The practice is known for its pioneering work in low-energy design and creating buildings that foster community and well-being.

Where is Cullinan Studio's Headquarters?

HQ Function

The London headquarters serves as the primary design studio, administrative center, and collaborative hub for Cullinan Studio's architectural and masterplanning projects. It's where creative concepts are developed, projects are managed, and the cooperative ethos of the practice is nurtured.

Notable Features:

The Foundry, designed in-house by Cullinan Studio, is an exemplar of sustainable architecture. It features a distinctive timber frame, passive ventilation, excellent natural light, rainwater harvesting, and was one of the UK's first BREEAM 'Excellent' rated buildings. It also provides space for other like-minded organizations.

Work Culture:

The work culture at Cullinan Studio is deeply rooted in its cooperative structure (Employee Benefit Trust). It fosters a democratic, collaborative, and supportive environment where all employees have a voice. There's a strong emphasis on shared learning, ethical practice, and a commitment to designing buildings that positively impact people and the planet.

HQ Significance:

The Foundry is highly significant as it embodies Cullinan Studio's core values of sustainability, collaboration, and innovative design. It serves not only as their operational base but also as a tangible demonstration of their architectural principles and a welcoming space for partners and the community.

Values Reflected in HQ: The headquarters distinctly reflects Cullinan Studio's values: sustainability (eco-friendly materials, energy efficiency), collaboration (open-plan spaces, shared facilities), innovation (pioneering green building techniques), and community (housing multiple organizations).

Location:

While Cullinan Studio is headquartered in London, their architectural influence and projects extend internationally. They have experience working in various global contexts, adapting their sustainable and collaborative design approach to different climates, cultures, and regulatory environments. Global project support typically involves their London-based team collaborating with local expertise and undertaking site visits as required.
