The process was very fast and efficient, with the drawings being done quite quickly and professionally. The permit process once we submitted the request to the city only took two weeks! I was also told it would be at least 6 weeks wait, so this was a great surprise and I have to thank Sikandar and team for getting it done. Thank you so much for taking what is usually a stressful process and making it great!

 Trustindex verifies that the original source of the review is Google. If you are looking for a great architect, I highly recommend Mr. Sikandar and his wonderful Team at Green Target Engineering.

He recently helped me with a commercial project and had earlier helped me with residential and commercial services on multiple occassions. Not only did he provide fantastic, precise drawings, but he also took care of arranging all the necessary permits, which made the process completely stress-free for me.

What I appreciated the most was his availability. He picks up his phone every single time I call, which gave me so much peace of mind throughout the project. Great service, great communication, and great results!"

 Trustindex verifies that the original source of the review is Google. I have worked with Green Target on a couple of my basement projects and I am extremely satisfied. I have worked closely with Sikander & Najeeb for these projects. They are very punctual, detail oriented and provide the required guidance and do not take short cuts in getting the job done. Their drawings are first time right and rarely require any rework or deficiencies are raised by the City. NAJEEB has extreme attention to detail and clarity of thought and provides creative solutions while creating the floor plans. 100% satisfaction guaranteed and will vouch for their services

 Trustindex verifies that the original source of the review is Google. If you need building permit drawings (architectual, mechanical etc... in Ontario look no further!!

I can't say enough about my positive experience with Sikandar and Green Target Engineering. Not only did he do all the drawings for our bakery relocation, but he went over and above during the entire process. They are very reliable, and knew how to handle every situation that arose with the city planner.

All timelines were met as promised, and their customer service is 10/10.

I won't hesitate to use them again. Thank you!
