Gorran Haven loft conversion — feasibility first, drawings second
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. On a Gorran Haven site, the brief always meets the place — Gorran Haven is an AONB south coast cove village south of Mevagissey, with a tight Conservation Area at the harbour and a network of cliff paths to Dodman Point, with a building stock that leans toward traditional harbour cottages and modern carefully detailed coastal homes.
Gorran Haven sits in South Cornwall — just off the A39; covering PL26 from Pentewan outward.

Gorran Haven Loft Conversions — local questions answered.
- 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. In Gorran Haven 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.
- 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 Gorran Haven 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 Gorran Haven are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- 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.

Who this is for
Why this page exists, and who it is for
- Drawings, planning and building regulations are all produced in-house, so a loft conversion enquiry does not get passed between firms.
- Designated-area work is routine here, so heritage and landscape statements are produced alongside the drawings rather than outsourced.
- Applications for Gorran Haven are handled through Cornwall Council, with Truro the nearest planning office we deal with regularly.
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.

Follow the chain: survey, drawings, build
We cover Gorran Haven and the wider PL26 district directly. Loft Conversions enquiries here are common enough that we know the constraints before the first visit.
Page purpose
Drawings only, or drawings through to handover in Gorran Haven?
Both routes are open on a PL26 project, and the honest answer depends on whether you already have a builder you trust. Plenty of Gorran Haven 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 PL26 scope, not as one opaque figure

Local context
Why Gorran Haven is its own job.
Locally, conservation Area covers the harbour village; AONB and Heritage Coast across the parish. Coastal margin and cliff sites face strict controls; Dodman Point conservation considerations apply nearby. For loft conversion specifically, parts of Gorran Haven 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 Gorran Haven 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. Which is why we scope Gorran Haven projects parish-up, not template-down — the PL26 context shapes the design from day one. Whether the project is on traditional harbour cottages in the centre or further out toward Pentewan, the loft conversion response is locally tuned. Where a property sits inside a conservation area or is listed, the assessment tends to turn on materials, window detailing and how visible the change is from the street rather than floor area alone. Cornwall Council's conservation team, or the Planning Portal, is the right place to confirm what applies to a specific address. 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.
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 Gorran Haven.
01
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.
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
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.
04
Cut-roof Cornish properties are easier to convert than modern trussed roofs; the structural strategy varies completely.
