Context and design principle for extensions and alterations

An extension or alteration to a residential property should be designed to become an integral part of the property both functionally and visually. Such works should not be designed in isolation solely to fit in a required amount of accommodation. Proposals that are badly sited or designed, or that are incompatible with their surroundings, can lead to an undesirable change in the character of the existing property and the area in which they are located. Success depends upon striking the right balance between adaptation and sensitivity to the original design.
