There has never been a better time to go back to basics in the care of buildings. To sell a building advantageously in a difficult market it needs to be as free from defects as possible. In a booming market anything went. Now we are back to very careful due diligence and a building defect can unsettle a sale. We will see the number of flagship new building projects diminish as the economy declines but now is not the time to neglect an existing building whether old or relatively new. Dilapidation claims at the end of a commercial lease can be crippling. A stitch in time saves nine.
