Is Building Depot an authorized MegaDome dealer?

Yes. Building Depot is Ontario's Authorized MegaDome Dealer and sells the full MegaDome series (HP, HHP, XP, XL, DB and AR) with Ontario-stamped engineering and manufacturer warranty.

What warranty does Building Depot offer?

MegaDome fabric membranes carry a 15-year prorated warranty, and hot-dip galvanized steel frames are engineered for a 50+ year service life. Foundations and installation carry a 1-year workmanship warranty.

Can a multi-purpose dome really host sports and community events?

Yes, with planning. Movable nets, partition curtains and modular floor markings let the same clear-span floor host a soccer program in the morning and a community event in the evening. The layout, mechanical design and flooring all need to account for every intended use from the start.

How is the floor built to handle different activities?

Slab finish and any flooring overlay are chosen around the mix of uses — turf infill, sport tile or hard concrete each behave differently, and transitions between them are planned at the foundation stage, not added afterward.

What size of dome supports community-scale versus regional use?

Community-scale multi-purpose buildings are often narrower footprints serving one municipality's programming. Regional facilities hosting tournaments or larger events need a wider clear span for run-out, seating and circulation. Tell us the mix of programs and expected attendance and we'll size it.

Do multi-purpose domes need HVAC?

Most year-round facilities run some combination of make-up air, heat and destratification fans, sized to the mix of activities and occupancy. Our engineering team integrates the mechanical package into the shop drawings.

What foundation does a multi-purpose dome need?

A perimeter footing or stem wall and a slab designed for the range of activities and equipment loads planned inside, including any staging or seating. Building Depot designs and pours the foundation and erects the building under one contract.

Can an existing community dome be replaced or expanded?

Yes. We assess the existing foundation and frame for reuse, or design a new structure sized to your current and future programming.

What do you need from us to scope a multi-purpose dome?

Site address, the list of activities and events planned, expected peak attendance, any seating or staging requirements, and your target opening date. That's enough for a preliminary layout and budget.

ONE ROOF, SEVERAL PROGRAMS

The best multi-purpose domes work every day of the week.

A community dome earns its footprint by staying busy — a sports program in the morning, a different activity at lunch, a community event on the weekend. Clear span removes the columns that would otherwise force a single-use layout, and movable nets, partition curtains and modular floor markings let the same slab serve different programs through the week without a rebuild between them.

→Clear-span widths sized to your full activity and event list
→Mechanical and lighting integrated at the shop-drawing stage
→Stamped engineering for any Ontario snow and wind zone
→Membrane warranty terms confirmed in the issued documents

Interior of a clear-span multi-purpose fabric dome set up for a community event — Concept image of a multi-purpose interior. Layout and dimensions are set per project.

Configurable Interior

Clear-span volume with no interior columns, so nets, curtains and floor markings can reconfigure the space between uses.

Daylit Multi-Use Floor

A translucent membrane spreads diffuse natural light across the whole floor, whatever program is running that day.

Built for a Full Calendar

Doors, storage and circulation planned around switching between sports, events and community programming through the week.

Engineered for Ontario Loads

Stamped to the snow, wind and seismic loads of your site, wherever in Ontario the building sits.

SIZING THE BUILDING

Start with the full calendar, not one activity.

A multi-purpose dome is sized around everything it has to host, not just the primary sport or event. These are the inputs we use before any dimension is quoted:

→The full list of activities and events the building has to support
→Expected peak attendance for the largest event planned
→Whether seating, staging or a stage-adjacent area is required
→Storage for movable nets, curtains, chairs and event equipment
→Circulation and exit routes sized for public assembly, not just sport use
→Whether the building is community-scale or intended for regional events

Send those details and we will come back with a footprint, a foundation approach and a preliminary budget range. Preliminary figures are for budgeting only — final pricing follows engineering, site conditions and the configuration you select.

Get a preliminary project budget

Community-scale

Serving one municipality's recreation and event programming in a smaller footprint.

Regional-scale

Sized for tournaments, fairs or larger events drawing attendance beyond the local area.

Seasonal flex

A layout that shifts easily between summer and winter programming.

Phased builds

A first phase designed to accept an addition as programming grows.

FOUNDATION & TECHNICAL PACKAGE

One floor, several kinds of load.

A floor that has to carry a sports program one day and staging, seating or vendor booths the next needs to be engineered for the full range of use, not just the lightest one. We design the footing or stem wall, the slab and the frame connections as one system, then pour it and erect the building with our own crews so the schedule stays under one contract.

→Slab designed for the heaviest activity or event load planned
→Door and opening placement matched to both sport and event traffic
→Mechanical rough-ins coordinated before the pour
→One contract from excavation through commissioning

Flooring transitions

Slab finishes planned where turf, court surface and hard flooring meet, or where event flooring overlays go down.

Storage capacity

Space for nets, curtains, chairs and event equipment built into the plan, not left to a hallway.

SITE & PLANNING CHECKLIST

What we walk through before drawings start.

Drainage and grading

Site grading and roof drainage planned so runoff moves away from entrances and event parking areas.

Parking and access

Vehicle counts for the largest event on the calendar, not just a typical sports booking.

Foundation and floor

Footing or stem wall and slab designed for the mix of activity loads and any staging or seating equipment.

Approvals

Permit drawings for your municipality and occupancy classification review tied to public assembly use.

A building that hosts public events draws more site-plan and occupancy scrutiny than a single-activity building. We plan for it up front rather than discovering it at permit review.

WHO WE BUILD FOR

One building, several stakeholders.

Municipalities and school boards

Community recreation buildings that need to justify their footprint across sports, events and public programming.

Agricultural societies and fairs

Buildings hosting seasonal fairs, trade shows and livestock events alongside recreational use the rest of the year.

Private event and sports operators

Businesses booking the same floor for both athletic programming and private functions.

Developers and community partnerships

Joint-use projects pairing a multi-purpose dome with adjacent municipal or school infrastructure.
