Even within a room full of 20 Economists you will find on almost any topics varied opinions (in 20 economists you will get 20 opinions) so you still will be responsible for the advice you accept and outcomes that arise.

This starting point should start within your household and involve all participants from their perspective you might be pleasantly surprised (or not) that you all have some shared ideas that overlap and adding huge expanses of dedicated space for mum, dad, grandma, the kids and the cat is not actually necessary and that many spaces can be multi functional for a better outcome.

- Consider your household budgetary constraints, how much disposable income is available to provide this swimming pool extension;
- What is the expectation in your neighbourhood. The aim should be not either the most expensive house nor the cheapest house in your street.
