Renovations & Remodels in Charlestown
Cornish housing stock is brilliant and infuriating in equal measure. We renovate cottages, farmhouses, mid-century homes and post-war estates — opening up layouts, fixing damp, adding light and bringing the property up to a standard worth living in. The Charlestown version of this work has its own character — Charlestown is a Georgian-planned harbour village south of St Austell, World Heritage designated for its china clay shipping history, with tall ships still moored in the harbour, with a building stock that leans toward converted clay-shipping warehouses and Victorian villas.
Charlestown sits in South Cornwall — just off the A39; covering PL25 from St Austell, Carlyon Bay outward.

Who this is for
In Charlestown the renovation 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 Charlestown
These stages can be bought separately. Most PL25 projects use three of them.
Structural coordination
Calculations coordinated with the drawings so building control sees one consistent story.
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.
Who this is for
What we can genuinely back up in Charlestown
- Design and build are offered from the same studio, which means the person answering your Charlestown questions has seen the detail built.
- Drawings, planning and building regulations are all produced in-house, so a renovation 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 Charlestown
Charlestown is covered from our St Austell 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 Charlestown?
Both routes are open on a PL25 project, and the honest answer depends on whether you already have a builder you trust. Plenty of Charlestown 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 PL25 scope, not as one opaque figure
Local context
Why Charlestown is its own job.
Conservation Area covers the entire historic harbour; World Heritage Site status applies. The Charlestown Estate operates a strong design code on materials and layout. For renovation specifically, parts of Charlestown 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; coastal salt-laden air around Charlestown drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. So every Charlestown job runs as a PL25-specific piece of work — local policy, local fabric, local builders. Most of our renovation work in Charlestown lands on converted clay-shipping warehouses, with detailing that has to nod to the wider St Austell streetscape.
Planning note
Most Cornish renovations don't need planning — but listed status, curtilage listing, Conservation Area designation and material changes can all change that picture.
What we focus on
Renovations considerations specific to Charlestown.
01
Listed and curtilage-listed properties need Listed Building Consent for many internal alterations that wouldn't normally need approval.
02
Original fireplaces, slate floors, beams and joinery are often worth rescuing; the design conversation should start with what stays, not what goes.
03
Asbestos surveys are standard for anything pre-2000 — we factor a survey into the programme before stripping out begins.
04
Damp in Cornish cottages is usually a moisture management problem, not a chemical injection problem — fixing the cause is cheaper long term than treating the symptom.

FAQs
Charlestown Renovations — local questions answered.
- We live in the house. Can a renovation in Charlestown 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 Charlestown are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- Can I live in the house during the work?
- Sometimes yes, often no. Single-room remodels and phased work can be liveable; whole-house renovations involving rewires, replumbing or floor lifting almost never are. We're honest about this at the brief. In Charlestown specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- What about damp and old walls?
- We assess the cause first — usually rising damp myths, blocked vents, hard cement renders trapping moisture, or roofs needing attention. A breathable repair strategy fixes most of it without chemical intervention.
- How long does a renovation take?
- Single rooms in weeks, kitchens in two to three months, whole-house renovations in six to fourteen months depending on size and listed status.
- How much does a full renovation cost in Cornwall?
- A whole-house renovation typically lands between £1,800 and £3,000 per square metre depending on condition, listed status and finish level. We survey before quoting and don't price by guesswork.
Charlestown is part of St Austell
Charlestown sits inside the St Austell catchment — we cover both as one renovation territory.
See Renovations in St Austell →Local proof — We typically have one or two renovation jobs live in the PL25 area at any time, so the local planning officers know our drawings on sight.
