Pitched Passivhaus
Somewhere deep in the conservation thickets of southeast London, where solar panels are eyed with suspicion and chimneys must do more than merely suggest vertical aspiration, sits Pitched Passivhaus: a project that plays by the rules of the Dulwich Estate, while quietly rewriting them.
RDA Architects’ new-build home replaces a weary 1930s house with something far more complicated.
The street-facing elevation is a well-mannered composition: pitched roofs, tall chimneys, and a rather beguiling perforated brick screen that nods to the Arts & Crafts masters. There’s something of Baillie Scott in the balance of mass and ornament, a hint of Voysey in the simplicity of the roofline, and even a restrained echo of Lutyens in the way brick is used not for show, but for depth and shadow.
Go around the back, and the house drops the costume. Here, the architecture stretches out: triple-glazed sliders, open-plan living, and a garden that flows straight from the kitchen. It’s not a surprise, but it is a relief. This is a house with two faces, both entirely convincing.
Inside, the spatial choreography is subtle and assured. A bold black balustrade runs alongside a central stair flooded with light, the kind of space that makes you pause mid-step just to watch the way morning sun slides across the timber. Understandably the owners are thrilled with their generously proportioned, light filled new home.
There are no obvious eco-gestures, no leaf sculptures to hammer home the point. Instead, systems are buried in plain sight: solar panels tucked invisibly between pitched roofs, chimneys that double as service stacks for the MVHR and heat pump, and a quiet whirr of smart tech doing the hard work of keeping air fresh and temperatures constant. It’s architecture as passive performance.
The perforated brick screen, that moment of texture on the front elevation? It’s not just a visual device. It veils the master shower, allowing occupants to see out without being seena literal instance of Arts & Crafts privacy, the hand-made made high-tech.
Photographing the house feels like tracing a line between two centuries. One moment, you’re aligning a shot where brick modulates light in a way Philip Webb would have admired; the next, you’re ducking a drone to capture a roofline calibrated for solar gain and summer shading. The irony is delicious, and the craft is real.
The architects call it a dual-faced design, but that undersells it. This is a house with a quiet dialectic—context and performance, tradition and tech, Dulwich and Dudzicki. And yet nothing feels compromised. Well mannered to the street, while joyfully celebrating the sun in the garden. Pitched Passivhaus deserves credit for doing something hard: paying attention, to its neighbours, to its occupants, and to its carbon footprint.
