Justin is a graduate of Dundee University where he specialised in Sustainable Design before gaining extensive international experience in New York and Dublin. As an architect and innovator, Justin has successfully led design and development teams across hospitality, commercial, residential, and large-scale master-planned communities.

Recognising the urgent need for more efficient, sustainable, and scalable construction solutions, Justin co-founded HTL.tech, a 3D construction printing (3DCP) leader. Under his leadership, HTL.tech has pioneered the integration of standard ready-mix concrete into 3DCP in Ireland, completing Europe’s first 3D-printed social housing scheme using this method. He works closely with industry leaders, government agencies, and academic institutions to promote construction technology, establishing 3DCP as a supportive tool in contemporary building practices within the Irish and UK sectors.

Committed to socially and ecologically conscious development, Justin continues to push the boundaries of innovation in architecture and construction, ensuring that additive construction technology serves both industry needs and societal progress.
