The pergola is one of the many solutions that allows as much protection from the sun or the rain (if it is covered) than to bring an aesthetic touch to the garden. Freestanding (our example) or leaning against a gable or a facade, it is ideally used as a support for climbing plants. Set back from the house, this autoclave pine model offers panoramic views of the surrounding countryside.

Painted or stained wood

The structure consists of four 90 x 90 mm poles joined by 28 x 145 mm beams. All elements are Class 4 planed pine (fully adapted for outdoor use) that can be painted or stained. In its configuration, the pergola has a perforated roof that acts as a sunshade. However, it can be equipped with various sun protection accessories and even railings.

Declaration or not?

Side work, mount or create a pergola is not comparable to the installation of a parasol!
It is mandatory to comply with the urban planning code. Even if up to 20 m2, free to everyone to realize a pergola without manifesting near the town hall. It is imperative to make a preliminary declaration of works for works whose surface is between 20 and 40 m2.
Beyond that, you have to file a building permit. In any case, it is better to consult the land use plan (POS) or the local urban plan (PLU). If your home is in a subdivision, check its rules too. Here, the 5 m pergola2 does not require any procedure.

Check the ground level. If there is too much difference in height, install wooden blocks or concrete blocks of 90 x 90 mm section.

Measure and trace the location of the four posts. Their center distance is here 234.60 cm. Use a square and a mason's ruler to ensure proper alignment.

Fit a pergola kit: drill

Measure and trace the footprint of the future chalk line pergola. The four sides meet at the center of each post.

Check the squareness of the plot by measuring the diagonals, which should be equal. If not, repeat the measurements.

2 Assembly of the sunshades

2 Assembly of the sunshades

To mount the structure forming the roof, work on the ground. Place four intermediate crosspieces (28 x 145 mm) on their edge, spaced 50 cm apart. Fit the other four sleepers into the notches provided for this purpose for a half-timber joint.

Fit a pergola kit: drill

At each junction, drill a Ø 6 mm pilot hole using a drill with a minimum of 120 mm wood drill bit. Then screw (here 16 screws Ø 6 x 120 mm).

Fit the four peripheral crosspieces and screw them to the ends of the intermediate crossmembers with Ø 4 x 50 mm screws.

3 Installation of poles

3 Installation of poles

Position the fixing plates of the posts in each corner, trace your marks in pencil, drill and peg.

Fit a pergola kit: pergola

Locate the mounting holes of the plates. They fit into a machined groove in the foot of each post. Pre-drill the post, insert it on its turntable and screw.

Fit a pergola kit: drill

You can put the roof directly on the posts or, as here, screw the outer cross members on the posts to hold them in place (useful in case of wind) before fitting the structure.

Fit a pergola kit: each

Position and hold the finishing profiles using clamps, then screw them to the right of each post and cross (2 x 2 Ø 3.5 x 40 mm screws).

Wind resistance and protection

Many DIY manufacturers and retailers offer canvases that have easy-to-install fastening systems (Velcro, eyelet / tourniquet, etc.). If you want to protect yourself from the rain rather than the sun, clear polycarbonate sheets provide perfect pergola cover.
But beware, if your pergola is lined with a cover that may catch the wind (canisse, canvas, plates...), it must be firmly secured to the ground (as here). Another solution is to pour concrete pads at the location of future poles, by sealing suitable metal shoes.
