Behind a London Terrace, A Glass-Lined Addition Connects the House to the Garden

On a quiet street in North London, a typical terraced house has been carefully reworked to support the rhythms of modern family life. Designed by Cairn Architects, the project pairs a contemporary brick extension with a thoughtful interior refurbishment, transforming the home while respecting the structure that was already there.

The goal was straightforward. Create an open plan living space where the family could gather, relax, and spend time together. Rather than forcing a dramatic change all at once, the work was completed in stages. This approach allowed the project to meet time and budget limits without sacrificing the quality of the materials or the details of the design.

At the rear of the house, the new extension introduces a calm family space that feels closely connected to the garden. A full glass wall framed in black steel opens the room toward the patio outside, where a seating area and outdoor kitchen with a barbecue extend daily life into the open air. The connection between inside and outside feels immediate, turning the backyard into a natural continuation of the living space.

Step indoors and the effect of light becomes clear. Multiple skylights are positioned overhead, working together with the glass wall to fill the new addition with daylight throughout the day. The natural light settles across the open plan layout, where the living room, dining room, and kitchen flow into one another without interruption.

Contemporary furnishings help define each area, while a micro cement floor stretches across the space to tie everything together. The continuous surface adds a quiet simplicity to the interior, allowing the light and materials to take the lead.

The kitchen sits just beside the living and dining areas, forming the practical center of the home. Here, dark cabinetry creates contrast against gray marble countertops, while brass fixtures introduce a warmer tone. The combination feels both modern and durable, designed to withstand the daily routines of family life.

At the far end of the kitchen, a walk in pantry sits behind a glass wall. The pantry acts almost like a light box within the plan. Its transparent surfaces allow daylight to filter deeper into the house, while full height glass doors illuminate the back portion of the kitchen.

Beyond the new addition, a hallway and staircase lead into the original areas of the house. These spaces were not simply updated but carefully restored. Natural materials were selected for their durability and long lifespan, giving the older parts of the home a renewed sense of strength while maintaining their character.

The original parts of the house were carefully restored with long lasting natural materials that complement the new extension.

One of these restored spaces is a secondary living room that also functions as a home office. A fireplace anchors the room, offering a more intimate atmosphere that contrasts with the openness of the extension. Above the office, windows allow light to pass through an internal opening and into the pantry below, creating another subtle link between the old and new sections of the house.

Upstairs, the bedroom continues the calm palette found throughout the project. Gray walls are paired with crisp white trim and classic window shutters, producing a setting that feels quiet and balanced.

The bathroom follows a similar approach to material and tone. Gray stone tiles cover both the floor and the walls, giving the room a solid, unified appearance. Inside the shower, three built-in niches provide practical storage while maintaining the clean lines of the space.

With careful restoration, durable materials, and a well planned extension, the home now balances its historic structure with spaces designed for contemporary living.
