You cannot put a price on a backyard space for kids. .
Yes - this is what is most disappointing for us - our block is 800 sqm - almost twice as much as the average block in this estate (there are only 3 other blocks this size). If could not get a block this size we would not have done it - we would have bought a townhouse or single frontage house much closer to the city and lived with it. We often said to the builder and the landscape designer that the most important part of the house for us was the yard. Everything else was secondary - we even changed the builders original plans to shorten the house so that we could have more backyard. We wanted some space for the kids to run around in while they are little. We have always planned to move closer to the city and a small block when the backyard is less important to them.
