One studio for loft conversion in Mount
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. Mount sits in North Cornwall, and that geography ends up in the drawings — Mount 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 isolated houses and small rural infill.
Mount sits in North Cornwall — just off the A39; covering PL30 from Bodmin, St Breward, Washaway outward.

Page purpose
Drawings only, or drawings through to handover in Mount?
Both routes are open on a PL30 project, and the honest answer depends on whether you already have a builder you trust. Plenty of Mount 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
Scope
Scope options for Mount clients
These stages can be bought separately. Most PL30 projects use three of them.
Building regulation drawings
Full Plans sets with sections, construction notes and coordinated structural information.
Measured survey
An accurate record of what is actually there, which is where most avoidable cost is removed.
Construction and technical drawings
1:10 and 1:20 details for the parts of the job builders normally have to guess at.
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.
Local watch-list
Local snags worth knowing before drawing a Mount loft conversion.
Watch #1
Local Plan tests on isolated dwellings, plus lane access for plant and deliveries around Mount
Watch #2
Party Wall notices and shallow roof voids typical of stone cottages in the PL30 district

- Applications for Mount are handled through Cornwall Council, with Bodmin the nearest planning office we deal with regularly.
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.
What we focus on
Loft Conversions considerations specific to Mount.
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
Cut-roof Cornish properties are easier to convert than modern trussed roofs; the structural strategy varies completely.
03
Stairs eat space — a loft conversion lives or dies by where the new staircase lands and what it costs you on the floor below.
04
Cornish slate roofs come in a huge range of pitches — anything below a 30° pitch struggles to give usable headroom without raising the ridge.

Local context
Why Mount is its own job.
Two things shape a Mount application: parish character and policy. On policy — 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. Get that local reading right and the rest of the Mount programme tends to run on time. On isolated houses in particular — the kind you'll also find toward Nanstallon — the loft conversion brief always has to read the existing fabric first.
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.

FAQs
Mount Loft Conversions — local questions answered.
- 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. In Mount specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- We live in the house. Can a loft conversion in Mount 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 Mount are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- 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.
- 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.
- 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.
- 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.
Mount is part of Bodmin
Mount sits inside the Bodmin catchment — we cover both as one loft conversion territory.

Where to go next from Mount
Mount 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.

Nearby places we cover
Most Mount loft conversion enquiries start with one honest conversation about what's actually allowed — and that conversation costs nothing. Lane access and rural policy tests shape what is realistic on an isolated plot.
