A builder contracted to renovate a house for a total price of $850,000. Can the builder claim payment where:

a)the builder did some of the work, worth $370,000, but then abandoned the contract?

b)the builder finished the job but some of the work, particularly in the main bedroom was not done to an acceptable standard - the change room doors and drawers were not straight?

c)the builder arrived on time to start the job, but the client had a change of mind and sent the builder away?
