About training Construction

Construction is the purest gp-for-xp trade in the game: you buy planks, put a demon butler on delivery duty, and build-then-demolish the same furniture in your player-owned house over and over. With deep pockets it becomes one of the quickest 99s available, needing only around 16-30 hours of actual building past level 52, while the Mahogany Homes minigame offers a slower contract-based route that cuts the total bill by more than half.

Did you know: Speed-running 52-99 with mahogany tables means slapping down and demolishing about 15,400 tables, feeding roughly 92,000 mahogany planks (about 180M gp) to your butler in only ~16 hours of clicking.

How this Construction estimate is built

11,558,850 XP separates level 77 from Construction 99, out of 13,034,431 total. 950,000 XP/hr on Gnome benches turns that gap into 12 hrs; 840 XP per bench turns it into 13,761 actions. One action every 3.2 seconds: that is what 950,000 XP/hr at 840 XP per bench actually requires. Every row carries an action count here - all 8 Construction methods - so that column is never blank. 9 nights at 1.4 hrs a day covers 12 hrs of Construction. 15 hrs from level 1, if you switch at 33/50/52/70/74/77.

Decision example

11,558,850 XP: Gnome benches converts it in 12 hrs, Oak dungeon doors in 24 hrs - 98% more clock. The faster row costs more: 165.3M gp against 101.7M gp for the same 11,558,850 XP. Low attention instead: Mahogany Homes (expert) at 170,000 XP/hr.

Limits of the number

950,000 XP/hr is Gnome benches over a session, 1,282,500 on a perfect tick. An hour of Gnome benches burns about 13.6M gp in supplies. Prices are 16 October 2026 estimates: 14.3 GP/XP today, and the Construction cost moves with supply.

Construction, level 77 to 99

11,558,850 XP - 89% of a whole 99 - explained twice. Both rows price the same 11,558,850 XP, so only the Construction rate and GP/XP move.

A practical Construction route

3 stages, 1-33 to 70+: each names the Construction method to switch to and what the switch buys.

  1. 1-33
    Quest and low-tier builds

    Use quest rewards and cheap furniture to reach the first useful house upgrades without buying a complete 1-99 stack.

  2. 33-70
    Oak, teak or mahogany

    Oak larders and dungeon doors are practical, teak benches raise speed, and mahogany tables cost more for faster XP.

  3. 70+
    Build around unlocks

    Pool, jewellery box and portal upgrades often matter more than the next level; use mahogany homes when you want contracts and less material waste.

Construction by goal

What changes the choice

  • Fastest: Mahogany tables or dungeon doors rely on a butler, noted planks and a close bank; setup time is part of the real route.
  • Lower cost: Mahogany Homes and oak furniture reduce GP/XP at the cost of travel and contract actions.
  • Account utility: Stop at the house upgrades you need, then return later; construction XP does not provide value if the unlock is already complete.

Requirements and caveats

  • House location, butler, saw, hammer, noted-plank method and stamina supplies determine the practical rate.
  • Plank and servant costs move with GE prices; the displayed GP/XP excludes the value of the finished house upgrade.
Common mistakes to avoid
  • Buying all planks before checking the current margin and the target house unlock.
  • Using a rate that assumes a butler and noted planks without having the required house or coin pouch setup.
