What We Do

The prospect of the design, planning and construction of a project can be daunting. 

At healycornelius, our approach is to make all the processes involved simple to understand and explain which permissions are required to realise the project. We adapt our services on each project according to your needs, whether you want to be actively involved throughout or play a more passive role once design has been agreed.

About Our Services

Who We Are

Formed in 2004, healycornelius design has developed an architectural, technological and design practice to serve a growing client based for projects in the South East of England and South West of Ireland. 

The practice has grown steadily, nurturing a strong team of architectural technologists and designers who create solutions and deliver consultancy services to private  and commercial clients, architects, contractors and interior designers.

We were introduced to healycornelius design ltd. by our freeholder when in initial discussing creating a cinema space in the basement of our premises. At our initial meeting, we discussed various aspects relating to the proposed layout, construction challenges and permissions with Niall which resulted in a significant change to our proposals and, in turn, a significant improvement to the design and capacity of our premises. healycornelius worked with us to secure all necessary approvals and licenses for the performance of film and sale of alcohol. Architectural and Technical Designs were provided by healycornelius without which we would not have been able to deliver the very successful premises that we offer our patrons to-day.

We were recommended Niall (Healy) by a friend who had worked with him directly. He and his team helped us with a two storey extension and loft conversion to our Victorian house in London. A real strength of this practice is an ability to cover all aspects of the project and get into any detail necessary with the building contractor, such as the construction methods to be used. This gave us a lot of confidence that things were being down correctly and helped achieve quick solutions when the inevitable questions and issues came up during the project.
