Compact precast concrete modular kindergartens tackle urban challenges.
In Lisbon, a public initiative has brought four modular kindergartens to life using precast concrete. This project, developed to meet the growing demand for educational facilities, relied on U-shaped reinforced concrete modules. These prefabricated elements were grouped and overlapped to suit specific programmatic requirements, significantly accelerating construction timelines. Within 13 months, four kindergartens were completed across the city. (Credit all images: Fernando Guerra / FG+SG)
Standardised Design Meets Local Needs
The kindergartens were commissioned through a competition launched by the Municipality of Lisbon, aimed at providing economic, quickly executable, and recognisable structures. The standardised modular design enabled a unified architectural identity across all locations while reducing costs and time. Each building’s visible modular joints reflect the functionality and efficiency inherent in the prefabrication process.
Functional and Durable Structures
The use of reinforced concrete modules ensured structural integrity but also met the project’s requirements for durability and low maintenance. The kindergartens follow a similar layout, featuring two clusters of overlapping U-shaped modules connected by a central corridor. These corridors house vertical and horizontal circulation as well as essential HVAC systems, optimising spatial efficiency and accessibility.
Thoughtful Interior and Exterior Spaces
Designed with both functionality and user experience in mind, the kindergartens feature linear, well-lit corridors that enhance visibility and navigation. Activity rooms, distributed across two floors, have direct access to outdoor spaces. These outdoor areas include non-slip paved surfaces for wheeled toys, garden zones for activities, and carefully selected plant species adapted to the local climate.
Compact Footprint with Sustainability in Mind
Given the urban constraints of the plots, the buildings are compact, with service areas on the ground floor and activity rooms on both levels. Outdoor terraces on the upper floor provide additional recreational spaces. Vegetal covers and permeable surfaces contribute to environmental sustainability, supporting water management and reducing heat island effects.
Prefabrication Reduces Disruption
All structural components were prefabricated in a controlled factory environment and assembled onsite within days. This process minimised waste, noise, and dust during construction, reducing disruption to surrounding neighbourhoods. The efficient approach reflects the broader potential of modular construction for public infrastructure projects, particularly in urban settings.
