Our approach is heritage-led first.

The proposed windows need to sit comfortably within the character of the property and the wider street scene. That means paying close attention to the details that conservation officers and planning departments often care about: timber sections, external profiles, glazing bars, meeting rails, proportions, colour, finish and the relationship between the new windows and the original architecture.

At the same time, many of our clients are replacing their windows because of serious noise problems from traffic, aircraft, trains, neighbours or busy urban streets.

This means the window specification also needs to meet acoustical requirements. The challenge is to improve comfort inside the home without creating a design that feels visually heavy, inappropriate or out of keeping with the building.

Because we design and manufacture bespoke timber acoustic windows, the planning drawings and supporting information are based on the actual windows we intend to build. The design is not a generic drawing produced separately from the final product. It is connected to the proposed timber profile, glazing specification, sightlines and acoustic requirements from the beginning.

Our planning application support is available where planning permission is required for window replacement, particularly in cases involving:

Where the external appearance of the windows may need to be preserved or enhanced to preserve the character of the area.

Where permitted development rights may have been restricted, and window changes may require a formal application.

Where the proposed window design will be visible from the street or forms part of the architectural character of the property.

Our fixed-fee planning support service can include:

Our full window-related planning application support service starts from £900 + VAT.

This covers our preparation, documentation and submission work for the window-related planning application.

This does not include:

First, we confirm the proposed window design and specification. This includes the window style, material, external appearance, glazing pattern, sightlines, colour, finish and acoustic requirements.

Once planning permission is known to be required, and you would like us to manage the application, we begin preparing the relevant window-related planning information.

We prepare the required drawings, section details, technical specification and supporting information for the proposed window replacement.

Heritage-sensitive window replacement needs more than a standard product.

The appearance of the window has to respect the building. The proportions need to feel right. The profiles, glazing bars, timber sections and external finish need to make sense for the property.

For acoustic projects, there is another layer of complexity. The windows also need to help address the reason the client is replacing them in the first place: noise.

Our planning support brings these two requirements together. We prepare the application around the actual timber acoustic windows or secondary glazing system proposed for the project, helping to keep the design intent, planning information and final manufactured product aligned.

The aim is simple: a well-considered window proposal that respects the character of the property while improving the comfort of the home.

If planning permission is required for your conservation area or Article 4 window replacement, we can prepare and submit the window-related planning application on your behalf.

Our fixed planning support fee starts at £900 + VAT, excluding council fees, Planning Portal charges, and third-party costs.
