Loft Conversions for Portloe (TR2)
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. Working in Portloe means starting from the TR2 context — Portloe is a harbour-side settlement in the TR2 area, with compact lanes, coastal exposure and a working-waterfront character, with a building stock that leans toward harbour cottages and granite terraces.
Portloe sits in Roseland — covering TR2 from Veryan, Pendower, Truro outward.

Our process
How a Portloe 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.
Local proof — Most Portloe loft conversion clients we work with are second-time builders — they've seen the templated approach fail once already.

Loft Conversions considerations specific to Portloe.
01
Cornish slate roofs come in a huge range of pitches — anything below a 30° pitch struggles to give usable headroom without raising the ridge.
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
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
Cut-roof Cornish properties are easier to convert than modern trussed roofs; the structural strategy varies completely.
Local context
Why Portloe is its own job.
In Portloe the planning picture is specific: harbour settings bring tight access, overlooking, flood risk and heritage character into play on even modest alterations. For loft conversion specifically, parts of Portloe sit within a designated Conservation Area, which means materials, fenestration and roof pitches all need to read sympathetically with the existing streetscape; the surrounding landscape falls inside the Cornwall Area of Outstanding Natural Beauty, so massing, height and landscape impact carry extra weight in any planning decision; coastal salt-laden air around Portloe drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. That local reading is what makes a Portloe (TR2) project different from a generic Cornwall scheme — and is the whole reason we work this way. On harbour cottages in particular — the kind you'll also find toward St Austell — the loft conversion brief always has to read the existing fabric first.
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.

FAQs
Portloe Loft Conversions — local questions answered.
- 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. In Portloe specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- 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.
- 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.
- 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.
