Starting your life in Pelican Town begins in a modest one-room shack, but the progression of your farm is tied directly to the expansion of your living space. The farmhouse is not just a place to sleep; it serves as a gateway to essential game mechanics like cooking, marriage, raising children, and endgame artisan profit. With the significant changes introduced in the 1.6 update, understanding the costs and benefits of each Stardew Valley house upgrade is vital for efficient farm management.

All structural changes are handled by Robin at the Carpenter's Shop. Located in the mountains north of town, her shop is open most days from 9 AM to 5 PM. Before committing to an upgrade, you must ensure you have both the liquid gold and the raw materials required, as Robin will be occupied on your farm for three consecutive days per upgrade, during which she cannot process other building orders.

The First Upgrade: Unlocking Cooking and Marriage

The initial expansion transforms your starter cabin into a functional home. This is arguably the most impactful jump in the game because it removes the "single room" limitation and introduces the kitchen.

Requirements and Costs

  • Gold: 10,000g
  • Wood: 450 pieces

Key Features

Once Robin completes the three-day construction, your house gains a kitchen and a dedicated bedroom. The bed is upgraded from a single to a double bed, which is a mandatory prerequisite for marriage. You cannot propose to a candidate with a Mermaid's Pendant unless this upgrade is complete.

The kitchen features a stove for cooking recipes and a refrigerator. The fridge acts as a unique storage chest with 36 slots. Its primary advantage is that any ingredients stored inside are automatically available when you interact with the stove, allowing you to craft complex dishes without carrying every item in your personal inventory. Additionally, the kitchen sink functions as a permanent water source for refilling your watering can, saving a trip to the farm pond.

The Second Upgrade: Expanding the Footprint

The second major renovation focuses on family life and increased floor space. In the 1.6 version of the game, the requirements for this upgrade were adjusted to better balance the mid-game economy.

Requirements and Costs

  • Gold: 65,000g
  • Hardwood: 100 pieces

Key Features

This upgrade adds two new rooms: a nursery with a crib and two single beds, and a large empty room that can be used for storage or decoration. The existing kitchen and bedroom also receive a slight increase in square footage.

Having the nursery allows you and your spouse to have or adopt children. Beyond the social aspect, this upgrade is the trigger that unlocks "Renovations" at Robin’s shop. Once this stage is reached, you can also paint the exterior of your house, allowing for a customized look that matches your farm's aesthetic.

The Final Upgrade: The Cellar and Artisan Profits

While the previous tiers focused on lifestyle and family, the third upgrade is purely economic. It does not add any rooms to the main floor but instead digs out a basement beneath the kitchen.

Requirements and Costs

  • Gold: 100,000g
  • Materials: None

Key Features

The cellar is the only location where Casks can be used. These specialty machines allow you to age artisan goods—specifically wine, cheese, goat cheese, beer, mead, and pale ale—to increase their quality level. Products can reach silver, gold, and eventually iridium quality, which doubles the base selling price.

Robin provides 33 casks upon completion, but the cellar's footprint can hold up to 189 casks if you optimize the layout. For players focused on high-profit margins, aging Starfruit or Ancient Fruit wine in the cellar is the most effective way to generate millions of gold in the late game. It is a slow process (56 days for wine to reach iridium), but the return on investment is unmatched.

Modern Renovations in Version 1.6

Once you have completed the second house upgrade, you gain access to a variety of internal renovations. Unlike the main tiers, these are often modular. While some were free in previous versions, most now require a gold investment, reflecting the added value they bring to house customization.

Available Layout Changes

  • The Attic (60,000g): Adds a large room at the top of the house. It provides significant extra space for chests, kegs, or elaborate dioramas.
  • Dining Room (150,000g): A premium expansion that adds a dedicated large room for hosting or displaying furniture catalogs.
  • Expanded Corner Room (100,000g): Significantly increases the size of the room located in the top-right corner of the floor plan.
  • Cubby (10,000g): Adds a small, cozy nook perfect for a library or a specialized storage corner.
  • Southern Room (30,000g): Extends the house downward, creating a new area below the main living space.
  • Open Bedroom (10,000g): Removes the partition between the hallway and the bedroom for a more open-concept feel.
  • Remove Crib (Free): If you do not plan on having children, Robin can remove the crib to give you more floor space in the nursery. This can be undone later for free if you change your mind.

These renovations are completed instantly, which is a major convenience compared to the three-day wait for primary upgrades. If you decide a renovation doesn't fit your needs, Robin offers a full refund upon removal, provided the space is cleared of all furniture and items.

Customizing Your Spouse Room and Roommate Space

Marriage or moving in a roommate like Krobus brings a unique addition to the farmhouse. A specialized "Spouse Room" will appear to the right of the main bedroom. The decor of this room is fixed based on the character's personality. For example, Abigail’s room features a drum set and a pet guinea pig, while Harvey’s room functions as a small radio clinic.

While you cannot change the wallpaper or flooring within the spouse room itself, you can place furniture and decorative items around the entrance to blend it into your overall house design. If you divorce or ask a roommate to leave, this room is removed immediately, and the space is reverted to a standard wall.

Strategic Timing for Upgrades

Deciding when to spend your hard-earned gold on a Stardew Valley house upgrade depends on your playstyle.

Early Game Strategy: Aim for the first upgrade by the end of Spring or early Summer of Year 1. The ability to cook is vital for mining and fishing. Meals like Roots Platter or Algae Soup provide energy and health buffs that allow you to stay in the mines longer. Furthermore, starting the marriage process early ensures you have help on the farm (watering crops or feeding animals) by the time you reach the busy Fall season.

Mid-Game Strategy: The second upgrade is often a lower priority unless you are eager to start a family or need the extra space for storage. Hardwood can be a bottleneck early on; ensure you have upgraded your axe to at least Steel to harvest stumps in the Secret Woods before attempting this upgrade.

Late Game Strategy: The cellar should be purchased as soon as you have a steady supply of wine or cheese. It is a passive income generator. If you have 100,000g sitting in the bank, the cellar will pay for itself within one or two cycles of iridium wine production.

Exterior Customization and Moving Your Home

Robin also offers services that don't involve adding rooms but change how your house interacts with the farm layout.

Painting the House

Once you have the second upgrade, you can select "Paint Buildings" at the Carpenter's Shop. You can individually customize the roof, siding, and trim of the farmhouse. This feature is free and allows you to coordinate your home with your barns, sheds, and coops.

Relocating the Farmhouse

One of the most powerful tools for farm organization is the ability to move the farmhouse. By selecting the "Move Buildings" icon at Robin's shop, you can pick up your entire house and place it anywhere on your farm, provided the footprint (9x5 tiles) is clear of debris, crops, or other structures. This allows you to redesign your farm layout without being stuck with the default house placement.

Tips for Interior Design

Upgrading the house provides the canvas, but the decoration makes it a home. To maximize the utility of your new rooms, consider the following:

  1. The Furniture Catalogue: Sold by Robin for 200,000g, this item provides unlimited access to almost every piece of furniture in the game for free once purchased. It is a massive upfront cost but essential for anyone planning to utilize the new 1.6 renovation rooms.
  2. Lighting Matters: Standard windows provide natural light during the day, but at night, the farmhouse can be dark. Use the furniture catalog to experiment with wall sconces and floor lamps to highlight different zones in the open-concept layouts.
  3. Wallpaper and Flooring: Each room in the upgraded house can have its own unique wallpaper and flooring. This includes the small hallways and connectors. Use different textures to visually separate the kitchen from the living area.
  4. The Workbench: Place a Workbench in your new empty room or the corner room. If you surround it with chests containing wood, stone, and ores, you can craft items using materials directly from those chests, turning one of your upgrades into a centralized crafting hub.

Upgrading your farmhouse in Stardew Valley is a journey of turning a survival shack into a luxury estate. Whether you are aiming for the 150,000g dining room to show off your wealth or the strategic cellar to double your wine profits, each step with Robin brings new depth to your farming life. Plan your resources carefully, keep an eye on the 1.6 renovation costs, and build a space that reflects your journey through Pelican Town.
