99 Construction on the Way to Max: Mahogany Homes vs the Gold Sink, and What a Bought Max Cape Really Proves

Maxing an Old School RuneScape account is never just one sprint; it is a sequence of deliberate gold sinks, time investments, and mental resets. Among the 24 skills, Construction occupies a unique role: it is the most expensive buyable to train the traditional way, yet it produces no direct GP return. What it produces is infrastructure—a player-owned house that becomes the account's command centre for every other grind that follows. Whether you are planning the 99 yourself or evaluating a maxed account listing, the method behind the Construction cape tells you more than the cape itself.

For sellers and buyers, 99 Construction is a signal. It says the account owner either had deep pockets, serious patience, or both. It also means the POH is fully built out, which instantly raises the account's quality-of-life ceiling. This guide breaks down the two real training paths—traditional POH building and Mahogany Homes—compares their gold sink profiles, and then looks at what a max cape actually proves on a second-hand account.

Why 99 Construction Is the Maxing Breakpoint

Construction is not the flashiest skill, but it is the one that quietly upgrades the entire account. A maxed player-owned house becomes a one-stop teleport nexus, a prayer and hitpoints restore point, a free item repair station, a place to swap spellbooks, and a storage room for every untradeable you will ever earn. When you are grinding the last 10 million XP across the remaining skills, the POH is where you recharge between runs. A maxed account without 99 Construction is like a sports car without a garage: fast, but always homeless. This guide is for two kinds of player: the maxing main who needs to plan the gold sink efficiently, and the buyer evaluating a maxed account listing that already shows the Construction cape. In both cases, the numbers matter, but so does the method behind them.

Training Construction is a pure gold sink. Planks leave the game, nails disappear, and the only thing that comes back is XP and a house full of conveniences. The traditional POH method is brutally efficient but costs a fortune in mahogany planks. Mahogany Homes trades speed for a smaller bill, but it still demands travel and inventory management. Understanding both routes—and when to switch between them—is the difference between a smooth 99 and a burned-out bank account.

Requirements and Starting Blocks: What You Need Before the First Plank

The first step is always the house purchase or the miniquest. Daddy's Home is strongly recommended because it skips the early grind entirely and gives you a starter supply crate. After that, you will be building and removing furniture inside your POH in building mode. To enter building mode, open the Settings menu, select House Options, and toggle Building Mode to on. You will then see ghost hotspots where furniture can be built. Each hotspot has level requirements and costs specific materials. Your early levels will be eaten up by crude wooden chairs and wooden bookcases before oak becomes the backbone of the skill.

Estate agents can be found in Varrock, Falador, Seers' Village, East Ardougne, and Hosidius. They sell the Construction cape for 99,000 coins once you hit level 99, and they also allow you to move your house to different locations. Your house starts in Rimmington, but you can move it to Taverley (10), Pollnivneach (20), Hosidius (25), Rellekka (30), Aldarin (35), Brimhaven (40), Yanille (50), or Prifddinas (70) for a fee. Location matters for training efficiency: Rimmington is useful early because Phials the un-noter is right next to the portal, but later you will likely switch to a house near a bank or a more central hub.

The Traditional POH Grind: Fast XP at a Brutal Price

The classic method is to stand inside your POH, build a piece of furniture, remove it, and repeat, using a servant or Phials to un-note planks. This is the fastest XP in the game because it eliminates travel time, but it also burns through planks at an alarming rate. The progression usually follows the cheapest effective item at each tier: from crude chairs at level 1, through oak larders at 33, to mahogany tables at 52, and finally teak garden benches or oak doors if you want to vary the rhythm. Each build-and-remove cycle grants XP, and the only cost is the planks and nails consumed per action.

The numbers above assume Grand Exchange prices and do not include servant costs, un-noting fees, or teleport runes. Mahogany planks are the priciest per XP, but they give the highest XP per hour because each action is worth 840 XP. If you train with mahogany tables from 52 to 99, you will consume a staggering number of planks—enough to fund a small POH empire. This is why many maxing players use a hybrid approach: traditional building when they want raw speed, and Mahogany Homes when they want to preserve cash.

Mahogany Homes: The Budget Route with a Travel Tax

Mahogany Homes is a Construction minigame where you complete repair contracts for NPCs in Falador, Varrock, East Ardougne, and Hosidius. Instead of standing still and building the same item, you travel to a client's house, repair or replace several pieces of furniture, and then return to a contractor for a new assignment. The planks you use depend on the contract tier: Beginner requires normal planks, Novice uses oak planks, Adept uses teak planks, and Expert uses mahogany planks. Higher tiers offer more XP per contract but cost more in materials.

The minigame rewards carpenter points that can be spent at the Mahogany Homes Reward Shop. The most valuable purchase is the Carpenter's outfit, which gives up to 2.5% bonus Construction XP with the full set. You can also buy Amy's saw, a wieldable saw that saves an inventory slot, and a plank sack that stores planks. The outfit and plank sack are long-term investments that pay for themselves if you plan to do a lot of Mahogany Homes or train Construction on multiple accounts.

Mahogany Homes is slower than traditional POH training, but it is significantly cheaper per XP because the contract completion bonus reduces the effective cost per plank. It is also less repetitive, which helps with burnout. The main drawbacks are travel time and inventory management: you need to carry the right planks and sometimes a steel bar, and you must navigate to four different cities. Teleport tabs, fairy rings, and house portals all help, but you will still spend a chunk of each contract running.

Cost Comparison: POH Planks vs Mahogany Homes Contracts

Deciding between traditional POH training and Mahogany Homes comes down to two numbers: your GP per hour and your tolerance for repetition. The traditional method is always faster XP per hour, but its cost per XP is higher because every action consumes planks with no bonus. Mahogany Homes gives bonus XP on contract completion, which effectively lowers the cost per XP, but the travel time cuts into your hourly XP rate. As a rule of thumb, if you can make more than the difference in cost per hour by bossing or flipping, traditional training is better. If your bank is limited or you are funding 99 Construction with gold you bought, the slower but cheaper route may be smarter.

Players should verify the current Grand Exchange prices for oak, teak, and mahogany planks before choosing a method. Prices fluctuate with supply and demand, and a spike in mahogany plank prices can suddenly make Mahogany Homes far more attractive. Likewise, if teak planks drop, teak garden benches become an excellent middle ground. Do not trust old cost-per-XP tables; always recalculate with live prices.

Servants, Phials, and the Butler Economy: Minimizing Bank Time

One of the biggest hidden costs of Construction is the time you spend fetching planks. If you run to a bank after every inventory, your XP per hour collapses. The solution is to un-note planks without leaving the house area. In Rimmington, Phials will un-note planks for 5 coins each, which is cheap early on but requires running back and forth between the portal and his shop. Once you have level 40 Construction and at least two bedrooms with beds, you can hire a servant from the Servants' Guild in East Ardougne. The human butler is faster than Phials, but the demon butler is the gold standard from level 50 onward. Servants can fetch planks from your bank and un-note them for a fee, and they can be paid automatically if you build a servant's money bag in a bedroom at level 58. The demon butler's speed is worth the extra cost during long training sessions.

To use a servant efficiently, keep your inventory filled with notes, have cash in your money bag or inventory, and stand next to the hotspot you are building. Send the servant to the bank, build while he is gone, and repeat. This reduces downtime dramatically. If you are training with Mahogany Homes, servants are less critical because you are moving between cities, but a house teleport with a mounted glory or ornate jewellery box can speed up travel.

Equipment and Boosts: Squeezing Every Drop of XP

Construction XP boosts are small but they add up over millions of XP. The Carpenter's outfit from Mahogany Homes gives 2.5% bonus XP with all four pieces. The crystal saw from The Eyes of Glouphrie provides a +3 visible Construction boost, which lets you build items three levels early. The Imcando hammer, obtained from the Ruins of Camdozaal, is a wieldable hammer that frees an inventory slot, and Amy's saw from the Mahogany Homes reward shop does the same for the saw. These inventory-space savers are especially valuable during traditional training, where every slot counts.

Passive Construction XP can also come from other activities. Repairing Wintertodt braziers grants XP equal to four times your current Construction level per repair. Fishing Trawler gives 5 XP per leak fixed while you earn the Angler's outfit. Restoring masts and totem poles at Tempoross and the Vale of Eternal Blossoms gives level-based XP. These methods are not fast enough to replace active training, but they can shave off a few early levels or provide a change of pace.

What 99 Construction Unlocks: The Cape and a Fully Loaded POH

At level 99, you can buy the Construction cape from any estate agent for 99,000 coins. The cape provides unlimited teleports to your player-owned house and to any house portal, making it one of the most convenient capes in the game. Combined with the max cape, which inherits all skillcape perks, you get a single item that teleports you to a fully built POH with a pool, jewellery box, portal nexus, spirit tree, fairy ring, and occult altar. Those rooms require high Construction levels to build: the superior garden (level 65) hosts the ornate pool, the achievement gallery (level 80) hosts the jewellery box, and the portal nexus (level 72) consolidates teleports. A maxed POH is often considered the single best quality-of-life upgrade in OSRS.

For a maxed account, 99 Construction is mandatory, but it is also the skill that most directly improves every other skill's training loop. The POH becomes your bank, prayer restore, and teleport hub all at once. When you are doing Slayer, clues, or bossing, you will return to the POH dozens of times per hour. The cape itself is a flex, but the house is the real reward.

The Max Cape Context: 99 Construction as One Tile in the Mosaic

The max cape is the ultimate symbol of account completion. It is sold by Mac on his island west of the Warriors' Guild for 2,376,000 coins — exactly 99,000 per skill. To reach Mac, you need 99 in Agility, Crafting, Construction, Defence, Mining, and Woodcutting, plus a pickaxe and an axe. The cape inherits all skillcape perks, so if you own the Construction cape perk, the max cape gives you that same POH teleport on top of every other teleport and boost. If you later decide to sell the cape back, Mac will buy it for 1,900,800 coins as long as you have both the cape and hood.

On a bought account, the max cape is a certificate of completion, but it does not prove the original owner did the work. For a buyer, the value is in the infrastructure: a maxed POH with all utility rooms built, a bank full of untradeables, and perhaps a cosmetic collection. 99 Construction matters because it means the POH is already at full power, and the account can immediately be used for endgame PvM or skilling without building anything. That is worth real GP in the account market.

Burnout and Pacing: A Level-by-Level Roadmap Without Hating the Skill

Construction is notorious for being one of the most repetitive skills in OSRS. Standing in one spot and clicking the same spot thousands of times will wear down even the most dedicated player. The key to avoiding burnout is to break the journey into phases and switch methods when your wrist or your bank account complains.

1. Levels 1–33: Complete Daddy's Home for a free jump to 8, then build crude chairs and wooden bookcases until you can use oak larders. This phase is cheap and fast.
2. Levels 33–52: Oak larders are the classic mid-game method. Use a servant or Phials to un-note planks, and consider doing some Mahogany Homes contracts to break up the monotony and earn Carpenter's outfit pieces early.
3. Levels 52–74: Mahogany tables are the fastest XP, but teak garden benches are cheaper. Alternate between the two based on your current gp buffer. If you need a mental break, run Expert Mahogany Homes contracts for variety and point collection.
4. Levels 74–99: Oak doors are extremely cheap per XP but slow. Many players stick with mahogany tables or switch entirely to Mahogany Homes. By now you should have the full Carpenter's outfit, a demon butler, and a well-located house. Use mobile tap-to-drop and screen markers to reduce mouse strain.

Remember that 99 Construction is a marathon, not a sprint. Even at maximum efficiency, it will take several hours of active clicking. Plan your training around other goals: do a few hundred thousand XP per session, then go PvM or do clues. The POH you are building will make those other activities more convenient, so the investment compounds.

Common Mistakes That Turn 99 Construction Into a Regret

The biggest mistake is training without a plan for materials. If you run to the bank every inventory, your XP per hour will be half of what it should be. Always use a servant or Phials, and keep your planks noted until the moment you need them. Another common error is ignoring Mahogany Homes entirely and then going broke halfway to 99. The minigame exists precisely to offer a cheaper, lower-intensity alternative. If your bank can't absorb the traditional cost, switch methods before you sell your gear in desperation.

Some players forget to set building mode correctly and waste time looking for hotspots. Always toggle building mode in House Options before you enter, or right-click the portal and enter in building mode. Also, do not forget to pay your servant: if his wage runs out, he will stop fetching planks and you will lose time. Build the servant's money bag as soon as you can and deposit a large stack of coins.

What a Bought Max Cape Actually Proves (and What It Doesn't)

When you buy a maxed account, the max cape proves that the account has reached level 99 in every skill. It does not prove that the original owner trained every skill themselves, nor does it guarantee that the account has any PvM achievements or a large bank. What it does prove is that at some point, 2,376,000 coins were spent on the cape and that all 24 skills hit 99. For a buyer, that means all the time-gated and expensive grinds are already done. You are buying back hundreds or thousands of hours of playtime.

The Construction portion of that cape is particularly valuable because it comes with a fully loaded POH — if the original owner bothered to build it. A maxed account with an ornate pool, jewellery box, portal nexus, and occult altar is worth significantly more than one with only 99 Construction and an empty house. Sellers should list these features explicitly, and buyers should verify them before paying. The gold sink it took to get there is already spent; you are just paying for the result.

Practical Next Step: From 99 Construction to Full Max

If you are still on the journey, your next move is to decide your plank budget. Calculate how many planks you need for your chosen method, check the Grand Exchange, and then either start grinding or buy the gold you need. If you are evaluating an account, open the POH and confirm the utility rooms before you commit. Either way, 99 Construction is a milestone, not the finish line. The max cape is waiting, and it costs 99,000 per skill — Construction is just one tile in that mosaic.
