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 — just off the A39; covering PL30 from Bodmin, St Breward, Washaway outward.

Who this is for
In Warleggan 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.

Warleggan Loft Conversions — local questions answered.
- We live in the house. Can a loft conversion in Warleggan 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 Warleggan are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- 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.

For projects in Warleggan and the PL30 area.
Scope
What we can draw, survey and build around Warleggan
These stages can be bought separately. Most PL30 projects use three of them.
Structural coordination
Calculations coordinated with the drawings so building control sees one consistent story.
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.
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 Warleggan?
Both routes are open on a PL30 project, and the honest answer depends on whether you already have a builder you trust. Plenty of Warleggan 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 PL30 scope, not as one opaque figure

Warleggan is covered from our Bodmin 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
- Applications for Warleggan 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 Warleggan questions has seen the detail built.
- Drawings, planning and building regulations are all produced in-house, so a loft conversion enquiry does not get passed between firms.
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 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. Where a property sits inside a conservation area or is listed, the assessment tends to turn on materials, window detailing and how visible the change is from the street rather than floor area alone. Cornwall Council's conservation team, or the Planning Portal, is the right place to confirm what applies to a specific address. Granite and cob walls do not behave like modern cavity construction. Breathability, damp movement and structural openings all need drawing properly, and building control will want that shown rather than assumed.
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.
