Can You Connect Two FlexPatio Pergolas Into One Larger Space?

Modular pergola expansion guide

Yes, FlexPatio currently sells separate modular expansion kits for joining compatible pergola units, but the connector is not universal. Match POWER+ units with the Basic kit and POWER+ PRO units with the Pro kit, then choose the connector length that matches the joining side. The current manuals also require the louvers to align in the same direction and use size-specific covers and hardware. Before treating an existing installation as expandable, confirm the exact generation, color, unit sizes, splice direction, foundation, power feeds, drainage path and local approvals in writing. A product listing alone does not prove that every finished pergola can be retrofitted without rework.

Start with the exact pergola series

The FlexPatio Modular Expansion Kit - Basic is currently described as a connector for multiple POWER+ pergolas. Its selectable connector lengths are 10 and 13 feet. The separate Modular Expansion Kit - Pro is listed for POWER+ PRO pergolas and offers 10-, 13-, 16- and 20-foot selections.

Those names and lengths define the first compatibility gate. They do not prove that two units with different generations, frame systems, colors or existing site conditions can be mixed. Record the product name from each order, the exact joining side and the manual linked to that connector selection. Ask FlexPatio to confirm the combination in writing before changing an installed structure.

The connector length follows the joining edge

Do not choose the kit from the finished overall size alone. The connector selection corresponds to the direction in which the units meet. For example, a larger layout assembled from two smaller units can have more than one possible orientation. The current manuals identify the applicable 10-, 13-, 16- or 20-foot direction and show the roof modules meeting along that edge.

The reviewed 10-foot Basic manual and 13-foot Basic manual both say the louvers should be aligned in the same direction. The Pro series repeats that requirement in its 10-foot, 13-foot and 20-foot manuals. The 16-foot Pro manual goes further by showing different cover combinations for two splice directions.

That size-specific detail is why a generic connector description is not enough. Obtain the manual for the exact side length and color variant. The manuals reviewed for this article are titled for white kits, while the product selectors also show gray. Confirm that the supplied parts and instructions match the ordered color rather than assuming the documents are interchangeable.

Plan two units as one site project

The current POWER+ Gen 2 page and POWER+ PRO Gen 2 page show extended configurations made from two units. Both pages also state that each pergola unit requires a separate power connection. A connector cover therefore should not be treated as permission to combine circuits, controls or electrical equipment. Have a qualified electrician review the actual units and the address.

Likewise, the connector does not merge two foundations into one approved support system. The installation drawings show the separate pergola frames and their posts. Check every post and base location, the condition and capacity of the supporting surface, access for assembly and the clear route around doors, steps and furniture. If either unit is already installed, measure the existing spacing and alignment instead of assuming nominal dimensions are sufficient.

Both connector product pages say the top cover channels rain into gutters. That describes the connector component, not a complete site drainage approval. Map where each unit receives water, how the gutters and posts discharge, and whether the expanded roof redirects runoff toward the house, a neighboring property or an area that cannot drain safely. Confirm the final path with the installer and local reviewer.

Check permits and approved documents again

Permit and HOA requirements vary by jurisdiction and property. The 2024 International Residential Code is a model code, not a universal local rule. Its administrative chapter covers permits for construction, enlargement and alteration, and it describes construction documents and site plans where required. The code adopted at the address, local amendments and the building official control.

If the first pergola was approved, do not assume that approval automatically covers an added unit. Ask whether the expanded footprint, post plan, foundations, drainage and electrical work require revised plans, a new permit or inspections. Separately ask any HOA whether its approval must be amended. Keep the exact manufacturer manuals and the approved drawing available for the installer and inspector.

Pre-order expansion checklist

• Identify the exact series, generation, color and size of both pergola units.
• Mark the joining edge and louver direction on a dimensioned site plan.
• Match the connector family and side length to the current product page and manual.
• Confirm the final post, base and foundation layout; do not assume a shared post can be removed.
• Plan a separate power connection for each unit unless approved documents state otherwise.
• Trace the complete gutter, post and site runoff path for the expanded roof area.
• Ask FlexPatio whether an existing installation can be retrofitted without structural or electrical rework.
• Confirm permit, inspection and HOA requirements for the final address and layout.
