Costs deductible for capital gain on second home build

Hello, I built a second home starting in 2019, completed Nov 2021, and sold June 2023.  I've calculated capital gains, reducing for all the traditional costs of sale commissions, title and other closing costs, etc.  However what's unique about this case is the home was built in AZ over 2+year period, while my main home was in TX, therefore I was traveling back and forth over that period to have ongoing meets with the builder as the home construction progressed.  My question is would the travel costs (mileage, meals, hotels, etc.) associated with those builder meets be deductible against the sales proceeds?  Thanks.
