Skate Park and Street Sports
Walk a fenced concrete skate park: a closed bowl, half pipes, a funbox, rails, a street stair with a handrail, and the boards, bikes and kit left around a session.
About
A riverside concrete park built entirely from the pack's modular pieces, with the street furniture and the gear that surround a real one.
What is placed. Flat ground tiles lay the floor and raised pad blocks lift the plaza. A bowl closes from four corner sections, six straights and six painted coping runs; quarter pipes, half pipe sections, a bank ramp, a launch ramp, a funbox plain and railed, a grind box, a ledge, a flat rail and a kinked rail fill the park; a five step stair and its handrail make the street section. Chain link panels and a hinged gate fence the plot, with graffiti panels on two runs, floodlight masts, benches, bins, bollards, planters, a drinking fountain, a bleacher, cones and signs. Boards, a BMX, a scooter, inline skates, helmets, pads, shoes, backpacks, bottles, a bearings box, a skate tool, a boombox and a filming tripod are left where a session leaves them.
What moves. Skateboard, BMX, scooter and inline skate wheels spin, the fence gate swings open and closed, and the litter bin lid lifts.
What does not move, and why. The chain link mesh, the grip tape, the BMX drivetrain and the tripod legs are static geometry: each is cloth, a texture or a linkage that a rigid node transform cannot drive honestly. There are no skaters, because nothing here is skinned.
Every piece here is a published model from the pack, placed by hand. Walk with the keys or touch, and approach a piece to see it move if it has animation. Colliders, navigation and gameplay are yours to add.
Points of interest
Funbox and rails
The funbox comes plain or with a grind rail across it, beside a grind box, a flat rail and a kinked rail. Every piece sits on the same four metre grid as the floor tiles.
Funbox with Grind Rail (Skate Park and Street Sports)Half pipe
A half pipe section with a painted deck edge, next to the quarter pipes and the bank ramp. Sections butt together on their ports to make a longer run.
Half Pipe Mini Ramp Section (Skate Park and Street Sports)Street stair
A five step concrete stair with its handrail, set into a raised plaza block. This is the street section people build a line on.
Five Step Concrete Stair Set (Skate Park and Street Sports)The bowl
Four corner sections, six straights and six painted coping runs close into a bowl by port arithmetic alone. Drop in anywhere round the ring.
Bowl Corner Wall Section (Skate Park and Street Sports)Bleacher
Boards, a BMX, a scooter, inline skates, a helmet, pads, a backpack, a bottle and the skate tool are left around the bleacher the way a session leaves them. The wheels spin as you pass.
Spectator Bleacher (Skate Park and Street Sports)Graffiti wall
Painted panels run along two of the fence lines, with floodlight masts, benches, bins, bollards and planters filling the apron around the park.

Models in this demo
Flat Concrete Ground Tile (Skate Park and Street Sports)
A 4 x 4 m poured concrete pad tile, 150 mm thick, with two shallow saw cut joints across it. Tiles butt edge to edge on the 4 m grid to lay a skate park floor of any size.
Bowl Corner Wall Section (Skate Park and Street Sports)
A quarter turn of the same bowl wall inside a 3.0 x 3.0 m square, swept about a 1.2 m inner radius. Its two end ports meet straight sections, so four corners and any number of straights close a bowl.
Bowl Straight Wall Section (Skate Park and Street Sports)
A 4 m run of bowl wall: a 1.5 m transition from the floor to vertical with a 0.3 m deck lip. End ports chain straights and corners into a closed bowl and the coping port takes the coping edge piece. Sink the ring for a below grade bowl.
Bowl Coping Edge Piece (Skate Park and Street Sports)
A 4 m coping run: a steel coping pipe bedded on a thin painted fillet, sized to the bowl wall deck lip. Its seat port drops onto a bowl straight section's coping port.
Raised Pad Block (Skate Park and Street Sports)
A 4 x 4 m concrete plinth 0.9 m tall with a proud capping slab and a painted edge band, the raised plaza a street stair set drops off. Blocks tile on the 4 m grid and the top ports take a stair set.
Five Step Concrete Stair Set (Skate Park and Street Sports)
The same stair run five risers deep, 0.90 m down to the pad: the street set that a handrail and a five stair gap are built around.
Street Stair Handrail (Skate Park and Street Sports)
A 1.84 m round steel handrail on two footed posts, pitched to the five step stair set. The foot port drops on the pad and the head port on the top landing.
Concrete Bank Ramp (Skate Park and Street Sports)
A 4 m wide flat bank rising 0.9 m over a 3 m run, with a painted top edge and a 1 m deck. 4 m front to back, so the deck meets a raised pad block on the 4 m grid; the pad port sits on the low edge.
Concrete Quarter Pipe Ramp (Skate Park and Street Sports)
A 4 m wide quarter pipe with a 1.6 m transition, a steel coping pipe on the lip and a 0.7 m deck behind it. Rides toward -Z; the pad port sits on the front edge on the 4 m grid.
Half Pipe Mini Ramp Section (Skate Park and Street Sports)
A 4 m wide section of a 1.4 m mini ramp: two facing transitions on a poured floor slab, a 2.4 m flat bottom, coping pipes on both lips and 0.4 m decks. Sections butt end to end to make a ramp of any width.
Concrete Funbox (Skate Park and Street Sports)
A 4 m wide funbox: a 2.8 m flat deck 0.6 m up with a bank at each end and painted steel edging on both top lips. Boxes butt end to end along the 4 m grid.
Funbox with Grind Rail (Skate Park and Street Sports)
The funbox with a 3.4 m steel grind rail standing 0.3 m above its deck on two posts. Same footprint and the same end ports.
Steel Edged Grind Box (Skate Park and Street Sports)
A 2.4 x 0.55 m concrete grind box 0.45 m tall with chamfered top corners, a steel angle capping each grinding edge and a painted band down each side.
Concrete Ledge Block (Skate Park and Street Sports)
A 1.6 x 0.6 m precast ledge 0.4 m tall with one chamfered grinding edge and a sprayed paint band on the face. Drops straight onto the pad.
Flat Grind Rail (Skate Park and Street Sports)
A 3 m round steel grind rail 0.4 m above the ground on two splayed painted A frames with bolted footplates.
Kinked Grind Rail (Skate Park and Street Sports)
A 3 m round steel rail that kinks up at both ends, the street handrail shape, on two splayed painted A frames.
Portable Launch Ramp (Skate Park and Street Sports)
A 1.2 m wide kicker 0.5 m tall over a 1.5 m run, with a curved face and a steel lip bar. Small enough to carry out and drop anywhere on the pad.
Chain Link Fence Panel (Skate Park and Street Sports)
A 4 m bay of 2.4 m park fencing: a capped post on the start end, top and bottom rails and a welded wire grid. The mesh is a simplified rigid grid, not a hanging chain link, so it never moves.
Chain Link Fence Gate Bay (Skate Park and Street Sports)
The same 4 m bay with a teal framed access leaf hung on the start post and a latch on the closing stile. The leaf is one node on its hinge line; the mesh inside it is rigid.
Graffiti Wall Panel (Skate Park and Street Sports)
A 3 x 2.6 m precast boundary panel on a wide foot, sprayed with five blocks of colour and their outlines. Panels butt edge to edge into a painted wall of any length.
Park Floodlight Mast (Skate Park and Street Sports)
An 8 m tapered lighting column on a cast base with a crossarm and two tilted floodlight heads with pale lenses. No embedded light source.

A concrete pedestal fountain with a stainless top, a shallow bowl, a bubbler spout and a push panel on the front. No water.
Skate Park Warning Sign (Skate Park and Street Sports)
A 1.75 m post sign: a yellow board with a bordered panel and three blank text bars, the notice board a park entrance carries. The text is geometry, not lettering.
Concrete Street Planter (Skate Park and Street Sports)
A 1.2 m precast planter with a dark soil bed and five clipped shrubs on short stems. Static.
Traffic Cone (Skate Park and Street Sports)
A 650 mm orange cone on a square foot with a reflective collar. Static.
Portable Boombox (Skate Park and Street Sports)
A two speaker portable stereo with a carry handle, a cassette door pressed into the fascia, four buttons and a raised aerial. Nothing opens.
Phone Filming Tripod (Skate Park and Street Sports)
A 1.2 m three leg tripod with a phone cradle on a short head, set up to film a trick. Deliberately not rigged: the legs and the head are one solid, because a telescoping leg needs a joint per section.
Complete Skateboard (Skate Park and Street Sports)
A 81 cm complete: maple deck with a kicked nose and tail, gripped top, printed underside, two trucks and four urethane wheels on their own axle nodes.
Skateboard Resting Deck Down (Skate Park and Street Sports)
