1) Plan the Platform Layout

Consider the following:
● Where will the dome be located?
● Would you like to have an outdoor lounge area, kitchen, bathroom, or even an outdoor bathtub?
● Also take Hungarian and local building regulations into account!

2) Test the soil

It is important that the platform is built on stable, compacted soil to prevent it from sinking over time.
To ensure this, it is recommended to examine the soil layers at several points on the planned site using a shovel, drill, or even an excavator.

3) Clear the Area

Remove vegetation and make sure it doesn’t grow back.
This helps prevent weeds, insects, or small animals from settling underneath the platform.

4) Foundation (Post Base, Ground Screw, Concrete, etc.)

Choose from the following options:
● Ground screws installed manually or with machinery
● Point foundations prepared by soil drilling
● Pre-fabricated footings

Important: it must be deep and strong enough depending on soil type and regulations.

5) Install Beams (Main Carriers)

The orientation of the main beams will determine the direction of the remaining structural elements (planks, decking).
It’s advisable to choose timber sizes that minimize waste from cutting.

6) Install joists

General rule: about 45 cm spacing is ideal to support the weight without sagging.
Always follow applicable standards for the chosen timber.

Tip: If the platform is directly on the ground, this is the stage to install utilities (water, electricity, sewage), as it will be difficult later.

7) Place Structural OSB or Plywood under the Dome

Use moisture- and insect-resistant plywood under the dome, because:
● The dome will cover it anyway, so expensive finish isn’t needed here,
● The board gives a solid base for the interior flooring.

Tip: Cut the panels straight (not in the dome’s curve), so the exterior finish will align nicely later.

8) Lay Decking Boards

If the previous steps were done accurately, laying the deck will be straightforward.
Don’t forget to leave 4–6 mm gaps between the boards for expansion.

Later, once you’re halfway done, it’s worth measuring again to avoid having to rip the last boards lengthwise.
● Also take Hungarian and local building regulations into account!

9) Install Railings, Stairs, Bracing

Regulations vary by county!
Check whether railings, handrails, or structural bracing are required—especially if the platform is elevated.

10) Surface Treatment – Stain or Paint (Optional)

This is not only for style but also for timber protection!
If you’re using timber that doesn’t need treatment, you can skip this step.

11) Install Blocks for Dome Anchoring

After assembling the dome frame, you need to reinforce the anchoring points from below using blocks.
We recommend using solid wood blocks of at least 90 mm thickness to ensure all anchor bolts hold firmly.
