BTA Structural Design was formed in 2001 from a previous partnership, Birdwood Trembath Associates, which was based in Chiswick, West London. Our main office is now in a converted barn in the village of Shipton Moyne just outside Tetbury in Gloucestershire, although we still have a presence in Chiswick.
Most of our projects are in London and the West of England, but many are further afield and overseas.
