West Sussex Property Market Overview
West Sussex property prices reached £435,000 average in September 2025, representing 4.5% annual growth. This performance outpaces many UK regions, reflecting sustained demand for Sussex living. The market peaked in November 2022 at £388,692, and current values sit approximately 2% below that peak, suggesting stable pricing after previous rapid increases.
New builds command premium prices compared to older stock, but offer advantages that justify the difference. Modern construction standards deliver superior energy efficiency, reducing ongoing utility costs significantly. Ten-year NHBC warranties protect your investment, whilst contemporary layouts suit modern living better than many period properties. These factors combine to make new builds attractive despite higher initial costs.
First-time buyers benefit from Help to Buy schemes on new developments, making home ownership achievable with smaller deposits. These government-backed programmes significantly improve affordability calculations, allowing you to step onto the property ladder in desirable locations that would otherwise remain out of reach. Many developers also offer part-exchange deals on existing properties, simplifying moves.

Key Development Locations
Horsham continues attracting major development activity, with multiple sites delivering hundreds of new homes. The town's excellent railway connections to London (under 60 minutes), combined with market town character and South Downs access, make it highly desirable. Meadow View by Bruckland Developments exemplifies the type of development transforming Horsham's suburbs, providing modern family homes within commuting distance of the town centre.
Crawley's position near Gatwick Airport makes it employment hub requiring substantial housing supply. New developments here serve first-time buyers and families working in aviation, logistics, and service sectors. Prices typically sit below Horsham and Chichester levels, offering better value whilst maintaining good transport links to London and the coast.
Burgess Hill benefits from significant regeneration investment, with major residential schemes transforming the town. Oakhurst at Brookleigh by Countryside Homes represents the scale of development happening here, creating entirely new neighbourhoods with schools, shops, and community facilities. The town's railway station provides regular Brighton and London services, supporting commuter demand.
Chichester and Coastal Developments
Chichester commands premium prices reflecting its cathedral city status, excellent schools, and coastal access. New developments here target affluent buyers, with specifications and locations to match. The city's planning policies emphasise design quality, meaning new builds must complement historic surroundings rather than clash with them. This results in developments that enhance rather than detract from local character.
Coastal towns including Bognor Regis, Littlehampton, and Middleton-on-Sea attract retirement buyers and families seeking seaside living. Developments here offer varied property types from apartments to detached homes, with coastal views commanding substantial premiums. The flat terrain suits older buyers, whilst beaches and water sports appeal to families.
Worthing's position between Brighton and Chichester makes it increasingly popular with buyers priced out of Brighton. New developments here fill gaps in the urban fabric rather than creating greenfield estates, maintaining the town's compact character. The beachfront location, combined with improving cultural scene, attracts creative professionals and remote workers.
Kilnwood Vale Development
Kilnwood Vale near Faygate represents one of Sussex's largest new settlements, with plans for 2,500 homes alongside schools, shops, and employment space. Harpers View by Crest Nicholson forms part of this ambitious masterplan, creating entire community from farmland. The scale allows comprehensive infrastructure from the start, avoiding the fragmented development patterns that plague many growth areas.
The development prioritises sustainability, with extensive green space, cycle routes, and public transport connections. Residents benefit from modern community facilities planned from the outset rather than added later. This holistic approach to placemaking distinguishes major new settlements from incremental development, potentially creating desirable places rather than just housing estates.
Kilnwood Vale's location provides access to Gatwick Airport employment and good road connections via the A264 and M23. This positioning attracts families wanting semi-rural environment whilst maintaining career flexibility. The development's phased delivery means the community will evolve over many years, with early buyers potentially benefiting from increasing amenity provision.
Property Types and Sizes
Two-bedroom apartments serve first-time buyers and downsizers, typically starting around £250,000-£300,000 depending on location. These properties offer affordable entry points whilst providing modern living standards. Shared ownership options extend accessibility further, allowing buyers with smaller deposits or incomes to start building equity.
Three-bedroom semi-detached and terraced homes form the core offering of most developments, priced £350,000-£450,000 across West Sussex. These properties suit young families needing space for children whilst maintaining affordability. Layouts typically provide open-plan kitchen-dining areas, separate lounges, and adequate garden space for family life.
Four and five-bedroom detached homes target established families and professionals, with prices from £500,000 to over £1 million in premium locations. These properties offer substantial space, garages, and larger gardens. The premium segment often includes bespoke finishes, high-end kitchen appliances, and landscaped gardens, appealing to buyers wanting move-in ready luxury.
Energy Efficiency and Running Costs
Modern building regulations require excellent insulation standards, significantly reducing heating costs compared to older properties. Double or triple glazing, efficient boilers, and improved airtightness combine to create warm homes requiring minimal energy input. Many buyers find utility bills 30-50% lower than equivalent older houses.
Solar panels feature on increasing numbers of new builds, either as standard or optional extras. These systems generate free electricity, further reducing running costs whilst supporting environmental goals. Battery storage systems allow you to use solar power after sunset, maximising self-sufficiency and savings.
EPC ratings of A or B come standard on new developments, compared to D or E ratings typical of older stock. This efficiency proves financially valuable as energy prices remain elevated. Future regulations may restrict mortgages on poorly-rated properties, making today's new builds better positioned for long-term value retention.
Warranties and Defect Protection
NHBC ten-year warranties protect structural integrity and provide insurance-backed guarantees that developers will rectify defects. The first two years cover everything, whilst years three through ten focus on major structural issues. This protection proves valuable if problems emerge, ensuring you're not left bearing repair costs from construction defects.
Snagging remains common issue with new builds, where minor finishing problems need addressing after completion. Reputable developers maintain dedicated teams to fix these issues, though persistent follow-up sometimes proves necessary. Engaging independent snagging inspectors before completion helps identify problems whilst leverage remains strong.
Consumer Code for Home Builders provides additional protection, requiring developers to meet service standards and offering dispute resolution if conflicts arise. This framework gives buyers confidence that problems won't be ignored, with independent adjudication available if negotiations fail. Check developers are registered before committing to purchases.
Transport and Commuting
Railway access drives much of West Sussex's appeal, with regular London services from multiple stations. Horsham, Haywards Heath, Burgess Hill, and Chichester all offer sub-90-minute journeys to London terminals, making commuting feasible if not quick. Season ticket costs must factor into budgets alongside mortgage payments when considering commuter locations.
Road connections via the M23, A23, and A27 provide access to Gatwick, Brighton, and the wider South East network. Crawley's position closest to Gatwick makes it attractive to aviation workers, whilst coastal access appeals to lifestyle buyers. Traffic congestion affects major routes during peak times, something to experience firsthand before committing to locations requiring daily drives.
Cycle infrastructure in new developments typically exceeds older areas, with dedicated routes and secure storage encouraging active travel. This proves particularly valuable for school runs and local journeys, reducing car dependency. However, wider area cycling provision varies significantly, with some towns well ahead of others on infrastructure quality.
Schools and Education
West Sussex maintains strong reputation for education, with numerous outstanding-rated primary and secondary schools. New developments often trigger Section 106 contributions funding school expansion, though places can prove tight in popular catchment areas. Research school situations thoroughly before committing to specific developments, as promised new schools sometimes face delays.
Grammar schools in Worthing and Chichester provide selective education options, though competitive entrance exams mean places aren't guaranteed. Private school options include Christ's Hospital near Horsham, Lancing College, and numerous prep schools. These choices attract families prioritising education, supporting property values in school catchment areas.
Further education colleges and sixth forms provide good post-16 options, whilst University of Chichester offers higher education without leaving the county. Brighton universities sit within easy reach for students wanting home-based study. This complete educational pathway from nursery through university makes West Sussex attractive for long-term family settlement.
Buying Process for New Builds
Reservation fees secure plots off-plan, typically £500-£1,000 refundable if you change your mind within cooling-off periods. Exchange of contracts happens when you're ready to proceed legally, with 10% deposits standard. Completion occurs when the property finishes construction, which might be months or years after reservation depending on build stages.
Choosing specifications and optional extras forms exciting part of buying new builds. Developers offer various upgrade packages for kitchens, bathrooms, flooring, and landscaping. These choices cost significantly more than DIY improvements later, but avoid disruption after moving in. Balance desire for perfect finish against budget constraints and future flexibility.
Independent legal advice proves essential, as developer contracts differ from standard property transactions. Solicitors experienced with new builds understand relevant issues and protect your interests effectively. Don't use developer-recommended solicitors without checking they're genuinely independent and working solely for you.

Making Your Decision
Buying new build property in West Sussex represents significant investment requiring thorough research.

Talk to existing residents about their experiences with developers and living in new communities. This groundwork helps you make informed decisions avoiding regrets later.
Consider total cost of ownership beyond purchase price, including commuting expenses, running costs, and service charges if applicable. Calculate whether new build premiums justify themselves through lower maintenance, better efficiency, and warranty protection. Factor in Help to Buy benefits if eligible, as these schemes significantly affect affordability calculations.
