One studio for loft conversion in Polperro
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. Working in Polperro means starting from the PL13 context — Polperro is a famously photogenic East Cornwall fishing village with a tight Conservation Area covering the harbour, smugglers' cottages and the steep lanes inland — vehicle access is restricted in the village core, with a building stock that leans toward carefully detailed replacement dwellings and Victorian villas above the village.
Polperro sits in East Cornwall — covering PL13 from Looe outward.

Our process
How a Polperro 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.

Loft Conversions considerations specific to Polperro.
01
Cut-roof Cornish properties are easier to convert than modern trussed roofs; the structural strategy varies completely.
02
Stairs eat space — a loft conversion lives or dies by where the new staircase lands and what it costs you on the floor below.
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
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.
Local context
Why Polperro is its own job.
Two things shape a Polperro application: parish character and policy. On policy — conservation Area covers the entire harbour and historic core; AONB and Heritage Coast across the parish. Vehicle restrictions and tight access shape construction logistics on every project. For loft conversion specifically, parts of Polperro sit within a designated Conservation Area, which means materials, fenestration and roof pitches all need to read sympathetically with the existing streetscape; the surrounding landscape falls inside the Cornwall Area of Outstanding Natural Beauty, so massing, height and landscape impact carry extra weight in any planning decision; coastal salt-laden air around Polperro drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure; 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 Polperro programme tends to run on time. On carefully detailed replacement dwellings in particular — the kind you'll also find toward Looe — 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.

Polperro loft conversions — the local-studio difference.
Building stock
Across Polperro (PL13) we work on whitewashed cottages around the harbour, Victorian villas above the village, modern infill on the upper lanes, carefully detailed replacement dwellings. Each stock type drives a different loft conversion response — carefully detailed replacement dwellings in particular needs careful detailing here.
Parish & policy
Polperro is its own town in East Cornwall, with planning history that's specific to the PL13 catchment.

FAQs
Polperro 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 Polperro specifically, we'd start by checking the Conservation Area boundary 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.
- 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.
- 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.
