T-Space is a full service architectural and engineering practice.

As 'Principle Designers' we provide the leadership and expertise to drive projects from concept to completion.  Clients bring us their aspirations and we bring the team. 

The expertise at T-Space has taken years to assemble.  To carry a project from concept to completion demands a wide range of skills, a wider range than any one person can embody.  The creativity that launches a project is a very different skill from the doggedness that will overcome the statutory hurdles or the discipline required to manage the project program.  So the best outcomes demand the best team.

T-Space works mainly across Essex, Hertfordshire & London.
