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 — covering PL30 from Bodmin, St Breward, Washaway outward.

Our process
How a Mount 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 proof — Most Mount loft conversion clients we work with are second-time builders — they've seen the templated approach fail once already.

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.

Tighter Local Plan tests on isolated rural dwellings
Mount is part of Bodmin
Mount sits inside the Bodmin catchment — we cover both as one loft conversion territory.

One PL30 studio, one loft conversion job — start to finish.
Building stock
Across Mount (PL30) we work on stone cottages, farm buildings, isolated houses, converted barns, small rural infill. Each stock type drives a different loft conversion response — isolated houses in particular needs careful detailing here.
Parish & policy
Mount sits in the parish of Mount, 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 Mount site visits get booked within the same week.

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.
- 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.
