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 — just off the A38; covering PL18 from Callington, Stoke Climsland, Linkinhorne outward.

Local watch-list
Common Calstock pitfalls we plan around.
Watch #1
Conservation Area controls on materials, window proportions and roof form through central Calstock
Watch #2
World Heritage Site heritage assessment where changes are visible in the mining landscape
Watch #3
Party Wall notices and shallow roof voids typical of creekside cottages in the PL18 district
Who this is for
In Calstock the new build brief is almost always a private homeowner improving a forever home — so we lead with feasibility and long-term value, not show-home rhetoric.
Scope
The parts of the job we can take on in Calstock
These stages can be bought separately. Most PL18 projects use three of them.
Full design and build
One contract from first sketch to handover, with the same team on paper and on site.
Construction and technical drawings
1:10 and 1:20 details for the parts of the job builders normally have to guess at.
Building regulation drawings
Full Plans sets with sections, construction notes and coordinated structural information.
Planning application drawings
Existing and proposed plans, elevations, site and block plans drawn to validation standard.
Measured survey
An accurate record of what is actually there, which is where most avoidable cost is removed.
Who this is for
What we can genuinely back up in Calstock
- Design and build are offered from the same studio, which means the person answering your Calstock questions has seen the detail built.
- Drawings, planning and building regulations are all produced in-house, so a new build enquiry does not get passed between firms.
- Designated-area work is routine here, so heritage and landscape statements are produced alongside the drawings rather than outsourced.
Planning rules change and every site is different. For the final position on your address, check with Cornwall Council as the local planning authority or the Planning Portal.

Other work we do around Calstock
Calstock is covered from our Callington run. Being a smaller place, the local detail matters more than the headline policy: lane access, neighbour proximity and what the immediate street already looks like.
Page purpose
Drawings only, or drawings through to handover in Calstock?
Both routes are open on a PL18 project, and the honest answer depends on whether you already have a builder you trust. Plenty of Calstock clients take the drawings, tender them locally, then come back to us for the build if the numbers do not stack up.
- Route one: feasibility, planning and a tender-ready technical pack
- Route two: the same pack, then the build under one contract
- Either way the survey and feasibility work is identical, so the decision can wait
- Fees quoted per stage against the PL18 scope, not as one opaque figure
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.
- We live in the house. Can a new build in Calstock be done while we stay put?
- Usually yes for single-storey and rear work, with a temporary kitchen or bathroom arrangement agreed before the start. Whole-house remodels and roof work in Calstock are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- 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.
Calstock is part of Callington
Calstock sits inside the Callington catchment — we cover both as one new build territory.
