Plots are priced between £310,000 and £400,000 depending on size and position. Build costs depend on size, specification, and route chosen. For guidance, finished home values at Piddington are likely to range from £650,000 to £1.2m. We’ve published two worked examples
— a £585,000 1 -3-bed home and an £865,000 4-bed family home — on the Piddington Project page.
A plot reservation is £3,000, held on solicitor account. Buyers will also need to be genuinely committed to designing and building their own home (these are strictly for self-build, not speculative resale), provide mortgage confirmation through Buildstore or evidence of funds, and be ready to move forward when sales open.
Specialist self-build mortgages cover both the plot purchase and the build, with deposits from around 5%. Cost-based mortgages are available up to 95% LTV for plot and build combined. Funds are released in stages, against build milestones rather than as a single advance — meaning the build is properly cash-flowed throughout, and most buyers stay in their current home rather than living on a building site.
The specialist rate covers the build period only — typically a year or so. Once your home is complete, you remortgage onto a standard residential product at high-street rates. The current drawn-down rate from our partner Buildstore is approximately 6–7%.
Our partner broker Buildstore has a panel of specialist lenders ready to lend against plots at our site.
Yes — and many of our buyers do exactly that. Self-build mortgages release funds in stages as the build progresses. The progress milestones built into the mortgage mean you finance each phase of the build as it happens, rather than paying everything up front or selling your existing home before construction begins.
Information specific to Piddington — Napton dimensions will be confirmed in 2027.
Homes can be up to two storeys, with a maximum ridge height of 10m and eaves height of 5.5m.
Maximum house footprints range from 150m² to 275m² depending on plot, with internal floorspace typically 150m²–450m². Generous plots allow total builds up to 550m² (plus any non-habitable outbuildings and garages you design within the defined build zone). Most buyers design homes of 3 to 5+ bedrooms — often with home offices, open-plan living, and detached garages.
The Plot Passport is a one-page summary for your specific plot, written in plain English. It covers dimensions, build envelope, orientation, and any plot-specific constraints — and is provided to you on plot reservation.
The Design Code is the project-wide framework for what can be built — materials, heights, build zones, privacy, boundary treatments — agreed with the local authority. Design within the Code, and your detailed planning application has effective certainty of approval, subject to discharge of any conditions.
Both routes work well, and most buyers know within a few conversations which suits them best.
Architect-led traditional builds offer maximum design freedom and bespoke architecture, with 12–18 months typical build time.
Turnkey custom-build offers fixed price, fixed timeline, and a single point of contact — with 6–9 months total.
Your design team — architect or turnkey partner — prepares a detailed planning application for your specific home, within the framework of the Design Code. The local authority reviews it against the Design Code criteria before issuing their decision (statutory eight-week timeframe once planning application has been validated). Because your design follows the agreed Design Code, you have effective certainty of approval, subject to the discharge of any planning conditions.
— Ground investigations and technical surveys complete
— Boundary fencing ready for hedge planting
— Mains water, electricity, drainage, and fibre broadband to the plot boundary
— A Design Code agreed with the local authority
— Full planning permission for the site (meaning you only need to submit detailed designs for your home — see Design Code)
— Private estate road, kerbs, verges, hard landscaping and shared green spaces
— Sustainable surface water drainage system serving the whole site
— One-hectare wildflower meadow with mown paths (Piddington-specific)
— Direct pedestrian connectivity to the wider footpath network and Salcey Forest
As soon as your plot purchase has completed and you have detailed planning approval. Site infrastructure at Piddington is due to complete in Summer 2026, with plot sales completing shortly after. Most buyers run conveyancing and the detailed planning application in parallel, so the runway from plot reservation to breaking ground is typically three to six months.
We don’t impose a strict deadline, but each self-builder should plan to deliver their home within around 12 months to safeguard the site amenity for the whole community. Modern off-site construction methods make this very achievable — turnkey homes typically reach watertight in days and complete in 8–12 weeks.
Purchasers who use a self-build mortgage will have progress milestones baked in, meaning people can stay in their current home until their new home is finished.
Every plot owner becomes an equal shareholder in the management company on completion. The company owns and maintains the estate road, the drainage, the wildflower meadow, and the landscaped public spaces in perpetuity. It’s a small responsibility shared between neighbours, with an annual fee of circa £400 per plot to cover ongoing maintenance.
Your home will be a normal freehold property and you can sell it like any other home. Significant extensions or alterations after completion will need planning permission and should remain within the Design Code, to protect the character of the community as it evolves. The CIL exemption for self-build homes requires that you live in the home as your primary residence for at least three years after completion.
