One studio for loft conversion in Polzeath
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 — just off the A39; covering PL27 from Rock, Trebetherick, St Minver outward.

Page purpose
Drawings only, or drawings through to handover in Polzeath?
Both routes are open on a PL27 project, and the honest answer depends on whether you already have a builder you trust. Plenty of Polzeath clients take the drawings, tender them locally, then come back to us for the build if the numbers do not stack up.
- Route one: feasibility, planning and a tender-ready technical pack
- Route two: the same pack, then the build under one contract
- Either way the survey and feasibility work is identical, so the decision can wait
- Fees quoted per stage against the PL27 scope, not as one opaque figure

One contract from first sketch to handover, with the same team on paper and on site.
Construction and technical drawings
1:10 and 1:20 details for the parts of the job builders normally have to guess at.
Building regulation drawings
Full Plans sets with sections, construction notes and coordinated structural information.
Measured survey
An accurate record of what is actually there, which is where most avoidable cost is removed.
Heritage and design statements
Written justification where designation makes the design case as important as the drawing.
Local watch-list
What usually catches loft conversion projects out in Polzeath.
Watch #1
AONB landscape-impact testing on anything read in long views across North Cornwall
Watch #2
Exposure detailing on 1930s coastal villas — fixings, render systems and joinery specified for salt-laden air
Watch #3
Local Plan tests on isolated dwellings, plus lane access for plant and deliveries around Polzeath
Watch #4
Trussed roofs and shallow foundations in the later PL27 estates, which change the structural strategy
Who this is for
Straight facts about working with us here
- Applications for Polzeath are handled through Cornwall Council, with Bodmin the nearest planning office we deal with regularly.
- Designated-area work is routine here, so heritage and landscape statements are produced alongside the drawings rather than outsourced.
- Drawings, planning and building regulations are all produced in-house, so a loft conversion enquiry does not get passed between firms.
Planning rules change and every site is different. For the final position on your address, check with Cornwall Council as the local planning authority or the Planning Portal.
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.

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. Coastal sites tend to raise questions about roof form, glazing exposure and how a scheme reads from public viewpoints. Those are policy judgements rather than fixed rules, so the local planning authority or the Planning Portal should confirm the position for a given plot. Rural and moorland plots bring access, drainage and landscape impact into the conversation early. Agricultural conversions in particular follow their own route, and whether a building qualifies is a question for the local planning authority rather than a general rule.
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.

FAQs
Polzeath 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 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.
- We live in the house. Can a loft conversion in Polzeath be done while we stay put?
- Usually yes for single-storey and rear work, with a temporary kitchen or bathroom arrangement agreed before the start. Whole-house remodels and roof work in Polzeath are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- 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.

Designing a loft conversion in Polzeath is as much about reading the parish as reading the brief; we do both, and the planning outcomes follow. Parish-level consultation in St Minver is worth planning for, not reacting to.
