St Teath loft conversions — a North 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. In St Teath, that work is shaped by the place itself — St Teath is a rural parish in the PL30 area, with farmsteads, lanes and scattered homes defining its built character, with a building stock that leans toward scattered modern homes and farmhouses.
St Teath sits in North Cornwall — covering PL30 from Camelford, Davidstow, Advent outward.

Who this is for
St Teath 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.

St Teath 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 Teath specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- 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.
- 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 Teath is its own job.
The planning backdrop in North Cornwall is real, not abstract: open-countryside policy, access lanes, drainage and agricultural building history all need to be addressed before drawings go too far. 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 PL30 parish brief as the design brief and the St Teath application has somewhere to land. Whether the project is on scattered modern homes in the centre or further out toward Camelford, 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 Teath.
01
Cut-roof Cornish properties are easier to convert than modern trussed roofs; the structural strategy varies completely.
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
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.
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.

Building stock
Across St Teath (PL30) we work on farmhouses, converted barns, rural cottages, smallholdings, scattered modern homes. Each stock type drives a different loft conversion response — scattered modern homes in particular needs careful detailing here.
Parish & policy
St Teath sits in the parish of St Teath, which matters for how parish-level consultation lands on a loft conversion application.
Coverage
We cover PL30 from our studio, with regular loft conversion jobs also running in Camelford, Davidstow, Advent. Most St Teath site visits get booked within the same week.
What does a first St Teath consultation cost?
Nothing. We come to the property, walk the site, talk through what works on a PL30 plot and follow up with a written feasibility note inside a week — no obligation either way.
