Loft Conversions Malpas: TR1 planning, Mid Cornwall fabric
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 TR1 plot rarely works elsewhere — Malpas is a creekside settlement in the TR1 area, with waterside homes, wooded valleys and narrow-lane access shaping the brief, with a building stock that leans toward creekside cottages and waterside homes.
Malpas sits in Mid Cornwall — just off the A390; covering TR1 from Truro, St Michael Penkivel, Calenick outward.

Why Malpas is its own job.
Creekside ecology, flood risk, trees and views across the water often matter as much as the building form itself. That sets the scene before any design work begins. For loft conversion specifically, parts of Malpas sit within a designated Conservation Area, which means materials, fenestration and roof pitches all need to read sympathetically with the existing streetscape; coastal salt-laden air around Malpas drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. It's the kind of detail that decides whether a Malpas application gets approved at eight weeks or stalls in committee. The creekside cottages that dominate Malpas (and continue out toward Calenick) 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 Malpas.
01
Stairs eat space — a loft conversion lives or dies by where the new staircase lands and what it costs you on the floor below.
02
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.
03
Cut-roof Cornish properties are easier to convert than modern trussed roofs; the structural strategy varies completely.
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.

Who this is for
Our footing in Mid Cornwall
- Designated-area work is routine here, so heritage and landscape statements are produced alongside the drawings rather than outsourced.
- Drawings, planning and building regulations are all produced in-house, so a loft conversion enquiry does not get passed between firms.
- Design and build are offered from the same studio, which means the person answering your Malpas questions has seen the detail built.
Planning rules change and every site is different. For the final position on your address, check with Cornwall Council as the local planning authority or the Planning Portal.
Scope
Where our work starts and stops on a TR1 project
Clients in Malpas take different slices of this list, and that is deliberate.
Measured survey
An accurate record of what is actually there, which is where most avoidable cost is removed.
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.
Planning application drawings
Existing and proposed plans, elevations, site and block plans drawn to validation standard.
Heritage and design statements
Written justification where designation makes the design case as important as the drawing.
Page purpose
Drawings only, or drawings through to handover in Malpas?
Both routes are open on a TR1 project, and the honest answer depends on whether you already have a builder you trust. Plenty of Malpas 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 TR1 scope, not as one opaque figure
Our process
How a Malpas 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.

Parish & policy
Malpas sits in the parish of Malpas, which matters for how parish-level consultation lands on a loft conversion application.

Malpas 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 Malpas specifically, we'd start by checking the Conservation Area boundary 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.
- We live in the house. Can a loft conversion in Malpas 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 Malpas are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- 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.
- 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.
Malpas is part of Truro
Malpas sits inside the Truro catchment — we cover both as one loft conversion territory.
