Why people pick a double carport

  • Both cars get outTwo proper bays means neither car is a three-point turn around the other, which is the whole reason people go double.
  • The beam carries the widthA wider opening is answered with a deeper beam rather than a post in the middle, so you are not parking around steel.
  • One structure, not twoA double shares one roof, one beam line and one set of footings, so it is less steel and less digging than two singles side by side.

Double carport questions

01How wide does a double carport need to be?

Wide enough to open both car doors without hitting anything, which in practice is 5.4m to 6.6m for two vehicles. Measure the driveway at its narrowest point and send that number; the kit is cut to it.

02Does a double carport need a post in the middle?

Not across the opening. The beam is sized to carry the full width, and the extra posts on a double sit along its length rather than between the two bays, so you are not reversing around steel.

03Can I park a boat under a double instead of a second car?

That is a common use for the second bay. Measure the trailer at its longest and the boat at its tallest, including anything on a canopy, and send both with your driveway width.

04Is a double cheaper than two single carports?

It uses less material for the same cover, because a double is one roof, one beam line and one set of footings rather than two of each. Send your measurements and we will price the kit either way.
