I'm honestly not sure what started this insanity but like all new home builders it seemed like a good idea at the time.
If you really give it some thought you'll realise you've just handed a perfectionist endless choices on a 6 - 12 month project about which they can obsess, agonise, make decisions, regret decisions and permanently drive their partner nuts with "What if...?", "Do you like...?" and "It will be worth upgrading...".
If you can't relate, I envy you and I'm the picky one!
