Aurore Baulier made her architecture degree in Brittany and her masters in sustainable architecture in Gothenburg, Sweden. Back in her native France, she was a member of Louis Vuitton’s in-house architecture firm when Barber & Osgerby lured her to their Universal Design Studio in London. It showed a good move: a years later on, Aurore runs her own RIBA-chartered London practice, Atelier Baulier, concentrating on sustainable design (Aurore also occurs to be a certified PassivHaus Designer).
Among the firm’s current tasks, a West London house upgrade for a family of 4, caught our eye thanks to its well-restored Edwardian exterior and back extension with a gleaming sawtoothed roofline. Aurore explains the overhaul as a “low-carbon deep retrofit highlighting the use of natural products as a new standard.” Believe concealed features, such as wood fiber insulation and a heatpump in the garden, in addition to generous brand-new living spaces with lime plaster and stained plywood surfaces, and a great deal of natural light. We’re not the only ones who have born in mind: your home has actually been chosen for ArchDaily’s Building of the Year 2026 and shortlisted for a RIBA London award. Join us for a look around.

Above: The semidetached, turn-of-the-century structure remained in a moldering state when Phoebe and Paul Sprinz purchased it (scroll to the end to for a glance as it was and some in-progress shots). The household had lived close-by and liked its location and original detailing, but they required more space and focused on an eco-minded technique. 
Above: The period front door and glazed tiling were restored and the outside is now ended up with Brouns & Co. linseed oil paint, an age0-old, resilient, permeable option made from flax seed. 
Above: Out back things zig and zag. The multi-story addition houses a brand-new kitchen along with a lofty, two-bedroom attic for the family’s 2 teens. The jagged roof lines led the designers to call the task Twin Pitches.
Aurore writes: “The inverted double-pitch draws inspiration from the geometry of the original outrigger, replicating its 22-degree slope. The brand-new roof shifts upward at a 55-degree angle opposite the existing slope, producing a striking double-peak shape.” The extension has a lumber frame and is ended up with salmon-colored lime render from Lime Green. The tiles that wrap around the base work as “protective skirting, safeguarding the lime render from water splashes while including visual richness and connecting into the green tiled foot of the front door.”
