One studio for loft conversion in Lanreath
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. Lanreath sits in East Cornwall, and that geography ends up in the drawings — Lanreath is a rural parish in the PL13 area, with farmsteads, lanes and scattered homes defining its built character, with a building stock that leans toward farmhouses and rural cottages.
Lanreath sits in East Cornwall — covering PL13 from Looe, Duloe, Herodsfoot outward.

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

Loft Conversions considerations specific to Lanreath.
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 Lanreath is its own job.
Two things shape a Lanreath application: parish character and policy. On policy — open-countryside policy, access lanes, drainage and agricultural building history all need to be addressed before drawings go too far. 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 Lanreath programme tends to run on time. On farmhouses in particular — the kind you'll also find toward Pelynt — 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.

Lanreath is part of Looe
Lanreath sits inside the Looe catchment — we cover both as one loft conversion territory.

What sets a Lanreath loft conversion brief apart.
Building stock
Across Lanreath (PL13) 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
Lanreath sits in the parish of Lanreath, which matters for how parish-level consultation lands on a loft conversion application.

FAQs
Lanreath Loft Conversions — local questions answered.
- 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. In Lanreath specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- 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.
- 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.
- 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.
