Over the past 25 years Mark has gained vast experience and expertise working on various projects throughout Northern Ireland from managing construction projects, designing projects and building projects for clients.

Why choose us?

This is a very good question. Throughout our career we have heard and witnessed numerous occasions where projects have faltered on the overlap of responsibility. In fact this is one of the main reasons for court cases in the construction industry.


Architects understand design but lack on site construction knowledge!


Building Contractors understand construction but lack Architectural knowledge!


Energy Assessors understand epc software but lack architectural & construction knowledge!


Thermal Imagers understand photographs but lack real life understanding of buildings!


Why would you use several companies and walk into the mistakes that happen in the overlap between each area instead of using one place whose experience covers all these points which is directly relative to the success of your project ?


Architectural Design Services – one stop for all your expertise.
