Built to Fit, Designed to Last
The Sierra was developed in response to a common challenge: how to receive parcels securely when your gate or garden wall doesn’t allow for a freestanding or gate-mounted box. Our solution was a sleek, compact parcel and letterbox built directly into the wall — with thoughtful rear access that means no more stepping outside.
Its rugged construction is no accident. Like all products from this supplier, Sierra is forged in Europe by a family-run company with roots in blacksmithing and a deep understanding of outdoor metalwork. Their region sees harsher winters than the UK, so every product they create is built with the kind of resilience we know matters.
Ideal for classic brick gate posts, rendered boundary walls, or custom-built piers, Sierra is subtle, secure, and supremely useful — a house parcel box that looks like it’s always been part of your home.
