Bought a preconstruction home from Acorn and pretty satisfied with the purchase. The design centre to select upgrades has a lot more options than many competitors from my discussion with my friends and they also allow you to customize to a certain extent (at a cost of course).
During the PDI process, they communicated effectively and held themselves/their contractors accountable for issues we noted and they were quick to set up the appointments to have everything fixed. If the contractors did not do a good job or didn't arrive to complete their job, there was constant communication and they ensured everything would be done.
Marnie was the individual how is responsible for setting up all the appointments and she is FANTASTIC. She is always polite when we call and responds quickly when we email her.
I also want to note that the workmanship and quality of the final home is also at a much higher standard than many other builders.
We have had a positive experience with Acorn Home and would recommend other's to buy their houses from them.
