Oak Pergola Styles, Specifications & Prices (3×3 m and 4×4 m)

At Timber Solution, we design and manufacture a wide range of oak pergolas — from timeless, classic lattice designs to sleek, modern structures. Every pergola is handcrafted from premium European oak and can be supplied as a pre-cut kit or a fully bespoke build tailored to your space.

We use substantially larger oak sections than many competitors, ensuring greater strength, rigidity, and long-term durability. The price of each oak pergola depends on the beam sizes and design features selected by the client.

Standard Oak Pergola Specifications

Every Timber Solution pergola includes:

• Pre-cut oak posts: 145 × 145 mm
• Oak headplates: 100 × 145 mm to 145 × 145 mm (depending on style and span)
• Oak braces: 50 × 150 mm
• Joists / rafters: 60 × 140 mm with a 150 mm overhang
• Traditional kild dried oak pegs M16

These dimensions provide exceptional stability and a premium appearance. Some pergola models include additional design features — such as lattice panels, trellis, slatted sides, or feather-edge cladding — many of which can be added at no extra cost. You can explore all available upgrades and design variations on our website.

Factors That Affect Oak Pergola Installation Time

Installing a 3 × 3 m oak pergola is usually a 2–3 day job, but the exact time can vary depending on several important factors:

Weather Conditions

• Rainy weather: Post holes may fill with water, and concrete cannot set properly. This delays work by 1–2 days.
• Windy weather: Handling heavy oak beams becomes unsafe and slows down assembly.

Carpenter Skills & Team Experience

• An experienced oak frame carpenter can align posts and assemble joints faster.
• Less experienced installers may take longer to square the structure and fit beams securely.

Quality & Preparation of the Oak Frame

• Factory-prepared kits (with joints pre-cut and mortise/tenons ready) reduce installation time dramatically.
• If joints need cutting or adjusting on-site, it adds extra hours or even another day.

Weight of the Beams

• Oak is extremely dense. A 150 × 150 mm post (3 m long) can weigh around 50–70 kg.
• Main beams (spanning 3 m, 200 × 100 mm or larger) can weigh 60–90 kg each.
• Lifting requires at least 2 strong workers, or even machinery for larger spans.
