Reuse
Level R · +164'-0"-
5.01
What the Floor Plate Actually Allows
A hotel floor plate was optimised for a specific bay-and-corridor logic — this explainer maps which reuse programmes fit that geometry naturally and which fight it, using floor-plate dimensions common across the 1920s–1960s building stock.
-
5.02
The Ballroom That Would Not Subdivide
Long-span ballroom structures resist subdivision because their structural system was designed around the open span — this piece looks at several reuse projects where the ballroom defeated the programme, and asks whether the right answer is to stop trying.
-
5.03
Hotel to Housing: Where the Numbers Break
Converting a downtown hotel to residential use is frequently proposed and frequently stalled — this piece identifies the specific building-code and structural gaps that make it harder than it looks, without pretending the economics are simple.
-
5.04
Preservation and Reuse Are Not the Same Argument
An argument piece clarifying the distinction between historic preservation (keep it as-found) and adaptive reuse (keep it alive), using hotel buildings where these two positions have come into direct conflict over the lobby or ballroom.
-
5.05
The Atrium Conversion Always Costs More
Cutting an atrium into an existing hotel block during reuse is a recurring proposal that routinely blows the budget — a walk-through of why: the structural transfer required, the egress implications, and the HVAC load the void creates.
-
5.06
Three Reuse Failures Worth Studying
Three hotel reuse projects — not named to avoid factual invention — where the programme failed not from lack of money but from a misreading of what the building was structurally willing to become; each failure illuminates a different class of mistake.
Ballrooms & Banqueting
Level M · +22'-0"-
3.01
Spanning the Ballroom
Long-span ballroom structures in city hotels — how engineers cleared fifty to eighty feet without intermediate columns, the structural systems used across different eras, and why the ballroom floor is often the most complex slab in the building.
-
3.02
The Folding Wall's Broken Promise
Operable partition walls promised infinite flexibility and routinely delivered acoustical failure — this piece explains why folding panels fall short.
-
3.03
Setting a Room for Five Hundred
A walk-through of the physical sequence involved in turning an empty ballroom into a dinner for five hundred — the dock call, the cart routes, the linen sequence, the light plot — treating it as a logistical and spatial problem, not an event-planning one.
-
3.04
The Grid Above the Chandelier
Above the decorative ballroom ceiling there is almost always a structural grid carrying rigging points, catwalk access, and HVAC — a short explainer on what that plenum contains and why it controls what the room below can become.
The Lobby
Level G · ±0'-0"-
2.01
Terrazzo Reads the Room
Hotel lobby terrazzo floors are not ornament — they are a zoning document in aggregate and cement, directing traffic, marking threshold and hierarchy. This piece decodes several lobby floors as architectural drawings you walk across.
-
2.02
Why the Columns Are Where They Are
An explainer on the structural logic behind lobby column grids in pre-war and early postwar hotels — how the bay size was set by the guest room above, and what that means for the lobby's apparent generosity or awkwardness.
-
2.03
The Mezzanine Nobody Uses Correctly
Mezzanine levels in hotel lobbies were designed for a specific social function that has mostly dissolved — this piece argues that what survives is usually misread by renovators and proposes what the level was actually for.
-
2.04
When the Lobby Ate the Building
A comparison of the enclosed lobby typology against the hotel atrium introduced in the 1960s and expanded through the 1980s — what the atrium solved structurally and acoustically, and what the original lobby did better.
-
2.05
The Front Desk Was Never Centred
A short piece on the siting of the front desk within the lobby — why it is almost never on the axis, what sightlines it was designed to command, and how that asymmetry tells you something about security and social hierarchy baked into the plan.
The Motor-Hotel Era
Level S · SITE-
4.01
When the Canopy Became the Front Door
The porte-cochère was a carriage detail in the grand hotel tradition; the motor hotel made it the building's primary organisational element — this piece traces that shift and its structural consequences for how the building meets the street.
-
4.02
Inside Out: The Corridor Decision
A direct comparison of exterior-corridor and interior-corridor motor hotel plans — what each costs to build, heat, and maintain, and why the same chain sometimes built both within miles of each other.
-
4.03
The Package That Built a Thousand Identical Hotels
Mid-century franchise hotel chains supplied franchisees with a structural and finish package — this explainer unpacks what was in it, how much was truly standardised, and why the buildings still look related despite regional contractors.
-
4.04
The Sign That Named the Building
Roadside hotel signage was an architectural element and a zoning battleground — this piece covers the structural anchoring of large neon road signs, the ordinance fights that removed them, and why their absence changed how the buildings read from the street.
-
4.05
What the Motor Inn Got Right
An argument piece: the stripped-back motor hotel solved several problems the grand hotel never did — direct room access, parking integration, legible wayfinding — and dismissing it as architecture is a way of not looking at it carefully.
Back of House
Level B1 · −14'-0"-
1.01
The Corridor That Holds the Building Up
The service corridor in a large hotel is not a leftover space but a structural and logistical spine — this piece traces how it is sized, routed, and why its dimensions constrain everything above it. An argument for reading the back passage as the building's real architecture.
-
1.02
Every Few Floors, a Machine Room
Tall hotels require intermediate mechanical floors — this explainer maps how they are positioned, what they contain, and why their ceiling heights show up as a blank band on the building's facade. Covers the engineering logic without assuming a reader who can read an MEP drawing.
-
1.03
The Linen Room Is Never Where You Expect It
A walk-through of how a hotel's linen distribution system is laid out across a typical tower floor — the chute locations, the housekeeping closet sizing, and the recurring mistake that forces a morning cart jam. Practical and specific.
-
1.04
Freight In, Waste Out
The receiving dock and the service elevator core are the building's circulatory system — this comparison piece sets the grand hotel's logistics plan against the motor-hotel's simpler solution and explains what was lost when the dock moved to the basement.
-
1.05
The Room Behind the Desk
A short atmospheric piece on the night-audit office — its physical position relative to the front desk, the paper trails it once generated, and what its spatial logic reveals about how trust was built into hotel architecture before surveillance technology.
