upper-floor banquet and meeting space is central to the demand story. A JW brand with panoramic 18th and 19th floor event rooms would compete for association dinners, corporate offsites, and wedding programs that currently leave downtown for resort campuses.
The ground-level pool facing a landscaped courtyard is meant to make the property feel like an urban resort rather than a pure convention box. That design language matters for leisure weekends, but only after the hotel is open and rateable.
Until construction photos and brand renderings show final public spaces, treat amenity lists as the developer program, not a verified guest experience. Programs can change between planning announcement and opening day.
| If you… | What to do |
|---|---|
| Need rooms this year or next season | Book open Phoenix inventory now; do not wait on this conversion. |
| Plan a multi-year convention return | Watch LaPour and Marriott channels for a dated open window before changing blocks. |
| Want a JW brand in metro Phoenix now | Use currently open JW properties rather than the planned downtown tower. |
| Heard a 2029 opening rumor | Treat it as secondary reporting until the developer or brand confirms a date. |
| Need a family metro stay today | Use open Scottsdale or Phoenix lodging products already on sale. |
- Firm open date: An owned LaPour or Marriott date replaces the current coming-soon status.
- Construction start: Visible work at Arizona Center would move the project from concept toward supply.
- Group sales: Future RFPs should wait for brand-managed inventory, not speculative room counts alone.
- Alternate brands nearby: Downtown competitive supply can still change before this tower opens.
The practical traveler takeaway is simple. Downtown Phoenix is getting a named JW Marriott plan for a 340-room adaptive reuse at Arizona Center, but the hotel is not open and not bookable. Plan current trips on real inventory, and treat any opening year beyond LaPour’s coming-soon field as provisional until an official date is published.

No. LaPour lists the project year as coming soon, and the conversion remains in the planning stages.
How many rooms are planned?
LaPour’s project page lists 340 keys for the JW Marriott Phoenix conversion at Arizona Center.
Where would the hotel sit?
Inside Arizona Center in downtown Phoenix, in a 19-story former office tower near the convention campus.
Is an opening year confirmed by the developer?
The owned project page does not publish a firm year. Local business reporting has discussed 2029, but that remains secondary until confirmed.
What should convention planners do today?
Keep current blocks on open hotels and only reassign after a brand-managed open date and inventory path exist.
