About Us

Who are we

We are experienced architects based in Cornwall, with a focus on providing cost effective design services for small residential projects, including one off houses, annexes, loft conversions and extensions.

We work closely with our clients throughout the process; using creativity and experience to cater to individual tastes, budgets and functional needs.

In contrast to traditional architectural firms, DesignStudioSW has been streamlined with small residential projects in mind. We’ve abandoned our dedicated office, discarded our shirt and ties and chosen not to renew our architectural qualifications in order to save £000’s on overheads. This prevents costs from being passed on to the client, allowing us to deliver architecture at a quality you never thought you could afford.


We’ve been around for 145 years as chartered architects and have changed a lot over the years. Trading under Silvanus Trevail from 1871 – 1903, Alfred J Cornelius, 1903 – 1964, Alex Wells 1964-1999 and A4 Architects from 1997- 2016. We’re used to adapting with the times, which is why we decided to form Design Studio South West, after recognising the need for quality, cost effective architectural services, that are affordable for residential projects.
