Loft Conversions that reads Hatt properly
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. A Hatt brief starts on the street, not the screen — Hatt is a commuter village in the PL12 area, with everyday family housing, edge-of-village plots and quick routes to its parent town, with a building stock that leans toward modern estates and garden infill plots.
Hatt sits in East Cornwall — just off the A38; covering PL12 from Saltash, Landrake, Tideford outward.

Who this is for
In Hatt the loft conversion brief is almost always a private homeowner improving a forever home — so we lead with feasibility and long-term value, not show-home rhetoric.
Scope
The parts of the job we can take on in Hatt
Clients in Hatt 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.

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.
Who this is for
What we can genuinely back up in Hatt
- Applications for Hatt are handled through Cornwall Council, with Liskeard the nearest planning office we deal with regularly.
- Drawings, planning and building regulations are all produced in-house, so a loft conversion enquiry does not get passed between firms.
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.

Other work we do around Hatt
Hatt is covered from our Saltash run. Being a smaller place, the local detail matters more than the headline policy: lane access, neighbour proximity and what the immediate street already looks like.
Page purpose
Drawings only, or drawings through to handover in Hatt?
Both routes are open on a PL12 project, and the honest answer depends on whether you already have a builder you trust. Plenty of Hatt 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 PL12 scope, not as one opaque figure
Local context
Why Hatt is its own job.
Around Hatt (PL12), 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. Reading Hatt properly up front saves more time than any drawing tool ever will. Most of our loft conversion work in Hatt lands on modern estates, with detailing that has to nod to the wider Landrake streetscape.
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 Hatt.
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
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.
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.

FAQs
Hatt 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 Hatt 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.
- 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 Hatt 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 Hatt are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
