"We really enjoyed working with Alter & Company. Grant and Leith worked really creatively with our limited budget, injecting lots of vision and excitement to an otherwise ordinary project and going the extra mile when needed"

Adam Joolia

“A heady combination of creativity and collaboration with a healthy dose of practicality and a keen eye for process makes Alter & Company”

Mark Howard, Duke of Soho

"Highly recommend Alter & Company for the work that they have designed, delivered and completed at the Science Museum and the National History Museum London. Alter & Company has a great ability to not only be the designers and ideas people, but the coordinators on projects; they are very good at making buildable and considered detail decisions"


"Alter & Company have been a pleasure and an inspiration to work with on our extensive restoration project. They quickly understood the brief and the people behind it, and have consistently challenged us in terms of structural ideas, materials and elements, consistently going above and beyond"

Jane Fordham & Craig Bonner, Stanyards Farmstead
