We are a meeting point for projects around the world. We are design-led and research-orientated. Also, we are critical about what we do. But we have lots of fun as we love the challenge of the craft of building.


We are qualified architects, professional researchers and teaching architecture at university level. We are also members of the RIBA validation board for architecture schools and selected as one of the London practices in the RIBA mentoring scheme for university students.

But above all we are committed to design, detailing and materiality.

Our studio is based a former Pye Electronics building in West Dulwich and our window overlooks the West Norwood Cemetery.

Our work has been published by Dezeen, The Guardian, Homes and Gardens, Axxis, The Scotsman Magazine, Evening Standard, and The Architects Journal.


A Small Studio Ltd. was founded in 2011 by Helena Rivera. Helena trained in architecture at University College London and the Royal College of Art. She is a fully qualified Architect registered on the Architects Registration Board (ARB) and chartered with the Royal Institute of British Architects (RIBA). Helena is specialised in the British planning system and has a Doctorate (PhD) in Regional Planning from the Bartlett School of Planning (UCL).

Before setting up A Small Studio Ltd., Helena worked at Alsop Architects on the Rotterdam masterplan and later on The PuBLIC, a Lottery-funded arts centre in West Bromwich. Working with Will Alsop and his team inspired her to promote a multidisciplinary, flexible and non-conventional approach to work. Helena is deeply committed to research, experimentation and materiality.

Helena grew up in the Netherlands and has always ridden a bike in the city. She is actually Colombian and takes her black coffee seriously. She has lived in London 20 years and loves the city.


Rebecca joined A Small Studio Ltd. in 2015. She completed her RIBA Part 1 studies at the University of Portsmouth in 2011 and was nominated for the RIBA Bronze Presidents Medal. During her year out, Rebecca was employed by dRMM where she worked on educational projects. She was also employed by Hawkins\Brown as a team member of the Crossrail proposals at Liverpool Street Station. Rebecca returned to finish her RIBA Part 2 at the Bartlett School of Architecture (UCL). She completed her Masters with Distinction in both Design and written Thesis with an investigative focus on the social and cultural implications of residential estate redevelopment.

Teaching is important for Rebecca. She is currently a Design Studio Tutor for third year undergraduate architecture students at the University of Portsmouth. In addition to her love of strong Colombian coffee at the small studio, Rebecca loves being kept busy with the renovation her new house. And pouring concrete. Rebecca loves concrete.




Kalliopi ‘Bouz’ joined A Small Studio in 2017. She grew up on a Greek island, drawing classical columns since an early child. At the age of 18 she moved to London where she completed her RIBA Part 1 in 2013 at Kingston University. During her year out, Kalliopi worked at Mappamundi Design on projects in both London and Nigeria. Kalliopi returned to finish her RIBA Part 2 at The University of Edinburgh where she graduated with a Distinction for her thesis project and dissertation. Her dissertation was written on the conflict between hand drawings and computation systems techniques used in the act of drawing today.
And although Kalliopi loves hand-drawings, she is a wizard at 3D computer modelling because she acknowledges that we should adapt to our changing reality. The perfect bridge between hand drawing and computer modelling is, in her eyes, physical model-making.


Kalliopi is passionate about her reading and writing. She likes walking around the city of London with a sketchpad in her bag and is always on the lookout for new columns to sketch.




We like working and collaborating with people.


We take pleasure in interpreting the client’s design brief.


We don’t see problems, we see challenges.


We enjoy working with materials: how they are made, where they come from, how they can be used and re-used.


Our projects are in the detail. But we never lose sight of the bigger picture.


We ring-fence an element of each project and don’t interfere with its budget.


Our work ages gracefully. Whether it is a 2-week installation or a building for life.


We love our planet and we want to respect it.


Our projects are biased towards the socially inclusive, accessible and age friendly.


We see beauty in diversity. We like working with different scales, different people and in different contexts.
