Winston Road, London N16 - Rear Extension
The Victorian terrace is one of Stoke Newington's defining building types. Deep plans, generous room heights, beautiful proportions at the front - but dark, cramped kitchens to the rear, disconnected from the garden behind. It is one of the most common briefs we receive across N16, N4, and Hackney: how do you open a Victorian house up without losing what makes it special?
Scallop House, Winston Road N16 - the rear elevation from the garden. Curved lime render columns frame full-height glazing, opening the Victorian terrace to the south-facing garden
At Scallop House on Winston Road, the clients wanted a kitchen and dining space that genuinely lived with the garden. Something that brought in light, welcomed the outdoors, and felt considered. They wanted something bold - something that wouldn't pretend to be anything other than what it was: a piece of contemporary architecture growing from the back of a 19th-century terrace.
We weren't interested in a glazed box. Glass disappears. We wanted something that would cast shadows, gather light, and age well - like the house behind it.
Curved Forms, Drawn From Landscape and History
The form draws from two sources simultaneously: the plasticity of traditional render buildings - the convents, baths, and civic structures found across Southern Europe - and the natural language of the garden itself, where nothing is truly straight. Curves are how living things grow.
The cylindrical columns and full-height arched window that define the garden facade. Lime render, hand-applied in a warm terracotta tone
The exterior is finished in a warm pink-terracotta lime render, hand-applied in a textured manner that reads differently in morning and evening light. This is not flat colour. It is a material with presence: porous, tactile, and connected to the ochres and siennas of natural earth pigments. The scalloped, cylindrical forms that give the project its name emerge from the garden boundary like something uncovered rather than built - organic, considered, and unhurried.
Three cylindrical columns anchor the composition. Between them, full-height glazed openings fold the garden inward. Above, an angled roof plane - punctured by two elliptical rooflights - rises to meet the Victorian parapet behind, creating a cross-section that is part chapel, part orangery, entirely itself.

Sustainable Architecture Is Not an Afterthought
As a practice with Passivhaus expertise, our approach to sustainability is always fabric-first. Before specifying a single piece of plant or renewables, we design the building to perform.
Looking into Scallop House from the original house threshold. Two elliptical rooflights puncture the vaulted ceiling, drawing afternoon sun across the kitchen and polished concrete floor below.
At Scallop House this means high levels of insulation to the roof and floor, carefully detailed thermal breaks at the junction with the existing house, and glazing specified for solar gain performance - not just appearance. The rooflights are positioned precisely to maximise winter solar gain while limiting summer overheating. The thick render walls provide significant thermal mass, absorbing heat during the day and releasing it slowly through the evening.
The lime render itself is inherently sustainable: breathable, low-embodied-carbon, repairable, and durable. Unlike cement-based finishes, it can be maintained and re-applied by hand. It will not crack and trap moisture. It is, in every sense, a fabric-first material choice.
Afternoon light rakes across the terracotta render walls and pink concrete floor. The elliptical rooflight and garden-facing doors keep the space connected to sky and landscape throughout the day.
Everything in Its Right Place
Inside, the material logic stays deliberate. Render continues from outside to in, wrapping walls, sills, and built-in bench seating in a continuous warm texture. The floor is polished concrete in a complementary tone. Against this background, three elements provide contrast: pale oak timber window frames, a crisp white kitchen island in honed stone, and - as a single note of punctuation - a red lacquered structural column marking the junction between old and new. That column is a small but important signal: this is a contemporary addition, in genuine dialogue with the house it joins, not disguised as something it is not.

The blue bathroom above - reached through the upper extension volume - operates as a complete counterpoint. Deep cobalt render, a large roofscape window, a single timber vanity. A room designed to feel like being inside the sky.
What Scallop House Proves About Extensions in N16
Stoke Newington and Hackney have a planning culture that values considered, high-quality design. Unlike some boroughs, Hackney planners will engage with genuinely contemporary proposals on Victorian terraces - provided the approach is well-argued, contextually literate, and materially resolved.

Scallop House demonstrates that a rear extension in N16 does not have to be a cautious, historicist addition. It can add genuine architectural value. It can be something that, in twenty years, people are no longer sure was not always there - because it feels, in the best possible way, like it belongs.
