The Montreal Ritz-Carlton was modernized by retaining and restoring its 1912 hotel building while adding a separate residential wing in steel and glass. Architect Provencher_Roy designed the new envelope to echo the old façade’s geometry and rhythm without copying it; upper floors were set back so the historic cornice remained readable from the street. The curtain wall therefore acts as a contemporary counterpoint, not a replacement for the landmark façade.
The work combined restoration, renovation and expansion. It renewed 130 original guest rooms and public areas, inserted luxury residences, and preserved the hotel’s architectural identity while construction continued on a demanding urban site.

What the project changed—and what it deliberately kept
The Ritz-Carlton Montréal opened in 1912, and its Beaux-Arts façades and Adam-style interiors are central to the property’s character. The renovation did not remove those defining elements. Provencher_Roy describes restoring the original building and integrating a new wing, while Pomerleau records preservation of original architectural features alongside room and common-area upgrades.

That figure is the hotel’s own promotional description, not an independently audited project-cost total. It should not be confused with a separate, verified construction budget.
#1 Best Overall
In practical terms, the project had three connected parts:
- Restoration and renewal of the historic hotel, including its original façade.
- Renovation of guest rooms and public spaces.
- Construction of a contemporary wing containing residences and associated envelope work.
Because the addition is new construction, its curtain wall could express a different architectural language. The design goal was to make the old and new portions legible as parts of one complex rather than disguise the addition as historic fabric.
Documented scope and why the numbers differ
Two primary project participants publish different measurements and unit counts. They may be describing different scopes, phases or methods of measuring floor area; the published pages do not reconcile them. Reporting each figure with its source is more accurate than combining them into a single total.

| Source and milestone | Expansion or total area | Rooms or residences | Published year or timing |
|---|---|---|---|
| Provencher_Roy project description | 12,500 m² expansion; 43,000 m² total project area | 130 original hotel rooms renovated; 45 luxury residences | Project page lists 2012 |
| Pomerleau contractor project page | 17,150 m² expansion | 50 new units: 35 deluxe condominiums and 15 condotels | Year built listed as 2014 |
| MAPEI trade publication | Area not stated | Units not stated | Transformation described as starting in January 2013 |
The differences are not evidence that one source is necessarily wrong. A design firm may count a defined addition and the overall project area, while a contractor may report the construction package it built. Unit totals can also change as programs are finalized or can use different definitions for residences and hotel-related units. Keep the attribution attached whenever citing these figures.
The curtain-wall design: a deliberate contrast with a historic reference
Echoing geometry and rhythm
Provencher_Roy says the envelope of the added wing uses steel and glass whose geometry and rhythm recall the 1912 façade. “Echo” is important: the new elevation takes a proportional and repetitive cue from the old one without reproducing its ornament, masonry details or historical styling. The result is intended to read as a contemporary building that belongs to the same composition.
A curtain wall is well suited to that role because it can establish a consistent grid across several floors while remaining visually lighter than a load-bearing masonry wall. The sources identify the material strategy as steel and glass, but they do not publish mullion dimensions, glass make-up, thermal values, anchorage details or a named curtain-wall manufacturer. Those technical specifications should not be inferred from the project photographs or from suppliers documented for other parts of the work.
Setting the upper floors back
The architect also states that the added upper stories were set back from the façade. This preserves the original cornice line, the strong horizontal termination that helps viewers read the 1912 building. From the street, the setback creates a visual pause between the heritage volume and the taller contemporary construction. It limits the apparent height of the addition at the historic frontage without pretending that the new wing is old.

The expansion integrated a residential program rather than simply adding hotel bedrooms. Provencher_Roy lists 45 luxury residences; Pomerleau lists 50 new units divided into 35 deluxe condominiums and 15 condotels. That program explains why the new wing needed its own façade expression and generous openings. The curtain wall identifies the residential component while the restored hotel remains recognizable as the original institution.

How the new wing protects the old building’s presence
The project’s heritage strategy can be understood through three coordinated moves rather than a choice between competing envelope systems.
- Keep the original façade. The historic elevations remain the visual reference and were restored as part of the broader renovation.
- Use a contemporary steel-and-glass grid. The new wing acknowledges the old façade’s spacing and order while using unmistakably modern materials.
- Step back the upper levels. The setback protects the cornice line and keeps the original building’s silhouette dominant at street level.
These moves answer the central design problem identified by the architect: adding substantial floor area without mimicking or overshadowing the landmark. Claude Provencher, senior partner at Provencher Roy, described the assignment as “a major contemporary updating of a heritage building.” He also summarized the challenge as giving “…the hundred-year-old hotel with a new face without altering its personality.” The wording captures the distinction between updating performance and program and changing the building’s identity.
Restoration, interiors and the envelope were separate scopes
Not every product documented on the project belongs to the curtain wall. Fenêtres MQ says hundreds of its windows are on the historic façade and that it designed nine-foot mahogany folding doors for the residences. Those details support a precise supplier role: historic-façade windows and residence doors. The source does not say that Fenêtres MQ supplied the steel-and-glass curtain wall.
Recommended Free Tools
MAPEI documents renovation materials used for slab repair and tile-setting applications. These products relate to repairing and finishing the building, not to the curtain-wall assembly. Keeping the scopes separate matters when evaluating how the project was built: a tile adhesive, a repaired slab and a folding mahogany door solve different problems from a glazed, multi-storey enclosure.
The interior work was equally important to continuity. The project renewed rooms and common spaces while retaining the Adam-style character associated with the hotel. A contemporary exterior addition could therefore coexist with updated services and finishes inside the historic volume without requiring a wholesale stylistic replacement.
Construction in a busy urban setting
Pomerleau describes work on a high-traffic urban site, with preservation of original features, renovation of rooms and common areas, and construction of the new expansion occurring as one project. The available project pages do not publish a complete phasing schedule, closure plan or logistics diagram. They do establish that the work involved coordinating restoration and new construction where access, staging and protection of existing fabric were constrained by the city location.
MAPEI’s trade publication places the start of the transformation in January 2013, while Provencher_Roy lists 2012 for the project and Pomerleau lists 2014 as the year built. Those markers likely refer to different milestones—design or project listing, construction activity, and completion or contractor reporting—but the sources do not provide a single reconciled schedule. Use the dates as source-specific milestones, not as a definitive start-to-finish timeline.

Define the element that must remain legible
For this hotel, the cornice line and the original façade were the critical visual references. A comparable retrofit should identify its own non-negotiable elements before selecting an addition’s cladding or glazing. That may be a roof profile, a masonry bay rhythm, a tower cap or a significant entrance sequence.
Best Value
Match order, not ornament
The architect’s approach demonstrates a useful middle path between imitation and disregard. Repeating a façade’s broad geometry and rhythm can establish visual conversation; copying decorative details can produce a false historical skin, while ignoring the old building can make the addition appear hostile. The Montreal wing uses the former strategy.
Use setbacks to control scale
Stepping upper floors away from a heritage frontage can preserve important sightlines and reduce apparent bulk. It does not eliminate the addition’s height, but it places that height where it is less likely to overwhelm the original cornice and street wall.
Report project data by source
The conflicting area and unit figures are a reminder to state who measured what. A reliable case study keeps Provencher_Roy’s 12,500 m² expansion and 45 residences distinct from Pomerleau’s 17,150 m² expansion and 50-unit program. It also identifies whether a cost is an owner’s current description or an audited figure.
Separate heritage repairs from new-envelope specifications
Window restoration, mahogany folding doors, slab repairs, tile setting and curtain-wall construction can all appear in the same renovation, but they have different performance criteria and suppliers. Procurement and commissioning documents should identify each assembly independently so that warranties, maintenance responsibilities and heritage approvals are not blurred.
Why the Montreal solution remains relevant
Historic hotels often need more rooms, residences, updated services and contemporary code performance while their public identity depends on an older façade. The Ritz-Carlton Montréal shows how an addition can deliver new area without claiming to be part of the 1912 fabric. Its steel-and-glass curtain wall provides a clear contemporary layer; the restored façade, preserved cornice and retained interiors keep the original hotel readable.
The project is best understood as an exercise in controlled contrast. The old building supplies the proportions, rhythm and civic presence. The new wing supplies additional floor area and a distinct residential address. Because the two roles are coordinated rather than conflated, the modernization updates the property without erasing the landmark that made the intervention worth doing.
