Crafting Extraordinary Spaces

Cousins & Cousins, founded in 2012 by Ben and Jelena Cousins, is an architecture and interior design practice dedicated to creating high-quality homes, workplaces, commercial buildings and cultural projects. Our work is focused on using materials, light and detail to craft spaces that promote wellbeing for the people within them.

Conversation is at the centre of our practice ethos. We establish what’s important to our clients, to unlock the potential in their projects, give them spaces that exceed expectations and maximise value and enjoyment.

Our buildings function as beautifully as they look, uniting carefully composed spaces and simple form with quality and sustainability, to push boundaries in design. Our process is collaborative and iterative, and we are continuously imagining and reinventing ideas to define creative design solutions.

Alongside our expertise in new-build homes and private commissions, we are also specialists in sustainable retrofit, modern methods of construction, heritage sites and listed buildings.

The practice is RIBA accredited and ISO 9001 certified, with risk management and mitigation woven into every stage of our methodical and transparent design process, supplemented by rigorous monitoring and robust procedures.

We are committed to providing an outstanding service with a collaborative and personalised approach that will always delight our clients.
