How a dome goes up

Triangles, then light.

01 Site & base

Level, anchored, legal.

Setbacks and permits are checked with your town, and lines are located. Then a level base goes in: a gravel ring, piers or ground screws.

02 Lower frame

The first rings of struts.

Struts and hubs bolted ring by ring on a low insulated knee wall. The shape holds itself up as it closes.

03 Upper frame

Triangles to the top.

Each triangle shares the load, which is why domes stand up to snow and wind so well.

04 Glazing

Clear panels, sealed tight.

Twin- or triple-wall polycarbonate panels are screwed and sealed, with a door and vents so it never overheats.

05 Inside

Warm light in January.

Beds or a floor, a cushion or a bench. A bright, sheltered room in the darkest months.

A new offering

What yours could look like.

Domes are new for Heartmind Spaces, so there are no project photos yet. These illustrations show the kind of dome and garden we design.

Kit makers’ own photos are a good guide to what a finished dome looks like.

Every space is different, so pricing comes after a free walkthrough.

Care & warranty

Living with a dome.

3-year warranty on the build (frame, panels and base we installed), plus a care guide to keep it looking right. Plants, gravel settling and water upkeep are maintenance, not warranty items. Your written quote spells out exactly what’s covered.

  • Open the vents on sunny days, even in spring. Domes warm up fast.
  • Brush heavy wet snow off the lower panels if it builds against the knee wall.
  • Wash the panels with mild soap and a soft cloth, never abrasives.
  • Check panel screws and seals each spring.

Questions

Geodesic domes FAQ.

All FAQs

How much does a geodesic dome cost?

Every yard is different, so pricing comes after a free walkthrough. The kit, site prep, base, anchoring and assembly depend on your yard and are quoted after a visit.

Do I need a building permit?

Often, yes. Ontario only exempts small storage sheds (up to 15 m², storage only). A greenhouse or garden room is usually an accessory building, and many towns want a permit over 10 m², which is about a 12 ft dome. We check with your town before anything is ordered.

Will it handle our snow?

A well-anchored dome with the right glazing sheds snow well, and Canadian kits are rated for heavy loads and high winds. Heavy wet snow banked on the lower panels is worth brushing off.

Can it be used all winter?

For sitting on sunny days, yes. Growing through deep winter needs a four-season kit with triple-wall panels, an insulated knee wall and some heat.

Does it need a foundation?

It needs a level, anchored base: a gravel ring, concrete piers or ground screws. Larger domes with permits may need a specific design.

Can you assemble a kit I’ve already bought?

Often, yes. Tell us which kit it is, and we’ll check what’s needed at the walkthrough.

Does it get too hot?

Without vents, yes, quickly. Every dome gets a door and intake and exhaust vents, and many kits include solar fans.

Can I add power or heat?

Yes, through a licensed electrician. We plan conduit and placement with them.

How long does it take?

Expect about 1–2 weeks on site after the town check and kit delivery. The exact time depends on size and ground.

Have you built domes before?

Domes are a new service for Heartmind Spaces, and we’re now booking our first projects. We work from established Canadian kits, check permits and setbacks with your town first, and put the plan and price in writing.

Is there a warranty?

Yes, a 3-year warranty on the build: frame, panels and base we installed. If something we built fails within three years of completion, we come back and fix it. You also get a care guide. Plants, gravel settling and water upkeep are maintenance, not warranty items. Your written quote spells out exactly what’s covered.

Choosing a size

Size decides more than you think.

Bigger feels better inside, but floor area changes the paperwork. Rough guide (diameter → floor area):

  1. About 7–9 m²

    10–11 ft

    A quiet room for one or two, or a small greenhouse. Often under permit thresholds.

  2. About 10.5 m²

    12 ft

    Right on the line in many towns. Check first.

  3. About 16.4 m²

    15 ft

    Room for beds and a bench. Usually needs a permit.

  4. About 24–35 m²

    18–22 ft

    A true four-season greenhouse. Permit, drawings and a proper foundation.

Ontario only exempts small storage sheds (up to 15 m², storage only) from permits. A greenhouse or garden room is usually an accessory building, and many towns want a permit over 10 m². Zoning setbacks apply at any size.

How the space helps

What you may notice afterwards.

A room for quiet

A place to sit, read or practise, away from the house but close.

Winter light

A bright, sheltered spot on grey January days.

A longer season

Greens started earlier in spring and picked later into fall.

Somewhere to walk to

A destination at the end of the garden path.

While we work, we practice Dissolve: nothing carried into the space but care. About the practice

Glossary

What the terms mean

The words you may see in your quote.

Frequency (2V, 3V)

How finely the triangles are divided. Higher frequency is rounder and has more struts.

Struts and hubs

The straight pieces of the frame and the metal connectors where they meet.

5/8 dome

A dome taller than a half-sphere, for more headroom at the edges.

Polycarbonate glazing

Twin- or triple-wall clear panels that insulate and won’t shatter.

Knee wall

A low insulated wall the dome sits on. It adds headroom and keeps frost out.

Ground screws / screw piles

Steel anchors twisted into the ground instead of pouring concrete.

Setbacks

How far a structure must be from property lines and other buildings, set by zoning.

Accessory building

A detached building on your lot that isn’t the house. Many towns need a permit over 10 m².
