Moonlight Peaks House Upgrade Guide

Quick answer: ask Ridge at Howling Hammer to expand your house. The first house upgrade costs 8,000 Coins, 100 Wood, and 25 Stone and adds another room. TheGamer and Eurogamer independently publish the same price and result.

Ridge can work on only one construction project at a time. Finish or wait for any active Barn, Mill, Well, or other building job before trying to start the house expansion.

First House Upgrade Cost

Upgrade	Coins	Wood	Stone	Confirmed result
First house expansion	8,000	100	25	Adds one room

This is the only house-upgrade cost corroborated by two complete post-launch guides at the time of this review. Eurogamer confirms that later expansions become more expensive, but the checked article does not publish their exact material tables. Do not plan later upgrades around unsourced cost lists copied from search summaries or forum comments; use the price Ridge shows in the current game build.

Where to Upgrade the House

Go to Howling Hammer, the construction shop at the upper-left side of the town square, and speak to Ridge at the counter. Choose the house-upgrade option, then confirm the project after the cost is displayed.

TheGamer's current shop guide lists Howling Hammer as open on weekdays from 6 PM to midnight. If Ridge is present but the construction choice is unavailable, check whether another project is already in progress.

How to Expand Your House

Save 8,000 Coins.
Gather 100 Wood and 25 Stone.
Finish any construction job Ridge is already handling.
Visit Ridge at Howling Hammer during shop hours.
Select the house-upgrade option and verify the displayed cost.
Hand over the payment and let Ridge begin construction.
Return after the completion time shown by the game and enter the house to see the additional room.

Bonus Action reports that a house expansion takes about one day and begins after the request. Treat the delivery estimate shown in Ridge's menu as the authority if a patch or an overlapping project changes that timing.

What to Prepare Before Ordering

Keep the materials available

Two major guides agree on the first price. A third guide says the required goods must be in your bag. Because crafting normally pulls from universal house storage, this is easy to overlook: if Ridge does not accept the project, move the 100 Wood and 25 Stone into your carried inventory and try again.

Clear the farmhouse perimeter

Bonus Action also advises clearing enough outdoor room for the expansion. Remove movable objects close to the farmhouse before ordering. Do not destroy crops or permanent resources solely on this report; start with furniture, makers, paths, and other objects that can safely be moved.

Finish the more urgent Ridge project first

Ridge's one-project limit applies while the house is being expanded. If you urgently need a Barn for Luna's animal quest, a Well for a larger field, or another progression building, order that first. The house upgrade gives indoor space, but it does not replace a farm building.

Is the House Upgrade Worth It?

The first expansion is most useful when crafting stations, storage furniture, and decorations are competing for the same floor space. It adds a room rather than an inventory row or a larger Barn.

Prioritize it when:

the starter room is obstructing crafting or decoration;
8,000 Coins will not delay a story-required building;
no urgent Ridge project is waiting;
you already have the Wood and Stone without emptying your early crafting supply.

Delay it when the same Coins are still needed for a quest building, tool progression, or the processing chain that produces income. The Money Guide explains how to build the 8,000-Coin fund, while the Farming Guide covers Barns, Wells, makers, and building movement.

House Expansion vs. Other Upgrades

Purchase	What it changes	Where to get it
House expansion	Adds indoor room space	Ridge at Howling Hammer
Inventory upgrade	Adds carried bag slots	Sabrina at Webb of Wonders
Barn	Houses farm creatures	Ridge after Luna's livestock progression
Tool upgrade	Improves a specific tool tier	Ridge with the current tool, Bars, and Coins
Building movement	Repositions major farm structures	Hoisthaven spell, then use it on the building

Buying a bag upgrade does not enlarge the farmhouse, and expanding the house does not increase Barn capacity. Choose the upgrade that matches the actual bottleneck.

If the House Upgrade Option Is Missing

Check these in order:

Visit during Howling Hammer's weekday shop hours.
Talk to Ridge from the customer side of the counter.
Wait for any active Ridge construction project to finish.
Put 8,000 Coins, 100 Wood, and 25 Stone together in the carried inventory.
Move furniture or machines away from the farmhouse perimeter.
Advance the current roof, town, and farm-building objectives if your save is still in the opening quests.
Recheck Ridge's displayed requirement after a game update instead of assuming the launch cost is permanent.
