Expert conservation architects agree: the key to preserving a historic building is occupancy. Diligent homeowners, like the Barrows of Co Antrim, are often the first to notice and fix minor issues like leaky downpipes, preventing major damage.

But what happens when an old home needs to adapt to contemporary life? The goal is to avoid a pastiche that undermines the original structure or an alien-like addition. Desmond and Jeannine Barrow found the perfect balance by integrating natural and modern materials into their 300-year-old thatched cottage.

Living History Having called this thatched cottage their home for over three decades, the Barrow family sees it as more than just a structure. “It’s a repository of our family’s memories,” says Jeannine Barrow.

A Delicate Blend of Past and Present

When the time came for an extension, the Barrows naturally turned to their architect daughter, Aisling. Her vision was a modern yet complementary addition to the cottage, merging oak, cedar, and glass – a distinct departure from the more traditional proposals they’d encountered.

Aisling’s design was influenced by both the simplicity of the original cottage and modern architectural feats like Gumuchdjian Architects’ Think Tank. The use of air-dried oak over green oak was a thoughtful choice to accommodate the extensive glazing, ensuring less movement in the structure.

Inside, the extension’s aesthetics seamlessly transition from structural to decorative, with engineered wood flooring and oak-finished doors harmonizing with the cottage’s historic charm.

Linking the Old and New

One of the project’s challenges was creating a connection between the cottage and the new extension. Aisling’s solution: two glass links forming a courtyard, cleverly avoiding issues like cold bridging. This new space, warmed by underfloor heating, also features a custom-made sculpture, enhancing the blend of tradition and modernity.

Invisible Boundaries

The design includes a minimalist laundry room, strategically placed to preserve the picturesque views of the surrounding landscape. “Our sunroom, bright and spacious, feels like a continuation of our garden,” says Jeannine, illustrating the successful integration of the extension with the natural surroundings.

Conserving the Original Cottage

The project also involved refurbishing the Grade II listed cottage. Aisling worked with a conservation architect to ensure the restoration was sympathetic to the building’s historical significance. The cottage’s reconfiguration included energy-efficient updates and a more functional bathroom layout, balancing the need for modern amenities with the preservation of its character.

A Family-Centric Project

Aisling, deeply connected to the cottage from her upbringing, faced the unique challenge of balancing professional objectivity with personal attachment. The construction process, involving multiple contractors and architects, took over a year but resulted in a harmonious blend of old and new.

Seeing From Within

To complement the interior, a landscape architect was brought in to design a garden that could be appreciated from the sunroom. The result was a patio area surrounded by a pond and wildflower meadow, enhancing the home’s connection to its natural surroundings.

Innovative Details

The sunroom, designed with thoughtful lighting and furniture choices, has become the family’s favorite space. Unique features like chain drains for rainwater add an element of interest to the functional aspects of the design.

A Homage to Heritage and Modernity

The Barrows’ project exemplifies how a historic home can be thoughtfully adapted for modern living. Their dedication to preserving the past while embracing the present ensures this cherished family home will continue to thrive for generations.”
