SketchUp model of a wooden terrace, pergola, and garden sofa for production

It is necessary to develop in SketchUp the first stage of the production 3D model of the outdoor module line based on this visual reference:

I would like to point out that this reference is entirely AI-generated, so it likely contains many unrealistic joints and strange dimensions.

In the first stage, it is necessary to design only 3 objects:

1. Terrace — basic size of 4×4 m, with the possibility of further scaling to other sizes.
2. Gazebo — according to the size of the terrace.
3. Garden sofa — 1 basic model.

The other objects shown in the visualization — chair, table, firewood rack, storage module, coat rack, bin, gazebo framework, garland, and other elements — will be designed later, in the second stage. For now, they should be perceived only as a general stylistic reference for the future line.

The task of the first stage: to create models suitable for production, detailing, BOM, and cutting.

Style: minimalist wooden outdoor, clean lines, even gaps, simple geometry, without complex radii, without decorative overload. The construction should look like a neat outdoor furniture product, not like a temporary construction.

All models must be assembled from real separate wooden elements: beam, board, slat. Monolithic decorative objects or board imitation with texture are not allowed. Each structural element must be a separate component/group with a clear name, real size, and assembly logic.

Design only from the basic library of wood sections:

1. Beam 150×150 mm — gazebo posts.
2. Beam 100×100 mm — module posts, furniture legs, supports.
3. Beam 50×200 mm — main beams of the gazebo.
4. Beam 50×150 mm — load-bearing frames, bindings, large crossbars.
5. Beam 50×100 mm — joists, frames, crossbars, furniture frames.
6. Board 20×140 mm — cladding, tops, facades, seats, tabletops.
7. Slat 20×40 mm — slats, framework, hidden strips, small elements.

If a different size is needed, please agree on it first.

Requirements for the SketchUp model:

• scale 1:1, units — millimeters;
• each element as a separate component or group;
• components named systematically;
• all elements have real sections and lengths;
• the terrace and gazebo must be suitable for resizing;
• the sofa must be a separate module that can be arranged in the scene;
• fasteners can be shown conditionally, but assembly joints must be clear;
• simple assembly, replaceability of parts, and realistic production must be provided.

What needs to be delivered for the first stage:

1. SketchUp file with the terrace, gazebo, and sofa.
2. A general scene with the arrangement of these three objects.
3. A parts table/BOM: part name, section, length, quantity, material/type of element.
4. Preliminary cutting according to the parts.
5. The project should clearly show the assembly diagrams.

After completing this stage, it will be possible to proceed to the design of the other modules (as part of a separate project).
