Choosing a builder who handles plans and council, or coordinating yourself
Hire a builder to handle plans and council, or coordinate them yourself? Weigh the control, cost and communication trade-offs for your extension.
You've just bought a house that needs a second bedroom, or your kitchen has run out of space. Before you call a builder, you face a fork: do you hire someone who will handle all the planning applications and council liaison, or do you arrange an architect or draughtsman yourself and stay in the driving seat?
There's no universally correct answer—it depends on your tolerance for paperwork, your budget flexibility, and how involved you want to be. But the differences between these paths are real, and they affect not just cost and stress, but also the quality of your final outcome.
Outsourcing plans and council to the builder
When a builder offers to "handle everything," they're taking responsibility for getting drawings made (or reused from a previous job), submitting them to council, managing back-and-forth with inspectors, and obtaining the sign-off before construction starts. This sounds painless on paper.
The main appeal is simplicity. You sign one contract, make one phone call when you have a question, and don't need to learn what a building plan is or why council wants it. Your builder knows the local authority's quirks, has relationships with draughtsmen, and can usually predict turnaround times.
The catch is leverage and transparency. Once you've handed over responsibility, you can't easily see whether your builder is pushing hard for approval or letting it drift. If the plans come back requiring changes, you depend on the builder to communicate them clearly to you—and some don't. You also lose direct control over the design process. If the draughtsman misunderstands your brief, you might not notice until drawings land on your desk half-finished.
Cost-wise, expect the builder to add a margin on top of what they pay the draughtsman. This isn't dishonest; it's how they cover admin and risk. But you won't always see it itemised, which can feel opaque.
Coordinating an architect or draughtsman yourself
The alternative is to find and pay an architect or draughtsman directly, give them a clear brief, review their drawings, and hand the finished plans to your builder to cost and build. You then stay in regular contact with both parties.
This approach puts you in control. You steer the design, ask for revisions before they're final, and know exactly what the draughtsman charged. You also get direct feedback on what's feasible and what council is likely to demand—information flows both ways without a middleman.
The downside is that you become the project coordinator. You'll attend meetings with the draughtsman, chase them for updates, liaise with council yourself (or pay them to do it), and field questions from your builder if something isn't clear. This takes time and a willingness to ask questions that might feel obvious to professionals.
There's also a timing risk. If your draughtsman is slow, or council takes longer than expected, your builder might lose interest or block out dates for other jobs. You need either a fixed timeline in writing or flexibility to accommodate delays.
What actually matters in your choice
The real separators aren't about the path itself, but about the people involved. A builder who's worked closely with a particular draughtsman, knows what council needs, and actively communicates progress is easier to work with than one who disappears once you've signed. Conversely, a conscientious architect who's done dozens of additions in your area and has direct relationships with council staff can save you months of frustration.
Ask your shortlisted builders how they've handled plans before. Did they own the timeline or did clients coordinate? How often did their drawings come back with council objections? Do they push back on design ideas that will delay approval, or stay silent?
Talk to draughtsmen or architects about their council experience in your specific municipality. Some local authorities are stricter than others; someone who knows them well is worth their fee.
In practice, many builders work best when you hire your own draughtsman—it forces clarity and stops misunderstandings. Others genuinely streamline the process because they've made it routine. The difference is personal reliability, not the model itself.

Common questions
- Does outsourcing plans to the builder cost more?
- Yes, typically. The builder pays a draughtsman and adds an admin margin on top. If you hire your own draughtsman, you pay them directly and may save that margin, but you'll spend more of your own time managing the process.
- If the builder handles plans, do I still need to approve them?
- Yes. You should see and sign off on every drawing before it goes to council. If the builder shows them to you only after submission, that's a red flag.
- Which approach is faster?
- Not necessarily one or the other. A builder with a trusted draughtsman can move quickly; a draughtsman experienced in your local council can also be fast. The slowest scenarios usually happen when communication between parties breaks down.
- What if council rejects the plans and asks for changes?
- Either party can handle revisions, but you need clarity upfront on who pays for them and how long it will take. Include this in writing before work starts.
