New build inspections across Walmley, Minworth and the 5,500-home Langley development








B76 covers Walmley village, Minworth and the surrounding parts of Sutton Coldfield - an area that is about to undergo the most significant housing transformation in its history. The Langley Sustainable Urban Extension has received planning approval for approximately 5,500 new homes on land adjacent to Walmley, with strategic infrastructure works beginning in late 2025. When complete, Langley will house around 14,000 people - almost doubling the ward's current population of 16,318.
The current B76 average house price sits at £332,000 (Rightmove), with detached homes averaging £466,000 and semi-detached at £321,000. The Home Builders Federation reported in March 2025 that 93.7% of new build buyers found defects, with research from Coventry University recording 141 faults per property on average. At this scale of development, professional snagging surveys are not just advisable - they are the only practical way to ensure build quality keeps pace with construction volume.

The Langley Sustainable Urban Extension is one of the largest housing developments in the West Midlands. Approved as part of the Birmingham Development Plan, it will deliver approximately 5,500 new homes on land adjacent to Walmley, along with schools, community facilities, employment space and green infrastructure. Over a third of the homes - around 2,000 - will be classified as affordable, including shared ownership and first-time buyer properties.
Strategic infrastructure works gained approval in late 2025, including demolition of existing structures at Langley Park House, engineering earthworks, highway construction and cycle and pedestrian networks. The build-out will span 15 to 20 years, meaning B76 will see continuous new build activity through the 2020s, 2030s and into the 2040s.
With multiple developers building across such a large site over many years, construction quality will inevitably vary. Different phases may use different subcontractors, materials and construction methods. Early phases often face additional challenges from ongoing earthworks, drainage installation and road construction nearby, which can affect ground settlement, external finishes and landscaping around individual plots. A snagging survey gives each individual buyer documented evidence of the condition of their specific property at handover, regardless of which developer or phase they are purchasing from.
Our local surveyors cover every new build in the B76 postcode, from the existing New Hall Manor Estate through to the earliest phases of Langley. The inspection is tailored to the construction type and developer.

The Langley scheme will see thousands of homes built by multiple developers over 15 to 20 years. Large-scale phased developments create specific snagging risks: subcontractor turnover between phases, time pressure to meet completion targets, and inconsistent quality supervision across different plots. The Home Builders Federation found that 93.7% of new build buyers report defects, with over a quarter discovering more than 15 snags. On a development of 5,500 homes, that translates to an estimated 5,000+ properties with construction issues. A snagging survey is your personal quality check on the specific property you are buying.
West Midlands pricing sits below the national average. Prices exclude VAT where applicable.
Walmley has grown through distinct phases. The original village centred on Walmley Road and St John the Evangelist Church, built in 1845. Post-war expansion turned the area from a rural parish into a suburban community, with estates spreading across former farmland towards Minworth and Thimble End through the 1960s and 1970s.
The New Hall Estate was built by Bryant Homes from the 1980s through the late 1990s on former Newhall Farm land owned by Rubery Owen Holdings. The project was considered one of the most complicated housing developments of that decade in England due to the steep terrain gradient. The newer New Hall Manor Estate followed around 2000. Warren House Farm and New Shipton Farmland were developed more recently, expanding the residential footprint further.
The Langley scheme represents the next chapter. Around 30% of the development land will be dedicated to green space, parks and recreational routes. Segregated cycle paths will connect to Peddimore via a traffic-free bridge over the A38, and new Sprint bus services are planned. Two new junctions onto the A38 dual carriageway will serve the development. The site will also include new primary schools, a secondary school and community facilities to support an eventual population of approximately 14,000 residents. For buyers in the early phases, a snagging survey ensures that the rush to establish the development does not come at the expense of individual build quality.

Choose a pre-completion inspection (before you get keys) or a post-completion visit within the first days of ownership. Pre-completion access is available from most major developers under the New Homes Quality Board code introduced in 2022.
Your qualified snagging inspector spends 2-5 hours examining every room, external area and accessible service installation. Thermal imaging identifies insulation voids and heating distribution issues invisible to the naked eye.
Within 48 hours you receive a comprehensive report listing every defect with photographs, exact locations and severity ratings. Forward it to your developer as a formal defect notification under warranty terms.
Over 2,000 of Langley's planned homes will be affordable - shared ownership, affordable rent and first-time buyer properties. These homes are built to the same standards as open-market purchases and carry identical warranty obligations. If you are buying through a housing association or shared ownership scheme, you have the same right to report defects within the two-year builder liability period. A snagging survey gives you the documented evidence to hold the developer or housing provider accountable, regardless of your tenure type.
Snagging surveys in B76 start from £295 for a two to three bedroom property. Smaller flats begin from £250, while four to five bedroom detached homes typically cost £495 or more. West Midlands pricing sits below the national average. For a property at the B76 average price of £332,000, the survey cost is less than 0.1% of the purchase price - a minor outlay against potential repair costs that can run into thousands.
Yes. As the Langley Sustainable Urban Extension begins delivering homes, our inspectors will cover every phase and every developer on the site. We will adapt our inspections to whichever construction methods the appointed housebuilders use. For early-phase buyers, a snagging survey is especially important as infrastructure and landscaping are still being completed around individual plots, which can affect drainage, access and external finishes.
A standard two or three bedroom semi-detached house takes 2-4 hours on site. Larger detached properties may need 4-5 hours. The surveyor examines every accessible room, roof space, external area and service installation. Your detailed report with photographs arrives within 48 hours of the inspection.
Yes. The New Homes Quality Board introduced formal pre-completion inspection rights in 2022. Most developers, including major housebuilders likely to build at Langley, accommodate pre-completion access. This lets the builder address defects before you collect your keys. Ask your solicitor or conveyancer to include PCI access in the purchase contract.
On high-volume sites, the most frequent defects are poor paintwork and decorative finishes (82% of inspections), ill-fitting windows and doors (67%), insulation gaps in loft spaces (54%), poorly applied mastic sealant (49%) and external brickwork issues (38%). Large-scale sites also see more variation between plots built by different subcontractor teams, so what passes inspection on one house may fail on the next.
Shared ownership and affordable housing properties carry the same builder warranties as full-market purchases. The developer is obligated to fix defects reported within the two-year liability period regardless of your ownership percentage. A snagging survey provides the documented evidence you need to enforce those rights, and many housing associations welcome independent reports as they help maintain property standards across their portfolio.
Peddimore is a 71-hectare employment development adjacent to Langley, designed to create up to 10,000 jobs in advanced manufacturing and industrial sectors. While Peddimore itself is commercial rather than residential, its proximity to Langley means increased traffic, construction activity and infrastructure changes in the B76 area. Buyers at Langley should be aware that the surrounding landscape will continue to evolve throughout the build-out period.
Send the report to your developer as a formal warranty notification. The builder must acknowledge the defects and arrange remedial work within a reasonable timeframe. Keep a copy for your records. If the developer does not respond, escalate to your warranty provider - NHBC, Premier Guarantee or LABC. We offer follow-up re-inspection visits from £150 to verify that reported defects have been properly corrected.
