New builds across DT11 need checking - our inspectors find the faults your builder won't tell you about








Blandford Forum is in the middle of one of the most active new build phases in its modern history. Taylor Wimpey's Bryanston Holt development, Bellway's St Mary's Hill neighbourhood, Ashberry Homes at St Mary's View, and Wyatt Homes' approved 490-home site northeast of town are all delivering properties across DT11. With average house prices at £377,513 and four-bedroom detached homes reaching over £503,867, these are significant financial commitments.
Our inspectors work across all the major DT11 developments, identifying faults before you complete. A standard three-bedroom new build in Blandford Forum typically generates 60 to 100 snagging items. Drainage installation quality - improperly bedded drain runs and misaligned inspection chamber covers - is one of the most consistent findings on DT11 sites, linked directly to the area's chalk and clay-with-flints ground conditions. We document every issue and deliver your written report with photographs within 24 hours, so you can hold your builder to account before you hand over your deposit.

Blandford Forum sits on chalk bedrock, with clay-with-flints deposits on the higher ground to the north and alluvial material across the River Stour flood plain. This geology matters for new build construction. Chalk is classified as a shrink-swell material, which means the ground moves seasonally as moisture content changes. On the northeast allocation site - where Wyatt Homes has planning approval for 490 homes - the transition between chalk and clay-with-flints creates ground conditions that require careful foundation design. Our inspectors check ground-floor slab condition and drainage bedding on every DT11 inspection as a result.
The active sites at Bryanston Holt, St Mary's Hill, and St Mary's View are positioned on elevated ground south of the town, away from the River Stour flood plain. Even so, drainage installation quality remains important. Improperly bedded drain runs or misaligned inspection chamber covers - findings we pick up on a significant number of DT11 inspections - can cause slow-running drainage, odours, or ground settlement within the first year of occupation. We confirm correct drainage installation on every inspection as a standard check.
All three of the main DT11 developers - Taylor Wimpey, Bellway, and Ashberry - specify solar panels, EV chargers, wastewater heat recovery systems (WWHRS), and triple glazing on their DT11 homes. Each of these systems introduces additional installation risk beyond standard brickwork and carpentry. A WWHRS unit that has not been correctly commissioned will underperform without showing any obvious outward signs. Solar panels mounted with incorrect fixings or connected without proper earthing create both performance and safety concerns. Our inspectors are trained to check commissioning documentation and installation quality on all these systems.

The River Stour has flooded Blandford Forum repeatedly, with the peak recorded level reaching 2.78 metres on Christmas Eve 2013 - the highest on record. While the Bellway, Ashberry, and Taylor Wimpey developments are sited on higher ground away from the flood plain, all DT11 buyers should confirm that drainage connections discharge correctly and that surface water is fully separated from foul drainage. Our inspectors verify drainage installation quality on every DT11 inspection, checking that inspection chamber covers are correctly set, drain runs have adequate fall, and no cross-connections exist between surface water and foul systems.
Our inspectors cover every accessible area of your new home in a single visit, working to NHBC technical standards and the Consumer Code for New Homes. We know what builders are required to deliver and where they consistently cut corners. A typical DT11 inspection of a three-bedroom semi-detached home takes 2.5 to 3 hours and produces a written report with photographic evidence indexed to each room and area of the property.
Our report is structured so you can send it directly to your developer's customer service team. Taylor Wimpey, Bellway, and Ashberry all have formal pre-completion defect resolution processes, and a properly structured snagging report accelerates that process considerably. We flag which items require immediate attention before completion and which are acceptable to rectify in the standard defects period.

Tell us your property type, DT11 postcode, and your anticipated completion date. We confirm inspector availability and send a fixed-price quote within the hour - no hidden charges.
Our inspector is given details of your specific development - Bryanston Holt, St Mary's Hill, St Mary's View, or another DT11 site - and any known build-specific concerns before the visit. Local knowledge matters.
Our inspector visits your new home 2 to 5 days before your completion date, spending 2 to 4 hours on site depending on the property size. You're welcome to attend the inspection.
You receive a full written report with room-by-room photographs of every defect within 24 hours. The report is formatted to send directly to your developer's customer care team.
Your inspector is available to clarify any item in the report with your builder. Where defects are not resolved before completion, your NHBC Buildmark warranty and the Consumer Code for New Homes provide formal redress routes.
Blandford Forum has an unusual construction history. The town was almost completely destroyed by fire on 4 June 1731, and an Act of Parliament required that it be rebuilt in brick and tile rather than timber - a mandate enforced by the Bastard brothers, the local architects who designed much of the Georgian town we see today. The result is that while most of Dorset builds in flint or limestone, Blandford Forum is a brick town, and has been for nearly 300 years.
Modern DT11 new builds continue that brick tradition. Taylor Wimpey, Bellway, and Ashberry all use brick cavity construction on their Blandford sites, finished with either brick slips or rendered sections. Our inspectors check brick cavity work in detail: wall tie density and placement, perpend alignment, DPC weep hole provision, and the quality of any brick-to-render junctions. These checks catch problems that can lead to damp penetration or structural cracking within the first five years.

Snagging survey costs in Blandford Forum and the wider Dorset area typically run from £295 for a small apartment to £499 or more for a larger five-bedroom house. For a three-bedroom home on one of the main DT11 developments - Bryanston Holt, St Mary's Hill, or St Mary's View - expect to pay in the £395 to £450 range. Prices vary between providers based on inspection depth, experience, and report format. Homemove provides a fixed price upfront with no add-ons: use the quote tool on this page for an exact figure for your property type and postcode.
Every new build in DT11 benefits from an independent snagging inspection, regardless of the developer or price point. The active sites as of early 2026 include Taylor Wimpey's Bryanston Holt on New Road in Lower Bryanston (75 homes from £369,995), Bellway Homes' St Mary's Hill in Blandford St Mary (part of a 350-home neighbourhood with prices from £449,995), and Ashberry Homes' St Mary's View on the same southern site (143 homes from £278,995 to £494,995). Wyatt Homes' approved 490-home development northeast of town adds further phases from 2024 onwards. All these sites carry NHBC Buildmark warranties, but the warranty is not a substitute for a pre-completion snagging inspection.
A standard inspection of a two or three-bedroom home on the main DT11 sites typically takes 2 to 3 hours on site. A four or five-bedroom detached home on the larger plots can take 3 to 4 hours. The inspection covers every accessible room, the loft space, external elevations, and drainage connections at the property boundary. Your written report with photographs is delivered within 24 hours of the inspection completing, so there's no long wait before you can approach your builder.
In homes built on the chalk and clay-with-flints geology around Blandford Forum, drainage installation problems are among the most site-specific findings: improperly bedded drain runs, misaligned inspection chamber covers, and incorrect surface water separation. Beyond ground-related issues, the standard new build defect list applies: incomplete or patchy plasterwork, tiled areas with cracked grouting or silicone applied over wet surfaces, doors and windows that won't sit square in their frames, and paintwork defects across ceilings and walls. On developments with WWHRS units and solar panels - specified at Bryanston Holt, St Mary's Hill, and St Mary's View - we also check installation quality and that commissioning records have been properly completed.
Yes, and this is the recommended approach. A pre-completion inspection means every defect is documented before the keys change hands, putting you in the strongest position when requesting remediation from the builder. Most developers, including Taylor Wimpey, Bellway, and Ashberry, will permit access for an independent pre-completion snagging inspection - if they refuse access, this can itself be escalated under the Consumer Code for New Homes. We recommend booking your inspection 3 to 5 days before your anticipated completion date to allow time for the report to reach the builder's customer service team.
Yes. The NHBC Buildmark warranty covers structural defects for 10 years and builder-responsible defects during the first 2-year builder period, but it does not conduct an independent inspection of your home before completion. The warranty provides a dispute resolution mechanism after problems become visible - a snagging survey finds them before they develop further or before you've had a chance to use the builder's goodwill. Many items identified in snagging reports are cosmetic or functional defects that fall below the NHBC's structural intervention threshold. Getting these rectified before or shortly after completion, rather than living with them for months, is far less disruptive.
Our snagging inspections assess the physical condition of the property rather than flood risk designation - that assessment comes from your solicitor's environmental and flood searches alongside the Environment Agency's flood map. However, we do check drainage installation quality on all DT11 inspections as a standard item, which is directly relevant to how a property manages surface water and foul drainage. Given the River Stour's flooding history - with a peak level of 2.78 metres recorded in December 2013 and multiple flood events since 2000 - correct drainage installation on all Blandford Forum new builds matters, even for the higher-ground developments away from the immediate flood plain.
Snagging surveys are designed for new build properties. For resale homes - including the Georgian and Victorian terraced houses in Blandford's historic town centre, the inter-war semis on the western side of town, or the post-war estates on the northern and eastern fringes - a RICS Level 2 HomeBuyer Report or Level 3 Building Survey is the appropriate inspection. Blandford's Georgian stock, with its solid brick walls, original sash windows, and timber floors, typically warrants a full Level 3 Building Survey.
