Design, planning and build for Lelant loft conversion
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. A TR26 site visit comes before a Lelant sketch, every time — Lelant is the AONB estuary village south of St Ives, with a Norman church on the dunes, the West Cornwall Golf Club and one of the most stable period property markets in West Cornwall, with a building stock that leans toward Victorian terraces and 1930s detached houses.
Lelant sits in West Cornwall — covering TR26 from Carbis Bay, St Ives, Hayle outward.

Why Lelant is its own job.
Cornwall Council's lens on Lelant is consistent: conservation Area covers the village core and church; AONB across the parish. Estuary views and the Hayle estuary SSSI shape applications on the eastern edge of the village. For loft conversion specifically, parts of Lelant 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 Lelant drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. That's why we treat every Lelant project as a TR26-area job first — not a generic Cornwall job with a postcode bolted on. The Victorian terraces that dominate Lelant (and continue out toward Carbis Bay) set the tone for any loft conversion scheme here.
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 Lelant.
01
Cornish slate roofs come in a huge range of pitches — anything below a 30° pitch struggles to give usable headroom without raising the ridge.
02
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.
03
Cut-roof Cornish properties are easier to convert than modern trussed roofs; the structural strategy varies completely.
04
Stairs eat space — a loft conversion lives or dies by where the new staircase lands and what it costs you on the floor below.
Our process
How a Lelant 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 West Cornwall studio is the right fit for Lelant loft conversion.
Building stock
Across Lelant (TR26) we work on Edwardian villas above the estuary, 1930s detached houses, Victorian terraces, modern carefully detailed coastal replacements. Each stock type drives a different loft conversion response — Victorian terraces in particular needs careful detailing here.
Parish & policy
Lelant sits in the parish of St Ives, which matters for how parish-level consultation lands on a loft conversion application.

Lelant Loft Conversions — local questions answered.
- 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. In Lelant 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.
- 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.
- 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.
Lelant is part of Carbis Bay
Lelant sits inside the Carbis Bay catchment — we cover both as one loft conversion territory.
