Box perimeter / Design details
Made for your setting.
Box Perimeter frames the outdoor room with a crisp architectural edge. A deep aluminium perimeter defines the silhouette while the roof fall and drainage sit within the frame. Fixed acrylic roofing preserves daylight without motors or moving roof parts.
Explore a project in detail
A first-floor deck required the perimeter, acrylic roof, façade relationship and drainage to read as one deliberate addition.

Works well when
- A contemporary, level perimeter suits the existing architecture.
- The roof fall and drainage can be concealed within the available depth.
- The pergola is prominent from the street, garden or main outlook.
We’ll resolve together
- The depth needed for structure, fall, gutter and access.
- Where downpipes and discharge can go.
- How the stronger horizontal edge sits beside the house.
Clean edge versus required depth
The perimeter has to hold structure and roof services. Its visual weight is tuned through proportion, colour and post placement.
Concealed drainage versus service access
Hidden fall and gutters still need inspectable, maintainable outlets and a clear discharge path.
Architectural definition versus subtlety
A box perimeter creates a stronger frame than a simple pitched roof. That can be useful or too dominant depending on the house.
Structure and roofing
A deep aluminium perimeter carries the fixed roof within the frame. Gutters, outlets, downpipes, posts and fixings are coordinated with the completed geometry and site conditions.
Bay sizes and member depths confirmed by the project-specific design
Foundations and fixings resolved from project-specific engineering where required
- Aluminium perimeter frame and posts sized for the completed design
- Acrylic roof set into the frame
- Gutter and downpipe details resolved for the completed design
- Powder-coated finish selected with current care requirements
Clear or softly tinted acrylic sheets
Concealed fixings where feasible
Downlights within the perimeter
Roller blinds considered for selected exposure and privacy priorities
Installation and maintenance
The project programme and on-site sequence are confirmed in the proposal after site and supplier checks
Cleaning and inspection follow the current written guidance for the selected frame finish, acrylic roof and drainage
Will the frame look heavy?
The visual weight depends on the final member depths, post positions, colour, roof depth and relationship to the home. Those proportions should be reviewed in the project design.
Can gutters hide in the frame?
They can be coordinated within the perimeter where the completed member sizes, roof fall, outlets, access and discharge path allow it.
