Alasdair Rankin, managing Alasdair Rankin, managing director, Aitken Turnbull By Scott Wright A HISTORIC Scottish architecture practice has shaken up its internal structure as it plots further growth and signals hopes to expand its team this year. Borders-based Aitken Turnbull, which can trace its roots back to the 19th century turned over more than £1.5 million last year and is aiming to build on that with the restructuring of its offices in Edinburgh, Galashiels and Dumfries. The practice said it has strengthened its leadership teams and hopes to expand its current 26-strong team as workload increases. Projects completed by the practice last year included work on Queen Elizabeth House in Edinburgh, an 18,000 square metre UK Government hub used mainly by HMRC, plus other departments.
