Loft Conversions in St Merryn
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 St Merryn version of this work has its own character — St Merryn is a rural parish in the PL28 area, with farmsteads, lanes and scattered homes defining its built character, with a building stock that leans toward farmhouses and rural cottages.
St Merryn sits in North Cornwall — just off the A39; covering PL28 from Padstow, St Eval, Trevone outward.

Who this is for
In St Merryn 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 St Merryn
Not every project needs every stage. On a St Merryn job we scope to what the site and the consent route actually require.
Full design and build
One contract from first sketch to handover, with the same team on paper and on site.
Building regulation drawings
Full Plans sets with sections, construction notes and coordinated structural information.
Planning application drawings
Existing and proposed plans, elevations, site and block plans drawn to validation standard.
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.

Other work we do around St Merryn
St Merryn is covered from our Padstow 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 St Merryn?
Both routes are open on a PL28 project, and the honest answer depends on whether you already have a builder you trust. Plenty of St Merryn 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 PL28 scope, not as one opaque figure
Local context
Why St Merryn is its own job.
Open-countryside policy, access lanes, drainage and agricultural building history all need to be addressed before drawings go too far. 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. So every St Merryn job runs as a PL28-specific piece of work — local policy, local fabric, local builders. Most of our loft conversion work in St Merryn lands on farmhouses, with detailing that has to nod to the wider St Eval 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 St Merryn.
01
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.
02
Cut-roof Cornish properties are easier to convert than modern trussed roofs; the structural strategy varies completely.
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.

FAQs
St Merryn Loft Conversions — local questions answered.
- 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. In St Merryn specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- We live in the house. Can a loft conversion in St Merryn 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 St Merryn 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.
- 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.
St Merryn is part of Padstow
St Merryn sits inside the Padstow catchment — we cover both as one loft conversion territory.
