A carport keeps the car out of hail, falling leaves and summer sun, and gives a dry walk from the driveway to the door through Box Hill's long wet winters. Rain at Scoresby, the nearest long-record Bureau of Meteorology station, averages about 850 mm a year over roughly 115 wet days. Peak Pergolas designs and builds single, double and gable carports across Box Hill, Box Hill South, Burwood, Nunawading, Mitcham and the rest of Whitehorse, with galvanised steel frames and Colorbond roofs. Each carport is drawn to the driveway and the house, checked against the boundary and setback rules and lodged for the building permit every carport in Victoria needs.

Peak Pergolas Box Hill
Carports in Box Hill come in a few standard sizes and roof shapes. The right one depends on how many cars need cover, how wide the driveway is and what the house roof looks like.
A single carport covers one car, usually on a side driveway running past the house. On the narrow side drives of older Box Hill and Mont Albert homes, the posts are set on the fence side so car doors open freely on the house side, and the roof is kept high enough for a four-wheel drive or a roof rack.
A double carport covers two cars side by side, typically across the front of a wider block or in front of an existing garage. Heavier beams span the full width so there are no posts between the cars, and the roof can be extended to cover a boat, trailer or caravan.
A gable carport rises to a ridge and suits homes with a pitched tiled roof, which covers most interwar and post-war houses in Whitehorse. Built to the same pitch, it looks part of the original house from the street instead of a later add-on.
A flat carport, set at a low fall to drain, is the most economical shape and suits a modern facade or a site where height is limited. A skillion carport has a steeper single slope and gives a clean modern line on newer homes in Vermont South and Burwood East. See skillion roof pergolas.

A carport can be fixed to the house or stand completely on its own. The choice depends on where the driveway runs, how high the eave is and whether the carport needs to link to other covered areas.
An attached carport is fixed to the fascia or wall of the house along one edge and stands on posts on the other. It uses fewer posts, keeps the driveway clear and gives covered access straight to a side or front door. Where the eave is low, the carport roof can sit on fly-over brackets above the gutter to gain height.
A free standing carport has posts on every side and no fixing to the house. It suits a driveway that runs away from the house, a carport at the back of a long block or a home where the fascia cannot carry extra load. Because nothing ties it to the house, it is braced and footed to stand on its own in wind.
On many Whitehorse blocks the driveway runs beside the house straight into the back yard. A carport over the drive can continue into a patio over the back slab, giving one continuous roof from the car to the outdoor table and a dry path to the back door. The two parts are drawn and permitted together.

Most carports in Box Hill sit close to a side or rear boundary, so the boundary rules in Victoria's Building Regulations 2018 shape the design from the start.
Regulation 80 applies to a carport built on or within 1 metre of a side or rear boundary and left open on the boundary side. Its average height must not exceed 3.2 metres and its maximum height 3.6 metres, unless it is matching an existing wall or carport on the adjoining boundary. The length along the boundary is limited to the greater of an existing abutting wall or carport, or 10 metres plus 25 per cent of the remaining boundary length. The roof pitch and post heights are drawn to stay inside those limits.
A carport in front of the house is checked against the front setback rules before it is drawn, and Whitehorse City Council's rules require a building permit for any structure further forward than the front wall of the house. Properties with a heritage or neighbourhood character overlay can also need a planning permit, which is checked on Whitehorse Maps at the start.
Every carport in Victoria needs a building permit. Drawings, footing and beam engineering and the application are prepared and lodged as part of the job, and the carport is inspected before sign-off. See pergola permits for how the process works.

A carport is exposed on most sides and carries a large roof area, so it needs the same care with materials, water and footings as any part of the house.
Galvanised steel posts and beams span the width of a double driveway without middle posts and never need oiling or painting against rot. The roof is Colorbond steel sheet in a colour matched to the gutters and trim. Steel frames can be powder-coated or finished in a Colorbond colour, and timber can be used where the carport needs to match an older home.
A carport roof can be as big as a small house roof, and with about 850 mm of rain a year in this area it sheds a lot of water. The gutter on the low side is sized for the roof area and the downpipe is connected to the stormwater system, so water does not run across the driveway, pool by the front door or flow onto a neighbour's land.
Posts beside a driveway sit on concrete footings sized to a soil test under AS 2870. Where they land in an existing concrete drive, the slab is cut and a footing poured beneath it. Footings are kept clear of the electricity box, gas lines, drains and the roots of street or garden trees, which are located before any digging starts.

Every carport is priced from a free measure and a written, itemised quote, so the total can be checked line by line before work starts.
A single flat carport is the most economical. A double carport costs more for the larger roof and heavier beams, and a gable roof costs more again for the ridge, extra framing and gable infill. Free standing carports need more posts and footings than attached ones, and fly-over brackets are their own line.
Many Box Hill driveways already have an old timber or steel carport, or a tired garage at the end of the drive. Removing and disposing of an old structure, cutting the concrete driveway for footings and repairing a fascia are listed separately in the quote. Where the carport runs up to an old garage that is now used for storage, a broken tilt or roller garage door can be removed and the opening framed or closed off so the carport and garage work as one space; that work is also its own line.
Carport kits come in set sizes and suit a simple, level, rectangular site. A site-built carport is measured for the actual driveway, so the posts land where they are wanted, the height stays inside the boundary limits, the roof matches the house and the gutter ties into the stormwater. On a narrow side drive or a sloping block, that fit makes the difference between a carport that works and one that blocks the car doors.


A visit to measure the house and the yard, talk through materials, roofs and colours, and then a written, itemised quote.

Drawings and engineering are prepared for the site, overlays are checked and the building permit is lodged.

Footings, frame and roof are built and inspected at each stage, the site is cleaned up and the finished structure is handed over.
The cost depends on the size, the roof shape, whether it is attached or free standing, and the site. A single flat carport is the most economical, while double and gable carports cost more. Removing an old structure and cutting a concrete drive for footings add to the price. A free measure gives a written, itemised quote.
Yes. Every carport in Victoria needs a building permit, and carports near a boundary must meet the height and length limits in the Building Regulations. Some properties also need a planning permit because of an overlay. The drawings, engineering and application are prepared as part of the job.
Under Victoria's Building Regulations, a carport on or within 1 metre of a side or rear boundary can have an average height of up to 3.2 metres and a maximum height of 3.6 metres, unless it matches an existing wall or carport next door.
Yes. A carport over a side driveway can continue into a patio over the back slab under one roof, giving a dry walk from the car to the back door. Both parts are drawn and permitted together.
Galvanised steel spans further with fewer posts and needs no oiling, which suits most driveways. Timber suits an older home where the carport should match the house. Both can carry a Colorbond roof.
The driveway, the house fascia, the distance to the boundary and the fall of the ground are measured, and services in the drive are located. Sizes, roof shapes and colours are talked through, and a written, itemised quote follows.
