• Windows finished in a uPVC would be only considered acceptable where it matches the original style, design, proportions and colour of the window to be replaced
• Varying materials on a single elevation will not be supported.
• External glazing bars or external leading will be required to match that of the original window arrangement.
• Window sight lines are to be equally set.
• New window openings to the front street facing elevations will only be acceptable where it can be demonstrated that these would not have a negative impact on the values and amenities of the property or street scene.
• The finish and colour of window frames and casements should match the original windows.
• The style, design and colour of proposed windows at the rear ground floor level and where not visible from a public vantage point, can have a more relaxed approach– e.g. bi fold doors will generally be accepted.
