Sustainable Design Experts I Norfolk Architects

We deliver beautiful low-energy buildings with a strong sense of place.

Hudson Architects is a leading design studio based in Norwich and founded on the ambition to pursue architecture that combines innovative and exciting design with a keen awareness of context and environmental responsibility.

Our response to all projects is characterised by close attention to rich spatial and material qualities, consideration of our buildings’ impact on the environment and a determination to address the ways in which users and clients occupy the spaces we design and reduce their operating costs.

Modece (Modern Design Centre) is an architectural practice with a strong focus on sustainability and social impact. Our work spans architectural design, master planning, residential and community projects, as well as research into material innovation.

We specialise in deep green architecture – using materials with the lowest possible embodied energy and intergrating carbon neutral systems. Our designs respond to seasonal weather variations and climate change through simple yet effective principles such as orientation, mass, solar shading and natural ventilation.  We build with natural materials, including hemp and natural fibre insulations, to create fully breathable buildings that promote a healthier living environment.

Our office is based in the Old Fox Yard, Stowmarket, a Grade II listed 17th-century coaching inn which we restored and adapted during 2020-2021.
