Keilaniemen Portti demonstrates how strategic partnerships and innovative project management create exceptional value in sustainable construction.
Rising on Espoo's skyline in Finland, Keilaniemen Portti is not just any office building. It is an architecturally unique project set to become one of Europe's tallest wooden office buildings upon completion. The 15-story building covers a gross area of 29,629 sq m and will feature office spaces, a conference center and auditorium, a restaurant, a sauna, a rooftop terrace, and underground parking.
The project brings together Varma Mutual Pension Insurance Company as commissioner, Jatke Toimitilat Oy as project management contractor, and Ramboll for comprehensive design and BREEAM certification. Peikko Finland supplied steel structures for the project.
"Collaboration began well ahead of the first deliveries. Together with structural designers, we discussed connection solutions and improved our products. Good preliminary planning and excellent project management also streamlined the execution and deliveries," Peikko’s Project Manager Elina Hietanen explains.
Project management model drives success
Jatke Toimitilat Oy's project management contracting approach delivered additional value for the project. This model enabled agile decision-making, aligned all stakeholders around common objectives, and supported sustainable development through comprehensive early-stage planning.
Mikael Lähteenmäki, Work Manager at Jatke Toimitilat Oy, guided the project from development through completion: "The project management model used demands expertise and understanding from the entire supply chain, but when functioning well, it provides enormous benefits. Throughout the project, there has been excellent team spirit and common objectives, which have been the project's greatest asset."
Technical innovation meets sustainability
The building's hybrid structure seamlessly integrates CLT wood and steel through expertly designed connections. Antti Pekkala, Ramboll's structural design Project Manager, highlights the innovation value: "This has been a technically special project in many respects, providing opportunities to innovate. Such projects create solutions that undoubtedly support future timber construction projects."
Tekla-based 3D modeling enabled precise coordination between designers and contractors, while sustainability considerations shaped every decision from material selection to lifecycle management.
"Precise timing in such a hybrid project requires model-based planning. When collaboration is effective, ambitious projects like this become achievable," Pekkala adds.
Engineered solutions, precise delivery
Peikko's involvement from the early development phase through final delivery exemplifies a solution-focused partnership. The company delivered approximately 600 DELTABEAM® Green beams (totaling 3.7 km (2.3 mi)), beam-column connections, and complementary steel structures. These beams enable the load-bearing structure to achieve fire class R120 without additional fire protection. Distributed deliveries required precise coordination.
"Anchor rails for facade support were integrated into beams at the factory, facilitating installation. We always aim to flexibly meet customer needs and solve challenges," emphasizes Hietanen.
Smooth execution under challenging conditions
Area Manager Jaakko Kinossalo from Jatke oversaw the structural and facade phases, completing frame construction precisely on schedule in March 2025 without weather protection. The project's scale, height, proximity to a busy ring road and the sea, seasonal variations, and hybrid technology demanded exceptional preparation.
"Collaboration among project parties was exceptional during both design and implementation. Challenges were quickly and positively resolved together," says Kinossalo.
Comprehensive planning and joint preparation proved essential for managing complex logistics and technical requirements.
"Nothing came as a surprise since everything was anticipated. When everyone pulls together, there's no internal competition. Such collaboration achieves excellent results," praises Kinossalo.
Results that matter
With the structural phase complete, Keilaniemen Portti transitions to interior works with a solid foundation—both structurally and collaboratively. The project demonstrates measurable value: on-time delivery, innovative hybrid construction, sustainable design, and seamless stakeholder coordination.
Beyond technical achievement, Keilaniemen Portti proves that when all parties commit to shared goals and transparent collaboration, exceptional results follow. The project sets new standards for sustainable construction and partnership-driven project management, delivering value that extends far beyond the building itself.
