Loft Conversions for Cardinham (PL30)
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. The way we approach loft conversion in Cardinham starts with a measured walk-round — Cardinham is a moorland-edge hamlet in the PL30 area, where exposed weather, narrow lanes and rural character set the brief, with a building stock that leans toward stone cottages and isolated houses.
Cardinham sits in North Cornwall — covering PL30 from Bodmin, St Breward, Washaway outward.

Loft Conversions considerations specific to Cardinham.
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
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.
Local context
Why Cardinham is its own job.
In Cardinham the planning picture is specific: rural policy, landscape impact and services such as drainage are usually the key constraints, especially outside settlement boundaries. For loft conversion specifically, 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. That local reading is what makes a Cardinham (PL30) project different from a generic Cornwall scheme — and is the whole reason we work this way. On stone cottages in particular — the kind you'll also find toward Nanstallon — the loft conversion brief always has to read the existing fabric first.
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.

FAQs
Cardinham Loft Conversions — local questions answered.
- 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. In Cardinham specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- 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.
- 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.
