Stargazing domes & bubble rooms
A stargazing dome you can still use in February.
A solid polycarbonate bubble room with nothing overhead but sky — rated from −40 °C, so the stars are still available when the garden has snow on it.
Scene effect visualization — final configuration depends on site conditions.
Decide what the night is for.
Stargazing, a guest room with a view, dinner under the sky, or somewhere the children sleep out in summer — the use decides the size, the lighting and how much shading you need. For daytime garden uses such as plants, a workspace or somewhere to read, start with garden domes instead.
Move from an idea to a visible configuration.
Begin with the compact range.
- 2.1–3 m models are the practical home starting range
- Compare furniture footprint before selecting a shell
- Larger formats remain available when the site and use require them
- All Celenest sizes can be specified for commercial use

The room you end up using most.
A stargazing dome is not a summer house. It is the one room where the weather becomes something you watch instead of something that cancels your evening.
- Rain stops being a reason to go inside. It becomes the reason to go out — you hear it on the shell and see nothing but sky.
- Winter gets a room. Rated from −40 °C, the garden stops shutting down in November.
- The stars are the ceiling. No roof, no beams, no light spill from the house behind you.
- It becomes the children’s favourite place in the house, which is not in the house.
- It is quiet. Solid polycarbonate is 5–9 dB better than glass of the same thickness.
No installer arrives with it. That is the point.
Celenest ships EX-WORKS to buyers all over the world, so we do not send a crew. The shell is panelled precisely so that you do not need one.
- The shell arrives as 4–12 panels depending on model, with the roof cap, aluminium door and window, base profile and a complete fixing kit.
- Two or three people and ordinary hand tools. No crane, no welding, no wet trades.
- Step-by-step installation guidance is provided to every buyer, and we answer questions during the build rather than after it.
- Every part is identified on the packing list, so a damaged or missing item is ordered by number, not by description.
You are responsible for a level base or foundation, local permission where it is required, and any electrical work. We will tell you what the model needs before you order — ask, and it goes in the written quotation.
Check the garden before the cart.
- Usable level surface and foundation approach
- Door direction and path from the house
- Furniture, planting and view lines
- Power, drainage and neighbour privacy
Passive comfort is usually the sensible first step.
Use opening area, active top ventilation and shade before considering cooling equipment. Home buyers should also plan when the space will be occupied and how direct sun reaches it.
Know what DIY support does and does not cover.
- Confirm foundation and local permission before ordering
- Check access for delivery and panel handling
- Installation guidance does not replace local building expertise
- The quotation defines included parts, freight and optional accessories
See the scale before deciding.
Use verified product dimensions and labelled reference installations. Furniture mockups and concept scenes are planning aids, not proof of a completed customer project.
A bubble room, without the blower.
Most of what is sold as a bubble room is inflatable film held up by a fan that has to run all night. A Celenest stargazing dome is a solid Bayer polycarbonate shell. It holds its own shape, needs no power to stay up, transmits about 91% of visible light and is rated from −40 °C to 120 °C with a 10-year warranty. That is the difference between a night in a tent and a room with the sky for a ceiling.
- Sleeping under it. A 3.0 m takes a double bed with room to walk around it; the 3.5 m High adds head height for a bed and seating together.
- Where to put it. Point the door away from house lights and street lamps — light spill, not cloud, is what usually ruins a sky dome.
- Curtains matter more after dark. Interior light makes any transparent room visible from outside; zoned curtains close the lower half and leave the crown open.
- Winter is the season. The clearest skies come with the coldest nights, which is exactly when a fabric star dome stops being usable.
It arrives as a labelled kit — the eight assembly steps are on installation and shipping.
Stargazing dome questions, answered plainly.
What is a stargazing dome?
A stargazing dome is a transparent rigid shell you sleep or sit inside with an uninterrupted view of the sky. A Celenest clear dome is solid Bayer polycarbonate on an aluminium base ring, transmitting about 91% of visible light (ASTM D1003). So the sky stays the brightest thing in the room.
Can you actually see stars through a clear dome, or does it distort them?
You can see them. The panels are optical-grade sheet, not film, so there is no ripple or blur. What ruins stargazing is light spill, not the material — point the door away from house lights and street lamps and close the lower curtains.
Is a stargazing dome usable in winter?
Yes, and winter is when it works best. The shell holds its properties from -40 °C to 120 °C and is rated level 14 for wind. The clearest skies come with the coldest nights, which is exactly when a fabric or inflatable dome stops being usable.
How is this different from an inflatable bubble tent?
An inflatable stops being a room the moment the blower stops. A clear dome is a solid shell with nothing to inflate, no running fan and no annual film replacement. It also carries a 10-year warranty.
What size stargazing dome do I need?
For one bed and two chairs, 7.1 m2 (Round 3.0 m) is the usual starting point. For a double bed with room to walk around it, 9.6 m2 (Round 3.5 m High) is the common choice. Prices start at US$1,094 EX-WORKS.
