The project comprises the construction of a new care home planned to include approximately 100 beds, with a lettable area of 6,568 square metres. The project is intended to be certified in accordance with Miljöbyggnad Silver.

-We are very pleased to now take the next step and formalise our collaboration with both Vardaga and RO-Gruppen. Together, we look forward to delivering a project with high climate ambitions that contributes to attractive and functional living environments for the elderly. The project marks our first return to new construction and represents an important part of our strategy to grow within community properties with stable and long-term cash flows," says Per Nilsson, CEO of John Mattson.

John Mattson will own and manage the property on a long-term basis, while Vardaga will be responsible for the operational activities and will contribute extensive experience in the development and operation of care homes.

-We look forward to the collaboration with John Mattson and to jointly developing additional care home capacity in an area where demand is high. For us, this is about creating more than a care home - we want to create a home, with a focus on personal care and a meaningful everyday life," says Jon van Geffen, Head of Growth & Property at Ambea.

The construction contract with RO-Gruppen comprises a design-and-build contract, under which RO-Gruppen will be responsible for both the design and construction of the care home.

-We are proud of the continued confidence and to now take the project into the implementation phase. Together, we are creating a modern and sustainable environment with high standards for quality and climate performance," says Annika Grönberg, Deputy Business Area Manager at RO-Gruppen.

Both agreements are conditional upon the granting of a building permit. Construction is planned to commence in the second quarter of 2026, with completion scheduled for the fourth quarter of 2028.
