ODA Skyscraper Nears Completion Atop Rotterdam’s Historic Post Office

The article spotlights Post, a near-complete 150-metre-tall, 43-storey skyscraper in Rotterdam. The project reimagines the city’s historic post office through adaptive reuse.

Designed by New York firm ODA and developed for Omnam Group, this project transforms the 1916 landmark on Coolsingel into a mixed-use complex. It features a hotel within the tower, a refreshed historic fabric, and a revitalized public realm around a vaulted plinth and courtyard.

Project Overview

The transformation is a bold blend of heritage and modern urban living. With a total area of around 58,000 square metres, the overhaul pairs a dramatic new tower with the surviving post office complex.

The project connects the historic building to Rotterdam’s evolving skyline. The collaboration brings together ODA and Braaksma & Roos Architectenbureau for developer Omnam Group to create a mixed-use destination.

The design asserts a careful balance as the project nears completion. The tower rises from the internal courtyard, elevated on a vaulted plinth, and its façade signals continuity with the original elevations.

It also contrasts with the city’s glass-clad towers. The result is a new structure that honors Rotterdam’s past while embracing contemporary culture and commerce.

Design and Architecture

The four sides of the tower are punctuated by varied arched windows. Each window is set within deep tiled reveals that give the façade texture and rhythm.

Standing at 150 metres tall, the building is conceived as a vertical act of adaptive reuse. The tower is positioned above the historic post office courtyard and anchored by a vaulted plinth that raises it above street level.

This approach preserves the legibility of the historic block. At the same time, it injects a bold, modern identity into Rotterdam’s skyline.

Key design elements include:

• Altitude and scale: a 43-storey form that anchors the corner of Coolsingel
• Window rhythm: arched openings with deep tiled reveals for texture
• Architectural language: a façade that nods to the original elevations, yet intentionally contrasts with contemporary glass towers
• Structural strategy: an elevated tower perched on a vaulted plinth and connected to the courtyard system

Heritage and Restoration

The project foregrounds the historic fabric of the post office, including the 22.5-metre-high vaulted Great Hall. This hall will be restored and reactivated as part of the new mixed-use program.

The original building is one of the few survivors of the 1940 Rotterdam Blitz. It has stood vacant for years and is now being brought back to life through careful conservation and adaptive reuse.

Access at street level is preserved through two existing entrances. The interior Great Hall will become a vibrant public realm lined with shops, galleries, restaurants and cafés.

The transformation envisions the historic hall as a lively anchor for daily city life. It integrates heritage with contemporary commerce.

Adaptive Reuse Strategy

Beneath the historic shell, the project enables a hotel occupying the tower and upper floors. Ground-level retail and cultural use form a continuous pedestrian experience.

ODA frames the intervention as both a memorial and an expression of Rotterdam’s civic vitality. The design invites new audiences to engage with the city’s culture and architecture.

City and Cultural Impact

Post merges preservation with cutting-edge design. The project embodies Rotterdam’s evolving urban identity.

The scheme shows how adaptive reuse can unlock value from heritage buildings. It delivers a modern, mixed-use destination that supports hospitality, commerce, and culture in a compact urban footprint.

Developer and Partners

The initiative brings together ODA and Braaksma & Roos Architectenbureau in collaboration with Omnam Group. The result is a 58,000-square-metre overhaul culminating in a 150-metre tall tower.

The team’s multidisciplinary approach blends architectural invention with historical sensitivity. This honors the post office’s legacy while shaping Rotterdam’s skyline for the future.

Imaging and Timeline

Photographer Andrew Campion has captured the latest imagery of the nearly finished tower. This project first emerged in the public conversation in 2019.

As Rotterdam watches Post approach completion, the building stands as a formal memorial. It is a vivid example of how new architecture can coexist with cherished urban memory.
