Tirlun Design Associates

TDA, the trading name of Tirlun Design Associates Ltd, is an innovative, design led and dynamic landscape architectural consultancy.

The practice works from a purpose built design studio set in its own 2.5 acres of organic farmland and orchard in the heart of The Vale of Glamorgan, South Wales.

The company was originally established in 1998 and was incorporated as Tirlun Design Associates Ltd (TDA) by director Rhodri Crandon in 2001.

Rhodri, who has over 15 years experience within the field of landscape architecture, was joined by landscape architect Andrew Perrigo in 2006 and assistant landscape architect Hannah Stracey in 2012.

The practice has a wide range of experience working in multi-disciplinary teams, which due to the nature of many projects, results in close working relationships with other consultants.

The company’s success is based on understanding the needs and aspirations of the client, whilst accommodating the end user and producing inspired, practical and environmentally sustainable landscape design solutions of high quality.

The practice is supported by a network of specialists and sub-consultants.
