It's been almost a year since I wrote my first review for King Street Construction. When I wrote that review, my tenant had just moved into the first ADU Kevin and the team had built for me. Since then, they've completed the second and third ADUs. I moved into the second one in September and the third one will be occupied tomorrow. The first two ADUs were the one-bedroom model and the third one is the two-bedroom model. All three ADUs are in Guelph. No matter what random changes the city added
