Marthagården
Rebuilding Childhood with Nature and Purpose
The rehabilitation and extension to the children’s institution Marthagården integrates sustainability into children’s daily lives. Here, children actively learn about food production, organic farming, preparation, and composting.
The institution, which has operated for over 125 years, was previously divided into two separate sections, limiting interaction between staff, parents, and children. The renovation and extension have unified the institution, creating a shared entrance.

The rehabilitation is rooted in preserving and repurposing existing structures. Reclaimed materials from the modernization of the original buildings were incorporated into the new extension. Additionally, six tons of wooden furniture were refurbished and reused instead of being discarded.
The energy-efficient design incorporates natural ventilation, passive solar heating, and rooftop solar panels, meeting the 2015 low-energy building standards. These initiatives result in minimized heating and cooling costs while maintaining a comfortable indoor climate.




Upon arrival, families can engage with staff, observe daily activities, and participate in sustainable initiatives such as waste sorting, organic gardening, and food preparation. A green parent’s corner serves as a community hub where used clothes, books, and toys are exchanged, reinforcing a culture of reuse.
