What we build

Pavilions and exhibition

A pavilion has one property no other building has: the opening date is set by someone else, years in advance, and no extension is available to anyone.

At Expo 2025 Osaka we delivered across seven national pavilions: Portugal, France, Monaco, Oman, Nordic Circle, India and Angola. Each was procured separately by a different participating government, through a different main contractor, to a different architect's design.

Every one of them opened on 13 April 2025.

This is also our clearest demonstration of inbound work. Seven foreign governments needed to build in Japan, in a market none of them knew, to a date that could not move.

What makes these difficult

Interfaces closed before mobilisation

When the date cannot move, the only available strategy is to close interfaces and release long-lead items ahead of the package. Anything left to be resolved on site is a risk with no float behind it.

Materials with no supply route

Pavilion designs specify materials that do not exist as products. Material development, treatment and national fire testing have to fit inside the programme rather than beside it.

Geometry with no repeat unit

Curved and freeform plans remove every shortcut an interior relies on. Setting out runs from a single control point, and components are produced to survey rather than to nominal dimensions.

Where we have done it
