Warleggan 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. In Warleggan, that work is shaped by the place itself — Warleggan is a moorland-edge hamlet in the PL30 area, where exposed weather, narrow lanes and rural character set the brief, with a building stock that leans toward small rural infill and isolated houses.
Warleggan sits in North Cornwall — covering PL30 from Bodmin, St Breward, Washaway outward.

Warleggan 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 Warleggan specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- 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.
- 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 Warleggan is its own job.
Locally, rural policy, landscape impact and services such as drainage are usually the key constraints, especially outside settlement boundaries. 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 Warleggan projects parish-up, not template-down — the PL30 context shapes the design from day one. Whether the project is on small rural infill in the centre or further out toward Bodmin, 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 Warleggan.
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.

How a Warleggan loft conversion project runs.
Step 1

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.

Why a North Cornwall studio is the right fit for Warleggan loft conversion.
Building stock
Across Warleggan (PL30) we work on stone cottages, farm buildings, isolated houses, converted barns, small rural infill. Each stock type drives a different loft conversion response — small rural infill in particular needs careful detailing here.
Parish & policy
Warleggan sits in the parish of Warleggan, 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 Bodmin, St Breward, Washaway. Most Warleggan site visits get booked within the same week.
What does a first Warleggan 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.
