Showy Pergola with a 4ft Cantilevered Roof

This bright white pergola has a 4′ cantilevered roof that reaches back toward the house for full coverage of the patio. Western Timber Frame™ built it as an 8,000 Series pergola kit with a full arched knee brace and keystone on the front, Crescent Step beam and rafter ends, and a TimberVolt® Inferno® power post.

A cantilevered pergola roof covers space that would otherwise be too tight for another post. It also adds visual interest and more protection right where it is needed, next to the house.

Key Takeaways

  • Cantilever: the roof extends 4′ back toward the house without another post
  • Size: 22′ × 15′ 8″ roof in the 8,000 Series
  • Details: a full arched front knee brace with a keystone and six Classic braces
  • Power: a TimberVolt® Inferno® post for outlets, USB charging, lights, and a fan

What Does the Cantilevered Roof Add?

The roof measures 22′ × 15′ 8″ overall, and the side with the cantilevered extension measures 19′ 8″. By extending the roof back toward the house instead of adding a post, the pergola covers the whole patio while keeping the doors and walkway clear.

What Does the TimberVolt® Inferno® Power Post Include?

The TimberVolt® Inferno® power post runs wiring inside the timber, so power is right where it is needed:

  • A recessed plug with a weather-resistant cover
  • A GFCI outlet for protection, with a weather-resistant cover
  • An outlet just above the GFCI with two USB ports
  • A double switch halfway up the post, one for lights and one for a fan
  • An upper TV outlet with two USB ports
  • Separate connections at the top of the post for lights and a fan, both on the double switch

Beautiful job, and thank you for sharing!

Questions About Cantilevered Pergolas

What is a cantilevered pergola roof?

A cantilevered roof extends past the posts. On this pergola, the roof reaches 4′ back toward the house, covering space that would be too tight for another post.

Why choose a cantilevered roof?

It covers more of the patio without adding posts, keeps walkways and doors clear, adds protection close to the house, and gives the pergola a more interesting profile.

What does the TimberVolt® Inferno® power post include?

This post includes a recessed plug, a GFCI outlet, outlets with USB charging, a TV outlet, and a double switch for lights and a fan, each with a weather-resistant cover.

Can a pergola power a ceiling fan?

Yes. A standard TimberVolt® power post can handle a ceiling fan, with power routed up to the fan and lights at the roof.

Is shipping included?
