Restoration projects in architecture are undertaken to sustain the heritage value of the structure and to preserve the creative integrity of its creators. The concept of restoration, although intended for minimal intervention from architects, presents the challenge of re-creating and reviving spaces from its time of creation. This would call for a multi-faceted team of structural engineers, craftsmen and architects performing a detailed study of the history and construction principles used then to carefully replicate the physical fabric and essence of the structure such that it simultaneously fits into modern narratives.

Braving the demanding trials of sands of time, the following historic structures make up for some of the best restoration projects taken by renowned architects.

1. Antwerp Port House by Zaha Hadid | Restoration projects

The Antwerp Port House, Europe’s second-largest shipping port, employs over 500 staff members who were working at different sites across the Belgian city. In 2007, the port authorities called out for the relocation of their office to an old fire station in Kattendijk dock. The restoration project aimed to provide unified accommodation for its employees that would align with their interests in future expansion. 

Zaha Hadid Architects had proposed an extension that was to be seated on top of the roof of the existing fire station. The dynamic form possesses a clear cut geometric volume that is accentuated by a triangular glass façade. All in all, the design adds a new dimension to the site, a signature aspect to every Zaha Hadid structure.

The façade of the pre-existing fire station is retained because of its much valued historic importance.

The Kattendijk dock offered many benefits as a site of construction, owing to its waterways that allowed transportation of materials and components required for construction.

2. Philadelphia Museum of Art, Frank Gehry

Built-in 1928, the popular art museum just completed its renovation in 2017 as a part of The Core Project, the first phase of the wider Facilities Master Plan designed by Gehry. The museum authorities aimed for a design that upholds the cultural integrity of the structure and facilitated access to certain spaces that were restricted before.

The first phase marked the addition of new interactive spaces such as, the restoration of the street-level side entrance that remained unused for 40 years, a new espresso bar, bookstore and restored vaulted corridor.

The project retained the use of the New Kasota limestone from Minnesota quarries for walls and floors – the same specific kind used originally in the 1920s.

3. Royal Opera House, Abha Narain Lambah | Restoration projects

The dome draws inspiration from a turtle’s shell and is meant to symbolize the legacy of an indigenous group, namely Lenape. BKSK Architects after holding discussions with the Lenape Centre sought a design that upholds the legacy and culture of the community.
