Loft conversion timeline in Looe — week by week
From first site visit to occupation, a Looe loft conversion runs around 18–28 weeks. The variability sits in two places: whether planning is needed at all (most PL13 lofts are PD) and how complex the structural design is for the existing roof. We map both at feasibility stage. 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 Looe means starting from the PL13 context — Looe is a working fishing town and seaside resort split by the Looe River into East and West Looe, with one of Cornwall's largest fishing fleets and a substantial Conservation Area covering both halves, with a building stock that leans toward modern coastal homes at Hannafore and Victorian guesthouses.
Looe sits in East Cornwall — covering PL13 from Polperro, Duloe, Talland outward.

Who this is for
Looe runs the full mix — owner-occupier, holiday-let, commercial and the occasional smallholding — so we scope every loft conversion enquiry from the use-class up.
Local context
Why Looe is its own job.
Two things shape a Looe application: parish character and policy. On policy — conservation Area covers both East and West Looe historic cores; AONB across the wider parish. Flood Zone 3 designation affects substantial parts of the harbour and town. For loft conversion specifically, parts of Looe 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 Looe drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. Get that local reading right and the rest of the Looe programme tends to run on time. On modern coastal homes at Hannafore in particular — the kind you'll also find toward Morval — 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.
What we focus on
Loft Conversions considerations specific to Looe.
01
Stairs eat space — a loft conversion lives or dies by where the new staircase lands and what it costs you on the floor below.
02
Cornish slate roofs come in a huge range of pitches — anything below a 30° pitch struggles to give usable headroom without raising the ridge.
03
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.
04
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.
Our process
How a Looe 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.
FAQs
Looe Loft Conversions — local questions answered.
- Do I need planning permission for a loft conversion in Looe?
- Usually no — most PL13 lofts qualify under permitted development. Conservation Area restrictions remove some PD rights here. Velux conversions are nearly always PD; full dormers sometimes need a Lawful Development Certificate.
- How long is the on-site build for a Looe loft conversion?
- 8–12 weeks on site, depending on stair access and whether you're staying in the property. Steel install and weather-tight enclosure happen in weeks 2–4; first fix and finishes fill the rest.
- Can the loft conversion run while we're living in the house?
- Yes — most Looe clients stay in. Dust protection at the existing landing is the main consideration. Bathroom commissioning is the only week you'll really notice.
- 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 Looe specifically, we'd start by checking the Conservation Area boundary 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.
