Loft conversion timeline in Polzeath — week by week
From first site visit to occupation, a Polzeath loft conversion runs around 18–28 weeks. The variability sits in two places: whether planning is needed at all (most PL27 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. The way we approach loft conversion in Polzeath starts with a measured walk-round — Polzeath is the surfing village above one of north Cornwall's biggest sandy beaches, AONB-designated, with a holiday-let-heavy housing stock and increasing replacement-dwelling activity, with a building stock that leans toward high-end replacement dwellings and 1960s bungalows above the beach.
Polzeath sits in North Cornwall — covering PL27 from Rock, Trebetherick, St Minver outward.

Who this is for
Polzeath 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 Polzeath is its own job.
Two things shape a Polzeath application: parish character and policy. On policy — aONB and Heritage Coast designations across the village; cliff and dune-edge sites are tightly controlled. Local plan policy on second homes and holiday lets is being progressively tightened. For loft conversion specifically, 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 Polzeath 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 Polzeath programme tends to run on time. On high-end replacement dwellings in particular — the kind you'll also find toward Padstow — 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 Polzeath.
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 Polzeath 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

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
Polzeath Loft Conversions — local questions answered.
- Do I need planning permission for a loft conversion in Polzeath?
- Usually no — most PL27 lofts qualify under permitted development. Article 4 catches a handful of streets, which we check first. Velux conversions are nearly always PD; full dormers sometimes need a Lawful Development Certificate.
- How long is the on-site build for a Polzeath 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 Polzeath 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 Polzeath specifically, we'd start by checking AONB landscape sensitivity 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.
