12 × 14 Pergola Before and After: Shade for a Hillside Yard

A 12×14 pergola (12 feet by 14 feet) is a mid-size freestanding structure, large enough to shade a seating group or a dining table. This before and after shows one going into the corner of a hillside yard, where stepped retaining walls left a lawn in full sun.

The structure is a Western Timber Frame™ 12′ × 14′ Full Size pergola, standing on its own posts beside the retaining walls.

Key Takeaways

  • A freestanding pergola can add shade to a spot where planting a shade tree is not practical.
  • This 12′ × 14′ pergola sits in a lawn corner framed by stepped retaining walls.
  • The timbers are cut before the structure ships, so the work on site is assembly.
  • A time-lapse video below shows how a pergola goes together.

Before and After

Before, this corner was open grass against tall retaining walls, with nothing to give shade. After, the same corner has a roof of rafters and shade planks and a defined place to sit.

Nothing else in the yard changed. The walls, the stairs, and the lawn are the same. The pergola gives the space a purpose.

When Is a Pergola a Better Choice Than a Shade Tree?

A pergola can provide shade in places where a tree would be a problem. Trees are often kept away from buildings, overhead lines, septic systems, pipes, gas lines, and drainage areas, because roots and branches can interfere with them.

A pergola has no roots, gives shade as soon as it is up, and stays the same size. Its open roof filters the sun, and the amount of shade changes with the direction it faces, the time of day, and the time of year.

How Fast Does a Pergola Go Up?

Assembly time depends on the structure’s size and design, the site, and the crew. Because Western Timber Frame cuts the joinery before the structure ships, the work on site is assembly rather than measuring and cutting. Many pergolas this size go up in an afternoon to a day once the footings are ready.

Questions About a 12×14 Pergola

What fits under a 12×14 pergola?

A 12′ × 14′ pergola is large enough for a seating group or a dining table with chairs. The posts stand inside the roof line, so the footprint between posts is smaller than the roof. See the pergola sizing guide for more.

Can a pergola be installed on a sloped yard?

Yes, when the posts stand on level footings. On this project the pergola sits on a level lawn corner created by retaining walls.

Who installs the pergola?

Homeowners, local contractors, or independent installers can assemble it, depending on location. The timbers arrive pre-cut and ready for assembly.

What warranty comes with a Western Timber Frame pergola?

Every Western Timber Frame structure carries a limited structural warranty. Length runs from 3 years on Deck Structures to 20 years on the 12K Series, based on the series you purchase.
