Bold boldness in design often begins with a simple question: what if space itself could be reimagined? OEB Architects answer with a full-width, blank-canvas extension that transforms a compact north London family home. Rather than the common L-shaped wraparound, they created a generous 30-square-metre addition at the rear labeled A Simple Addition, opening up a new kitchen and dining area for the semi-detached Tottenham house.
Built from affordable, straightforward materials, the extension deliberately sits wider than the original footprint. This choice gives the clients and their two young children a sense of airiness that a traditional wraparound might not deliver, especially given the constraints of a small Victorian terrace. Co-founder David Eland explains that a lower first-floor ceiling on typical outrigger configurations can visually weigh down open-plan spaces, a concern this project sidesteps by extending beyond the outcrop to achieve a taller, lighter interior with a simpler structure.
The property benefits from a long garden, allowing the team to push the extension further back rather than curling it around the sides. The result is a brighter, more open volume that feels less burdened by the original height limitations.
Budget constraints shaped the approach. The designers opted for a modest, shell-like structure that homeowners could finish themselves over time. Walls use painted concrete blocks, while the roof features an exposed timber frame with clerestory windows and a skylight, inviting natural light to wash the interior. The rear facade uses a readily available glazing system, and leftover tiles from another project paved the patio, reinforcing the concept of a weathertight, customizable space for the family to inhabit gradually.
Eland describes the finished shell as a deliberate blank canvas, intended for the owners to complete at their own pace as life allows. The pared-back materials—painted blockwork walls, a warm linoleum floor, and an exposed timber ceiling—provide a robust, low-maintenance backdrop for the everyday rhythms and occasional chaos of family life.
Redesigning the extension also enabled a reconfiguration of the rest of the house. The bathroom moves to the center of the plan, and the staircase now runs lengthways rather than across the footprint. Notably, no room doubles as a corridor in the new layout, and the children’s rooms are fully separated rather than interconnected, signaling a future-ready plan that can adapt as the family grows.
The studio hopes this approach makes the home easier to adapt over time, while preserving a flexible, almost warehouse-like vibe in the open-plan area connected to the entrance via a long gallery. As the children mature, Eland envisions the open spaces taking on more defined, built-in roles, reflecting evolving family needs.

What do you think about choosing a wider, single-block extension rather than a traditional wraparound? Are there scenarios where you’d prioritize a taller, lighter interior over maximizing the footprint?
