The London House with a Secret Basement, Double-Height Courtyard and Green Wall

by modernarchitectblog_admin

In north London, a once dark and divided 1930s home has been completely reimagined into a light-filled sanctuary for family life. Designed by Mulroy Architects in collaboration with Nichola McKerrow Todd, founder of No Ordinary House, the project balances warmth, function, and nature at every level. What was once an outdated five-bedroom house is now a flexible four-storey home centered on connection—to light, to landscape, and to each other.

Like many homes of its era, this double-fronted property had suffered years of poorly planned additions. The result was a maze of narrow rooms that blocked sunlight and disrupted the natural flow of the house. When Nichola and her husband Stanton purchased it in 2021, they saw potential in the layout but knew it needed a total rethink. With two teenage sons and a love of entertaining, the couple dreamed of a modern, social home that could evolve with their family.

After

The redesign began by opening the house to light and nature. The existing extension, which had once created a physical barrier to the garden, was replaced with a bright, fluid addition that transformed how the family lives. The new structure established strong sightlines, from the front door to the garden’s edge, and introduced generous glazing to bring the outdoors in.

Stepping through the front door now reveals a sense of openness that didn’t exist before. The restored original staircase anchors the foyer, drawing the eye upward toward the light that filters through the new galleried stairwell. To one side, a sitting room retains a sense of the home’s original character, blending soft neutrals with tactile finishes.
