Swiss Re Group Opens 50,000-Square-Meter LAKE Office Building at Zurich's Campus Mythenquai

ZURICH, Oct. 26, 2026 — Swiss Re Group inaugurated the new LAKE building at Campus Mythenquai in Zurich on Monday, completing the campus on the shores of Lake Zurich with around 50,000 square meters of office space, the company announced. The opening was held together with representatives from the City of Zurich, politics and business.

The building, equivalent to roughly 538,000 square feet, is located at Mythenquai 50/60 in Zurich's 8022 postal district. Swiss Re said LAKE is the final addition to the Mythenquai ensemble for the foreseeable future.

LAKE Building Design and Sustainability Features

LAKE was designed by Meili & Peter and GFA Gruppe für Architektur. Swiss Re said the building combines architecture with resource-efficient building technology.

As with the neighboring Swiss Re Next office building, water from Lake Zurich helps cool LAKE, while the concrete structure acts as thermal storage. Demand-controlled ventilation and photovoltaic panels on the roof complement the energy concept. According to Swiss Re, the building meets the Minergie-P ECO and LEED Platinum sustainability standards.

Technology Tenant Broadens Mythenquai's Business Mix

An international technology company will become the building's main tenant, broadening the mix of international businesses at Mythenquai, an area traditionally home to several large insurance companies, Swiss Re said. Following completion, the office spaces will be handed over to tenants for their individual fit-outs and subsequently occupied in stages.

A technology company has secured 10,000 square meters in the planned Lake Campus on Mythenquai. Occupiers in the Lake Zurich office cluster also include Swiss Re, Zurich Insurance, Google and Amazon Web Services.

Gianfranco Lot, Country President Switzerland at Swiss Re, said: "Around 100 companies were involved in the construction of LAKE, including numerous Swiss SMEs. At the same time, new publicly accessible amenities will open up the site further to the surrounding neighbourhood. LAKE therefore represents not only modern architecture, but also local economic value creation and benefits for Zurich as a business location."

Public Amenities and Site History

New amenities for the neighborhood include publicly accessible dining facilities and a landscaped lakeside terrace. The new public Hafen Enge car park, offering around 140 parking spaces, is expected to open in November 2026.

The Mythenquai site has a history spanning more than a century. Its foundations were laid in 1913 by architects Emil Faesch and Alexander von Senger with the building now known as Swiss Re Altbau. In 2017, Swiss Re moved into the Swiss Re Next building, designed by Diener & Diener Architekten.

Zurich Office Market Context

The opening comes as Zurich's office market shows a split between overall availability and demand for premium central space. The Zurich region's office availability rate stands at 5.3%, unchanged year over year, while available space declined by 4,900 square meters. In the second quarter of 2026, the regional availability rate fell to 5.1%.

Demand remains consistently high for offices in central locations, while the supply of high-quality workplaces there is limited, pushing prime rents higher. Across Switzerland's five largest office markets, available space totaled 1.03 million square meters at the end of 2025, up 37,100 square meters, or 4%, from a year earlier. The average availability rate rose to 5.2%, from 4.1% at the end of 2019.

Swiss Re Group Background
