Fields of Mistria House Upgrades Guide
Plan every Fields of Mistria house upgrade with costs, materials, room sizes, and the farmhouse features you keep from day one.
Fields of Mistria house upgrades do more than make the farmhouse look larger. They change the amount of usable indoor space, add rooms that can take pressure off a crowded main room, and eventually create a whole second floor. This guide lists the four upgrades in order, the resources to set aside, and a simple way to decide when a bigger house helps your farm plan.
What your farmhouse already does
Before buying an upgrade, the starting farmhouse already covers four important daily jobs. The worn bed ends the day and saves the game at day-end. The diary lets you save without going to bed, which is useful before a risky mine trip or a long decorating session. The Farm House Calendar shows the date plus special events, including festivals and villagers’ birthdays.
There is also a Basic Wood Chest for overflow storage. That is more useful than it first appears: items stored in a chest can be made available to Woodcrafting, Cooking, or Blacksmithing when the chest-pull setting is enabled. Keep the chest close to the indoor work area if you regularly use the house for recipes, rather than treating it as disposable starter furniture.
These basics remain useful through every upgrade. A larger home gives you more places to arrange storage and furnishings; it does not replace the bed, diary, calendar, or chest with a different system. Start by protecting a clear route from the entrance to the bed and diary. It keeps the house convenient on rushed days, even after the rooms become more decorative.
How house upgrades work
Buy farmhouse improvements from The Carpenter’s Home Upgrade option. Each tier has a fixed tesserae price and a material delivery. Once you meet the previous tier’s requirement, the upgrade applies immediately; there is no multi-day construction wait to plan around.
The first three tiers are a straight sequence. The fourth has an additional story-progress gate: The Carpenter’s Shop must be upgraded before the final home upgrade can be purchased. That makes it worth holding the final materials in reserve rather than assuming that having the money alone will finish the project.
The total cash cost for all four Fields of Mistria house upgrades is 95,000t. The first three tiers need 1,500 Wood, 1,500 Stone, and the relevant ingots; the final tier switches to refined materials. Planning those totals early prevents a house goal from consuming the stockpile intended for farm buildings or crafting.
Home Upgrade 1: enlarge the main room
The first upgrade costs 5,000t, 500 Wood, and 500 Stone. It has no prior upgrade requirement. The original room grows from 13 × 8 tiles to 17 × 12 tiles, turning the same single-room home into a much more flexible space.
This is the most practical early upgrade if furniture, chests, and utility items have begun to block one another. It adds room around the existing living space instead of adding a separate wing, so it is ideal for creating zones: put storage and work-adjacent pieces on one side, preserve a sleep-and-save corner, and leave an open central path.
For farm layout purposes, Upgrade 1 is usually a better first indoor investment than filling the starting room with furniture. The larger footprint gives future items somewhere to go without forcing the entrance, bed, or diary into an awkward corner.
Home Upgrade 2: add a left room
Home Upgrade 2 costs 15,000t, 500 Wood, 500 Stone, and 20 Iron Ingots. It requires Home Upgrade 1. The enlarged original room does not grow again; instead, a new 13 × 9 room is added on the left side.
Treat this as a purpose-built room, not merely overflow. A useful division is to leave the original room as the everyday entry and utility space, then use the left room for decoration, collections, spare beds, or a themed storage area. The point is to keep frequently used furniture near the entrance and move low-frequency items out of the daily route.
The iron requirement is the first sign that house upgrades compete with tool and crafting progression. Do not convert all of your ore into ingots automatically. Check the planned upgrade, keep the required 20 Iron Ingots, and then spend the remainder on your other projects. With its 15,000t price, Upgrade 2 is most satisfying when you already know what the added room will solve.
Home Upgrade 3: add a right room
Home Upgrade 3 costs 25,000t, 500 Wood, 500 Stone, and 20 Silver Ingots. It opens after Home Upgrade 2 and places another 13 × 9 room on the right. Neither the central room nor the left room changes size.
At this stage, the first floor has a central 17 × 12 room with matching side rooms. That is enough space to give each room one job. For example, keep the center as a clean arrival room with the bed, diary, calendar, and a selected chest; assign the left room to storage and practical furnishings; make the right room a living, display, or guest area. The exact theme is optional, but the separation keeps daily actions fast.
Silver Ingots are the limiting material to watch here. If you have 25,000t but are still mining toward the 20-ingot target, wait to redesign the room layout until the upgrade is actually available. Building a furniture plan around a doorway that does not exist yet creates needless rearranging later.
Home Upgrade 4: add a second story
The final upgrade costs 50,000t, 200 Hard Wood, 100 Refined Stone, and 30 Gold Ingots. It requires Home Upgrade 3 and an upgraded Carpenter’s Shop. In return, it adds an entire second floor with three new rooms matching the dimensions of the first-floor rooms: one 17 × 12 room and two 13 × 9 rooms.
Access upstairs with a ladder, stairs, or a teleportation pad. Plan that access point before you fill the central first-floor room; an attractive arrangement is not very useful if the route to half the house is obstructed. The second story is best for items you enjoy seeing but do not interact with every morning: themed furniture sets, collections, extra bedrooms, or seasonal displays. Keep emergency storage and everyday saving tools downstairs.

Fully upgrading also matters beyond floor space. In the current 1.0 release, a completely upgraded house can have its exterior customized at The Carpenter’s Shop. This is a cosmetic finish to schedule after the four upgrade costs, not a substitute for the materials and progress needed to reach the final tier.

A sensible upgrade order for a working farm
There is no penalty for delaying a house upgrade, so use the sequence to support the farm you are actually building. Upgrade 1 is a strong choice once your starter room makes daily movement annoying. Upgrade 2 and Upgrade 3 become worthwhile when you can name a real use for their side rooms, rather than just because the next tier is available.
Save Upgrade 4 for the point where 50,000t, Hard Wood, Refined Stone, and Gold Ingots will not stall a more urgent goal. It is a major amount of space, but it is also the only tier tied to the Carpenter’s Shop progression. Put a reminder in the in-game calendar or your own plan to revisit it after that shop upgrade is complete.
The practical rule is simple: buy space when it shortens your routine or lets you separate a real function. Keep the central room readable, group storage deliberately, and use side rooms and the second floor for the parts of home design that should not slow down a farming day.
Quick answers
Do house upgrades take several days? No. Once purchased at The Carpenter with the required materials, each farmhouse upgrade takes effect immediately.
What changes on each tier? Upgrade 1 enlarges the original room. Upgrades 2 and 3 add one 13 × 9 room on the left and right respectively. Upgrade 4 adds a second floor with three rooms sized like the first floor.
Do I lose the bed, diary, calendar, or chest after upgrading? No. Those starting features remain part of the farmhouse; more room simply makes it easier to organize the functions around them.
What blocks the final upgrade? You need Home Upgrade 3, 50,000t, 200 Hard Wood, 100 Refined Stone, 30 Gold Ingots, and an upgraded Carpenter’s Shop.
