Professional large shed assembly - 8x10ft and bigger. Built perfectly square with watertight roof, properly anchored walls, and doors that actually open and close properly. Full day service for serious garden buildings.
Proper Garden Buildings
Large sheds are different to small 6x4 units. An 8x10, 10x12, or workshop-sized shed is a proper garden building - with serious panels, heavy roofing, and the potential to go very wrong if not assembled correctly.
🏠 Built to last. Taking time to get it square, watertight, and solid. Not rushing to tick boxes.

🔧 DIY Tips
Building it yourself? Here's what matters:
🔧 Tools you'll need
- Cordless drill with bits
- Spirit level (long)
- Rubber mallet
- Step ladder
- Socket set
📐 Key steps
- Check base is PERFECTLY level first
- Follow panel sequence exactly
- Check square constantly
- Don't fully fix until frame is verified
- Felt overlap goes DOWN the slope
⚠️ Common mistakes
- Building on unlevel base
- Rushing wall assembly
- Poor felt overlap (causes leaks)
- Skipping weatherproofing seals
💡 Pro trick: Check diagonals at every stage. Measure corner to corner both ways - when they're equal, the frame is square. Even 1cm difference compounds into problems with doors.
Rather leave it to a pro? No problem - that's what I'm here for. Give me a call.
Good to Know
🏗️ Get the base right - I can't stress this enough. An unlevel base means a twisted shed with doors that don't close and gaps that leak. If your base isn't ready, we reschedule.
Weather:
- Need dry, calm conditions
- Will postpone if rain forecast
- Safety over schedule
Treatment:
- New sheds need timber treatment
- Annual treatment extends life
- Pay attention to end grain and joints
Frequently Asked Questions
What size counts as 'large'?
I consider 8x10ft and bigger as large sheds - they're a different job to smaller 6x4 units. Large sheds take a full day or more and often have additional features.
Do I need a concrete base?
Strongly recommended. Large sheds are heavy and can warp if the base isn't level and solid. The base must be ready before assembly day.
Do large sheds need planning permission?
Usually not if under 2.5m height, 2m from boundaries, and under 50% of garden. Check with Exeter Council - I build sheds, not planning advice.
Can you install the base too?
I can advise and install simple timber bearer bases. Concrete bases need a builder or groundworker.
