The Lizard loft conversions — a Lizard Peninsula studio
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. Anchor any The Lizard loft conversion in the local fabric and the rest follows — The Lizard is the southernmost village in mainland Britain, sitting on the AONB headland with serpentine geology, a working lighthouse and a tight Conservation Area at the village green, with a building stock that leans toward serpentine-stone cottages and modern carefully detailed coastal homes.
The Lizard sits in Lizard Peninsula — covering TR12 from Mullion outward.

The Lizard 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 The Lizard specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- Can I live downstairs while it's built?
- Yes — most loft conversions are built with the family staying in the house. There'll be a couple of disruptive days when the staircase comes through, but the bulk of the work is upstairs.
- 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.
- 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.
Local context
Why The Lizard is its own job.
The planning backdrop in Lizard Peninsula is real, not abstract: conservation Area, AONB and Heritage Coast all apply; coastal cliff exposure and views from the South West Coast Path are weighed heavily. Serpentine quarrying heritage adds a further design layer. For loft conversion specifically, parts of The Lizard 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 The Lizard 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. Treat the TR12 parish brief as the design brief and the The Lizard application has somewhere to land. Whether the project is on serpentine-stone cottages in the centre or further out toward Mullion, 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 The Lizard.
01
Cut-roof Cornish properties are easier to convert than modern trussed roofs; the structural strategy varies completely.
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 The Lizard 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 a Lizard Peninsula studio is the right fit for The Lizard loft conversion.
Building stock
Across The Lizard (TR12) we work on serpentine-stone cottages, Edwardian villas, 1950s coastal bungalows, modern carefully detailed coastal homes. Each stock type drives a different loft conversion response — serpentine-stone cottages in particular needs careful detailing here.
Parish & policy
The Lizard sits in the parish of Landewednack, which matters for how parish-level consultation lands on a loft conversion application.
Coverage
We cover TR12 from our studio, with regular loft conversion jobs also running in Mullion, Coverack. Most The Lizard site visits get booked within the same week.
What does a first The Lizard consultation cost?
Nothing. We come to the property, walk the site, talk through what works on a TR12 plot and follow up with a written feasibility note inside a week — no obligation either way.
