The Sequoia Office Building in Nové Roztyly Enters the Next Phase of Construction

“The completion of the foundation slab represents one of the most important milestones of the entire construction process. It is during this phase that the building takes on its definitive footprint, allowing us to begin the realization of individual floors. Sequoia is being built under challenging geological and terrain conditions, which is why we have emphasized a high-quality technical solution for the foundations and its long-term durability from the very beginning. We are pleased that all work is progressing according to schedule and the project is moving into the next stage,” said Martin Unger, Technical & ESG Director at Passerinvest Group.

Sequoia as Part of the Transformation of Nové Roztyly

Sequoia is the next step and a prerequisite for the transformation of the Nové Roztyly area, where Passerinvest Group is gradually creating a modern urban district that combines office buildings, public spaces, services, greenery, and future residential development, which will receive the greatest emphasis. The project follows the already completed Roztyly Plaza building and further develops the locality near the Roztyly metro station and Krčský les (Krč Forest).

Upon completion, the Sequoia building will offer more than 33,000 m² of state-of-the-art office space, a canteen with a café, shared meeting spaces for up to 200 people, a rooftop terrace with greenery, private loggias, and facilities for cyclists. In the underground floors, 488 parking spaces will be available to tenants, including electric charging stations at designated spots.

Sustainability is addressed comprehensively in the Sequoia project. The building will utilize heat pumps, photovoltaic panels, and energy-efficient heating and cooling systems. Great emphasis is also placed on indoor environmental quality, an ample supply of fresh air, water management—including the implementation of blue-green infrastructure measures—and supporting biodiversity in the surrounding area. The project aims to achieve the highest level of environmental certification, BREEAM Outstanding.

What Sequoia Will Offer:

• 33,000 m² of offices and 375 m² of retail space
• Up to 3,500 m² of office space on a single floor
• 755 m² of rooftop gardens and private loggias
• 488 parking spaces in underground garages (some with electric charging stations)
• 11 office floors
• High visibility from Prague’s busiest transport arteries – the Magistrála (5. května street) and the Jižní spojka (City Ring Road)
• Low operating costs
• A new direct exit to the building from the Jižní spojka
• A canteen with a café, a rooftop lounge terrace with greenery, and private loggias overlooking Krčský les
• Shared meeting spaces for up to 200 people
• BREEAM Outstanding certification
• Project completion in the first half of 2028

Challenging Foundation Work Below Groundwater Level

Earthworks on the excavation pit took place from September 2025 to April 2026, during which more than 66,000 m³ of soil was excavated from the site over eight months. The excavation and shoring work was followed by the construction of the foundation slab, which took approximately two and a half months. The foundation slab itself covers an area of nearly 5,800 m² and has a thickness of 750 mm. Its construction required approximately 4,500 m³ of concrete and 720 tonnes of steel reinforcement.

The building is founded on 219 piles with diameters ranging from 900 to 1,500 mm, with a total length reaching almost 1.6 kilometers. The substructure design focuses on long-term resistance to groundwater and other environmental factors. Protection against water ingress is ensured by a “white box” (bílá vana) system using waterproof concrete and special sealing elements. The technical solution also includes protection against stray currents, which contributes to the long-term durability of the reinforced concrete structures.
