Sponda celebrates topping out milestone at its Signe development in Helsinki city centre

Professional design, well-managed site operations, and the skill of the builders have kept the project steadily on track. In October, the site - led by main contractor Jatke Toimitilat - was awarded Construction Site of the Year 2025 in Finland by Rakennuslehti. The recognition highlighted excellent collaboration between the parties, clarity of the site operations, and sustainable practices among all teams involved.

Investments in wellbeing drives demand

Designed to meet the highest environmental standards, Signe is one of the most prominent property development projects in central Helsinki and, once completed, will bring new vibrancy to central Helsinki. The attractive business premises will draw new businesses and footfall to the area and strengthen the vitality of the city centre. Interest in the property has remained strong during construction, and the office spaces are now almost fully leased.

“Companies are increasingly investing in work environments that support employee wellbeing, learning, and frictionless daily work, and modern, sustainably designed premises are therefore a key part of this development. Sponda responds to companies’ changing needs by actively investing in the development of its properties. The Signe project is an excellent example of this – it brings high-quality office space to the heart of Helsinki, meeting the demands of modern working life while enhancing the vibrancy of the cityscape,” says Sponda’s CEO Christian Hohenthal.

Signe is being built in accordance with the highest environmental standards and aims to achieve LEED Platinum environmental certification, an A-level EPC rating, WELL Gold level certification, and EU Taxonomy alignment. The project strongly focuses on reducing carbon emissions – material-related emissions are more than 30 percent lower compared to conventional construction methods.

In addition to office space, Signe’s open and high ground floor will include impressive retail and restaurant premises in a lively pedestrian area. Leasing of these spaces is currently underway.

Signe in brief:
• Floors: 8
• Total leasable area: 16,980 m²
• Office space: 12,614 m²
• Retail space: 4,366 m²
