This step by step diy article is about attached pergola plans. Building a pergola attached to your house is a complex project, but you can get the job done by yourself, if you follow our plans free and use the right tips, techniques and materials. Generally speaking, pergolas are built to create a nice shaded area, where you could take your dinner or read a book, while enjoying the fresh air in your garden. If you don’t want to build a patio pergola in the middle of your garden, you can still have a cozy place with a nice design, if you attach it to your house, next to a simple deck.
An attached pergola requires a ledger anchored to your house, several outer posts (according to the size of your pergola) and wooden shading elements. As you can see, there is nothing complicated involved in the building process, provided you work with great care and make sure everything is well aligned and leveled. Don’t forget to study the building codes before planing the attached pergola, as there are certain aspects where you have to comply with the local regulations (the depth of the holes that support the posts, the type of materials used, etc.). Despite the construction techniques required in the building process, we will show you the main methods, to help you get the job done quickly and in a professional manner.
There are many designs you can choose from when building your attached pergola, but you have to remember that the more complex the shape, the greater the costs. Therefore, you should make a blueprint of the pergola before starting the actual project, in which we recommend you to wrote down the dimensions of the components and their costs. In this manner, it is easier to make a cost estimation and to keep the expenditures under control. If you afford and like the idea, you could even cover the attached pergola with polycarbonate sheets, to protect the deck or patio from rain and snow.

- cement, sand, gravel
- safety gloves, glasses
- circular saw
- hammer, spirit level, carpentry pencil

Attached pergola plans
Building an attached pergola is a straight forward job, if you evaluate the situation properly and select the building plans with good judgement. As you can see in the image, the construction involves the installation of several elements, therefore you have to plan everything from the very beginning.
Smart tip: An attached pergola will enhance the look of your house an add value to your property. Work with great care and align the components carefully, in order to avoid potential issues.
Pergola attached to the house plans
Decide the size, place and design of the pergola. While the building techniques are similar, a beam positioned differently, or the materials used have a significant impact on the look of your pergola. For example, placing the shading elements perpendicular to the house will create a different design as compared to placing them parallel.
Smart tip: The best way to use the pergola at its full potential, is to build it on a large deck or patio.
Use batter boards and string to lay out the pergola like a professional. Measure the diagonals and use the 3-4-5 rule to make sure the corners are right angled. This aspect is essential for the success of your project, therefore pay attention during this step.
Smart tip: Dig 3′ deep holes (6” below the frost line), add a 3” layer of compacted gravel and pour in concrete. Don’t forget to place the anchor in concrete, before it dries out.
The height of the posts should vary according to your needs and tastes, but in general it should be between 8-9′. In order to anchor the posts properly, we recommend you to plumb them by using a spirit level, brace them in two perpendicular directions and afterwards drive in the screws.
Smart tip: Don’t place the posts too far one from another (at most 12-14′), otherwise the support beams might curve on the long run.
Attaching the cross beams to the house can be done in several ways, including setting posts along the house, but the easiest way is to anchor a 2×8 ledger with several bolts. As you can see in the image, you need to install a vinyl flushing over the ledger to prevent the water from damaging the house timber frame.
Smart tip: The top of the 2×2 support should be at the same level with the top of the posts.
Building a pergola attached to a house
The next step is about securing the 2×8 or 2×10 support beams to the posts. The procedure is straight forward, if the wooden posts are plumb and perfectly aligned. In addition, we recommend you to use several C-clamps to lock the beams into position, before driving in the 7” bolts.
Smart tip: If you use screws and not nails, you have to pre-drill holes in the breams, to prevent wood from splitting.
In our attached pergola plans you can also see how to cut the ends of the beams, as to obtain a nice design. Nevertheless, you have to remember that you can adjust the size of the cut ends, according to the materials you use, to fit your needs and tastes perfectly.
Smart tip: After you have cut the decorative ends of the beams with a a jigsaw, we recommend you to smooth their edges with a sanding block.
Installing the 2×6 shade elements perpendicularly on the support beams can be done in several ways. First, you can notch the shade elements and fit them between the support beams, or place them over the beams without cutting them out.
Irrespective of the case, use a tape measure to make the cuts accurately. Lock the cross-beams into place, by toenailing them with appropriate screws, after drilling pilot holes.
Placing the shade elements is not difficult, especially if you ask a friend to assist you and hold them into position while you drive in the screws. Work with great care, making sure you use a spirit level to plumb them.
Smart tip: The distance between the shading elements will have a direct impact on the sunlight that gets trough the roof, therefore adjust it to your needs. Usually, we place the crossbeams every 1-2′, but you should fit them according to your own needs.
If you want to add personality to your attached pergola, we recommend you to follow our plans and cut the ends of the shade elements in an unique manner. As we have already mentioned, we use usually 2×6 beams to build these elements, but you can get the job done also with 2x4s.
Use a jigsaw to cut their ends and place them on the support beams. Next, connect them to the ledger by using joist hangers or corner brackets.
After you have set the crossbeams into place, you could make the whole structure more rigid by installing several 2×4 or 2×6 slats, perpendicularly on the crossbeams. As you can see in the plans, the best way to lock them into place is by cutting notches at their joints with the shade elements.
Smart tip: Place the slats every 3′ or so, making sure they are equally spaced.
After you have installed all the parts into place in a professional manner, you have to fill the holes and other gaps with wood putty, let it dry for several days and then sand the surface with medium grit.
Smart tip: If you want to enjoy the comfort of your attached pergola even during the rainy days, you could cover it with poly-carbonate sheets. Nevertheless, it is essential to drain the water, therefore the roof should have a little slope.
After you have built the main structure, you should customize the attached pergola, according to your needs and tastes. Therefore, you could, for example, install x-shaped railings and balusters, in order to enhance the look of your house.
Smart tip: On the other hand, you could also install a rustic wooden bench and a simple planter to add character to the wooden pergola.
