Hosannahs was founded in Caerphilly, Wales, in 2019, where early projects established the practice within the residential and regeneration sector. The company received three consecutive industry awards recognising its work and development during its initial growth period.

​

As our client base expanded across Wales, England, and Scotland, we opened an Edinburgh branch in 2022 to support projects in the region. Today, Hosannahs operates across the UK, providing coordinated interior and architectural technology services for residential and commercial clients.

Regulatory & Professional Framework

​

Hosannahs is registered with Local Authority Building Control (LABC) and coordinates with building control processes to support regulatory compliance and technical development throughout projects. Early engagement with building control informs design decisions and helps address compliance considerations at appropriate stages.

Registration with Local Authority Building Control supports our approach to regulatory coordination. Early engagement with building control helps identify compliance considerations during design development, allowing technical issues to be addressed at an appropriate stage of the project.

​

All services are delivered under formal written terms of engagement consistent with recognised professional standards.

Leading the Way as Ambassadors for Sustainability in Design

As proud ambassadors for sustainability in design, we actively champion environmentally responsible practices across all our projects. This role is not simply a title but a commitment to creating spaces that harmonize with the environment while setting new standards of excellence. A key aspect of our ambassadorial efforts is our active involvement with the prestigious London Build Expo.

Colleagues Working Together

​

​

  • Expert Knowledge: We gain cutting-edge insights from top industry professionals, ensuring our designs stay ahead of the curve.

  • Strong Partnerships: We collaborate with leading architects, suppliers, and engineers who share our sustainable vision.

  • Access to Innovations: We bring the latest eco-friendly materials and energy-efficient solutions to your projects.

  • Local and National Impact: We connect global innovations with our work in Edinburgh, Caerphilly, and beyond, enriching communities.

  • Sustainability Advocacy: We actively promote and implement green practices, influencing the future of design.

The London Build Expo, a cornerstone event in the UK construction and design industry, provides an invaluable platform for fostering innovation and collaboration. As part of our ambassadorial role, we leverage this connection to stay at the forefront of sustainable design trends and emerging technologies. Our participation at the Expo allows us to engage with industry leaders, access cutting-edge materials and techniques, and contribute to meaningful dialogues about the future of design.
