Composite decking boards on an allotment

An ROD allotment (Family Allotment Gardens) is the perfect place for a weekend reset, a family barbecue or a peaceful evening surrounded by greenery. More and more allotment holders are choosing to build a terrace, making everyday life easier and leisure time more comfortable. But one question arises: which material should you choose? Are composite decking boards on an allotment a brilliant choice or perhaps an unnecessary expense? Are they really a low-cost solution for years to come? 


What are composite decking boards and why are they worth considering?

Composite decking boards are a hybrid material, made from a mixture of wood flour and plastics. This means they combine the look of wood with the durability of plastic. They are currently one of the most popular alternatives to traditional timber terraces, particularly in gardens and on balconies.

Why are composite decking boards appealing to allotment holders?

  • They are durable – they do not rot, crack or decay,
  • They do not need treating – saving you time and money,
  • They look elegant and modern,
  • They are easy to install – even a DIY enthusiast can manage,
  • They are ideal for the changeable weather typical of allotment gardens.

A terrace on an ROD allotment – is it worth it?

The answer is: YES, for many reasons:

  • You have a clean, stable place to relax,
  • You do not track sand and mud into the garden shed,
  • You can set out garden furniture without it sinking into the ground,
  • It looks tidy and makes the allotment more functional.

But... every allotment holder knows that budget matters. So let us see whether composite is worthwhile for an allotment.

Composite decking boards for the garden – cost and value for money.

At first glance, composite decking boards seem more expensive than ordinary timber. But is that really the case?

Cost comparison: 
Item Pine timber Composite decking boards
Price per m² approx. 80–100 zł approx. 120–200 zł
Preservative treatment (annual) approx. 20–30 zł/m² 0 zł
Durability 5–10 years 20–30 years
Maintenance every season minimal
 
 The verdict? Composite may require a greater initial investment, but after a few years... it simply pays for itself! Especially if you want to avoid annual repairs, painting and replacing boards.
 

Where are composite decking boards best suited to an allotment?

Best places to use them: 

  • A terrace by the garden shed or allotment cabin,
  • Garden paths between the beds,
  • A platform for garden furniture or a barbecue,
  • A place to relax with a sun lounger and parasol.

Composite decking boards go beautifully with greenery, aggregate, lawns and even paving. This means they enhance the appearance of even the simplest allotments.


 

A low-cost solution – can composite be budget-friendly?

Yes! Here are a few tricks to reduce costs: 

  1. Buy during a sale or from end-of-line collections – manufacturers often clear older models.

  2. Install it yourself – you can save as much as 30% of the total cost.

  3. Use it only in key areas – for example, a small terrace and a path.

  4. Choose cheaper brands – but make sure they have good reviews and certificates.

Advantages of composite decking boards on an allotment. 

PROS:

  • No need to paint or oil them,
  • They are resistant to rain, snow and frost,
  • They do not absorb water – no problem with rot,
  • They do not crack or peel,
  • You can walk barefoot – no splinters!

This is what makes them an increasingly popular choice for allotment owners as a practical, long-lasting solution.

What about the drawbacks? Find out before you buy. 

CONS: 

  • Higher initial cost (although this evens out),
  • Not everyone likes their "artificial" look (especially older models),
  • They may get slightly warm in strong sunlight,
  • Some cheap models may warp – choose reputable manufacturers.

How do you install composite decking boards on an allotment?

The good news: you don't have to be a professional builder to lay composite decking yourself.

Step by step:

  1. Prepare the base – ideally a gravel bed or concrete blocks,
  2. Install the joists (wooden or aluminium),
  3. Secure the boards using fixing clips,
  4. Allow for expansion gaps – composite decking expands in the sun!

And that's it – you have an allotment terrace for many years to come!

FAQ – frequently asked questions. 

  1. Are composite decking boards suitable for an allotment?
    Yes, they work very well in gardens and on allotments, especially if durability and convenience matter to you.
  2. Are composite boards non-slip?
    Modern models have a non-slip surface – safe even after rain.
  3. How much does a small composite terrace cost?
    With DIY installation, a 3x2 m terrace costs around 1000–1500 zł – as a one-off expense.
  4. Does it need maintenance?
    No – seasonal cleaning with water or a pressure washer is enough.

Is it worth it or not? 

If you value: durability, appearance, convenience, and peace of mind for years to come...

...then composite decking boards on an allotment are a worthwhile investment. You don't have to worry about damp, mould, cracks or treating the boards. Just one solid installation – and your terrace is taken care of for many seasons.

Is this solution for everyone? Maybe not. But if you value peace of mind and free time instead of scrubbing and painting, the answer is simple: it's worth it!
