Perili Köşk (Haunted House) is the new headquarters for Borusan Holding. Located within the shell of an early 19th century building, the tower commands a magnificent position on the Bosphorus in Istanbul. Borusan Holding has rented this rooted and historical building for commercial use for the next 30 years.
An office museum concept
The new headquarters serves as a mixed use building, including sports facilities and a restaurant. The 5000m2 nine story building also includes a public art gallery, the “Borusan Contemporary”, an office museum concept that opens its doors on weekends to exhibit varied collections.
The building contains a 22m long light tube installation, of which 6.5m is in outdoors, and is the first of its kind in Türkiye.
We also provided project coordination and contract administration, budgeting and cost control, preparation of tender documents, evaluation of the bids, programming for the design and construction stage, change management, evaluation of claims and site supervision services.
Building retrofit services
As the renovations that were implemented previously included the addition of vertical reinforced concrete structural members (walls and columns), our retrofit helped to resolve the irregularity from the lack of continuity in these members. Furthermore, Arup made a number of adjustments to the existing floors, stairs, elevator, etc. to modify the interior to fit the client’s needs.
