Which hotel spaces stay outside the modular room package?
Repeated guestrooms can make hotel room floors more repeatable, but they do not make a whole hotel a repeatable package. As of 26.09.2026, Marriott’s modular program lists full guestrooms and bath pods as distinct offerings. Completed Marriott-branded projects show that ground-level public spaces, podiums and connections to site-built work can sit outside the repeated room stack. The boundary varies by project, so the room package needs to be checked against that project’s documents and delivery team. [1] [2] [3] [4]
- As of 26.09.2026, Marriott lists full volumetric guestrooms and bath pods as separate modular categories, with different brand prototypes for each. [1]
- Completed in 2020, AC Marriott Railroad Square used 81 production modules for rooms, corridors and balconies above a concrete ground level containing guest arrival, lobby, meeting and dining spaces. [2]
- At Moxy Oakland, five levels of factory-built rooms sat over two site-built levels; the architect identifies the lower levels as rooms, common space and public tenant space, including a ground-floor lobby and common area. [3] [4]
- The project records identify separate roles for site-built and modular work: ZFA handled engineering of record for Santa Rosa’s site-built portions, while Oakland’s team included a site-built architect, civil engineer, modular factory and modular system designer. [2] [3] [4]
What does Marriott’s modular program list?
Marriott Global Design lists two modular categories: full guestrooms, described as volumetric, and bath pods. As of 26.09.2026, prototype options for full guestrooms are listed for Courtyard, Fairfield, Four Points, SpringHill Suites, StudioRes and TownePlace Suites; bath-pod options are listed for Courtyard, Fairfield Inn and Residence Inn. This is a program menu, not a published scope matrix for every hotel. It does not define who delivers every space outside the guestroom. [1]
What stayed outside the room modules in Santa Rosa?
AC Marriott Railroad Square in Santa Rosa was completed in 2020. The five-storey, 142-room hotel has a concrete ground level and four storeys of volumetric wood modules above it. ZFA Structural Engineers says the 81 production modules included rooms, corridors and balconies, while guest arrival, lobby, meeting and dining spaces are at ground level. ZFA was engineer of record for all site-built portions and worked with the modular design team on site-built attachments and structural and mechanical connections at the podium. The modules therefore included more than bedrooms, while the public ground floor and key interfaces required separate site-built work. [2]
How did Moxy Oakland divide modular and site-built work?
Moxy Oakland used five levels of factory-built rooms above two levels of site-built rooms, common space and public tenant space, according to project architect Lowney Architecture. Lowney locates the lobby and common space at ground level and lists ground-floor retail as a key feature. WoodWorks also describes the two-level concrete podium and records a gym and rooftop bar, but does not locate those uses relative to the modular stack. The documented lower-level public spaces show one project arrangement, not a standard for other hotels. [3] [4]
Which teams handled the interfaces and site work?
The project records show that modular hotel delivery involves distinct design and construction roles around the room stack. At Santa Rosa, ZFA was engineer of record for site-built portions and coordinated attachments and structural and mechanical podium connections with the modular design team. At Oakland, Lowney lists RSP as site-built architect of record and Kimley-Horn as civil engineer; WoodWorks lists Atco Structures & Logistics as modular factory and Prefab Logic as modular system designer. These records identify the team split, but do not assign every site service or utility responsibility. [2] [3] [4]
What should a project team verify?
Mark the module boundary on coordinated plans and the scope matrix, then identify the responsible party and handover point for the podium, ground-floor public areas and podium connections documented in these examples. Also check foundations, vertical circulation, façade and roof interfaces, utility routes and site connections against the actual drawings and contracts; those are general coordination checks, not boundaries established by these project records.
