The Challenge: Bringing Contemporary Family Life to a Historic Cottage

The Dower House is a listed building of genuine character, its origins dating to the 17th century. Its thick walls, low ceilings and small windows give it the warmth and intimacy that makes old buildings so beloved, but those same qualities presented a real challenge for a family wanting to live in it fully in the 21st century. The rooms felt enclosed and dark. The garden, the wildlife and beautiful countryside surrounding the house was barely visible from within it.
Working with a listed building requires a particular kind of care and skill. Every intervention must be justified to the satisfaction of the local planning authority and the relevant heritage bodies, and the design must demonstrate a genuine respect for the significance of the original structure. This is not a constraint that diminishes the architecture, it is one that demands a more considered and thoughtful response than an unconstrained project might.
The clients wanted space that worked for contemporary family life: generous, light, connected to the garden and the landscape, and calm enough to be a genuine refuge. The challenge was to deliver all of that whilst honouring the history and character of the building they had chosen to call home.

The Design: Open to the Countryside, Rooted in the Character of the Original

Simon Mack Architecture's approach was to place the new extension in clear, honest dialogue with the old, contemporary in its materials and its detailing, but composed with a sensitivity to the scale and texture of the historic cottage alongside it.
The extension is timber-clad, its warm boards providing a material connection to the rural setting and oak porch and a subtle contrast to the lime-rendered walls of the original building. These will gently weather. The new extension opens fully towards the landscape: the garden-facing elevations are almost entirely glazed, with views across the garden and out to the countryside beyond. The glazing is carefully considered so that the extension does not feel exposed or overlooked, but rather sheltered and private, a room that looks out with confidence whilst remaining a comfortable place to be in.
One elevation of the extension is open-sided, allowing the countryside views and the movement of air and light to enter the space freely, blurring the boundary between the interior and the garden in a way that a fully enclosed room never could. A living wall, planted for year-round interest and colour, and changing beautifully with the seasons, brings the garden to the house in a more immediate and tactile way, and creates a verdant backdrop that softens the contemporary materials around it.
Tucked into the living wall is a reading nook: a window seat built into the architecture, sized and positioned to become exactly the kind of favourite corner that a home should have, somewhere to sit quietly, to look out, to read, to watch the light change across the garden. The existing entrance to the house was enhanced with a traditional oak porch, which adds both a practical covered threshold and an architectural element that speaks directly to the age and character of the original building, anchoring the new extension firmly within the historic context.

The Outcome: A Calm, Beautiful Retreat Where Nature Is Always Present

The Dower House is now a home that works on every level. The historic cottage retains every ounce of its original character; its thick walls, its intimate rooms, its sense of having stood in this landscape for centuries. But alongside it, the new extension offers something the old building never could: space that is open, light-filled and deeply connected to the countryside it sits within.
The family watch pheasants and deer moving through the garden from the comfort of the glazed extension, the wildlife that was previously glimpsed through small windows is now a constant and unhurried presence. The reading nook has become exactly what a reading nook should be: a loved and well-used refuge, the place where children settle with books and where adults find a few quiet minutes at the end of the day.
This is a project about the balance between old and new, between the enclosure and warmth of a historic building and the openness and light that a well-designed contemporary extension can bring. At the Dower House, both exist together in easy and natural harmony.
