With experience in both the commercial and residential fields of development
we are confident that we can ensure your project build is a prosperous one.


Red Key Concepts Design & Build LTD is a privately owned, dynamic, forward thinking Construction and Development company based in Whitstable, Kent but covering the whole South East and London.

We pride ourselves on over 15 years of specialising in the Construction Industry to oversee the planning, design and construction of your project from the early ‘ideas’ stage to the end result. We aim to take away the stresses and strains that come with construction projects by offering a proactive and flexible approach, taking the time to plan each project meticulously, ensuring that we work with the client and design team throughout.

Red Key Concepts Design & Build LTD are able to offer the client a traditional Main Contractor or Design and Build service but with a refreshing collaborative approach. We operate a highly professional policy in all aspects of what we do to ensure that the project is delivered as efficiently as possible by our experienced Red Key Team in conjunction with our specialist supply chain.

How we are different:

Sectors and Diversity

We have a wealth of experience of successfully delivering complex development builds within the following sectors; Education, Residential, Commercial and Hospitality. Due to this experience we can offer our clients a plethora of build solutions from day one so that the correct delivery build system is offered. It is our aim to ensure that not only your budget and completion dates but are met but your expectations are managed. Whether it be delivering a commercial unit, a remodel of a car showroom, reconstruction of a classroom block, the design and build of a residential apartment block, restoration and extending a listed building or the remodel and change of use of a hotel to residential accommodation no challenge is too big or small.

Cost Management Procedures and Added Value

It is our intention to provide a dedicated Commercial Team to any project. Any specialist trade packages will be awarded following a strict and robust tender exercise and in conjunction with the Client QS and Management Team. Red Key Concepts Design & Build LTD will offer value engineering advice to the Design Team at every stage of the build and will capture benefits and savings achieved for the project at every opportunity.

Investing in People

It is with pleasure that our Director Charley Gremo-Gilham has recently qualified as our Mental Health First Aider. She has already put in safe guarding procedures to ensure that all staff have the ability to work in safe, comfortable and supported environments to ensure that any mental health needs are met and managed accordingly. This has proved critical in the current National lockdown where we are an industry that has been lucky enough to very much continue.

In addition to this we have gained our Covid-19 Safe Secure office certification for 2021.

We continue to work with, sponsor and support The Lighthouse Club which is the only charity that provides mental, physical and financial wellbeing support to the construction community and their families. We receive no public funding and rely on the generosity of those within in the industry to help us continue our vital work. Shocking statistics show that there is still much work to be done to improve the safety and emotional wellbeing of our construction community.
