Block Expansion: Essential

This addon has been discontinued and will no longer receive updates. It's being reworked into something bigger and more flexible. More info in the pinned comment.

Ever felt limited by the blocks in the base game? Block Expansion: Essential fixes that, bringing in missing variants like vertical slabs, vertical stairs, and more. Every addition is designed to feel like it’s always belonged, giving builders the freedom to craft exactly what they imagined.

This add-on focuses on expanding building possibilities by introducing missing block variants that naturally fit alongside the base game. It is designed to provide more complete options for players, allowing ideas to be realized without being limited by the default selection of materials.

All additions are designed to align with the game’s existing style and systems, so they feel natural to use in both survival and creative gameplay. The goal is not to introduce something entirely new, but to extend what already exists, making building more flexible while keeping everything cohesive and balanced.

Some features are not yet available due to existing limitations in custom blocks themselves. For example, custom stairs cannot connect with vanilla stairs as this would require Beta APIs, which this add-on intentionally avoids in order to ensure smooth performance across all devices. Even so, the add-on already expands the building experience by giving olayers more freedom to create, experiment, and refine their designs while keeping everything cohesive. Future updates will continue to improve, expand, and complete the overall experience.

More blocks are added to significantly expand building possibilities. Each block is designed to complement the base game’s existing content, giving players a wide range of options for construction, decoration, and creative experimentation. The additions aim to feel natural, cohesive, and versatile across different building styles.

New slab and stairs variants are included, with many more planned for future updates. These variants provide precise building tools and greater flexibility, addressing limitations that existed in the base game. The list of upcoming additions will continue to grow as the project evolves, keeping builders engaged and expanding creative possibilities.

Designed for survival and achievements, all content maintains balance and compatibility with core gameplay. Players can enjoy the expanded building options without breaking progression, while achievements remain accessible and meaningful. The goal is to enhance the survival experience rather than complicate it.

Functionality and mechanics are carefully implemented so that every block behaves naturally within the game’s existing systems. Placement rules, interactions, and in-game logic are all aligned with vanilla behavior, ensuring that new content feels intuitive and fully integrated.

All additions are crafted to match the base game’s visuals, sounds, interactions, and overall behavior. This attention to detail ensures a seamless experience, making it feel as if the blocks were always part of the game, while still providing fresh options for creative expression.

This add-on requires version 26.0 or higher to function properly. Achievements remain enabled, and no experimental gameplay toggles are required. Simply install the pack and use it in your world without additional setup.

Personal use and content creation including YouTube and streaming are permitted. Use in other add-ons is allowed with proper credit. Redistribution without permission, claiming the work as your own, and selling or monetizing this add-on directly are strictly not allowed.
