“Preserve and renovate” has been a bit of a Treehugger mantra for years. The idea stems from the fact that all those embodied carbon emissions (also known as embodied energy or upfront carbon) are already locked in an existing building. All that embodied energy would go to waste if one were to demolish and build anew, meaning that preserving and upgrading a building is a far more energy- and carbon-efficient option.

In the case of one family living in a south London neighborhood, preservation and renovation were the way to go when it came time to revamp their home. The family opted to thoughtfully renovate and extend their Victorian-era maisonette with the help of local firm Nimtim Architects. Aiming to strengthen the connection between inside and out, the skylit rear extension that opens to the home’s backyard now makes it feel much more open.

The new scheme includes an open plan kitchen, dining, and living room in this rear addition, enlarging this lovely small house from a modest 968 square feet to its current size of 1,248 square feet. As the architects explain:

Dubbed “Walled Garden,” the project features an earthy palette of natural materials like Douglas fir for the exposed beams, warm-colored tiles in the dining area, and rough plaster on the walls. The stainless steel surfaces of the kitchen offer a striking contrast to these, while also providing a glint of reflected light in the deeper recesses of the home. As the designers note, these were deliberate choices to highlight certain aspects of the client’s lifestyle:

The view as seen here extends right through most of the house, with the overhead skylight offering the serenest of lighting over a down-to-earth yet refined interior. The existing brick wall that inserts itself into the scene is skillfully emphasized by a line that the architects carry into the inside of the home:

The front part of the maisonette has been readapted as a guest annex with its own entrance and kitchenette. Such a layout means that the home could also be reconfigured as an intergenerational residence in the future, where elderly grandparents or young adult children might live.

Upstairs, we find the two bedrooms, and a bathroom.

The master bedroom itself has a lovely view, which can be found by way of a small balcony that overlooks the extension below.

The bathroom upstairs also follows much of that down-to-earth palette, using light-colored tile, stone, and lots of natural light to create a contemplative atmosphere in which to relax and unwind.

Most crucial to the renovation is how the exterior landscaping has been redone to establish interesting points of view, as well as to evoke a sense of peaceful calm:

With water, sun, and plant life all carefully considered in this unpretentious renovation scheme, a small house is made to feel larger and much more integrated with its surroundings—without having to build something new and potentially more carbon-intensive. To see more, visit Nimtim Architects.
