We recently completed a custom build with Crimson Cove Homes and have been very pleased with the finished product. From when we had an unconditional purchase agreement to when we took possession was approximately 50 weeks.
Both my wife and I are very detail-oriented, so when some things were not completed according to expectations, they were quickly noted and brought to the attention of the Crimson Cove team who had the issues rectified very quickly.
Part of the challenge with any new build is that the trades are all working for multiple stakeholders -- perhaps multiple builders, and almost certainly multiple jobs, each of them wanting to have the job done on-time. This did result in some re-work as they did things "the normal way" despite our plans specifying something different. With that in mind, there is only one Crimson Cove trade partner that I would completely avoid in the future (the structured cabling was sub-standard) -- of the dozens of folks involved, that is a pretty good sign.
The sales team was very good at ensuring our concerns were heard by the necessary folks, and our site superintendent was also very good at wrangling the trades as needed.
While the process was far from a "set-and-forget" one (at least to meet our detail-oriented standards), I would strongly recommend Crimson Cove Homes to anyone seeking a new home, particularly a custom-built one.
