Historic buildings require careful design. Whether a property is listed or located within a conservation area, any extension or alteration must respect the character of the building and its surroundings while meeting modern standards for safety, access and usability.
At Rosenkelly Architectural Design we regularly work with historic structures across Dorset, helping clients unlock the potential of older buildings while navigating the planning process.

Working with Historic Buildings
Many historic buildings were not designed for modern use. Circulation can be inefficient, access can be difficult and fire escape routes may not meet current standards.
Through feasibility studies and early design exploration we assess how a building can be improved while retaining its historic character. This often involves careful internal reconfiguration combined with modest external interventions.
Recent work has explored how a new stair extension could be introduced to a historic structure to replace an existing steep stair that no longer meets modern escape standards. The design reused traditional materials including local stone, slate roofing and sash windows to ensure the extension remained consistent with the character of the building and the surrounding historic setting.

Extensions in Conservation Areas
Properties within conservation areas require particularly sensitive design. Planning authorities will assess whether proposals preserve or enhance the character of the area.
Successful projects often focus on a simple approach:
Extensions positioned to the rear of the building where possible
Materials that match or complement the existing structure
Proportions and window rhythms that reflect traditional forms
Clear distinction between original fabric and new additions
When handled correctly, extensions can improve the functionality of historic buildings without harming their heritage value.
Navigating Planning and Heritage Constraints
Projects involving listed buildings or conservation areas may require additional information to support planning applications. Depending on the scheme this could include:
Heritage impact statements
Structural engineering input
Ecological surveys
Access strategy or fire safety improvements
Early feasibility work helps identify these requirements and reduce risk before progressing to a full planning submission.

Feasibility Studies for Heritage Buildings
A feasibility study is often the best first step when considering works to a historic property. It allows the building to be assessed spatially and helps identify realistic options before committing to detailed design.
This approach provides clarity on what may be achievable and helps guide the most appropriate route toward planning consent.
