Building Regs for Lerryn (PL22)
Building regulation drawings in Cornwall, drawn properly. Approved planning gets you permission to build — a complete building regs package is what gets you a building you can actually live in: 1:50 plans, 1:10 details, structural coordination and a specification a Cornish builder can price and build from without guesswork. The way we approach building regulations package in Lerryn starts with a measured walk-round — Lerryn is a creekside settlement in the PL22 area, with waterside homes, wooded valleys and narrow-lane access shaping the brief, with a building stock that leans toward waterside homes and detached houses.
Lerryn sits in South Cornwall — just off the A39; covering PL22 from Lostwithiel, St Winnow, Lanlivery outward.

Why Lerryn is its own job.
In Lerryn the planning picture is specific: creekside ecology, flood risk, trees and views across the water often matter as much as the building form itself. For building regulations package specifically, parts of Lerryn sit within a designated Conservation Area, which means materials, fenestration and roof pitches all need to read sympathetically with the existing streetscape. That local reading is what makes a Lerryn (PL22) project different from a generic Cornwall scheme — and is the whole reason we work this way. On waterside homes in particular — the kind you'll also find toward Sweetshouse — the building regulations package brief always has to read the existing fabric first.
Planning note
Building regulations are a separate consent track from planning. Drawing them properly upfront is the cheapest insurance you'll buy on the project.
What we focus on
Building Regs considerations specific to Lerryn.
01
Coastal sites need explicit material and fixings choices in the spec — stainless or non-ferrous fixings, salt-resistant cladding and breathable build-ups.
02
Part L and the Future Homes Standard route now drives a meaningful share of the build cost; getting the U-values and air-tightness strategy right at design stage saves money on site.
03
Cornish exposure ratings are among the worst in the country; wind-driven rain detailing matters more here than in most of the UK.
04
Granite walls, traditional cob, slate-hung elevations and rubble construction all need different building regs detailing than standard masonry.

Page purpose
What you actually get on a Lerryn building regulations package drawings package
This is a drawings-led service. You are buying a documented, submission-ready set for a PL22 address, not a build contract. For most Lerryn householders that means a measured survey, an honest feasibility view, then the drawings the council and your builder both need.
- Measured survey and existing drawings before any proposal is drawn
- A written planning route for the PL22 address, including whether permitted development is realistically available
- Proposed plans, elevations and site plan at the scales the authority expects
- Submission and validation handling, plus responses to officer queries

How a Lerryn building regulations package project runs.
Step 1
Design freeze
We confirm the planning-approved scheme as the basis for technical design.
Step 2

Step 3
Detailing
Construction details drawn at 1:10 for every junction that matters.
Step 4
Specification
Materials, U-values, finishes and workmanship written up so the builder can price accurately.
Step 5

Lerryn Building Regs — local questions answered.
- What happens if something changes on site?
- Site queries are part of the job. We respond directly to the builder during construction, issue revised details where needed and keep building control informed if the change is material. In Lerryn specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- Can the builder work without building regs drawings?
- They can — and many do — but the cost gets recovered later in variations, mistakes and slower building control sign-off. A proper regs pack typically pays for itself several times over on anything beyond the smallest job.
- Who do you submit to in Cornwall?
- Either Cornwall Council building control or one of the Approved Inspectors active in the county. We're happy to recommend, but the choice is yours.
- Do you coordinate with a structural engineer?
- Yes — every project that needs steel, timber or masonry calculations is coordinated in-house with a Cornish structural engineer we work with regularly.
- Building Notice or Full Plans?
- Full Plans gives you a formal approval before work starts and a clean paper trail for resale. Building Notice is faster and cheaper up front but less protective. We default to Full Plans for anything other than very simple work.
- We live in the house. Can a building regulations package in Lerryn 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 Lerryn are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
Lerryn is part of Lostwithiel
