We have owned 2 Westview homes and we have been very happy with them. The first was a spec home that we had little input into but we loved everything about it except the lot so we decided to build the same house on a different lot.
During the build, we did many visits to check the process of the build and the items we had issues with were dealt with fairly quickly. The salespeople were great and incredibly helpful. The site supervisor was always willing to listen to our suggestions and to try and accommodate the changes that we wanted. When we moved in, there were only a few small "nitpicky" items that were dealt with or scheduled to be fixed at a later date.
With the first house that we had with them, there were some warranty issues that had to be fixed very quickly and they responded to that demand without any issue at all. Some of the less urgent warranty issues, took a long time to be rectified and we had problems with trades people not showing up when they were supposed to which was an inconvenience but again, these were small issues.
If you do build with Westview, I recommend doing many walkthroughs throughout the building process to ensure that things are being completed exactly how you want them. The only negative that I have about this new house was that during the possession day walkthrough, our "nitpicky" items seemed to be regarded as insignificant. Even though they weren't major items, they still mattered to us after spending a considerable amount of money to have our new house built. It is a huge investment for us and we want our home to be as perfect as possible.
We would definitely build with Westview again, although we are hoping to stay in this house for a long time!
