The Practice

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 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 10 years experience within the field of landscape architecture, was joined by Andrew Perrigo in 2006 and Rhian Griffiths in 2007.

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

We believe our 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.
