Policy DH5
Replacement windows
Replacement windows should respect the architectural character of the building and its surroundings. It will be important that both the design and material of replacement windows match the original windows as closely as possible in terms of type and size, method of opening, profile and section, and sub-division and detailed design.
8.36 In most buildings, the detailed design of the windows is a fundamental component of the elevation and can contribute greatly to the visual character of the building. Windows are particularly vulnerable elements in that they are relatively easily replaced or altered. Where this work is not carried out sensitively, it can have a profound effect on the building, diluting its character, and detrimentally impacting upon the appearance of the general street scene.
Design of windows
8.37 The policy encourages the selection of a design appropriate to the architectural character and age of the building and includes the design attributes that would be important to consider in order to achieve a successful design of replacement window. In most cases, this would mean a design which replicates the design and material of the windows that formed part of the original composition. It may be possible to base the design of the replacement windows on those that may survive elsewhere in the building, or it may be necessary to look for examples in other buildings of the same period and style close by.
8.38 The aim of the policy is to retain the uniformity and consistency of the original design of each building, block or terrace in the borough thereby protecting the quality and architectural integrity of the building and character of the street scene from harmful incremental alterations.
