- One team, one point of contact, throughout
Three things we
take off your plate.
Drawings & design
Our in-house architects produce full architectural drawings for your project — included as part of the service. No need to commission a separate architect and no waiting around for external professionals before your build can progress.
Planning permission
Many extensions qualify under Permitted Development and need no planning application at all. Where planning is required, we prepare and submit everything on your behalf — and handle all correspondence with your local council throughout the process.
Building warrant
In Scotland, most extensions require a building warrant. Our team manages the full application — including all structural and thermal compliance documentation — and secures approval before your build begins. We also obtain the completion certificate at the end.
Your own architect
team. Included.
Most builders hand you a design and leave the paperwork to you. We don't. Our in-house architect team handles everything — from the initial drawings right through to planning permission and building warrant submission — so you never have to chase a council or decipher a regulation.

Architectural drawings
Full architectural drawings produced in-house. No third-party architects, no extra fees, no delays waiting on outside professionals.
Planning permission submission
We prepare and submit your planning application on your behalf, handling all correspondence with the local authority.
Building warrant application
Scotland requires a building warrant for most extensions. We manage the full submission and approval process, so you don't have to.
Build — and completion certificate
Once approved, our certified installation team builds your extension. We sign off the completion certificate, leaving you with a fully compliant, guaranteed build.
We know Scottish
planning inside out.
Planning rules in Scotland differ from those in England and Wales — and building warrants are a legal requirement that simply don't exist south of the border. Our team works exclusively in Scotland and knows exactly what Highland Council, Glasgow City, Edinburgh and every other Scottish authority expects to see in a submission.
From Permitted Development thresholds to conservation area requirements and listed building consents, we've navigated every kind of Scottish planning situation. We'll tell you upfront what your project needs and make sure it gets approved.
- Expert knowledge of Scottish Permitted Development Rights
- Building warrant applications as standard
- Experience with conservation areas & listed buildings
- Relationships with Scottish local authority planners

Planning & building
explained.
Do I need planning permission for an extension in Scotland?
Not always. Many extensions qualify under Permitted Development Rights and don't require a planning application. We'll assess your project upfront and let you know exactly what's needed — and if planning is required, we handle the full submission for you.
What is a building warrant and do I need one?
A building warrant is a legal requirement in Scotland for most structural building work, including extensions. It's separate from planning permission and confirms the build complies with Building Regulations. Our team manages the full application as standard on every project.
How long does planning and warrant approval take?
Permitted Development confirmation is usually quick. Full planning applications typically take 8–12 weeks. Building warrant applications run in parallel and are often approved within a similar timeframe. We'll give you a realistic timeline at the start of your project.
Is the modular system Building Regulation compliant?
Yes — the modular system is pre-approved by Stroma, Assent and MFA Building Control and is fully Building Regulation compliant. This pre-approval makes compliance fast and straightforward, with minimal back-and-forth with inspectors.
What if I'm in a conservation area or have a listed building?
These situations require additional consents but are absolutely manageable. Our team has experience navigating conservation area consent and listed building applications across Scotland, and will advise you on what's achievable and how to approach your local authority.
Do you provide a completion certificate?
Yes. Once your extension is built, we obtain the completion certificate from Building Control confirming the build meets all required standards. This is an important document you'll need if you ever sell your home.
