Single storey extensions remain the most popular building project we undertake across Horsham—and for good reason. They deliver substantial additional living space without the complexity and cost of building upward, often falling within permitted development rules that avoid planning application delays entirely.
Whether your family needs a generous kitchen-diner where everyone gathers, a bright living room opening onto the garden, a dedicated home office away from household distractions, or simply breathing room in a house that’s grown too cramped, a single storey extension provides the answer.
We design and build single storey extensions across Horsham and West Sussex, creating spaces flooded with natural light through bi-fold doors, skylights, and carefully positioned glazing. Each extension complements your existing property while delivering the transformation your family needs.
From initial design through to final decoration, we manage every aspect of your project. Contact us to discuss your requirements and arrange a free consultation.
Extending into your rear garden creates the additional ground floor space most Horsham families need. Rear extensions suit kitchen enlargements, living room expansions, and open-plan reconfigurations connecting indoor and outdoor living seamlessly. Under permitted development rights, you can typically extend three metres from attached houses or four metres from detached properties without planning permission—larger extensions up to six or eight metres remain possible through prior approval notification. We design rear extensions maximising natural light through bi-fold doors, sliding systems, and roof glazing while ensuring the addition complements your property’s existing character. Properties across Roffey, Littlehaven, and Southwater regularly extend rearward to transform cramped ground floors.
The kitchen-diner has become the heart of modern family life—cooking, eating, homework, socialising all happening in one flowing space. Single storey kitchen extensions create room for this lifestyle, accommodating islands for food preparation and casual seating, dining tables for family meals, and comfortable areas for relaxation. Bi-fold or sliding doors connect your new space to the garden, perfect for summer entertaining and flooding interiors with light year-round. We coordinate extension construction with kitchen installation, ensuring seamless delivery from groundwork through to fitted units and finishing. Properties across Broadbridge Heath, Warnham, and Billingshurst transform through kitchen-diner extensions that revolutionise how families live together.
Modern families want flowing, connected spaces rather than compartmentalised rooms previous generations preferred. Single storey extensions combined with internal wall removal create the open-plan living areas contemporary lifestyles demand. Kitchens connect to dining spaces connecting to living areas in one generous, light-filled room. We install steel beams supporting structural openings while coordinating the extension build, delivering comprehensive transformation rather than piecemeal changes. Careful design maintains distinct zones within open-plan spaces—cooking areas, dining spaces, relaxation zones—while allowing the connected flow families desire. Properties throughout Horsham benefit from open-plan extensions that fundamentally reimagine ground floor living.
Remote working has become permanent for many Horsham residents, yet spare bedrooms and kitchen tables make poor long-term offices. A purpose-built single storey extension creates dedicated workspace with proper separation from household life, appropriate lighting for screen work, and professional environments for video conferences. Ground floor offices offer easy access without navigating stairs, suit accessibility requirements, and can incorporate separate external entrances for client-facing businesses if needed. We design home office extensions with comprehensive electrical provision, data connectivity considerations, and climate control for year-round productivity. Properties across Storrington, Pulborough, and Mannings Heath add dedicated offices that make remote careers genuinely sustainable.
Single storey extensions appear straightforward but demand genuine expertise. Foundations must suit ground conditions—clay soils common across West Sussex require particular consideration. Structural connections between new and existing building need proper engineering. Roof junctions must prevent water ingress for decades. Drainage requires careful planning. Getting these fundamentals wrong creates problems lasting years.
Our service covers everything—planning applications or permitted development assessment, structural engineering coordination, groundwork, construction, roofing, glazing, electrics, plastering, and decoration. One team managing every element means nothing falls between gaps.
We build single storey extensions throughout Horsham and surrounding areas including Roffey, Littlehaven, Broadbridge Heath, Southwater, Warnham, Billingshurst, Storrington, Pulborough, Rusper, Slinfold, Mannings Heath, Lower Beeding, and surrounding West Sussex villages.

Your roof space contains potential waiting to be claimed. Loft conversions create bedrooms, offices, bathrooms, and flexible rooms without touching your garden or extending your footprint. Dormer builds maximise headroom, Velux installations suit simpler requirements, and hip-to-gable alterations recover space lost to sloping roofs. We address structural requirements, insulation, wiring, and interior finishing throughout. Most Horsham loft conversions complete within six to eight weeks. Consider whether loft conversion alongside garage conversion could deliver the complete transformation your property needs.
loft conversions
Create versatile extra space in your garden rather than converting existing structures. Garden rooms provide dedicated home offices, gyms, studios, or annexe accommodation as standalone buildings designed for year-round use. Full insulation maintains comfortable temperatures whatever West Sussex weather delivers. Quality double glazing, efficient heating, and proper ventilation create spaces performing like any room indoors. Most garden rooms fall under permitted development, avoiding planning delays. Compare garden room and garage conversion options to determine which approach best suits your requirements.
When garage conversion alone won’t provide sufficient space, a house extension delivers the room your family needs. We design and build single storey, double storey, and wraparound extensions across Horsham, creating kitchen-diners, additional bedrooms, expanded living spaces, and more. Every extension complements your existing property while maximising new accommodation. Full project management covers planning applications, structural engineering, and coordination of all trades from groundwork through to finishing. Sometimes combining garage conversion with modest extension delivers the optimal solution for growing families.
