Builders' Construct is a simple Tinkers' Construct addon that adds two new Abilities: Construction and Angel Building.
Construction
With this ability, your tool can place up to 5 blocks of the block you're looking at. You can also put a block in your off-hand to place that block instead.
The Expanded Ability available in base Tinkers' increases that range.
No Expanded: 5 blocks
Expanded I: 9 blocks
Expanded II: 16 blocks
Expanded III: 32 blocks
Expanded IV: 64 block
...
You can also change mode by shift right-clicking while not looking at a block:
Fill: Fills all blocks possible
Horizontal: Places blocks in a horizontal line
Vertical: Places blocks in a vertical line
(Note that Horizontal and Vertical always point towards north and not the players' rotation)
Angel Building
With this ability, your tool can place blocks from your off-hand midair.
