Keller, TX Shade Solution With Modern Appeal! Archadeck agreed that a modern-chic design was the best fit for their home and landscape. The finished project is built using cedar as the medium for the pergola addition. The clients chose dark walnut stain to increase the warmth of the already warm hues of the cedar. Archadeck attached the pergola addition to the house wall and installed matching gutters. The homeowner also had the area wired for electricity so they could easily add a ceiling fan and party lights overhead. To increase the protection and shade capabilities of the pergola, Archadeck also installed a Polygal polycarbonate cover in bronze.
