Castellum London (UK) Limited have been working closely with ATI on projects in London and the Home Counties for the last seven years. Throughout this time we have built a great relationship with Matt, Kevin and the team.

We have the trust and confidence in ATI to deliver our most prestigious developments, they are our first choice now and their wide variety of solutions avoids the need for multiple subcontractors. Throughout the build they demonstrate a positive, can do attitude, and their aftercare following PC is exceptional.

We currently have ATI on site in Wentworth on a £20m build - they are on budget and programme. Recently completed projects involving ATI include a complex ten apartment fit out in Chelsea and a modern new build in Kingston.

We recently engaged ATI to undertake the electrical, lighting and AV installation for the fit out of a luxury Chelsea penthouse. The client was eager to maximise the end user space and minimise service cupboards and plant space. This placed high demands on ATI to work closely with us and the services team to coordinate their installation and they met this challenge with enthusiasm.

The project management and ‘can do’ approach throughout was excellent and we are looking to build upon this relationship with ATI moving forward and work on many more projects together.
