Bien GmbH is an architectural office based in Zizers, Switzerland , with a strong focus on multi-family housing and the careful renovation of existing buildings . The firm's work emphasizes the integration of architecture and context, combining functionality, clear design language, and long-lasting, sustainable solutions. Founded by architect Niculin Bisaz , Bien GmbH is deeply rooted in the Grisons region. The firm supports clients from concept development through planning, approval procedures, execution, and handover. Respectful use of materials, historical structures, and surroundings is central to the company’s philosophy. In the field of new construction , Bien GmbH specializes in compact, energy-efficient residential buildings , often enhanced with shared outdoor spaces such as gardens. Especially in village contexts, the office succeeds in creating harmonious ensembles through clarity and precise interventions. Each project meets high standards of comfort, design, and technology. The second pillar of the firm is the renovation of historic buildings . These are not simply restored, but transformed for contemporary use — with respect for materials, structure, and function. The results are spaces with character, depth, and long-term viability. Bien GmbH offers full services according to SIA standards : feasibility studies, preliminary designs, building permit applications, cost planning, tendering, technical planning, site supervision, and quality assurance. All projects are developed in close collaboration with local planners, engineers, and craftsmen. Projects are primarily located in the Grisons region — including Zizers, Chur, Landquart, Arosa, Davos, and the Engadine — but Bien GmbH also undertakes selected projects across German-speaking Switzerland. Clients include private homeowners, public bodies, real estate developers, and housing cooperatives. The promise is simple: to create architecture that is durable, responsible, and rooted in place.

The competences of BRH-Architekten AG lie in the planning and execution of architecturally demanding new buildings and conversions, in the careful handling of existing and historical building fabric and its supplementation with contemporary means. We are interested in aspects of society, economy and the environment and how they affect architecture or can be influenced positively and sustainably by spatial and design means. Our firm handles all service phases according to SIA. The team consists of architects, construction technicians, draughtsmen, construction managers and administration. Thanks to this multidisciplinary composition and our many years of experience in all phases of architectural work, we can guarantee high-quality planning as well as professional and competent construction work. At the centre of the dialogue is the client with his wishes and requirements, whose interests we represent in every situation. We maintain open and direct communication with everyone involved in the project. Only in this way is it possible to combine creative design and construction management and to run a professional project organisation.
