Who we are…
Darren Oldfield Architects is a small award-winning architectural practice established in 2013 and based in West Dulwich

We work with…
A variety of clients including private homeowners, developers and small businesses. Our work is mainly in the residential sector, with construction budgets ranging from £100,000 to over £1,000,000. We believe that good architecture is collaborative a

nd shaped by positive relationships between clients, consultants and contractors. where our projects are… We undertake work all over London and the South East. What we do…
Our core aim is to design and deliver bespoke, carefully crafted buildings that are responsive to the environment, context and brief. We do not have a preconceived style to bring to your project, but an emphasis on light and volume is key to our design process. Light and space are fundamental human needs: even on the most constricted sites, we introduce plentiful natural light through our creative use of glazing & three-dimensional space. We place these concerns foremost through our focus on maintaining an ethical, sustainable approach to design and construction.

Before and after at our Award shortlisted project in Southfields.

A blank brick wall.
Now, a rhythm of timber and glazing glowing onto the street.

A narrow, underused yard.
Now, a crafted brick and timber façade framing light, warmth and family life.

The images say it best. Careful brickwork. Honest timber. Light where there was once shadow. A home that still belongs to its Victorian context, but now lives very differently within it.

From former dairy to the Awards shortlist!

Southfields House began as a dated, compartmentalised corner shop in Wandsworth. Today, it’s a light-filled family home that we’re thrilled has made it onto the shortlist for the RIBA London Awards.

We rebuilt the rear of this Victorian terrace to open the plan and reconnect the house to its garden. A reconstructed brick wing sits alongside a timber-built infill extension.

Together, they honour the original design while introducing something contemporary and low carbon.

Inside, rooflights and a carefully placed picture window draw daylight deep into the home, turning what was once dark and disconnected into a generous kitchen and dining space at the heart of family life.

Sustainability shaped the project from concept to construction. Low-carbon timber structure, a green roof that supports biodiversity, high levels of insulation and a layout reliant on daylight all reduce energy use and enhance comfort.

It’s a project that truly reflects our belief that sustainable architecture should feel intuitive, natural and beautiful in daily life.

Thank you to the team and our brilliant clients; we’re absolutely thrilled with the result and the recognition of the RIBA.

First week back after Christmas.

Office clear-out done, fresh desks, fresh heads, inbox (mostly) caught up. We’ve also had fun reflecting on some of our past projects, work that still inspires us.

We’re looking forward to seeing the projects that are on the drawing board coming to fruition in 2026! We can’t wait to show it to you.

Happy New Year from team Do+Co.

Lisbon on film 📷

To celebrate Rita’s 10 years with us, we rolled up our sleeves and put together a surprise trip to let her know how much she means to us, and Lisbon did the rest.

With the full office joined by previous members of the DO+CO family, Lydia and Jack, we managed to make our way to Cascais and Sintra too for good measure.

Thank you Rita, and thanks for the photos Matt!

“Give us the wow factor and convince us we don’t need to move.”

At this home in Clapham, that meant finding joy in the everyday.

A replacement side infill becomes a new heart to the home: where timber, light and texture create a calm, generous space that opens to the garden.

An exposed lattice roof traces the path of the sun, washing the walls with changing light.
Terrazzo, dark timber and soft plaster add depth and warmth.

A planted pergola outside carries the structure beyond the glass, blurring where the house ends and the garden begins. It also reduces solar gain from the south.

It’s an addition that doesn’t shout for attention. It simply makes staying the more beautiful option.

We’re thrilled to celebrate Matt becoming a newly qualified Architect after smashing his RIBA Part III diploma this month!

Over the past 18 months, Matt has been an important and integral member of our team, overseeing a wide range of projects from conception to completion. His dedication and eye for detail have made a real impact, especially on our Clapham project, which is now nearing completion thanks in no small part to his hard work.

Well done Matt! We’re so proud of you and can’t wait to see what’s next!

10 years ago this week, an architectural assistant called Rita started working for me. Little did I know that she would go on to help shape the course of the practice for the next 10 years.

Together, we’ve built over 80 projects and designed countless more. We’ve grown from 2 staff to 7, moved office twice, rebranded the practice and travelled all over Europe.

The energy, warmth and enthusiasm you bring to the office every day is awe-inspiring, and the practice just wouldn’t be the same without you.

Thank you
