What Our Clients Say About Us

Much of our work comes from referrals and returning clients who trust us to deliver time and again. Their words reflect the care, quality, and consistency we bring to every project.

Stone Street Interior

Landseair Developments has undertaken a series of renovation projects for me and I have no hesitation in recommending them. I have valued their commitment to doing a quality job, their depth of experience and problem solving abilities, critical when dealing with old buildings and conversations. I have found them at all times to be honest, decent people who operate in a spirit of teamwork with the client and architect.

Hilary Denby-Jones

Stone Street, Sevenoaks

I am happy to give my full endorsement of Landseair Ltd. From start to finish the team were punctual, reliable, professional and able to pivot with the inevitable challenges that turn up when completing a substantial building project. They were also clean, tidy and well-mannered throughout. We are a happy customer.

Alex Woodward

CEO of Walton Heath Golf Club

Landseair Developments completed this successful project by working closely with HMY and the client to a achieve a quality development with an environment of a working Golf Clubhouse that required specific access at various times during the construction work for international golf events and competitions. Their consideration and respect for the client was instantly recognised and maintained throughout the construction period and members and visitors are now enjoying this new facility. HMY have worked with Landseair for over 20 years and have no hesitation in recommending the quality of work and consideration for client needs.
