Construction is an expensive skill to train. At low Construction levels, players typically make their own planks, use clay or limestone, and explore different rooms and furniture. To advance, most players use oak, teak, or mahogany planks to build and remove oak larders, driftwood prawnbrokers, or mahogany tables.

All constructed objects will always result in a loss of money, regardless if you make the planks or buy it off the Grand Exchange.

Typical costs for Construction experience vary from -5.63 (using player-made oak planks) to -19.02 coins per experience point (using mahogany planks bought from the Grand Exchange).

Items and bonusesEdit

Due to the cost of training construction, it is recommended to use bonus experience or other experience boosting items, such as the Constructor's outfit, sculpting chisel, and the clan avatar skilling boost. Players should also consider unlocking the scroll of proficiency for a chance to save a plank when using 3 or more.

Understanding experience earnedEdit

Experience gained is calculated from the experience per construction material used. The experience gained from making 2 items with 1 oak plank is the same as making one item with 2 oak planks. Therefore, it is more efficient to make items requiring more supplies, as the cost per experience is the same.

Cost of earning Construction experienceEdit

Most materials used in Construction cannot be made with skills and must be bought from suppliers or the Grand Exchange. Wooden planks are made by handing over logs and money to the sawmill operator or by using the logs in the Portable sawmill. Construction materials that can be made by the player are soft clay, molten glass, limestone bricks, and steel bars. Even these items are normally used in combination with other bought Construction materials, except for a very few, low experience items such as clay fireplaces (3 soft clay for 30 experience). Specialty items such as gold leaves, marble blocks, and magic stones can be bought from a specialty shop in Keldagrim or the Sawmill operator in the Ithell Clan District of Prifddinas.

After completing the appropriate Morytania Tasks, one may receive 30 normal planks, 20 oak planks, or 10 teak planks daily from Razmire Keelgan, potentially worth 990, 1200, or 900 construction experience respectively.

  • You can turn clay into soft clay by adding water to it. This can be done in a player-owned house using a garden or kitchen water source.
  • You can turn limestone into limestone bricks using a chisel on it. This gives 6 Crafting experience.

Special logsEdit

Special teak logs and special mahogany logs can be obtained randomly while cutting down their respective trees. These logs can be sold to a sawmill operator for 3,900 for mahogany or 1,300 for teak. If you have two of the same type, the sawmill operator will convert your inventory of logs for free in exchange for the special logs. This can be used to help reduce the cost of training Construction.


Trip timeEdit

Note: This section does not apply if the player is using Servants.

With the correct choice of teleport techniques, very little running is required to make a round trip (either two-way or three-way). This means that the total trip time is very largely dependent on how fast the player can click and select various options. To maximise the XP earned per hour depends on balancing the fastest possible round trip (i.e. least clicks) vs. a slightly slower round trip maximising the XP earned per trip. Players therefore vary in their precise technique - fast clickers tend to prefer the fastest possible trip. Players on slow computers or poor-quality internet connections tend to prefer maximising the XP per trip. Note that because of the relatively low cost of teleport compared to the cost of an inventory, the teleport trip cost tends not the be a factor in an optimised trip plan.

Plan round trip to optimise inventoryEdit

  • To maximise experience per trip, you need to maximise the number of planks / logs you transport per trip.
  • If you are using a beast of burden, you need at least one spare slot to swap logs / planks between the two inventories at the Plank Maker. A technique is to drop one or two planks to make this space and pick the planks when done. Alternatively you may decide that it is quicker to have a spare slot or two.
  • Bring materials in amounts equal to the highest multiple of the required materials to construct your items that is possible per trip (e.g., carry a multiple of 8 for larders, or 10s for Oak doors) as this reduces weight by not bringing extra material that won't be used. Alternatively, build something else to use the remaining planks (e.g. if you are carrying 26 planks, build two oak doors and then build two oak armchairs to use up the last 6 planks). With careful planning this does not need to slow down a round trip very much.
  • Making Flatpacks can be a very fast way of using up almost any "left-over" planks. For instance "Make All" Oak drawers will use up any even number of oak planks.
  • If you are three-way teleporting, always maximise your inventory of planks. Bank your unused planks and when you have enough planks, skip the sawmill teleport for a cycle.

You cannot bring a summoning familiar in your house when you're in building mode.

Experience per tripEdit

For number of planks carried. Higher numbers require a Beast of Burden.

Plank XP per item 24 28 30 44 58
Plank + Nails 29 696 812 870 1276 1682
Oak plank 60 1440 1680 1800 2640 3480
Teak plank 90 2160 2520 2700 3960 5220
Mahogany plank 140 3360 3920 4200 6160 8120


An alternative to travelling between your house and a bank is to use Servants to bring things from the bank to your house. This is faster than travelling yourself because you can build while the servant is making the trip. Better servants make the round trip faster.

Servants have a right click option that allows the fetch-from-bank menu to be brought up quickly. Furthermore, the last request is saved, so the player can repeatedly ask for the same set of items to be brought without typing the specific quantity each time.

Flatpacks Edit

Main article: Flatpack

Flatpacks are recommended as a less intensive way to train construction. Flatpacks are made in a workshop on a workbench, and can be dropped afterwards. Flatpacks can be added to the action bar to facilitate dropping.

  • Flatpacks can be sold on the Grand Exchange, however, there is very little demand for flatpacks so do not expect them to sell instantly.
  • Flatpacks can be alched, but the return is less than the cost of the runes.
  • Flatpacks may be sold to Advisor Ghrim in exchange for coins in the treasury of your kingdom, after completing the hard Fremennik Tasks. In principle he gives 10% of the material costs. How this is calculated is not clear, but the value of a flatpack is less than 10% of the GE price of a log plus the Sawmill fee. Since the Sawmill fee is fixed, this suggests that he values the logs at less than GE price but greater than the max store price.
    • Advisor Ghrim will not take noted items.
  • Flatpacks can be traded in at the Mobilising Armies activity for Investment credits. These credits are used to get reward credits which can be used to get money or other rewards. If you choose money, you can get a refund of the cost of the flatpacks.
  • Because flatpacks can be made while not in building mode, items can be dropped. This may be the most convenient way to get rid of flatpacks.
  • Flatpacks are rarely stored if using a Servant, because the return is marginal or worse given the additional cost of using a servant trip to bank them. However, if you value the flatpacks at Advisor Ghrim rates, higher value flatpacks can be worth banking. Use a BoB to accumulate enough flatpacks to make the servant journey efficient.

You need a workbench to make Flatpacks, requiring a Workshop (Level 15 Construction). Higher leveled flatpacks will require you to upgrade the workbench accordingly.

Workbench Level Required Required Materials FlatPacks Able To Build
Repair bench Repair bench 15 2 Oak Planks Broken Arrows and Broken Staves (no flatpacks)
Wooden workbench Wooden workbench 17 5 Planks, 5 Steel Nails 1-20 Furniture (Level)
Oak workbench Oak workbench 32 5 Oak Planks 1-40 Furniture (Level)
Steel framed bench Steel framed bench 46 6 Oak Planks, 4 Steel Bars 1-60 Furniture (Level)
Bench with vice Bench with vice 62 2 Oak Planks, 1 Steel Bar 1-80 Furniture (Level)
Bench with lathe icon Bench with lathe 77 2 Oak Planks, 1 Steel Bar All Furniture

Flatpack return valueEdit

The following table shows the return on an example flatback item used for training (note all items with the same plank requirements will have different GE Sell prices but the same Advisor Ghrim return). The poor return should be compared with the total loss if an item is removed or dropped.

Flatpack Planks GE Sell Price Nominal Advisor Ghrim Return Return coins/XP
Oak magic wardrobe icon Oak magic wardrobe 4 43 135.2 -0.56
Carved oak magic wardrobe icon Carved oak magic wardrobe 6 7 202.8 -0.56
Teak magic wardrobe icon Teak magic wardrobe 4 10 257.2 -0.71
Carved teak magic wardrobe icon Carved teak magic wardrobe 6 24 385.8 -0.71
Mahogany magic wardrobe icon Mahogany magic wardrobe 4 167 868 -1.81

Note: Advisor Ghrim will value slightly less than the nominal 10% value. As a snapshot, on a particular day he offered a return on some teak items that valued the teak log at 63 coins, assuming he gives full credit for the Sawmill fee. On the same day, the GE teak log price was 148 (plus 500 sawmill) and a teak plank 766, giving a real return of 9.7% or 8.2% respectively.

Recommended training methodsEdit

Level 1 to 33Edit

Skill Level: Statistics 1-33
Experience: 66 per chair
Speed: 5*****
Profit: -296,944
Requirements: None
Items required: 554 planks and 554 iron nails
At 1 to 33 Construction, one cannot have a butler, so you will have to carry the items yourself. In order to do this, you could use a ring of dueling and a house teleport tablet or simply run to the bank and back.

For the first levels of Construction you need to buy or make planks and iron nails. Start by making crude wooden chairs in your parlour and removing them, using 2 planks and 2 iron nails for each. Repeat this process until you are level 33.

Training from level 1 to 33 with this method would cost -296,944.

Level 33 to 52 or 63Edit

Skill Level: Statistics 33 - 52/63
Experience: 480 per larder
Speed: 5*****
Profit: -1,024,320
Requirements: 33 Construction
Items required: 1760 oak planks for 52 or 5840 oak planks for 63
After level 33, you can make oak larders in your Kitchen. Creating these costs 8 oak plank. It will take 1760 oak planks to go from 33 to 52 construction building oak larders and another 16,211 oak planks to get to 74 Construction. At level 40, you should go to the Servants' Guild to hire a Butler, and at level 50, upgrade to a Demon Butler. Servants can be used to bring you planks, thus speeding up your construction training. The fastest way to do this is right click the servant and select the option to fetch items from the bank. If using the Butler, you can make an average of 2.5 oak larders per round; if using the Demon Butler, you can make an average of 3.25 oak larders per round.

When making oak larders with a butler or demon butler, repeatedly request planks, then build and remove larders. With the regular butler, you can alternate 2 and 3 larders per round, whereas with the demon butler, you can build 3 larders on 2 / 3 of the rounds and 4 larders on 1 / 3 of the rounds.

It is possible to save money by not using a butler, however this greatly lowers your experience per hour.

Players should stop making oak larders at level 52 if they wish to train using mahogany planks. Mahogany tables are the second fastest construction experience in the game, but are not very commonly made because of cost. As teak planks are cheaper per experience than oak planks, you can switch to driftwood prawnbrokers at level 63.

Training from level 33 to 52 with this method would cost -1,022,574 coins.

Training from level 33 to 63 with this method would cost -3,398,880 coins.

Level 52 to 73 (Expensive method)Edit

Skill Level: Statistics 52
Experience: 840 each
Speed: 5*****
Profit: -16,537,230
Requirements: Level 52 Construction, a dining room or a Steel framed bench
Items required: 6210 mahogany planks
The second-fastest method in the game is making Mahogany tables in the Dining room, using a Demon Butler to bring you planks, building 4 tables per round, and 5 every third round. Players who are somewhat slow at building and removing tables may wish to save a bit of money by using a normal butler and building 3 tables per round and 4 every third round.

Experience per hour rates for building mahogany tables vary widely among players depending on attention and which butler is being used. A basic range of 350,000 experience to 500,000 experience an hour can be expected, with some players even exceeding 600,000 experience an hour.

Training from level 52 to 73 with this method would cost -16,537,230 coins.

Level 63 to 99 (Cheaper method) Edit

Skill Level: Statistics 63
Experience: 720
Speed: 5*****
Profit: -136,936,128
Requirements: Level 63 Construction, Aquarium
Items required: 140736 Teak Planks
The most teak planks that can be used on a single item is a driftwood prawnbroker.

A demon butler is recommended to fetch 24 teak planks in one trip from the bank. Then, four wardrobes can be flatpacked at 720 experience points each. These can then be dropped using the Action bar. This method is able to earn approximately 500,000 experience per hour.

Training from level 63 to 99 with this method would cost -136,936,128 coins.

Level 73 to 99 (Expensive method)Edit

Skill Level: Statistics 73
Experience: 1120 each
Speed: 5*****
Profit: -229,060,608
Requirements: Level 73 Construction, an aquarium room
Items required: 86016 mahogany planks
By far the most efficient way to train Construction, yielding experience rates between 650,000 and 900,000 experience per hour, is making Flotsam prawnbrokers.

The method consists of building 2 flotsam prawnbrokers, then un-certing 24 mahogany planks with a demon butler, and while the butler is away at the bank, destroying the currently built prawnbroker, rebuilding another one, and destroying it again, by which time the demon butler will have returned to give you 24 more mahogany planks. Then, 2 more are built, and the process is repeated.

Training from level 73 to 99 with this method would cost -229,060,608 coins.

Free construction experience bonusesEdit

  • Long bones and Curved bones can be turned into Barlak to get 1,500 Construction experience and 2,000 coins or 2,250 experience and 2,500 coins, respectively.
  • God Statues is a monthly Distraction and Diversion that grants Construction experience based on your level, in addition to Slayer or Prayer experience.
  • Completing daily challenges for Construction guarantees reimbursement for used planks (for most flatpack items) in the form of other items, as well as additional experience.
  • Harps in Prifddinas will give slow, but free construction experience.

Alternative methods of gaining experience Edit

Some quests grant Construction experience. See here for more details.
