Alfred who is a carpenter contracts with Lee to make 4 wooden doors, 4 frames, 6 chairs and a table in 30 days in Lee's work shed in the forest. The items are to be made out of a very rare wood. The price agreed upon is HK$150,000, to be paid on delivery of all items before the expiry of the 30-day period. Alfred invests his money in buying the material and the rare wood required and has it delivered to Lee's work shed. (No further stock of the rare wood is available in Hong Kong). By three weeks, he has been able to complete making 4 wooden doors, 4 frames and 1 chair. Alfred delivers these finished articles to Lee. Unfortunately, on the 22nd day, due to an extended period of temperatures, the forest catches fire and Lee's work shed is burnt. Alfred returns to find ashes and a few pieces of metal. He, anyway, goes to Lee to demand payment for the work done and the cost of the wood and other materials, which had been destroyed in the fire. Advise Alfred as to his legal position.
