Located in Sofia, Bulgaria, RUHouse II is a contemporary residential complex designed to combine urban comfort, premium materials, and panoramic views of Vitosha Mountain. The project creates a direct connection between city living and nature through its glass-dominated façade design, expansive glazing areas, and carefully planned residential spaces.

Designed by City Control Ltd. and developed by RUHouse 2 Ltd., the building focuses on functional layouts, flexible interiors, and high-quality architectural solutions. The minimalist façade concept uses transparency and clean lines to create a modern expression, while the large glazed surfaces allow natural daylight to penetrate deep into the interiors, changing the atmosphere of the apartments throughout the day.

The building envelope was completed with Schüco aluminium systems from the ALUKÖNIGSTAHL portfolio, selected for their combination of thermal performance, durability, aesthetics, and advanced engineering.

The main façade solution is the Schüco FWS 50 façade system, which enables slim-profile curtain wall construction and large glass surfaces while providing excellent weather resistance and thermal insulation. The system supports the building’s lightweight visual appearance while meeting the demands of modern residential architecture.

The project’s windows and doors use the Schüco AWS/ADS 70.HI series, offering high thermal and acoustic insulation, concealed hardware, smooth operation, and refined minimalist detailing. These aluminium systems contribute to both the building’s energy performance and its premium architectural character.

For seamless indoor-outdoor connections, RUHouse II incorporates the Schüco ASE 80.HI sliding system, featuring large transparent panels, narrow profiles, panoramic views, and improved energy efficiency. The system transforms balconies and living areas into open, light-filled spaces while maintaining year-round comfort.

Key advantages of Schüco systems at RUHouse II include:

• Energy efficiency: Advanced aluminium solutions help reduce energy consumption and maintain a stable indoor climate.
• Security: The systems provide high resistance against burglary and extreme weather conditions.
• Durability: Aluminium profiles and treated glazing deliver long-term resistance to corrosion, mechanical stress, and environmental exposure.
• Aesthetics: Minimalist profiles, precise detailing, and large glass areas create a timeless contemporary architectural appearance.

RUHouse II is more than a residential development, it is an example of how advanced façade engineering, sustainable performance, and modern architectural vision can work together. Through the integration of Schüco FWS 50, AWS/ADS 70.HI, and ASE 80.HI systems, the project establishes a new benchmark for premium urban living in Sofia.
