Design, planning and build for Praa Sands 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. What works on a TR20 plot rarely works elsewhere — Praa Sands is a south-coast surf beach village backed by dunes and low cliffs, mostly mid-twentieth-century holiday and family housing in the parishes of Breage and Germoe, with a building stock that leans toward modern coastal new builds and wooden cabins and chalets.
Praa Sands sits in West Cornwall, inside the TR20 postcode district.

Why Praa Sands is its own job.
Cornwall Council's lens on Praa Sands is consistent: aONB designation covers the whole village; coastal and dune-edge sites face strict material and ridge-height controls. Holiday-let and second-home pressure has shaped recent local plan policy. 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 Praa Sands drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. That's why we treat every Praa Sands project as a TR20-area job first — not a generic Cornwall job with a postcode bolted on. The modern coastal new builds that dominate Praa Sands (and continue out toward Porthleven) 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 Praa Sands.
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
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.

Praa Sands Loft Conversions — local questions answered.
- 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. In Praa Sands specifically, we'd start by checking AONB landscape sensitivity before committing to a direction.
- 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.
- 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.
