LM Build & Design
by LMMods
LM Build & Design adds extra building blocks for Fabric, including portal blocks that link to the Nether, carved stone panels, metal ducts, cardboard boxes and crystal glass.
What it does
The blocks are aimed at construction work, where a builder needs more decorative material than vanilla provides. Two portal blocks take a player to the Nether and back to the Overworld, so they can serve as transit points in a build. Carved stone panels, metal ducts with vents, cardboard boxes and crystal glass give walls, interiors and facades more variety.
The mod runs on the client and on the server, so every player who joins a server running it needs it installed too. Files exist for Fabric only, for four game versions: 1.21.8, 1.21.9, 1.21.10 and 1.21.11, with 2026.1 for 1.21.11 as the latest file, published on 2026-02-20. It is released under the MIT License but is not open source, and it is part of the LM Mods collection by LMMods.

How it compares
Carved is a Fabric mod for 1.21 – 1.21.4 with a different focus on carved pumpkins, and its license is All rights reserved, so it is not open source. Create's-cardboard is a Fabric mod for 1.20.1 under the MIT License, and it is open source, while LM Build & Design covers 1.21.8 – 1.21.11 and is not open source. Fancy Glass is also Fabric-only for 1.20.1 under the MIT License and open source, so it does not cover the same versions as this mod.
