Loft Conversions that reads Heamoor 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. Reading Heamoor on the ground is half of the loft conversion job — Heamoor is a residential village on the northern edge of Penzance, originally a separate hamlet, now effectively a suburb with its own primary school and parish identity, with a building stock that leans toward 1930s semis and modern new-build estates.
Heamoor sits in West Cornwall — covering TR18 from Penzance, Madron, Gulval outward.

Parish-level character expectations that don't appear on any policy map
Who this is for
Heamoor runs the full mix — owner-occupier, holiday-let, commercial and the occasional smallholding — so we scope every loft conversion enquiry from the use-class up.
Local context
Why Heamoor is its own job.
Around Heamoor (TR18), within Madron parish; outside Conservation Area and AONB. Edge-of-Penzance development pressure has driven significant new estate housing in the last twenty years. For loft conversion specifically, Heamoor sits outside the headline designations, which usually gives a slightly more flexible starting point — but parish-level character still matters. Reading Heamoor properly up front saves more time than any drawing tool ever will. Most of our loft conversion work in Heamoor lands on 1930s semis, with detailing that has to nod to the wider Penzance 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 Heamoor.
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
Cornish slate roofs come in a huge range of pitches — anything below a 30° pitch struggles to give usable headroom without raising the ridge.
03
Cut-roof Cornish properties are easier to convert than modern trussed roofs; the structural strategy varies completely.
04
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.
Our process
How a Heamoor 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.
FAQs
Heamoor 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 Heamoor specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- 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.
- 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.
- 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.
Heamoor is part of Penzance
Heamoor sits inside the Penzance catchment — we cover both as one loft conversion territory.
