Silver Willows is delivering 150 new homes on Blue Lias clay - one of the most reactive geologies in the Midlands. Get inspected before you complete.








Miller Homes' Silver Willows development on Harbury Lane (CV33 9WH) is the most significant new build project in the CV33 postcode in decades. The 150-home scheme delivers 1-5 bedroom properties from £379,950, alongside a new all-through school and a proposed country park. Plots include the Beauwood, Briarwood, Clearwood, Maywood and Whitton house types, with 4-bedroom detached homes running from £598,500 to £720,000. All homes include EV charging points, and many carry solar panels.
The development sits on Harbury Lane on the southern edge of Leamington Spa - and sits squarely on Blue Lias clay. This Jurassic formation, which runs north-east to south-west through Warwickshire, has a medium to high shrink-swell potential according to the British Geological Survey. In 2014, a section of the Blue Lias cutting near Bishop's Itchington (less than 2 miles from Silver Willows) subsided badly enough to close rail services for several days. Our inspectors check for early movement indicators on every Silver Willows inspection - this geology demands it.

The CV33 postcode sits on Blue Lias - Jurassic clay that geologists classify as having medium to high shrink-swell potential. This means the ground contracts in dry summers and expands in wet winters. For new builds, this creates real risk: door and window frames can rack and bind within the first year, floor screed can crack at movement joints, and external paving paths can settle away from threshold details. The Blue Lias cutting near Bishop's Itchington - less than 2 miles from Silver Willows - subsided in February 2014, requiring emergency Network Rail stabilisation works. Any new build buyer in CV33 should have a professional inspection before legal completion to create a baseline record of the property's condition.
Silver Willows is a Miller Homes development with 18+ plot configurations across multiple house types. Each type has slightly different structural junction details, and the Blue Lias ground conditions mean the inspectors run an extended protocol for CV33 properties compared to sites on more stable geology.
The HBF's 2025 survey found 93.7% of new build buyers nationally reported defects to their builder after moving in. At Silver Willows, getting a written, photographed report before legal completion means those defects are on record while the developer's site manager is still active on site.

Harbury is widely considered one of Warwickshire's best village communities - a designation that translates directly into buyer expectations at Silver Willows. The village sits on a Lias ridge running northeast to southwest, giving it elevated views across the Warwickshire countryside toward Southam and the Edge Hill escarpment. The village has a community shop, primary school, sports club and several active community organisations. New build buyers here are typically purchasing a lifestyle as much as a property.
At prices from £379,950 to £720,000, buyers have every right to expect exceptional finish quality. The most common defects across Midlands volume housebuilder developments in this price bracket are not structural - they are finish-level items that compound into significant inconvenience when developers are slow to remedy: poorly adjusted doors, gaps in skirtings at external wall junctions, tile grout voids, incomplete bathroom sealing, and poorly fitted kitchen units. A professional inspection creates the paper trail needed to hold the developer accountable across the full two-year NHBC warranty period. Our inspectors have worked across Warwickshire new build sites and understand the Miller Homes specification, allowing them to focus their attention on the areas most likely to present defects on Silver Willows plots.

Blue Lias is a Jurassic clay formation with medium to high shrink-swell potential. As moisture content in the clay changes seasonally, the ground expands and contracts - which places stress on foundations, floor slabs and junction details within new buildings. Doors and windows can become stiff or difficult to operate as frames rack slightly out of square. Floor screed can crack at joints. External paving can settle away from threshold details, potentially bridging the damp-proof course and allowing rising damp to enter. In February 2014 a Blue Lias cutting less than 2 miles from Silver Willows subsided severely enough to halt rail services for several days - an event that illustrates how reactive this geology is. Our inspectors follow an extended protocol for CV33 properties that specifically targets these early movement indicators, including diagonal floor levelness measurements and full door/window operation testing across the complete arc of movement.
Yes - attending is strongly recommended, especially on a large development like Silver Willows where the developer has multiple plot completions happening simultaneously. Being present means you understand which defects are cosmetic and which need urgent attention, and you can note the inspector's observations in real time. Buyers who attend their inspection typically submit more effective defect lists to their developer because they can describe the defect from their own observation, not just from a written report.
The optimal window is 2 to 4 weeks before your legal completion date. This gives the developer enough notice to remediate serious items before you hand over funds, while ensuring all fittings, finishes and systems are in place for inspection. Booking too early risks missing items that have not yet been installed; booking after completion reduces your leverage. For Silver Willows buyers reserving off-plan, we recommend booking the moment your developer confirms your completion date - slots in active development areas fill quickly, especially in the spring and autumn completion peaks.
Yes. The NHBC Buildmark warranty covers builder defects reported in the first 2 years, and structural defects for 10 years. If your developer does not adequately respond to your defect list within a reasonable time (typically 8 weeks for non-urgent items), you can escalate to NHBC's Resolution Service. A professional snagging report with photographs and written assessment significantly strengthens your position in any NHBC escalation compared to a self-compiled list of observations.
The full CV33 postcode district falls within our coverage area. This includes Harbury village, the Silver Willows development on Harbury Lane, Bishops Itchington, Deppers Bridge, the southern Leamington Spa corridor, and surrounding rural areas in Warwickshire. Any new build in CV33 - whether a large development like Silver Willows or a smaller infill plot - can be inspected within our standard turnaround times. Contact us if you need confirmation of availability for a specific address.
Miller Homes builds to a consistent specification across their regional developments, which means the inspection checklist for Silver Willows can be informed by findings across comparable Miller Homes sites. Common patterns include cavity insulation gaps at window reveals, incomplete trickle vent installation in bedroom windows, and minor plasterwork defects overpainted during snagging preparation. These are not unique to Miller Homes - they reflect the pressures of volume construction - but knowing the patterns helps our inspectors look in the right places and document findings precisely.
Yes. Silver Willows homes include EV charging points, and many include solar panels - both are included in our inspection scope for CV33 properties. We check EV charger installation for correct fuse rating, weatherproofing at the cable wall entry, and commissioning documentation. For solar panels, we inspect roof penetration flashings, panel alignment and tilt angle, and verify that commissioning certificates and MCS documentation have been provided. These are often omitted from a developer's own pre-completion checks.
