For private individuals, businesses and public authorities, property is the single most important asset. Buildings typically account for a significant percentage of the total value of companies, whilst most people's major possession is their home. When commissioning a new building, extending an older one, or planning repairs or maintenance, the choice of the builder is therefore critical. As the client, you need - and have the right - to be sure that the work, when completed, will represent a good investment and value for money.
