Your Planning and Design Partners
Looking to add space, style, and value to your home?
Are you planning a house extension in Spelthorne? Whether you’d like to create a larger kitchen-diner, add a practical home office, or design a family room that opens directly to the garden, extending your home is one of the most effective ways to gain more space while increasing property value.
At Fluent Architectural Design Services, we provide design and planning from the very beginning. Our in-house team manages every stage — from precise surveys and bespoke layouts to planning applications, building regulations, and structural calculations. With everything handled under one roof, your project is efficient, coordinated, and stress-free.
Why Extend Your Home in Spelthorne?
Spelthorne is a well-connected borough, with excellent transport links via the M3, M25, and direct trains into London Waterloo. From riverside homes in Shepperton and Sunbury, to family houses in Ashford and Staines, extending is a popular way for homeowners to stay in the area they love while tailoring their property to modern needs.
Typical house extensions in Spelthorne include:
-
Rear extensions to create open-plan kitchen and family living spaces.
-
Double-storey extensions for additional bedrooms and bathrooms.
-
Side extensions and garage conversions for practical utility or home office space.
-
Garden-facing extensions with large glazing, skylights, and bifold doors.
Because parts of Spelthorne sit within the Green Belt, flood zones, and riverside areas, planning can sometimes be more complex. Our in-house planning consultants (including ex-local authority officers) ensure your project complies with Spelthorne Borough Council’s requirements while still maximising your home’s potential.
