Bespoke New Builds in Calstock
A bespoke new build is the longest project we do, and the most rewarding. From plot appraisal through planning, building regulations and construction, you work with one team from the first sketch to the handover walk-round. The Calstock version of this work has its own character — Calstock is a creekside settlement in the PL18 area, with waterside homes, wooded valleys and narrow-lane access shaping the brief, with a building stock that leans toward waterside homes and detached houses.
Calstock sits in East Cornwall — covering PL18 from Callington, Stoke Climsland, Linkinhorne outward.

Who this is for
Calstock runs the full mix — owner-occupier, holiday-let, commercial and the occasional smallholding — so we scope every new build enquiry from the use-class up.
Local context
Why Calstock is its own job.
Creekside ecology, flood risk, trees and views across the water often matter as much as the building form itself. For new build specifically, parts of Calstock sit within a designated Conservation Area, which means materials, fenestration and roof pitches all need to read sympathetically with the existing streetscape; the wider area forms part of the Cornish Mining World Heritage Site, which adds a heritage assessment layer to most material changes. So every Calstock job runs as a PL18-specific piece of work — local policy, local fabric, local builders. Most of our new build work in Calstock lands on waterside homes, with detailing that has to nod to the wider Stoke Climsland streetscape.
Planning note
Cornwall's planning policy on new dwellings is among the most restrictive in England outside Greater London. The first conversation should be a planning conversation, not a design one.
What we focus on
New Builds considerations specific to Calstock.
01
Self-build CIL exemption requires the right documentation in the right order; missing a step costs five-figure sums.
02
Cornwall's housing policy increasingly favours principal residence and replacement dwelling schemes over open-market new builds in some parishes.
03
Off-grid services — package treatment plants, borehole supply, off-mains gas — are common on rural Cornish plots and need designing, not assuming.
04
Replacement dwellings have specific volumetric tests — getting the ratio between existing footprint and proposed floor area right is the difference between approval and refusal.
Our process
How a Calstock new build project runs.
Step 1
Plot review
Site visit, planning history check, designation review and an honest feasibility verdict.
Step 2
Concept design
Sketches that test the plot in massing, orientation and approach before any drawings are committed.
Step 3
Planning
Pre-app, full planning, consultee management and condition discharge.
Step 4
Technical design and build prep
Building regs, structural design, services strategy and contractor procurement.
Step 5
Construction and handover
Build delivered under contract administration with regular client reviews.
Most bespoke new builds run eighteen to thirty months from instruction to keys, depending on site, planning route and build complexity.
FAQs
Calstock New Builds — local questions answered.
- What about utilities, drainage and access?
- All designed and applied for as part of the package — water, electric, off-mains drainage where mains isn't viable, and highways access agreement with Cornwall Council where required. In Calstock specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- What's a replacement dwelling and is mine eligible?
- If a habitable dwelling exists on the plot, you can often replace it — within volumetric and design constraints set by Cornwall's Local Plan. Derelict structures sometimes qualify, sometimes don't, depending on lawful use history.
- Can I build a new house on my plot in Cornwall?
- Sometimes yes, sometimes no — and the honest answer needs a planning policy review of the specific site. Settlement boundary, designations, access and policy on isolated dwellings all weigh in. We give a frank read at first consultation rather than a sales pitch.
