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 — covering PL27 from Padstow, Trevone, Harlyn outward.

Who this is for
St Eval 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.

What usually catches loft conversion projects out in St Eval.
Watch #1
Tighter Local Plan tests on isolated rural dwellings
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.
- 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.
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.
Our process
How a St Eval 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
Choosing a loft conversion team that actually knows PL27.
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.
