This Half-Height Expansion for a Growing Family in London Is a Real Brainteaser

With their plans to add an additional floor thwarted, BVDS Architects fit a new loft bedroom into a half-height space that feels surprisingly open.

The clients love the community atmosphere of Stoke Newington and wanted to extend their existing home rather than move. The lead architect for the project, George Bradley, lives on the same housing estate and can see the property from his window.

When Andrew and Beth, a couple with a young child, discovered they had a second baby on the way, they realized they needed more space than their much-loved two-story, two-bedroom home in central London provided. Priced out of three-bedroom properties in their neighborhood of Stoke Newington, they called on Bradley Van Der Straeten Architecture to expand their existing home. However, after receiving two planning refusals for a single-story loft extension because it would project above the highest point of the existing roofline, architect George Bradley realized they would need to get creative.

“We decided to approach the design as an interlocking jigsaw,” says Bradley. “We built an unconventional, half-height roof extension and reworked the interior volumes to interlock two floors in the space of one-and-a-half floors and create enough space for the additional bedroom. We may have given less footprint, but we created more volume and an additional bedroom by using the space creatively.”

BVDS Architecture didn’t do any work to the exterior, apart from the box dormer which is clad in tiles to meet permitted development requirements.

    Located on a small lot in Downtown Toronto, the owners of this new three storey residence desired a peaceful urban retreat, purposefully tailored to nurture and enhance a close communal family life and their enjoyment of the outdoors. The response is a highly personalized expression of one small family’s particular lifestyle. At ground level, a back-split condition responds to the natural slope of the site. An adventurous sectional arrangement continues vertically upward, with additional split levels arranged around a 3-storey light well, drawing sunlight (and moonlight) deep into the house. A home office occupies the light well, with views to the living room above, and a library space below. What would typically be the dark middle of the house is bathed in sunlight and enjoys a feeling of expansive vertical space. The various regions of the home are all closely knit together across this interior light well, creating an interesting balance between separation and intimacy: While the family may be individually occupied with remote activities (cooking, lounging, working, playing), they are always quickly and easily engaged with one another. The three principal living spaces (Living room, Kitchen/ Dining area, Library) also expand outwards, into separate exterior areas, each with its own unique and complementary character. At ground level, an arrangement of subtle level changes and low partitions gradually increase the degree of privacy as one moves from the street, through the interior, and into a secluded, forested back garden. The third floor living room – an urbanized version of a cabin in the woods with wood stove and cedar ceiling – nestles intimately into tree tops at one end, and opens widely toward the sky at the other. An upper level outdoor terrace offers easy enjoyment of the city skyline, urban tree canopy, sunsets, and the night sky. The house is thus organized around three principal axes which connect the interior with the outdoors: a ground level Garden Axis, a third level Sky Axis, and a vertical Sun Axis.
