The Team Behind Alchemi Renovations
Over 25 years of combined experience delivering design-led, sustainable residential projects across prime central London.
Laura Marino and Charlie Baxter — partners in life and business — co-founded Alchemi Group, a multi-award-winning development management company that set new standards in design-led residential delivery across prime central London, with a portfolio valued at over £1 billion at peak.
During their restoration of the Grade II-listed Westminster Fire Station, a major flood revealed how vulnerable even landmark buildings are to a changing climate — confirming what their years of experience had already shown them: London's private housing stock needs the same calibre of expertise historically reserved for large-scale development.
They founded Alchemi Renovations to bring that expertise directly to homeowners — making the process clear, coordinated, and design-led. Laura also leads Studio L London, an award-winning interior design studio dedicated to creating beautifully sustainable, narrative-driven living environments.
