THA was founded in 2002 by Timothy Harris.

Initially specialising in carefully designed private houses, the company has expanded to include chateaux, apartment blocks and holiday complexes.


It has established a reputation for realising projects in particularly sensitive environments.

This includes Unesco sites, conservation areas, working with listed buildings and national monuments.


The primary tenet is that powerful architectural concepts can reconcile conflicting interests with diplomacy to produce highly responsive buildings.  A deep understanding of the demands of all parties is the seed from which real architecture is generated.


The underlying philosophy of THA is the creation of a sustainable architecture.


Over the years we have developed project management processes which enable our clients to be fully involved and make informed decisions every step of the way.


Tim Harris developed a passion for Architecture from an early age and won a national design competition at 19. He went on to study architecture at Edinburgh University and qualified with an MA specialising in renewable energy and intelligent buildings, followed by a diploma in Architecture.

Tim has worked in architectural practices in Sidney, Belfast, Paris and London, before setting up his own in 2001.

He has run projects varying from hospitals and supermarkets to housing developments, as well as private residences with environmentally-friendly aspirations.
