The Spreadsheet Draws the Building: What Expo Real Reveals About Who Really Designs Our Cities

When Expo Real fills Messe München from 5–7 October 2026 — Europe's largest property fair, with 1,856 exhibitors and more than 40,000 visitors — you will hear a great deal about design: renderings, placemaking, "iconic" towers. What you will rarely hear is the uncomfortable truth the whole event is built on. By the time any of those buildings reached an architect, their most important design decisions had already been made. Not in a studio — in a spreadsheet.

Every large building begins life as a development pro forma: a financial model projecting what the project will cost, earn and be worth. Crucially, this happens at the very start, at the concept and feasibility stage — before site design, before entitlements, before an architect is engaged. And the model does not merely decide whether to build; it decides what to build. As one primer puts it bluntly, the pro forma is where you decide "how big (or small) and how fancy (or simple)" a project will be. The assumptions in that model determine what gets built.

Look closely and the things we experience as architecture turn out to be mostly outputs of that math. The floor-plate depth — how far a desk sits from a window — is set by the economics of leasable area, not by daylight. The floor-to-floor height, which governs how generous a room feels, gets squeezed to fit more storeys under a height limit. The massing is driven by Floor Area Ratio and the cost of building tall. The use-mix, the column grid, the ceiling — largely resolved in the model. The architect is then handed an envelope and asked to make it beautiful.

This is the built environment's concept phase, and it is the purest example we cover of the decision being made upstream by someone who would never call themselves a designer. It is also why so many buildings feel the same: when the operative brief is "maximise leasable area within the code," the answers converge — and styling applied afterwards cannot undo a shape optimised for a yield curve. Critics have a sharper word for it, the financialization of architecture, and warn that design has become precarious, overshadowed by the model. Capital wants low cost and high return; architecture has traditionally defined itself as the service that resists exactly that.

But here is the twist that makes Expo Real worth watching rather than lamenting. The spreadsheet is not the enemy of good design — it is simply where good design now has to be argued. And there is hard evidence that design belongs in the model on its own terms: studies find that design-led properties command a 15–25% premium over generic inventory. That premium is a design decision expressed in the only language a pro forma understands. The smartest developers already know it: they don't treat quality as a cost to minimise after the model runs, they put it in as a value to capture — better daylight, generous floor-to-floors, a plan people actually want to be in — and let the premium justify itself.

That is the real lesson beneath the deal-making. The decisive move is not choosing a façade; it is deciding, at the feasibility stage, what the building is for and what quality is worth — because everything downstream inherits that decision and cannot reverse it. You cannot design your way out of a pro forma that valued only square footage. You can only design your way in, by getting into the model early enough to change what it optimises for.

Expo Real is, in that sense, the most honest design event of the year. It drops the pretence that buildings begin with a sketch and admits they begin with an assumption. The people shaping our skylines most decisively are the ones building the models — and the opportunity is to make design one of those assumptions, not an expense line bolted on at the end.

Deciding what a thing is worth being — before the constraints are locked — is exactly the moment we work in at Depix.
