St Eval loft conversion — feasibility first, drawings second
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 St Eval site, the brief always meets the place — St Eval is an estate-influenced village in the PL27 area, with designed landscape, older cottages and rural edges close together, with a building stock that leans toward estate cottages and converted outbuildings.
St Eval sits in North Cornwall — just off the A39; covering PL27 from Padstow, Trevone, Harlyn outward.

Who this is for
In St Eval the loft conversion brief is almost always a private homeowner improving a forever home — so we lead with feasibility and long-term value, not show-home rhetoric.
Local watch-list
What usually catches loft conversion projects out in St Eval.
Watch #1
Local Plan tests on isolated dwellings, plus lane access for plant and deliveries around St Eval
Watch #2
Party Wall notices and shallow roof voids typical of estate cottages in the PL27 district
Watch #3
Trussed roofs and shallow foundations in the later PL27 estates, which change the structural strategy
Local proof — Most St Eval homeowners come to us after a loft conversion quote elsewhere felt vague on planning — we lead with feasibility instead.

St Eval Loft Conversions — local questions answered.
- We live in the house. Can a loft conversion in St Eval 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 Eval 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 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. In St Eval specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- 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.
- 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.
- 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.

Scope
What we can draw, survey and build around St Eval
Not every project needs every stage. On a St Eval job we scope to what the site and the consent route actually require.
Planning application drawings
Existing and proposed plans, elevations, site and block plans drawn to validation standard.
Construction and technical drawings
1:10 and 1:20 details for the parts of the job builders normally have to guess at.
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.
Building regulation drawings
Full Plans sets with sections, construction notes and coordinated structural information.
Page purpose
Drawings only, or drawings through to handover in St Eval?
Both routes are open on a PL27 project, and the honest answer depends on whether you already have a builder you trust. Plenty of St Eval 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 PL27 scope, not as one opaque figure

Follow the chain: survey, drawings, build
St Eval is covered from our Padstow 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.
Who this is for
Why this page exists, and who it is for
- Drawings, planning and building regulations are all produced in-house, so a loft conversion enquiry does not get passed between firms.
- Applications for St Eval are handled through Cornwall Council, with Bodmin the nearest planning office we deal with regularly.
- Design and build are offered from the same studio, which means the person answering your St Eval questions has seen the detail built.
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.
Local context
Why St Eval is its own job.
Locally, landscape setting, curtilage history and estate character need a precise design rationale rather than a standard suburban approach. 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. Which is why we scope St Eval projects parish-up, not template-down — the PL27 context shapes the design from day one. Whether the project is on estate cottages in the centre or further out toward Padstow, 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 St Eval.
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
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.
03
Cornish slate roofs come in a huge range of pitches — anything below a 30° pitch struggles to give usable headroom without raising the ridge.
04
Cut-roof Cornish properties are easier to convert than modern trussed roofs; the structural strategy varies completely.

Building stock
Across St Eval (PL27) we work on estate cottages, farm buildings, detached homes, converted outbuildings, small infill plots. Each stock type drives a different loft conversion response — estate cottages in particular needs careful detailing here.
Parish & policy
St Eval sits in the parish of St Eval, which matters for how parish-level consultation lands on a loft conversion application.
Coverage
We cover PL27 from our studio, with regular loft conversion jobs also running in Padstow, Trevone, Harlyn. Most St Eval site visits get booked within the same week.
What does a first St Eval consultation cost?
Nothing. We come to the property, walk the site, talk through what works on a PL27 plot and follow up with a written feasibility note inside a week — no obligation either way.

St Eval sits inside the Padstow catchment — we cover both as one loft conversion territory.

Whichever route suits your PL27 project, the survey and feasibility work is the same, so nothing is wasted. Lane access and rural policy tests shape what is realistic on an isolated plot.
