Smallest House in Great Britain Castle

Address: Conwy Quay, Conwy, Wales

The Smallest House in Great Britain is a tiny red-painted house on the quay in the walled town of Conwy in north Wales, often cited as the narrowest house on the British mainland. It is a popular photographic curiosity on Quay Street beside Conwy harbour.

The house has a single narrow frontage facing the quay and historically served as a fisherman’s dwelling; its compact proportions are the principal point of interest for visitors. The exterior and the narrow internal plan are the main draw rather than extensive interior displays.

The house forms part of the historic harbour frontage within Conwy’s medieval town walls and sits close to other visitor attractions in the town such as the castle and quay.

Located on Quay Street in Conwy, the house fronts the harbour and is reached on foot from Conwy town centre.

• Width: Measures approximately 72 inches (about 1.83 metres) across at its narrowest point, which is the feature that gives it its claim as the smallest house.

Conwy is on the North Wales coastline. From Llandudno Junction railway station take the local train or a 20-30 minute local bus to Conwy; the smallest house is a two‑minute walk from Conwy Castle and the quayside car parks.

• Visit early morning to see the little house without tour groups clustered around the viewing window.
• Stand on the quay and photograph the narrow façade reflected in wet cobbles after rain - the optical trick makes the house look absurdly tiny.
• The interior is viewable only through a window; don't expect a full museum experience but do stop by the adjacent Conwy tourist office for context.
