Loft Conversions for Cargreen (PL12)
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. Working in Cargreen means starting from the PL12 context — Cargreen is a creekside settlement in the PL12 area, with waterside homes, wooded valleys and narrow-lane access shaping the brief, with a building stock that leans toward creekside cottages and boat sheds.
Cargreen sits in East Cornwall — covering PL12 from Saltash, Hatt, Landrake outward.

Our process
How a Cargreen 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 proof — Our East Cornwall workload means a Cargreen loft conversion project never has to wait for an out-of-county team to drive down.

Loft Conversions considerations specific to Cargreen.
01
Cut-roof Cornish properties are easier to convert than modern trussed roofs; the structural strategy varies completely.
02
Stairs eat space — a loft conversion lives or dies by where the new staircase lands and what it costs you on the floor below.
03
Cornish slate roofs come in a huge range of pitches — anything below a 30° pitch struggles to give usable headroom without raising the ridge.
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.
Local context
Why Cargreen is its own job.
In Cargreen the planning picture is specific: creekside ecology, flood risk, trees and views across the water often matter as much as the building form itself. 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 Cargreen (PL12) project different from a generic Cornwall scheme — and is the whole reason we work this way. On creekside cottages in particular — the kind you'll also find toward Tideford — 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
Cargreen 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 Cargreen 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.
- 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.
