Loft Conversions that reads Pentewan properly
A well-designed loft conversion adds a bedroom, an en-suite and useful storage to homes that were never built with the upper floor in mind — usually inside permitted development and almost always cheaper per square metre than extending sideways. The Pentewan version of this work has its own character — Pentewan is an AONB former china clay shipping village south of St Austell, with a tight planned Conservation Area around the silted-up harbour and the holiday park inland, with a building stock that leans toward holiday park static caravans and Victorian villas.
Pentewan sits in South Cornwall — just off the B3273; with Truro the closest city; 0 miles from Pentewan, 5 miles from St Austell.

Our process
How a Pentewan loft conversion project runs.
Step 1
Feasibility
Roof, headroom, stair landing and structural assessment.
Step 2
Design
Layout options that respect the staircase, headroom and bathroom positioning.
Step 3
Approvals
Planning or permitted development confirmation, plus building regs.
Step 4
Build
Sequenced to keep the family living downstairs throughout most of the work.
Step 5
Handover
Finish, snag, certify, hand over the keys.
Loft conversions typically run six to eighteen weeks on site depending on type, with four to eight weeks of design and approvals beforehand.
Local proof — We typically have one or two loft conversion jobs live in the PL26 area at any time, so the local planning officers know our drawings on sight.

The parts of the job we can take on in Pentewan
Clients in Pentewan take different slices of this list, and that is deliberate.
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.
Heritage and design statements
Written justification where designation makes the design case as important as the drawing.
Who this is for
What we can genuinely back up in Pentewan
- Design and build are offered from the same studio, which means the person answering your Pentewan questions has seen the detail built.
- Commercial and mixed-use work in Pentewan tends to sit around Mevagissey Harbour.
- Drawings, planning and building regulations are all produced in-house, so a loft conversion 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 Pentewan
Pentewan works as a hub for us: the same loft conversion team covers Pentewan and the surrounding PL26 villages, so a site visit here often takes in more than one address.
Page purpose
Drawings only, or drawings through to handover in Pentewan?
Both routes are open on a PL26 project, and the honest answer depends on whether you already have a builder you trust. Plenty of Pentewan 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 PL26 scope, not as one opaque figure

What we focus on
Loft Conversions considerations specific to Pentewan.
01
Stairs eat space — a loft conversion lives or dies by where the new staircase lands and what it costs you on the floor below.
02
Cornish slate roofs come in a huge range of pitches — anything below a 30° pitch struggles to give usable headroom without raising the ridge.
03
Cut-roof Cornish properties are easier to convert than modern trussed roofs; the structural strategy varies completely.
04
Building regs require minimum 2.0 metre headroom over the stairs and 30-minute fire protection on the existing stair enclosure — both shape the design.
Local context
Why Pentewan is its own job.
Around Pentewan (PL26), conservation Area covers the harbour village; AONB across the parish. Former harbour silting and Pentewan Sands holiday park shape most local planning conversations. For loft conversion specifically, parts of Pentewan sit within a designated Conservation Area, which means materials, fenestration and roof pitches all need to read sympathetically with the existing streetscape; the surrounding landscape falls inside the Cornwall Area of Outstanding Natural Beauty, so massing, height and landscape impact carry extra weight in any planning decision; coastal salt-laden air around Pentewan drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure; Cornwall Council's Local Plan applies tighter tests to isolated rural dwellings here, so design rationale and policy fit need to be set out clearly from the outset. Reading Pentewan properly up front saves more time than any drawing tool ever will. Most of our loft conversion work in Pentewan lands on holiday park static caravans, with detailing that has to nod to the wider Pentewan streetscape.
Planning note
Most Cornish loft conversions are permitted development — but a Certificate of Lawfulness is worth the extra week and small fee for resale protection.

Pentewan is the hub for these neighbourhoods
We run loft conversions across Pentewan and the surrounding PL26 neighbourhoods — same studio, same site team.
- Pentewan
PL26
Local fabric
One PL26 studio, one loft conversion job — start to finish.
Building stock
Across Pentewan (PL26) we work on planned harbour cottages, Victorian villas, Edwardian houses, modern AONB-sensitive infill, holiday park static caravans. Each stock type drives a different loft conversion response — holiday park static caravans in particular needs careful detailing here.
Parish & policy
Pentewan sits in the parish of St Austell Bay, which matters for how parish-level consultation lands on a loft conversion application.
Coverage
We cover PL26 from our studio, with regular loft conversion jobs also running in Pentewan, St Austell, Gorran Haven. Most Pentewan site visits get booked within the same week.
Do you work in Pentewan regularly?
Yes — Pentewan and the wider PL26 catchment are core territory. We're typically on a South Cornwall site at least once a week, so logistics are baked in, not bolted on.

Pentewan runs the full mix — owner-occupier, holiday-let, commercial and the occasional smallholding — so we scope every loft conversion enquiry from the use-class up.
FAQs
Pentewan Loft Conversions — local questions answered.
- How much does a loft conversion cost?
- A simple Velux conversion starts around £30,000 in Cornwall; a rear dormer with en-suite typically runs £45,000 to £65,000; hip-to-gable and mansards more. Stair location and bathroom complexity drive most of the cost. In Pentewan specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- How long does a loft conversion take?
- Allow six to ten weeks on site for a Velux conversion, eight to fourteen weeks for a dormer, twelve to eighteen weeks for hip-to-gable. Add four to eight weeks for design and regs beforehand.
- Will it add value?
- An extra bedroom and bathroom typically adds noticeably more value than the build cost in most Cornish markets — but the value matters less than the daily use you'll get from the space.
- Who do you usually work for in Pentewan?
- A genuine mix: owner-occupiers, second-home and holiday-let owners, small commercial clients and the occasional smallholding. That matters because the right route for a loft conversion depends on how the property is used, not just what it looks like, so we scope from the use first.
- Do I need planning permission for a loft conversion?
- Often no — most loft conversions sit inside permitted development on a typical Cornish house. Conservation Areas, AONB and properties on principal elevations need full planning, and we'll confirm at first review.
- Will I have enough headroom?
- We need a minimum 2.2 metres ridge-to-joist before alterations to make a usable conversion straightforward. Less than that and we'd consider raising the ridge, which is a planning conversation, not a permitted development one.
