A box-perimeter pergola presents a level architectural outer edge while the working roof fall and drainage are contained within the frame. It creates a crisp horizontal profile, particularly where the addition is prominent from the street, garden or main outlook. It is not a flat roof.

The perimeter must contain the structure, fixed acrylic roofing, gutter, outlets and appropriate service access. Member depth, post position, colour and the selected acrylic sheet determine how the frame relates visually to the home and how the space responds to daylight.

At the Mt Maunganui project, the perimeter, acrylic roof, façade relationship and drainage were designed to read as one deliberate addition over a first-floor deck.

To assess whether a box-perimeter form could suit your project, share the suburb, photographs and approximate dimensions.

About the
Seller

Sanctuary Pergolas designs, builds and installs bespoke fixed-roof pergolas for Auckland homes and selected commercial projects.

Rather than starting with a standard kit, we start with the site. The architecture, intended use, structure, roof, daylight, drainage and integrated details are resolved together so the finished pergola belongs to its setting.

We take residential projects from the first brief through design, build, installation and handover. We also work with architects, designers and builders, from early concepts to clearly defined packages within wider project teams.

Our completed work spans residential outdoor rooms, hospitality terraces, recreation venues and workplace canopies. Share your suburb, photos, approximate dimensions and intended use to begin a project conversation.
