Loft Conversions for St Buryan (TR19)
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. St Buryan sits in Penwith, and that geography ends up in the drawings — St Buryan is an inland Penwith village with one of Cornwall's most substantial parish churches and a tight Conservation Area covering the churchyard and adjoining cottages, with a building stock that leans toward modern AONB-sensitive infill and Victorian rectory-style houses.
St Buryan sits in Penwith — just off the A30; covering TR19 from Sennen, Lamorna, Treen outward.

Page purpose
Drawings only, or drawings through to handover in St Buryan?
Both routes are open on a TR19 project, and the honest answer depends on whether you already have a builder you trust. Plenty of St Buryan 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 TR19 scope, not as one opaque figure

Who this is for
Straight facts about working with us here
- Applications for St Buryan are handled through Cornwall Council, with Truro the nearest planning office we deal with regularly.
- Designated-area work is routine here, so heritage and landscape statements are produced alongside the drawings rather than outsourced.
- Drawings, planning and building regulations are all produced in-house, so a loft conversion enquiry does not get passed between firms.
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.
What we focus on
Loft Conversions considerations specific to St Buryan.
01
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.
02
Cut-roof Cornish properties are easier to convert than modern trussed roofs; the structural strategy varies completely.
03
Stairs eat space — a loft conversion lives or dies by where the new staircase lands and what it costs you on the floor below.
04
Cornish slate roofs come in a huge range of pitches — anything below a 30° pitch struggles to give usable headroom without raising the ridge.

Local context
Why St Buryan is its own job.
In St Buryan the planning picture is specific: conservation Area covers the village core; AONB across the parish. The church (Grade I) and surrounding curtilage shape design considerations on most central sites. For loft conversion specifically, parts of St Buryan 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; 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. That local reading is what makes a St Buryan (TR19) project different from a generic Cornwall scheme — and is the whole reason we work this way. On modern AONB-sensitive infill in particular — the kind you'll also find toward Treen — the loft conversion brief always has to read the existing fabric first.
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.
Our process
How a St Buryan 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.
FAQs
St Buryan Loft Conversions — local questions answered.
- 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. In St Buryan specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- 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.
- 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.
- 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.
- 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.
- We live in the house. Can a loft conversion in St Buryan 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 St Buryan are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
