Crowan 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. In Crowan, that work is shaped by the place itself — Crowan is a rural parish in the TR14 area, with farmsteads, lanes and scattered homes defining its built character, with a building stock that leans toward farmhouses and converted barns.
Crowan sits in Mid Cornwall — covering TR14 from Camborne, Praze-an-Beeble, Truro outward.

Who this is for
Crowan 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 proof — Most Crowan loft conversion clients we work with are second-time builders — they've seen the templated approach fail once already.

Crowan Loft Conversions — local questions answered.
- 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. In Crowan 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 Crowan is its own job.
The planning backdrop in Mid 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, the wider area forms part of the Cornish Mining World Heritage Site, which adds a heritage assessment layer to most material changes; 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 TR14 parish brief as the design brief and the Crowan application has somewhere to land. Whether the project is on farmhouses in the centre or further out toward Camborne, 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 Crowan.
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
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.
03
Cut-roof Cornish properties are easier to convert than modern trussed roofs; the structural strategy varies completely.
04
Stairs eat space — a loft conversion lives or dies by where the new staircase lands and what it costs you on the floor below.
Our process
How a Crowan 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 a Mid Cornwall studio is the right fit for Crowan loft conversion.
Building stock
Across Crowan (TR14) we work on farmhouses, converted barns, rural cottages, smallholdings, scattered modern homes. Each stock type drives a different loft conversion response — farmhouses in particular needs careful detailing here.
Parish & policy
Crowan sits in the parish of Crowan, which matters for how parish-level consultation lands on a loft conversion application.
Coverage
We cover TR14 from our studio, with regular loft conversion jobs also running in Camborne, Praze-an-Beeble, Truro. Most Crowan site visits get booked within the same week.
What does a first Crowan consultation cost?
Nothing. We come to the property, walk the site, talk through what works on a TR14 plot and follow up with a written feasibility note inside a week — no obligation either way.
