What we do
Most homeowners start the process without knowing one critical thing: Will this actually get approved?
And that is what we aim to establish from the very start. We don’t think planning permission should ever feel like a gamble.
We build out every client’s application around three principles: a clear planning strategy from day one, a design that aligns with policy (not fights against it), and a proposal that is actually viable in the real world. So whatever stage your project is at, we’re here to help get it started.

How it works
Your roadmap from enquiry to approval.
Four stages, one team — here’s exactly what happens after you get in touch.
01
Advice & Measured Survey
Every successful application starts with the right strategy. We assess what's realistically achievable before carrying out a detailed measured survey of your property, giving your project the strongest possible foundation.
02
Drawings & Planning Statement
We prepare clear, accurate drawings alongside a planning statement that explains your proposal in the language planning officers expect to see—maximising its chance of approval.
03
Submission & Council Liaison
Your application is submitted correctly the first time. We then manage all communication with the council on your behalf, answering questions and keeping your application moving.
04
Decision & Next Steps
Once a decision is issued, we'll explain exactly what it means and guide you through the next steps, whether that's starting your project or dealing with planning conditions.

Why us
Planning permission is complicated. Working with us isn't.
Most homeowners only submit a planning application once. You shouldn't have to become planning experts to get it right. That's why we've built a service that removes uncertainty at every stage getting our clients projects off the ground stress free.
One team from start to finish.
You'll deal with the same people throughout your project. Your survey, drawings, planning statement and submission are all handled together—not passed between separate companies who have never worked together.
Honest advice before you spend a penny on drawings.
If we don't believe your proposal has a realistic chance of approval, we'll tell you at the advice stage—not after you've invested time and money.
Stress Free Correspondence
Planning officers speak directly with us. We deal with every query, request and amendment, keeping your application moving and keeping you updated every step of the way while you get on with your life.

Frequently asked
The questions people actually ask us.
What happens if my application is refused?
We assess the risk of refusal honestly before you submit — if we don't think an application is likely to succeed, we'll say so at the advice stage, not after. If a refusal does happen, we review the council's reasoning and advise on amending and resubmitting or appealing, as part of our service.
How do I know I won't waste money on drawings that can't be built?
That's what the initial advice stage is for. We look at your property, the relevant planning policy and any site-specific constraints before a single drawing is produced, so you're making decisions with a clear view of what's realistic.
Do I need planning permission, or does permitted development cover me?
Often neither is obvious without a proper assessment — many projects fall under permitted development rights, some need a Lawful Development Certificate to prove it, and others need full planning permission. We work out which applies to you as the first step.
How long does the process take?
Councils have statutory timeframes for a decision once an application is validated — typically 8 weeks for householder applications, longer for larger schemes. Survey, drawings and preparation ahead of submission vary by project; we'll give you a realistic timeline for your specific case at the advice stage.
Will I deal with one person, or get passed between departments?
One team handles your project from initial advice through to the council's decision — including every piece of correspondence in between. You're not re-explaining your project to someone new at each stage.
Do you only handle the paperwork, or the design too?
Both. Drawings are prepared with approvability in mind from the outset, not just to illustrate what you've already decided — the two are handled together, not as separate handoffs.
