In 2008 we bought a property with plans to build our dream home. We were referred to Darrel Weishar at DAR-CAD Designs by our builder. Although we had some ideas of what we wanted, Darrel was very helpful incorporating those ideas into a house design that suited our desires, tastes, and the lot itself. We met with Darrel many times to prefect our house plans. Darrel was very accommodating when scheduling these meetings. He made us feel like our house was the only house he was designing! Thank you Darrel for your professionalism and expertise. We are very excited to move into our custom designed home in just a few months!

DAR-CAD Designs was recommended to us by a local homebuilder and several neighbours. We were extremely pleased with the value and service provided by Darrel Weishar both when he designed the 5600 square foot home for our property, and the 2000 square foot cottage design we ultimately decided on. We were so impressed to learn that Darrel continues to monitor the construction long after his designs are complete. The value received from DAR-CAD is unbelievable!

Darrel helped us design our new home. We had seen a beautiful house in Holland and that was the house we wanted to build in Canada. We were very happy with Darrel's work. Everything was done professionally and in a timely manner. In 2009, we asked Darrel to help us design a new shed to go with the house. We are very happy with that as well. We would definitely ask Darrel for any other future projects.

When planning to renovate our century old stone homestead, it was recommended we contact DAR-CAD for our plans. From our initial meeting and onward, we had no doubt that working with DAR-CAD was a great investment. We had definite ideas/dreams for our home and we were thrilled when Darrel Weishar was able to capture our vision with the very first set of draft prints he presented to us. Of course some tweaking need to be done, but in the end Darrel designed the addition to expand space and re-designed the existing interior to provide improved functionality, while working within the confines of the exterior stone walls. We have had many compliments because the addition enhances the existing interior and increases the aesthetic curb appeal of the historic farmhouse. It is also important to note that while interviewing general contractors for the project, when it was mentioned that DAR-CAD worked on our design, every contractor we met with had the utmost confidence in Darrel Weishar's ability and experience.
