The Eichhof West site forms the northern gateway to the Lucerne South development area, which is currently undergoing significant transformation. In addition to the Eichhof brewery, a residential and commercial development will be completed by 2026, based on a development plan comprising four building plots.

Building Plot B is prominently located in the southern part of the site and defines its appearance towards the street. The three-storey base accommodates commercial spaces as well as public-oriented uses. Above this, the building is divided into two parts: a longitudinal volume with four residential floors and a high-rise building with 14 residential floors. From the more than one hundred apartments, most tenants enjoy views of Pilatus, Rigi or Lake Lucerne. Bronze-coloured metal frames sharply define the edges of the building and, together with the dark photovoltaic elements, form a precisely composed façade envelope.

We are delighted to have welcomed so many interested visitors who joined our tours as part of Open House Zürich 2026.

This year, we had the opportunity to present two projects. One of them was the office building Utoquai 55, a commercial building featuring one of the most beautiful terraces on Lake Zurich – a unique setting with impressive views across the lake and the city. The seven-storey building was designed by architect Armin Meili and constructed between 1961 and 1965. As part of the comprehensive renovation by Stücheli Architekten, the distinctive character of this listed building was preserved while carefully adapting it to today’s requirements.

We also presented the B2Binz building, home to the House of Interiors and numerous companies working in the fields of design, interior architecture and production. Together with the Iria Degen Interiors office, we guided visitors through the building, offering insights into its architecture and the diverse interplay between its different uses and companies.

Once the capital of the Kingdom of Italy, Turin is closely connected to the history of the House of Savoy. Its magnificent palaces and spacious squares are a reminder of the time when the Savoys made the city their residence. From 1861 to 1865, Turin was also the first capital of a united Italy.

Turin also has plenty to offer in terms of architecture. Highlights include the Teatro Regio, designed by Carlo Mollino, as well as the former Fiat factory Lingotto, with its distinctive rooftop test track. Around 1989, the former factory complex was transformed by Renzo Piano into a multifunctional urban center. Another architectural highlight is the Palazzo del Lavoro by Luigi Nervi, whose striking concrete and steel ribbed structure remains an impressive example of modern architecture.

We celebrated and enjoyed delicious meals in traditional osterias, where we experienced the rich, home-style cuisine of Piedmont. Good food, great company and relaxed evenings made the perfect end to our days in Turin.

Although the project did not achieve first place, we are pleased to have been awarded 3rd place in the competition for the new parish centre in Baar. With the project «Alabaster», we explored the historic centre and its surroundings.

The Catholic Church of St. Martin and St. Anna Chapel have formed the spiritual and spatial centre of Baar for centuries. The «Alabaster» project builds on this historic structure and strengthens it with three building volumes. They complement the existing buildings, define the surrounding open spaces and create new connections between the Church Square, Asyl Square and St. Martin’s Park.

Open House Zürich invites visitors to discover selected buildings and architectural projects across the city. This year, two of our projects are part of the programme: B2Binz and Utoquai 55. We will be on site during the visits, offering insights into the architectural concepts behind the projects, as well as their development and realization.

B2Binz / HOUSE OF INTERIORS / URBAN PRODUCTION
During the guided tour, Eva Schaub and Iria Degen will engage in a dialogue about the concept of the open-plan space and its spatial organisation, floor plan design, functionality and usability. HOI is a place for design, craftsmanship and interior architecture. The first two floors of the new B2Binz building bring together around 3,400 m² of studios, workshops and design offices under one roof, creating a shared centre for creative production.

Office building Utoquai 55
The office building at Utoquai 55 occupies a prominent urban location on the shores of Lake Zurich. Designed by Armin Meili between 1961 and 1965, the building has been under heritage protection since 2013 and was comprehensively renovated by Stücheli Architekten. The renovation focused on preserving the primary structure and the two-storey entrance hall, as well as the heritage-sensitive reconstruction of the building envelope. The guided tour with Henri Rochat provides insights into the architectural aspects of the renovation.

The new edition of our project poster tells the story of the residential and commercial building at Rennweg 53 in Zurich, offering insights into the comprehensive renovation — from its architecture and heritage conservation to the careful preservation of its historic fabric.

We are happy that our Hegianwandweg, Zurich renovation and refurbishment project has been featured as Project of the Month on the Aufbruch statt Abbruch knowledge platform.

Originally built between 1950 and 1952 for the Familienheim-Genossenschaft Zürich (FGZ), the housing estate has been carefully refurbished through targeted, minimal interventions. The project focused on preserving affordable housing, implementing a tailored insulation strategy, and retaining the building's defining architectural features—demonstrating how sustainable transformation of existing buildings can be achieved.

Building Plot C is located in the north-eastern part of the site, where the terrain rises significantly. Perpendicular to the slope, an elongated building volume emerges, merging with the terrain in the lower levels before rising out of the landscape and reaching a height of 35 metres. The building accommodates sixty rental apartments as well as commercial spaces in the plinth level.

A particular quality of the building is the continuous balcony layer that wraps around the structure, providing access from all rooms and significantly shaping its architectural expression. Precisely assembled, prefabricated concrete elements form a three-dimensional building envelope that makes the internal structure of the building volume legible on the exterior.

The buildings at “Eichhof West” are constructed according to the Gold Label of the Swiss Sustainable Building Standard (SNBS) and are characterised by carefully selected, durable and sustainable materials.

We are delighted to look back on our 80 Years Stücheli anniversary celebration. Together with familiar faces, friends, and valued guests, we enjoyed a wonderful evening filled with great conversations, memorable encounters, excellent food, and our anniversary beer, “Stü80.” The warm atmosphere made the celebration truly special.

A heartfelt thank you to all our guests, employees, partners, and everyone behind the scenes who helped make this anniversary celebration such a memorable occasion.

Thank you for celebrating with us.

The historic residential and commercial building at Rennweg 53 in Zurich is entering a new chapter. At around 25 meters in height and with seven floors, it is one of the defining buildings along Rennweg.

Its central location in a densely built urban area presents challenges: limited space requires carefully planned construction logistics. A crane portal makes it possible to efficiently integrate the construction process into the constrained urban environment – a key prerequisite for carrying out this complex refurbishment project.

The transformation balances the preservation of the historic structure with targeted structural interventions. These include a new base slab, ground floor adjustments to create step-free access, a new elevator shaft, and measures to improve earthquake resistance.

All work is carried out in close coordination with heritage conservation authorities. Accompanying building archaeology investigations provide fascinating insights: dendrochronological analyses reveal those parts of the load-bearing structure date back to the early 17th century.

A project that preserves the past while making room for the future.

The former commercial area of Leutschenbach, located on Zurich’s northern edge, is currently undergoing a transformation into a mixed-use neighborhood with a strong residential component. Along Hagenholzstrasse, the nearly 80-metre-high tower stands as a solitary landmark, with a generous park space opening up on its street-facing northern side. This open space links the new development to the green corridors, pathways and planted areas that will in future run through the district.

The publicly accessible ground floor accommodates a café, retail units and other service-oriented uses. The 26 upper floors comprise 224 rental apartments, predominantly 2.5- and 3.5-room units, primarily aimed at a younger demographic. Residents enter the building via a double-height entrance hall. With a roof terrace and shared facilities, the sixth-floor functions as a communal meeting space. The top four floors house maisonette apartments, lending an exclusive character to living at elevated heights.
