Rob set up Hiraeth Architecture with Michael Plageman in 2019, to focus on the design and development of innovative timber architecture. Although always interested in timber based design and making, this interest took form during his time at the Welsh School of Architecture, where he worked with the university’s Design Research Unit Wales and Welsh woodland charity Coed Cymru to deliver a co-sponsored, design-led PhD, which he completed in 2011. His research explored innovative timber technologies using homegrown Welsh Sitka Spruce, with a focus on the application of modern methods of timber construction to the delivery of affordable housing. This work contributed to the development and certification of construction components and systems and the delivery of several award winning buildings, earning commendation in the RIBA President’s Awards for Research.
As a certified Passivhaus Designer, Rob integrates technical expertise with his passion for innovative and sustainable homes. At Hiraeth, he has delivered benchmark projects such as Tre Ifan and William Ainge Court, both affordable housing developments meeting Welsh Design Quality Requirements and Lifetime Homes standards. Notably William Ainge Court was Hiraeth’s first project to achieve Passivhaus certification.
Throughout his career, Rob has led the design and delivery of new-build, alteration and conservation projects from conception to completion. His portfolio includes a high performance replacement dwelling in the Welsh Valleys, a prefabricated large-span oak visitor building for the scheduled ancient monument of Cleeve Abbey, and visitor centres in Gnoll Park and Pontneddfechan. Beyond applied research in prefabricated system design, he has also led research studies into net zero whole life carbon housing for Wales and optimised retrofit strategies.
Since completing his studies, Rob has maintained close ties with the Welsh School of Architecture regularly contributing as an examiner, critic and tutor.

Chloe is a qualified Architect with SPAB conservation training, joining Hiraeth in 2019. Since then she has lead several key projects in the office across all RIBA work stages and been integral in securing consent for a number of particularly challenging projects.

Chloe’s passion lies in user-centric design, and a carefully researched understanding of place. She combines rigorous problem solving with creative exploration to produce architectural solutions that enhance the special qualities and character of a site, giving careful consideration to each moment the building can offer – such as a view, the quality of light or the touch of materials.
She completed her Masters in Architecture with Distinction at the Welsh School of Architecture and was awarded the T Alwyn Lloyd Memorial, Foulkes Memorial and Wyn Thomas prizes. She has enjoyed returning to the school to support teaching in the second and fifth year studios and the Master of Urban Design course.

We employ all techniques at our disposal to design and convey ideas in a way that is relevant to the stage of the project and to the client. From surveys, hand sketching and physical models to complex 3D computer models, detailed line drawings, computer visualisations, prototyping, and samples boards. This keeps us experimenting, innovating and refining as the brief is ever more defined.
Trust, collaboration, respect and integrity are critical to the work we specialise in and the clients we seek. The industry is often a challenging environment, but we collaborate with manufacturers, contractors, consultants, and of course our clients, to challenge one another to realise the best possible outcomes.
