We looked at sheds from the box stores and we looked at sheds from Costco and all of them required that we build the shed. In addition, we would have to pay extra for the roofing materials, and in some cases for the flooring too. NW Sheds built the shed, including the ramp (an extra $30) for a total of $1,500. The Costco shed would have cost $1,100 plus tax. Add the cost of the roofing material and we figure that NW Sheds built a very similar shed, if not a higher quality shed, for a mere $200. All I had to do was paint the shed. The building was polite, prompt, and cleaned up after himself. There was a $50 delivery charge because we are in Olympia and the truck comes from Sumner, but we felt that was quite reasonable considering the price of gas these days. Best of all, the builder built the shed in less than 3 hours. We are very pleased with our new shed! If we ever need another shed we'll be purchasing it from NW Sheds.
