140 Years of Innovation

With a legacy of excellence spanning over 140 years, our journey began in 1883 amidst the bustling industrial landscape of Birmingham. The oldest part of the business, Essex, Goodman and Suggitt, dates back to that very year. HMR Burgess joined our family in 1922, followed by the largest part of the business originating from Kitching and Co in 1900, laying the foundation for what would become DarntonB3. In 2020, we rebranded as DB3 Group.

Over the years, we have evolved into a dynamic, multi-disciplinary practice, expanding our offering and establishing studios across the UK. Our dedication to both people and the planet lies at the heart of our values, shaping our everyday decisions. These principles have significantly influenced our journey, shaping our business and the built environment. Read more about our impact below:

Oliver Essex - DB3 History
Our Journey Begins

In the midst of the thriving industrial revolution, our founding partner, Oliver Essex, embarked on a remarkable journey. It was during this transformative era that Oliver established his inaugural studio in Birmingham, marking the beginning of our story. In due course, the practice gained recognition as Essex, Goodman & Suggitt, extending its presence into offices located in London and Manchester. At a later date, Essex, Goodman & Suggitt were acquired by DarntonElgee, merging to create the entity known as DarntonEGS. A member of the Suggitt family continued to play a vital role in our business until 2022.

HMR Burgess was Founded

The roots of our Welsh origins can be traced back to 1922 when HMR Burgess was established by Haydn Burgess in his Pontypridd studio. After relocating to Cardiff, the practice expanded its reach and began offering architectural services throughout Wales. Through a series of strategic acquisitions, the practice experienced a notable transformation, resulting in a change of name to Burgess Partnership and later evolving into B3 Architects.
