Thinking about adding a deck to your garden? Our comprehensive guide covers everything from planning permission to step-by-step construction for your Hertfordshire garden.

Planning Permission

Good news! In most cases, you don't need planning permission for a deck if:

Choosing Materials

Softwood - Cheaper but requires annual treatment. Expected lifespan: 10-15 years.

Hardwood - Beautiful, naturally durable. More expensive. Expected lifespan: 25+ years.

Composite - Low maintenance, won't rot. Mid to high cost. Expected lifespan: 20-30 years.

Basic Construction Steps

  1. Mark out the area and check it's level
  2. Install concrete footings or posts
  3. Build the frame using joists
  4. Lay and secure the decking boards
  5. Add finishing touches - rails, steps

Pro Tip

Leave a 5-8mm gap between boards for drainage. This prevents water pooling and extends the deck's life.
