Ramseier + Stucki Architects

What Ramseier + Stucki Architects does

Ramseier + Stucki Architekten AG is a Swiss architecture and real estate development firm headquartered in Muri b. Bern, operating since 1963. The firm pursues a vertically integrated residential development model: it acquires land in the Canton of Bern region, designs and builds ownership apartments (Stockwerkeigentum), and disposes of them as developer — exemplified by an active pipeline including Hofgarten Laupen (22 apartments), Bächi Hünibach, Hunzigerüti Rubigen, Verve Seedorf, and Panoramapark Grenchen. In parallel, it offers interior architecture for residential, commercial, and hospitality clients, and runs property sales and valuation services through the ac-i subsidiary and smba. The firm is privately held by the Zaugg family, with Beat Zaugg as sole owner since 2012 and Deborah Zaugg joining the board in 2021.

Its core products are architect-designed residential developments and the QUBE modular living system, an SNBS-certified proprietary housing concept that standardizes aspects of the design-to-delivery process. The business monetizes through a mix of development gross profit on apartment sales, architecture and interior design fees, and brokerage/valuation fees via ac-i. Customer mix is overwhelmingly B2C (individual apartment buyers) supplemented by a smaller B2B interior architecture book (including DC Bank Bern and hospitality projects). With ~40–45 employees, multi-project development exposure, and 60+ years of regional brand heritage (including a Prix SVC 2019 recognition), the firm operates as a mid-sized, family-controlled Bern real estate developer rather than a scalable platform.

Product overview

A complementary brand, aci – atelier für concept & immobilien ag, handles property sales, valuation, and financing services.

Direct peers

• Anliker AG: Swiss construction and real estate group combining general contracting, architecture, and project development. Most directly comparable to r+st as an integrated architecture-and-developer firm serving the Swiss residential market with a similar vertical business model.
• Burckhardt+Partner AG: Swiss architecture firm with deep practice across residential, commercial, and healthcare buildings. Closely comparable to r+st's architecture-led service model and project profile, though operating across multiple Swiss cities rather than concentrating in Bern.
• Itten+Brechbühl AG: Swiss architecture and general planning firm delivering design-led residential, commercial, and infrastructure projects nationwide. Comparable to r+st as an architecture practice that also engages in development and large-scale residential design commissions.
• Suter Architekten AG: Swiss architecture and urban design practice with significant residential and masterplanning work. Comparable to r+st as a design-quality architecture firm involved in residential new-build and mixed-use projects across Switzerland.

Broad incumbents

• Losinger Marazzi AG: Bouygues Construction subsidiary operating as a Swiss developer and general contractor with integrated real estate development. Comparable to r+st on residential new-build construction and development, with a similar design-quality orientation but at much larger scale.
• HRS Real Estate AG: Swiss real estate developer focused on complex residential, commercial, and infrastructure-related projects. Comparable to r+st in delivering design-led residential developments, but operating at substantially larger project scale and canton breadth.
• Halter AG: Swiss-wide construction and real estate developer with integrated general contracting and project development. Operates at materially larger scale than r+st across multiple Swiss cantons, making it the most relevant national peer for r+st's architecture-led development model.
• Allreal Holding AG: Swiss-listed real estate company combining development, general contractor services, and investment portfolio. Overlaps with r+st's residential development and investment positioning in the greater Zurich/Bern Swiss-German corridor, but with broader national reach.
• Steiner AG: One of Switzerland's leading general contractors and real estate developers, active in residential, commercial, and mixed-use. Competes with r+st on residential new-build projects and offers a broader national footprint with deeper capital resources.

Regional players

• Eberhard Sutter Architekten: Swiss architecture firm focused on residential and commercial projects with similar design-quality orientation to r+st. Placed as a regional peer because, like r+st, it concentrates on quality residential commissions in German-speaking Switzerland, though in a different canton footprint.
