Most municipalities in Massachusetts, Rhode Island, Connecticut, New Hampshire, Vermont, and Maine require permits for permanent outdoor structures.

Timber frame pavilions typically require concrete footings or sonotube piers designed to support the structural post loads.

Yes, but some preparation is required.

For existing paver patios, a section of pavers approximately 24 to 30 inches in diameter is removed at each pavilion post location. Concrete piers are then installed beneath the patio.

The top of the pier is typically set about one inch below the paver level. After the pavilion is installed, the pavers are reinstalled and cut around the posts.

Post stand-offs are used to keep the timber posts elevated above the patio surface.

For smaller pavilions, concrete footers or piers are installed according to the provided drawings that specify the required locations and specifications.

For paver patios, the tops of the footers are typically installed just below the bottom of the pavers.

For concrete slabs with footers, the tops of the footers may either be installed just beneath the slab surface or level with the slab surface, depending on the installation approach.

If installing a new paver patio, it is often recommended to install the pavilion first and then install the pavers afterward.

Larger timber frame pavilions require properly sized concrete footers or piers installed according to the provided drawings.

For concrete slab patios, the tops of the footers may be installed level with the slab surface or approximately four inches below the finished patio surface.

Four-inch post stand-offs are typically used to keep the timber posts elevated above the patio surface.

In some installations, the pavilion structure is installed first and the concrete slab is poured afterward.

Each pavilion post is anchored to the concrete foundation using steel post brackets and wedge anchor bolts.

A flat concrete surface is required so the bracket can sit properly. During installation, the installers drill into the concrete and secure the structure using wedge anchor bolts designed for structural support.

No. Brackets or J-bolts should not be wet-set into the concrete ahead of time.

The installers will handle the anchoring process during installation to ensure proper alignment, correct placement of the posts, and structural stability.

This helps ensure the pavilion is installed accurately and safely.

Like any natural wood structure, occasional cleaning and stain maintenance will help preserve the timber’s appearance and longevity.

Cabot Australian Timber Oil

• Composition: Contains a blend of linseed oil, long-oil alkyds, and tung oil
• Purpose: Designed specifically for dense, exotic hardwoods (like mahogany, teak, and ipe)
• Appearance: Enhances the natural grain with a deeper, richer finish
• Protection: Provides good UV protection and water resistance
• Penetration: Superior penetration into dense hardwoods
• Drying time: Typically 24-48 hours between coats
• Reapplication: Usually requires reapplication every 1-2 years
• Application: Oil-based, so cleanup requires mineral spirits

Haley's Ultra Timber Frame Stain

• Composition: Typically a water-based acrylic formula with UV inhibitors
• Purpose: Formulated specifically for timber frames and large wooden structures
• Appearance: More consistent color with less dramatic grain enhancement
• Protection: Excellent UV and weather resistance
• Penetration: Better for softwoods and structural timbers
• Drying time: Generally faster drying (often 4-6 hours between coats)
• Reapplication: Typically lasts 3-5 years before needing reapplication
• Application: Easier cleanup with soap and water if water-based

The best choice depends on your specific project. Cabot is excellent for dense exotic woods and when you want to enhance natural grain patterns, while Haley's is better for timber frame structures and when you want longer-lasting protection with less frequent maintenance.

• Optional 5V & standing seam metal roofing (available in several colors).
