Tregorrick loft conversions — a Mid Cornwall studio
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. On a Tregorrick site, the brief always meets the place — Tregorrick is a town-edge neighbourhood in the PL26 area, where modern housing, larger gardens and edge-of-settlement plots create practical development opportunities, with a building stock that leans toward detached houses and infill plots.
Tregorrick sits in Mid Cornwall — covering PL26 from St Austell, Bugle, St Dennis outward.

Who this is for
Tregorrick 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.
Local watch-list
Local snags worth knowing before drawing a Tregorrick loft conversion.
Watch #1
Tighter Local Plan tests on isolated rural dwellings
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.

Tregorrick Loft Conversions — local questions answered.
- 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. In Tregorrick specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- Can I live downstairs while it's built?
- Yes — most loft conversions are built with the family staying in the house. There'll be a couple of disruptive days when the staircase comes through, but the bulk of the work is upstairs.
- 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 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.
- 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.
Local context
Why Tregorrick is its own job.
The planning backdrop in Mid Cornwall is real, not abstract: neighbour amenity, highways, drainage and the transition from built-up edge to countryside are usually the planning pressure points. For loft conversion specifically, 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. Treat the PL26 parish brief as the design brief and the Tregorrick application has somewhere to land. Whether the project is on detached houses in the centre or further out toward St Austell, the loft conversion response is locally tuned.
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.
What we focus on
Loft Conversions considerations specific to Tregorrick.
01
Permitted development volume allowances are 40 cubic metres on a terrace and 50 on a detached or semi — but rear dormers in Conservation Areas often need full planning.
02
Stairs eat space — a loft conversion lives or dies by where the new staircase lands and what it costs you on the floor below.
03
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.
04
Cut-roof Cornish properties are easier to convert than modern trussed roofs; the structural strategy varies completely.
Our process
How a Tregorrick 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 fabric
Why Tregorrick homeowners pick a local studio for loft conversion.
Building stock
Across Tregorrick (PL26) we work on modern estates, bungalows, semis, detached houses, infill plots. Each stock type drives a different loft conversion response — detached houses in particular needs careful detailing here.
Parish & policy
Tregorrick sits in the parish of Tregorrick, 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 St Austell, Bugle, St Dennis. Most Tregorrick site visits get booked within the same week.
What does a first Tregorrick consultation cost?
Nothing. We come to the property, walk the site, talk through what works on a PL26 plot and follow up with a written feasibility note inside a week — no obligation either way.

Tregorrick sits inside the St Austell catchment — we cover both as one loft conversion territory.
