Owner-side hospitality capex advisory.
Portier underwrites the commercial case for hotel renovation before design decisions become irreversible.
A renovation is not a design question first.
It is a commercial decision expressed through space.
01
The Owner’s Table — where the commercial case is framed before design begins.
02
Arrival Sequence — the first 90 seconds as spatial evidence.
03
Commercial Design Brief — measurable requirements for the design team.
04
Bar After 21:00 — atmosphere as a commercial condition.
05
Spatial Premium — the question of how much ADR the space earns.
Service model
Four stages, one commercial intent.
Methodology · Step 01 / 05
Measure first
Every engagement begins with a revenue model, not a mood board. The question is not whether a space can be made beautiful. The question is whether the intervention is commercially justified.
Step 01
Measure first
Every engagement begins with a revenue model, not a mood board. The question is not whether a space can be made beautiful. The question is whether the intervention is commercially justified.
Step 02
Read the arrival sequence
We examine how threshold, sightline, circulation, and atmosphere shape commercial performance.
Step 03
Define the brief
The commercial design brief converts the investment case into guest behaviours, zone KPIs, priorities, and acceptance criteria.
Step 04
Test the atmosphere
A bar, lobby, or restaurant is evaluated not only by how it looks, but by what it enables guests to do.
Step 05
Hold the commercial intent
During design development, Portier reviews decisions against the approved investment case and records where commercial intent is at risk.

Five Questions Before a Hotel Renovation Is Approved
A renovation proposal should arrive at investment committee with more than a concept, a capex number, and an assumed ADR uplift. These five questions expose whether the commercial case is ready.

What a Design Brief Actually Is
Most design briefs in luxury hospitality are documents of aspiration. They describe what a space should feel like. They do not describe what a space should do — and that distinction costs money.

The Spatial Premium Problem
Luxury hotels are sold on spatial experience. The rates are justified, in large part, by what the space feels like. And yet very few operators have a rigorous answer to the question: how much of our ADR is the space earning?
