City Road Street Baseplate – 10in x 10in Building Block Base Plate

Every Great City Build Starts with the Right Foundation

There is a specific frustration that every building block enthusiast knows: you have the bricks, you have the vision, and then you realise your base is wrong. A flat, featureless plate gives you nowhere to start. A mismatched road layout breaks the flow of your city. The City Road Street Baseplate solves that problem at the foundation level — a purpose-designed 10in x 10in (25.5 x 25.5cm) road base plate that gives your city build the realistic street infrastructure it needs to come alive.

Available in four road configurations — Straight, Curved Road, T Junction, and Crossroads — these baseplates are designed to connect and combine, allowing you to build out a complete road network that scales with your city. Start with a single crossroads at the centre of your layout and expand outward with straight sections, curves, and junctions until your city has the road infrastructure of a real urban environment. The modular design means every plate connects seamlessly to the next, with no gaps, no misalignment, and no compromises.

Compatible with Small Particle Building Blocks

The City Road Street Baseplate is fully compatible with small particle building block systems — the standard used by the most popular construction toy brands. Every stud on the plate accepts standard small particle bricks, allowing you to build directly on the road surface: pavements, buildings, vehicles, street furniture, and anything else your city needs. The road markings and lane details are moulded into the plate itself, so the street layout looks realistic from the moment you place it down, before you add a single additional brick.

This compatibility makes the baseplate a versatile foundation for any city-themed build — whether you are recreating a specific urban environment, building a fantasy city from scratch, or simply expanding an existing layout that needs more road infrastructure. The CE-certified plastic construction meets safety standards for children aged 6–12 and is durable enough to withstand the handling and rebuilding that serious builders put their sets through.

Four Road Configurations to Build Any City Layout

The four available configurations cover every road type a city builder needs. The Straight plate provides the main arterial roads and long stretches between districts. The Curved Road plate allows you to create sweeping bends, roundabout approaches, and organic street layouts that avoid the rigid grid of a purely straight-line city. The T Junction plate creates the side-street intersections that give a city its neighbourhood character. The Crossroads plate is the centrepiece of any city layout — the main intersection where roads meet and traffic flows.

Mix and match configurations to build the exact road network your city requires. Each plate is sold individually, so you can order exactly the configurations you need in the quantities your layout demands. Note: price includes one base plate only; no additional accessories are included.
