The brief
CoreWeave brings distributed teams together for onsites — a few days when people who normally work from different cities are in one room, and the room has to look like the company rather than like a booked conference floor. The décor has to carry the brand blue without a print budget, give the day a photo backdrop people will actually stand in front of, and be gone again by the time the floor goes back to being an office. Across three installations we have built to that brief.
What we installed
- A paired arched-panel backdrop for the 2025 Annual CFO Team Onsite: a navy panel reading "Building the Future of CoreWeave Together" beside a white panel carrying the CoreWeave mark, with organic garlands running up the outer edge of each and over the crown.
- Garlands built in CoreWeave's own blues — navy, slate and mid-blue against white, with silver chrome worked through the run so the piece catches the light off a glass wall instead of going flat against it.
- Freestanding balloon bouquets on weighted bases flanking the backdrop and the welcome sign, sized to read from across the floor without narrowing the walking route between them.
- A silver sequin shimmer wall framed with a navy, black and silver chrome garland for a winter party — the garland carried up one side, across the top and part-way down the other, so the frame reads as asymmetric rather than as an arch.
- Table dressing for the same winter party: a snowflake runner down the length of the communal table with low pieces that clear sightlines across it, lit by blue uplighting run along the window wall.
- A white lit tree centrepiece set at the head of the table, kept low and narrow so it framed the room rather than blocking the view down it.
Getting it installed
Built on an occupied office floor
- These are working floors with desks, a kitchen and a meeting room in use, not a hired event space — so the install runs to the building's day, and the piece is finished before the floor fills rather than assembled around people.
Backdrops and shimmer walls arrive as hardware and are dressed in place
- The panels and the sequin wall are freestanding structures carried in flat and stood up on site, then garlanded once they are square and stable; nothing is built at height over a table that is already laid.
Weighted, not taped, on hard flooring
- Polished concrete and sealed floors take no adhesive and give no anchor, so bouquets and column bases are weighted and the backdrop frames are ballasted at the feet.
Routes kept open
- The backdrop pair and its bouquets are set against a wall or a window line with the walking route left clear in front, because the whole point of a photo backdrop is that a queue can form at it without blocking the floor.
Daylight planned for, not fought
- The floor here is glass on two sides, so the garlands carry chrome and the darker navies deliberately — a pale-only palette bleaches out against a window and photographs badly, which is the failure mode these rooms produce.
Teardown included
- Pieces come down after the event rather than being left for the office to deal with on Monday.
CoreWeave installations
Questions about this install
Can you install balloon décor in an office that is still being used that day?
Yes — Balloon Bay installs on occupied office floors regularly, and the work runs to the building's day rather than the other way round. Pieces are built in place and finished before the floor fills, freestanding backdrops are stood up and dressed on site rather than assembled over furniture already in use, and the walking routes stay open throughout. The CoreWeave onsite and winter-party installs were both built this way.
Can balloon décor be matched to a company's brand colours?
Yes. Balloon Bay specifies latex and chrome from a company's own palette rather than from a stock party range — the CoreWeave installations are built in the company's navy, slate and mid-blue against white, with silver chrome worked through the run. Send a brand guide or a hex value with the quote request and the colours are specified from it rather than matched by eye.
How do you anchor balloon décor on polished concrete where nothing can be taped?
Weights and ballast, not adhesive. Polished concrete and sealed office floors take no tape and offer no anchor point, so Balloon Bay sets freestanding bouquets and column bases on weighted plates and ballasts backdrop frames at the feet. This is how the CoreWeave backdrop pair and its flanking bouquets were installed, and it is why nothing on those floors is fixed to the building.
Can you decorate a company onsite or all-hands rather than a holiday party?
Yes, and it is a large share of the corporate work Balloon Bay does. An onsite wants a branded backdrop people will photograph themselves in front of, a welcome point that reads from across the floor, and nothing that narrows the room — a different brief from a party. Balloon Bay built the backdrop pair and welcome bouquets for CoreWeave's 2025 Annual CFO Team Onsite to exactly that shape.
