Planning Approval Secured - High-End Residential Extension, Cambridge
We are pleased to announce that planning permission has been granted for the comprehensive extension and remodelling of a private residence in Cambridge.
The scheme was approved by Cambridge City Council under reference 25/01208/HFUL.
Project Overview
This scheme transforms an existing dwelling into a high-quality, contemporary family home, combining generous new internal space with a refined architectural language.
The approved proposals include:
Part single and part two-storey extensions to the front, side, and rear
A complete reconfiguration of the roof form, incorporating new rooflights
A coordinated external redesign to elevate the overall appearance of the property
The result is a cohesive, design-led transformation that enhances both the functionality and architectural presence of the home.
Design Approach
The design carefully balances traditional proportions with contemporary detailing, creating what the planning officer described as a “fusion of period with modern in a sympathetic manner”
Key architectural moves include:
A more symmetrical front elevation, improving the property’s street presence
A stepped side extension, ensuring the development reads clearly as a subordinate addition
A refined material palette combining brickwork and light render, reducing visual mass and improving contextual response
This approach allowed the scheme to sit comfortably within a varied streetscape, where there is no strict architectural uniformity.
Planning Strategy
A key part of the success of this project was the planning strategy adopted from the outset.
A fallback position was established through permitted development (prior approval not required for a similar rear extension)
The design was then developed collaboratively with the Local Authority, incorporating targeted amendments to improve materiality and massing
The scheme was positioned to demonstrate full compliance with Cambridge Local Plan policies 55–59, covering design quality, context, and residential amenity
This dual-track approach strengthened the application and provided a robust basis for approval.
Planning Insight
“Establishing a fallback position early allowed us to confidently push the design quality while maintaining a strong planning position.”

Context & Impact
The site benefits from a corner plot location with established tree coverage, which helps to:
Soften the visual impact of the extensions
Shield the development from wider public views
Maintain the character of the surrounding streetscape
Importantly:
No neighbour objections were received
The scheme was found to have no unacceptable impact on privacy or amenity
Outcome
Planning permission was granted in full, with the Local Authority confirming that the proposal:
Responds appropriately to its context
Delivers a high-quality design
Preserves residential amenity
Complies with all relevant planning policies
The project was overseen by Michael Koutra and led by Architect Monica Theo, bringing together extensive experience in the delivery of high-end residential architecture. MSK Design adopted a highly coordinated, design-led approach, combining creative refinement with a robust understanding of planning policy. This proved instrumental in navigating Cambridge’s sensitive approach to residential development and securing a successful outcome.
