The main bedroom is vast. The Dressing Room could easily be extended as far as the main bed door to make another bedroom.
The ‘entertainment room’ is even more vast and could be halved to provide another bedroom with en suite loo.
If I was to win this (unlikely as I have never even entered an Omaze draw) and wanted to keep it to rent as a holiday let, this is what I would do.
Though a ‘family bathroom’ would need to be fitted in somewhere.
