Bismarck Pergola Construction
Project: Pergola Construction Over an Existing Deck
Breaking up the sun over a summer living space
This homeowner wanted to enjoy her deck more often by adding shade with a custom-built pergola.
Because the deck was already in place, the first challenge was figuring out where and how to anchor the support posts. Luckily, the original builders had poured a concrete pad at least 6 inches thick that ran the width of the deck a few feet out from the house. That gave me a solid base for the two posts closest to the house. I accessed the pad through removable deck panels near the dryer vent and an outdoor faucet.
For the two posts on the far edge of the deck, I poured new concrete footings in the yard to ensure the pergola was anchored securely.
The structure is built from cedar-tone pressure-treated lumber sourced from Menards. This material has the strength of treated wood but a warmer, more natural look than standard green-treated lumber. The finished pergola measures roughly 12 by 12 feet—plenty of room to define an inviting outdoor living space.
Each summer, the homeowner plans to attach fabric shades beneath the pergola grid for added sun protection, making the deck comfortable even on the hottest afternoons.
