The shift of office demand toward the emerging Levent–Maslak axis, now established as the new CBD, significantly affected office buildings in this area, leaving many of them vacant. Despite this downturn, the investors adopted a strategic approach, choosing to invest in the renovation of both the building’s façade and interior spaces.

​

Located adjacent to one of the city’s busiest traffic arteries, noise was a primary concern for existing office users. To address this, all windows were replaced with double-glazed systems. Additionally, the introduction of rock wool insulation behind the new ceramic façade improved energy performance while also contributing to acoustic comfort.

​

Due to the existing uninterrupted linear window configuration, the south façade was exposed to excessive direct sunlight. This resulted in glare, high contrast within office spaces, and increased cooling costs during the summer. The addition of smart sun-shading systems allows for effective solar control during summer, while still permitting daylight penetration during the winter months.

​

The “fifth façade,” the roof, was also fully reconfigured. A new steel structure replaced the existing roof, which was no longer performing adequately.

​

The renovation of the façade and common areas significantly improved the building’s image, reduced operational costs, and attracted new tenants in a short period of time—resulting in a rapid return on investment.
