New build properties are less likely to require works or maintenance at the point of purchase than an older property. Energy and heating bills may also be cheaper since new homes are more efficient and better insulated.
If you are buying your home off-plan (before it has been built) then you will often have some input into some of the design features of the house.
Many fixtures and fittings which you would normally expect to pay for in an older property are already installed in new build properties. For example, double or triple glazed windows, insulation, energy efficient heating and white goods such as dish washers are often already present in new build properties.
