Looking for a traditional pergola that will hold up fine in any weather for 20 years plus? Want to be sure it is truly environmentally friendly? We have over 25 years experience making the Design to Install process simple. Let us know what you need in rough terms. One of our experienced designers will email you drawings back and forth until you say “perfect, build it!”.
Specifications have the following sections, any of which you may go to directly by clicking on it:
DIMENSIONS & DRAWINGS (PROVIDED PRIOR TO CONSTRUCTION)
When we receive any Pergola order, we will provide you with a detailed set of drawings based on the options and sizes chosen. The drawings will clearly show each detail and dimension from 3 different angles. They are an excellent tool for you to double check each detail, making sure everything is exactly as you'd like before we begin to build. Initial drawings are emailed within 5 business days, and we'll revise your drawings as needed to make sure all details and sizing issues are perfected prior to beginning construction.
Below are some examples of drawings sent to prior customers:
Corner posts are 5 1/2" by 5 1/2" (standard sized 6x6) and are recessed 12" in from roof dimensions (This can be adjusted to meet your needs, just let us know).
Roof support timbers (lintels) and rafters are 1 7/8" x 5 3/4". If you prefer a different sizing or style write what you would like in the comments section or contact us.
Posts normally ship 9' long. 9 posts make the top of the roof 9' also and give you an 8' 4" clearance ("ceiling height") under the rafters. About 90% of our pergola customers go with the default 9' post height. If you'd like your pergola taller or shorter, just select Other Height and write in what you would like in the comments section.
The maximum roof size is 20' in either direction with a 4 post structure. The maximum span (with the standard timber sizes mentioned above) is 18' 2 1/2" on center between posts. Structures over 20' in any direction are built with an additional post to support roofs between 20 and 40 feet. For example, a 30' x 20' free standing pergola has 6 posts.
Forever Redwood Pergola kits are completely assembled in the shop prior to shipping to be certain everything fits together perfectly. All timbers are notched into one another to increase structural strength and to lock all of the pergolas timbers in place so they will never sag, twist or move. There are hundreds of notches in the larger pergolas. Full notching is rarely practiced because it is labor intensive, but it is one of the secrets to a long lasting and beautiful pergola.
All assembly hardware is included and is stainless steel.

For additional long-term structural strength, we add solid timber blocking in-between the dual support timbers as shown in the drawing below. With this blocking, the dual supports are in effect converted into one solid 5 3/4" x 61/2: or 7 1/4" x 6 1/2" timber as shown below:

All You Need is a Few Tools and a Friend.
Assembly is best done by two people over a half to full day depending on size. Pergolas require a ratchet, wrench, hammer and ladder. Some assemblies may require a drill to attach the posts into concrete. As with all of our products, we preassemble pergolas in our shop to ensure everything fits together. All hardware is included with clearly labeled parts. We also include detailed step-by-step instructions.
Take a look below at our assembly instructions for specific details. If you'd like a concrete pour to hold the posts, your project will require an additional half day prior to assembly. Please complete the concrete pour a few days prior to assembly to allow the concrete to cure.
Special skills are not required to re-assemble our pergolas. If you would like help, just let us know. We have our own team for installations in California, Nevada and Southern Arizona, and a network of local contractors we recommend for farther afield.
Care: Your Forever Redwood Furniture will last for decades in year-round weather without maintenance.
Depending on the wood grade you choose, you should expect your furniture to last 10-40 years without maintenance even in climates with harsh, year round conditions.
Being outside year-round is rough on all wood finishings. The surface absorbs UV rays and pollution, there is a constant variation in moisture and temperature, and oxidization occurs. Over the years, most woods degrade and decay, and the surface color will slowly fade towards a silver patina. This is not the case with Forever Redwood. The silver patina is surface deep (less than 1/64") and is not indicative of decay. Your set will last decades and will not compromised in any way by surface color changes. We keep our display items as is without refinishing as examples to show off the natural aging process (we like the patina!).
Although Forever Redwood is maintenance-free, we recommended that you take a few minutes as needed to clean by either hosing down and/or brushing/dusting away accumulated debris (no soap or chemicals needed). If you’d like to keep your set looking its best for decades, please go to: Care and Finish.
