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 — covering PL26 from Mevagissey 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.
- 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.
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 Mevagissey, the loft conversion response is locally tuned.
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.
Our process
How a Gorran Haven 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.
Local fabric
Why Gorran Haven homeowners pick a local studio for loft conversion.
Building stock
Across Gorran Haven (PL26) we work on traditional harbour cottages, Victorian villas, Edwardian houses above the cove, modern carefully detailed coastal homes. Each stock type drives a different loft conversion response — traditional harbour cottages in particular needs careful detailing here.
Parish & policy
Gorran Haven sits in the parish of Gorran, which matters for how parish-level consultation lands on a loft conversion application.
Coverage
We cover PL26 from our studio, with regular loft conversion jobs also running in Mevagissey. Most Gorran Haven site visits get booked within the same week.
What does a first Gorran Haven consultation cost?
Nothing. We come to the property, walk the site, talk through what works on a PL26 plot and follow up with a written feasibility note inside a week — no obligation either way.
