Why Homeowners Choose Single Storey Extensions
Single-storey extensions offer several advantages over other types of home expansion. First, they maintain the original structure’s appearance while adding usable space. This type of extension works perfectly for creating open-plan kitchens, larger living areas, or extra bedrooms. Unlike loft conversions or two-storey extensions, single-storey projects are quicker to build, reduce structural risks, and often fall within planning regulations, making approvals easier.
Streatham Park is a highly sought-after location in Wandsworth, with homes ranging from Victorian terraces to modern semi-detached houses. Property owners here often want to maximize their space while maintaining the charm of the neighborhood. A thoughtfully designed single-storey extension achieves that balance by blending style, practicality, and value.
Planning Your Single Storey Extension
Planning a single-storey extension starts with evaluating your property’s potential. You need to consider your plot size, garden space, and the position of existing structures. Many homeowners in Streatham Park aim for rear extensions, as they preserve the front façade and enhance backyard usability. Side extensions are also popular for creating additional rooms without affecting outdoor space too much.
Before construction begins, check local Wandsworth Council regulations. Planning permission may not always be required for a single-storey extension, but certain limits on height, length, and proximity to boundaries must be respected. Hiring a professional architect or extension specialist can help navigate these rules efficiently.
Design Tips for Maximum Impact
The design of your single-storey extension affects both appearance and functionality. Here are key design considerations:
-
Natural Light: Large windows, bi-fold doors, and skylights bring in sunlight, creating an airy, spacious atmosphere.
-
Open-Plan Layout: Integrating the extension with the existing living space fosters connectivity and maximizes usable area.
-
Matching Materials: Use materials that match your original structure, like brick, render, or timber cladding, to maintain aesthetic consistency.
-
Energy Efficiency: Incorporate insulation, energy-efficient windows, and sustainable heating solutions to reduce running costs and enhance comfort.
-
Outdoor Integration: Design doors and patios that link seamlessly with your garden, encouraging outdoor living and entertaining.
A well-designed extension doesn’t just add space—it transforms how you live in your home.
