Dark Hill Hotel Restaurant│Transformed with Panorama

Challenge: Unleashing the Bosphorus Panorama From the Rooftop

Restaurants with high comfortability are chosen by visitors or tourists. The Dark Hill Hotel Restaurant serves its top floor as a high‑notch restaurant with the belief that the view of Istanbul is the attraction of this venue. They are right: guests enjoy a bird’s‑eye perspective of the city while dining and drinking. The experience is already wonderful. But management wanted to elevate comfortability to the next level—and did so by installing a Lean‑to Retractable system from Libart. The retractable glass roof system changed the game.

Libart’s concept of motion in architecture is influencing cafés and hotels globally. Dark Hill took notice of similar rooftop transformations documented on Libart’s site, especially installations in Chicago, and recognized how such systems could redefine their own rooftop bar.

Research confirms that diners often choose restaurants for the view, then food, then ambiance. At a prime hilltop location, rent is high—reflecting the visual value. But views must be delivered flawlessly. Owners needed enormous glazing without visual interruptions: windows large enough, unobstructed, giving panoramic vistas of the Bosphorus.

Thus the challenge: create an expansive, elegant rooftop experience with visual clarity, weather resistance, all‑season operability, and architectural flair worthy of Istanbul’s skyline—and deliver it without compromising structural performance or guest safety.

Solution: Libart Lean‑To Roof & Panora Vertical Retracting Windows

At Dark Hill Hotel, Libart installed a 6.2 m × 22 m Lean‑To Retractable Roof system using triple‑layer insulated glass (6 mm tempered Sunenergy + 12 mm air gap + 4+4 mm laminated units), powered via motorized controls. The roof opens and closes smoothly for seamless transition between enclosed and open-air modes, Libart.

Additionally, guests face seven units of Panora – View Vertical Retracting Windows (W3 system, roughly 4 m wide × 3.6 m high), installed along facade sides, giving unobstructed scenes of the Bosphorus. These retract downward to become glass balustrades, offering fresh air without safety trade-offs.

The combination—the roof and windows—creates a stunning multi-tiered operation where ceiling and walls respond to weather, occupancy, and time of day. Motions are silent, smooth, and button activated—transforming the space in seconds.

Benefits: Majestic Views, Unparalleled Flexibility, Elevated ROI

✔️ Panoramic Freedom with Safety

Guests now enjoy frame‑free, vertical vistas of Istanbul—including Bosphorus’s glimmering water and city panorama. When windows retract, they merge interior with rooftop terrace; when closed, they revert to safe, insulated glass balustrades, Stoett Industries.

✔️ All‑Season Operation

Previously weather-sensitive, the rooftop is now usable year-round. The roof and windows close during winds or rain, maintaining warmth and clarity; when weather permits, they open for full exposure to fresh air and daylight. ROI significance skyrockets, as the venue operates daily throughout seasons.

✔️ Aesthetic Impact Meets Structural Integrity

The retractable system seamlessly integrates into the existing architecture. Unlike bulky garage doors or folding panels, the lean-to roof and Panora glazing are clean, sophisticated, and engineered to withstand wind loads—even at elevated heights.

✔️ Emotional Architecture and Guest Engagement

With each retraction sequence—roof rising, windows lowering—the space becomes alive. Guests feel part of the unveiling. It reinforces the impression of exclusive, majestic hospitality—from first sunset to late-night skyline glow.

✔️ Strategic Differentiation

Dark Hill Hotel Restaurant has become known not just for views, but for its responsive architecture. A marketing edge, yes—but also an emotional one. Presence becomes performance: rooftop ceilings and walls in motion elevate dining to a memorable event.

✔️ Operational Ease for Staff

Motorized operation removes physical labor, risk, or disruption. The system responds to staff or environmental triggers—opening for events or closing for safety without delay or complexity.
