Proper, careful installation is vital to the success of any project, so I need to be involved.
I lead my own installation team. Some of my furniture is quite complex it's best fitted by the designer, and that's me
However, I don't undertake building work or decoration, and I call in specialists like electricians, plumbers or gas installers as required by safety and legal considerations. If you have builders working for you I liaise with them on these and all other aspects
Because I'm providing a handmade, high-quality product I very seldom work on a 'supply only' basis, not least because I can't back up the total package if I've only done part of it
Above all, from your point of view it makes sense to have one point of contact for all decisions or queries, or for any problems that might arise
