Residential Extensions in Cornwall
Extending your home is one of the most effective ways to gain additional space while remaining in a location you love. KS Architects specialise in residential extensions across Cornwall, delivering carefully considered designs that respond to planning policy, site constraints, and the practical realities of construction.
​
Every extension project begins with a clear understanding of how you want to use your home. We focus on improving natural light, spatial flow, and energy efficiency while ensuring the proposal sits comfortably within its surroundings.
​
Our experience with local planning authorities allows us to develop proposals that are robust, well-reasoned, and more likely to achieve approval.
From early feasibility studies through to planning, technical design, and construction support, we guide you through each stage with clarity and confidence.
​
If you are considering a house extension in Cornwall, KS Architecture can help you unlock the full potential of your property.
