Speirs + Major is an award winning British design practice that uses light to enhance the experience of the visual environment. Our work is wide-ranging in terms of type and scale and encompasses architecture, strategic branding and innovative product design. We have been credited with helping to raise awareness of the lighting design profession globally. Today we employ 30 people drawn from disciplines including architecture, art, interior design, lighting, graphic design and theatre. Our offices are based in London and Edinburgh, UK.

We work in close collaboration with our clients and their architects and designers, using light to reveal the core principles of the design while integrating light into the final built form. As lighting architects, we develop environments where light is an integrated part of the final built form. We combine creativity with pragmatism ensuring the client's lighting solution is both sustainable and easy to manage.

This approach has guided us through hundreds of successful lighting projects around the world, including for One New Change, London; Barajas International Airport; the Grand Mosque of Abu Dhabi; the Sackler Crossing and Royal Botanic Garden at Kew; Copenhagen Opera House and the interior of St. Pauls Cathedral, London. Our list of collaborations includes projects with Ateliers Jean Nouvel, John Pawson, Fuksas, Peter Marino, BIG, Wilkinson Eyre Architects, Allies & Morrison, Foster + Partners, Rogers Stirk Harbour + Partners, Grimshaw, and numerous others.

We use light to help create visual narrative after dark. We have helped evolve lit identities for projects for leading clients including Nokia, Sony, Virgin Atlantic, IBM and the BBC to enable them to extend their presence after dark.

We have also developed strategic lighting masterplans for many cities including Cambridge, Coventry and Durham and light strategies for private developments such as Kings Cross, London, Greenwich Peninsula and Saadiyat Island, Abu Dhabi.

We have designed many successful products for our clients, ranging from carefully crafted one-off light sculptures to mass-produced commercial lighting systems. Our clients benefit from our long experience of working with light in partnership with industry – recognising the need for new products and identifying gaps in the market. Our designs seek a special harmony between the quality of light, the form of the object and sustainability of technology used.
