Project

Marigold House
Care Home

Brief

Central Bedfordshire Council commissioned Concertus to deliver Marigold House, its first new-build care home in 50 years.

The project evolved from initial concepts into a pioneering facility designed to Passivhaus standards, setting a new benchmark for energy efficiency, resident wellbeing, and sustainable care provision.

The clients’ initial concepts for Marigold House required significant refinement, leading to full design development and delivery by Concertus, including a late-stage request during RIBA stages 3–4 to incorporate Passivhaus principles.

Scope

The design for the new Marigold House Care Home provides a three-storey 63-bed care home facility incorporating a day care centre for use by residents and the wider community.

The facility needed to be designed to Passivhaus standards to support the reduction in operational cost of the new care home. To help with planning, stakeholder and end user engagement, Building Information Modelling (BIM) was to be used throughout, to deliver an innovative and accurate design as well as provide the client with comprehensive fly-through visuals.

Every detail was carefully considered to create a truly supportive and inclusive environment for future residents. The design accommodates individuals living with dementia and ensures full wheelchair accessibility throughout the building, internally and externally. Thoughtful touches by our interior architects, such as memory boxes placed outside each room and themed floors, provide gentle cues to help residents navigate their surroundings with confidence and comfort.

Each bedroom has been designed for flexibility and ease of use, featuring spacious accessible bathrooms and specialist profiling care beds. All rooms are design to be easily adapted to existing or developing dementia requirements as residents needs changed over time. Additional amenities, including a health and beauty salon and a bookable guest room, further enhance the quality of life for residents and their families.

External areas associated with the build included an extensive landscaped area which wraps around the building to encourage residents to utilise these spaces and have access to private and secure outside areas, which will support their health and wellbeing needs. There was a real drive and focus on opportunities to develop an ‘Outside/Inside’ strategy. This is where external spaces become an extension of the internal spaces, alongside bringing external features inside, through elements such as planting and materials. Included in the design are terraces and balconies on the upper two levels to allow residents throughout the building to have access to outside spaces. The design looks to create a feeling of home while balancing the needs of the residents.

Passivhaus principles are at the heart of the design, ensuring exceptional energy efficiency and resident comfort. The airtight building envelope, combined with advanced techniques, dramatically reduces heat demand. A combination of air source heat pumps and solar thermal systems meets all heating and hot water requirements, substantially improving the facility’s overall efficiency.

Beyond energy performance, Passivhaus design enhances health and wellbeing. Consistent indoor air quality and advanced ventilation systems help minimise the spread of airborne germs and contaminants, reducing the risk of illness outbreaks among residents and staff. This controlled environment supports infection control while maintaining sustainability.

Residents also benefit from improved air quality and superior thermal comfort, creating a safe, healthy, and welcoming space that prioritises both care and environmental responsibilities.

Result

Marigold House is set to achieve Passivhaus certification, one of the only few care homes in the UK to be certified, and the first for Central Bedfordshire.

Once certified, it will also become the largest Passivhaus standard care home facility in the country. Open to residents from February 2025 with the official opening taking place in September 2025, the client is exceptionally pleased with our quality of work and service delivered. This landmark project has established a new benchmark within the health sector, combining cutting-edge sustainable design with exceptional resident wellbeing.

Operated by leading care provider Care is Central, Marigold House now provides much-needed care facilities for Leighton Buzzard and sets a precedent for future government-commissioned projects.
