Klas Hyllén Architecture

We make architecture with a Scandinavian touch


Great architecture provides spaces where we’re effortlessly at peace, making time spent with those around us more meaningful. In every project that we take on we seek to make buildings that will enrich the lives of our clients providing comfort, joy and beauty in all that we do.

Our architecture is rooted in an ethos of simplicity with a high attention to detail, light and material choices and we love to celebrate good craftsmanship and connections to nature. We listen carefully to our clients and try to respond with purpose to their requirements – always seeking to be ambitious, providing a high-quality service and giving our clients more than they expect.


“We are very impressed by the plans for the new house and the artist’s studio. This is a thoughtful and conscientious proposal which incorporates the best of modern architecture and eco friendly aspects. We love the fact that it is a passive house which sustains itself without drawing on external resources. It is exciting and admirable; a dwelling and studio which Whatley can take pride in. The juxtaposition of the beautiful old houses in Upper Whatley and the radical new Clear View will be stunning.”

Neighbour – Haha House

“We have worked with Klas on a mews in Edinburgh and a terrace in London. He has transformed the spaces, bringing light and an amazing knowledge of shapes and materials. His professionalism and attention to detail works really well with builders and neighbours alike. Best of all, he is an absolute pleasure to work with – simultaneously a great listener and suggester. A superb all-round architect.”

Client – House Designed around a Table

“The quality of the design service was fabulous. Everything was made as simple and clear as possible and done in a friendly and professional way.

I would totally recommend your design service. I have had so many positive comments, lots of ‘wows’ and shock when people see the changes that have been made to our home. The design has totally changed our home and made it a more attractive and sociable place to live. We now have enough space for visitors to stay over and life is more comfortable.”

Client – House with a Pink Door

“When we first asked Klas to design our two storey extension and reconfigure our existing house we had no idea how amazing the finished project would look. Rather than a standard box addition to our Edwardian house, we now have a stylish contemporary home which seamlessly links the old and new whilst creating wonderful open plan spaces with the natural light we were craving.

We especially love the unique window design and vaulted ceiling in our master bedroom which makes it feel so spacious and rivals even the best hotel rooms we’ve stayed in. The kitchen space is perfect for family living and the bespoke bi fold doors designed to be full height mean that the garden feels part of this fantastic space and is perfect for entertaining.

In addition to all of this, the specification is second to none and gives the detail of the finished product a sleek and refined finish.

We can’t thank Klas enough for the huge amount of care and attention to detail he has given our project in seeing it through to completion. Klas truly has gone above and beyond our expectations and we adore our new home.”

Client – Shadow House

“As the primary Architect and Project Manager for the Boardman Performance Centre fit-out, Klas really did deliver on every level.

The vision and ambition of the team was fully understood by Klas right from the initial briefing. Klas’ passion and determination to bring the Boardman brand values to life, through the building’s design, delivered a final building that not only excites the senses but embeds the foundations and philosophy of the brand at it’s heart.

As was to be expected with such a revolutionary, first of it’s kind project – the journey was not simple – with many challenges and unexpected turns encountered through the 3-year life of the project. Klas’ determination to deliver the best possible solution at each stage helped to steer the wider project team, whilst his in-depth knowledge and ability to respond to potential issues was invaluable in re-defining the approach as the project progressed.

It was an absolute pleasure working with Klas on this landmark project and the Boardman team can’t thank him enough for his determination and contribution. The final building is testament to his passion and skill as an Architect.”
