Building a Stronghold

A character can spend time between adventures building a stronghold. Before work can begin, the character must acquire a plot of land. If the estate lies within a kingdom or similar domain, the character will need a royal charter (a legal document granting permission to oversee the estate in the name of the crown), a land grant (a legal document bequeathing custody of the land to the character for as long as he or she remains loyal to the crown), or a deed (a legal document that serves as proof of ownership). Land can also be acquired by inheritance or other means. Royal charters and land grants are usually given by the crown as a reward for faithful service, although they can also be bought. Deeds can be bought or inherited. A small estate might sell for as little as 100 gp or as much as 1,000 gp. A large estate might cost 5,000 gp or more, if it can be bought at all. Once the estate is secured, a character needs access to building materials and laborers. The Building a Stronghold table shows the cost of building the stronghold (including materials and labor) and the amount of time it takes, provided that the character is using downtime to oversee construction. Work can continue while the character is away, but each day the character is away adds 3 days to the construction time.

Stronghold	Construction Cost	Construction Time
Abbey	50,000 gp	400 days
Guildhall, town or city	5,000 gp	60 days
Keep or small castle	50,000 gp	400 days
Noble estate with manor	25,000 gp	150 days
Outpost or fort	15,000 gp	100 days
Palace or large castle	500,000 gp	1,200 days
Temple	50,000 gp	400 days
Tower, fortified	15,000 gp	100 days
Trading post	5,000 gp	60 days

Additionally, we are using the resources at Thieves Guild Strongholds to build and hire staff. If changes are made, I will put the notifications and what not here. If any contradiction occurs notify the DM. To make changes easy for this wiki, I will copy the current charts below and make any changes I want there...

Premade Structures

Interested in purchasing an existing stronghold, or building one from scratch? This section provides a guideline that DMs can use to help a party with their stronghold needs. The DM can choose to build a new structure, using rooms and stronghold parts, or they can choose a preexisting template, structure or cluster of rooms (see the table below). In addition, you can find staff for your stronghold, their monthly wages and their appropriate equipment. This page provides example stronghold structures, using a collection of sub-structures and rooms (or stronghold "parts"), grouped together and given a single price for your convenience. You can use these examples to quickly create a stronghold for use in your game. Maintenance & Wages: For simplification (since D&D is more about adventuring, than management), it is best to keep expenses simple. Most DMs choose only use staff wages in monthly maintenance. And, if the player(s) decide to rent, adding in rental costs. However, some DMs may wish to add taxes for owned properties (recommended: 0.2% of the building cost per month; more in large cities and evil kingdoms). For businesses, a DM may wish to roll for business profits/loses every time the players return. Building Materials: Most aboveground structures are built using wood, and underground rooms are built using hewn stone. You can choose to change the material using the dropdowns below (for a list of wall materials and their pricing, see our stronghold walls. Adventure Hooks: Strongholds are great a source for adventuring ideas. Mansions can be raided, robbed or siezed by the ruling class. They can be overrun by monsters or vermin, or be inhabited by cultists or bandits while the adventurers are away. Businessness may need the adventurer's help to avoid calamity and ruin.

† Monthly wages do not include staff gear (which must be purchased separately). Monthly wages do not include any business expenses or inventory as it is assumed that most businesses are self-sufficient. However, a DM may wish to roll for profits/losses for a business every so often. Note: Building over 2 stories have additional costs, as described in the stronghold parts section. Some structures, such as the wizard tower and guard tower have additional fees for being 3 stories tall.

Room-by-Room

This page is useful for building a stronghold room-by-room, or for adding rooms to an existing structure. Below are the various rooms and components. The choice of components dictates the purpose of the stronghold, whether it's a palatial home, military fortress, or arcane nexus. Many of these components are individual rooms, but some may be combined to build larger structures (for example, the Basic Tavern is about 400 square feet and can seat around 15 people ... but two units can be combined to produce an 800 square foot tavern seating 30 people; and the tavern can be made more serviceable by adding a kitchen and additional storage area). Walls: Structures above ground are constructed with wooden walls by default, at no extra cost. Below ground walls are made of hewn stone at no extra cost. If other materials are used, additional fees can be incurred. You can select alternative materials from the cost modifiers below. More wall details can be found on our walls page. Build Time: Building a stronghold takes one week per 10,000 gp of total price (if materials and laborers are readily available). Optional Rule: For every 10% extra that is spent, it takes 10% less time to build, up to a maximum of a 70% "rush charge" to get the castle built in 30% of the usual time. The DM may rule that some strongholds shouldn't use this optional rule. For instance, if your stronghold price includes a large percentage of wondrous architecture, you might choose to construct such items separately.

Basic units of measurement in DnD are based on creature size — a 5ft square can hold a Medium-sized creature. Below is a small chart showing basic units of measurement converted into square feet (with a square room's dimensions). Note: a 40'x40' room occupies the same square feet as a 20'x80' room, so a "square" doesn't need to be used when building.

Square Feet	Square Room (ft)	Square Room (5ft squares)
400 sq. ft.	20' x 20'	4x4 5' squares
625 sq. ft.	25' x 25'	5x5 5' squares
900 sq. ft.	30' x 30'	6x6 5' squares
1,225 sq. ft.	35' x 35'	7x7 5' squares

Walls

This page details stronghold and dungeon walls. Information includes thickness, hit points, damage threshhold and costs to build. Structural Walls vs. Freestanding Walls: Structural walls are those that make up building, and can have different material on both the interior and exterior side. Freestanding walls are strong, protective walls that usually surround large cities, castles and courtyards. Damage Threshhold: Certain wall materials have a Damage Threshhold. A wall with a Damage Threshold has immunity to all damage unless it takes an amount of damage from a single Attack or Effect equal to or greater than its Damage Threshold, in which case it takes damage as normal. For example: if a wall has a damage threshhold of 20, and is attacked for 17 damage, no damage is taken (since 17 is less than 20). However, if the same wall is attacked with 24 damage, it takes 24 damage (since 24 is greater than 20). Augmenting Walls: Once a wall is built, it is possible to augment the walls. You can add razor wire, make the walls slippery or even add magical properties. For a list of augmentations, click here.

Structural Walls

Structural walls are those that make up a building, such as a cottage or mansion. When above ground, structural walls can use different materials on the interior an exterior side of the wall, but many use the same material on both. Structural walls are different from freestanding walls, which are walls that surround areas (like the walls surrounding a city, castle, or courtward). For more information on freestanding walls, click here.

* Freestanding walls, like those that surround castles and keeps, are thicker, have more hit points and cost more. See the freestanding wall table below. There is a great Calculate Structure Wall Costs Calculator on the TG.cc site.

Freestanding Walls

Freestanding walls are thick, protective walls that tend to surround cities, castles and courtyards. They are different from structural walls that make up buildings because they are thicker, stronger, cost more and can be built extremely high (For more information on structural walls, click here). Freestanding walls that are higher than 10 feet must add an extra layer of thickness to each lower layer in the stack. This addition is cumulative; For example, a 10ft tall wall will have a single panel (see thickness in the table below). A 20ft tall wall would have 2 thick panels, topped by a single panel. A 30ft tall wall would have 3 panels, topped by 2 panels, topped by a single panel. Etc.

Wall Augmentation

Once a wall is built, the walls may be augmented for an additional cost. The costs below are for each 5-foot wide by 10-foot tall wall section that is augmented. The augmentation effect also applies to any doors, windows, or other accessways through that wall. You can choose not to augement such entryways, though their area still counts toward the augmentation's area of effect (i.e. a non-augmented doorway next to a wall with a poisonous fog veil will have a poisonous fog in its path). Some magical augmentation is extremely powerful — so powerful that a DM may decide that the base costs are not enough. In such a situation, the DM may decide that a quest is required before the augmentation can be applied. For example, before a wizard can begin to add a fog veil to a stronghold wall, they may need the party to retrieve an eversmoking bottle. Or, if the party wants a fiery wall, they may need to retrieve some rare spell components from the elemental plane of fire.

Augmentation	Cost per 5'	Notes
Airtight	30 gp	Prevents gases from passing through (but not over or around).
Ethereal Ward	100 gp	Protects against ethereal intrusion.
Fiery	3,000 gp	The wall is continually ablaze with magical fire.
Fireproof	25 gp	The wall is impervious to fire.

Fog Veil, Solid	1,000 gp	Conceals the wall with a thick veil of fog that is difficult to move through.
Fog Veil, Stinking	2,000 gp	Conceals the wall with a stinking veil of yellow fog.
Frostwall	400 gp	A cold wall that causes frost damages to anyone passing through a broken portion.
Greased (Slippery)	5 gp	This wall is slippery and difficult to climb.
Magic Warding	500 gp	The wall has resistance to any damage caused by magic.
