Design, planning and build for Fraddon 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 TR9 plot rarely works elsewhere — Fraddon is a commuter village in the TR9 area, with everyday family housing, edge-of-village plots and quick routes to its parent town, with a building stock that leans toward garden infill plots and older cottages.
Fraddon sits in Mid Cornwall — just off the A390; covering TR9 from St Columb Major, Talskiddy, Truro outward.

Why Fraddon is its own job.
Cornwall Council's lens on Fraddon is consistent: applications here usually turn on neighbour amenity, parking, overlooking and whether new work fits the rhythm of existing streets. 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's why we treat every Fraddon project as a TR9-area job first — not a generic Cornwall job with a postcode bolted on. The garden infill plots that dominate Fraddon (and continue out toward Truro) 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 Fraddon.
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.
Page purpose
Drawings only, or drawings through to handover in Fraddon?
Both routes are open on a TR9 project, and the honest answer depends on whether you already have a builder you trust. Plenty of Fraddon clients take the drawings, tender them locally, then come back to us for the build if the numbers do not stack up.
- Route one: feasibility, planning and a tender-ready technical pack
- Route two: the same pack, then the build under one contract
- Either way the survey and feasibility work is identical, so the decision can wait
- Fees quoted per stage against the TR9 scope, not as one opaque figure
Scope
Where our work starts and stops on a TR9 project
Not every project needs every stage. On a Fraddon job we scope to what the site and the consent route actually require.
Construction and technical drawings
1:10 and 1:20 details for the parts of the job builders normally have to guess at.
Structural coordination
Calculations coordinated with the drawings so building control sees one consistent story.
Measured survey
An accurate record of what is actually there, which is where most avoidable cost is removed.
Planning application drawings
Existing and proposed plans, elevations, site and block plans drawn to validation standard.

Fraddon 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 Fraddon 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.
- 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.
- We live in the house. Can a loft conversion in Fraddon be done while we stay put?
- Usually yes for single-storey and rear work, with a temporary kitchen or bathroom arrangement agreed before the start. Whole-house remodels and roof work in Fraddon are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- 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.
Fraddon is part of St Columb Major
Fraddon sits inside the St Columb Major catchment — we cover both as one loft conversion territory.
