Design, planning and build for Drakewalls 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 PL18 plot rarely works elsewhere — Drakewalls is a former mining settlement in the PL18 area, with granite terraces, chapel buildings and industrial landscape character still visible, with a building stock that leans toward miners cottages and post-war estates.
Drakewalls sits in East Cornwall — covering PL18 from Callington, Stoke Climsland, Linkinhorne outward.

Why Drakewalls is its own job.
Cornwall Council's lens on Drakewalls is consistent: mining heritage, old plot widths and traditional materials make proportion and detailing more important than generic extension templates. For loft conversion specifically, the wider area forms part of the Cornish Mining World Heritage Site, which adds a heritage assessment layer to most material changes. That's why we treat every Drakewalls project as a PL18-area job first — not a generic Cornwall job with a postcode bolted on. The miners cottages that dominate Drakewalls (and continue out toward Linkinhorne) 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 Drakewalls.
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
Cut-roof Cornish properties are easier to convert than modern trussed roofs; the structural strategy varies completely.
03
Stairs eat space — a loft conversion lives or dies by where the new staircase lands and what it costs you on the floor below.
04
Cornish slate roofs come in a huge range of pitches — anything below a 30° pitch struggles to give usable headroom without raising the ridge.

Drakewalls 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 Drakewalls specifically, we'd start by checking the latest parish-level planning history 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 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.
