A great way to build a house with reasonable dimensions and expectations while getting ideas for inspiration is to browse Zillow for houses in the desired region. Use filters for price, home type, and similar specs to get a realistic picture of lot size and living space.

When viewing a property (for sale or existing) the number atop the lists the square footage of the house. To obtain the lot size; scroll down to the "Facts and Features" section as pictured below.

Some real estate agents will also provide the floor plans or city zoning breakdowns amongst the images. With this in mind, it's much easier to set realistic expectations for a new house in a similar neighborhood.

At time of writing; it is impossible to "dig" beneath the map as one would commonly assume necessary for building a basement. Instead, for lack of a simple description, you must build a standard room (which will become the basement) and then "bury" it via 1 of 2 methods:

This is the same method demonstrated, confusingly, in this guide[en.homedesign3d.net]. Below are steps which are more simple.

1. Build a room on the initial ground which will become your basement.
   
2. Add a staircase to the basement.
   
3. Surround this basement room with other, empty, rooms.
   [3A] If you wish to have basement windows you will need to lower the height of the surrounding rooms to the required level. This can be done in "Aerial" mode.
   
4. Go "Up" one level so as to see the ceilings of all rooms. Use the "Textures" tool to paint the tops of the non-basement rooms grass green.

This method is slightly easier for standard and simple houses but will not support building into hillsides, protruding basement windows and makes porches more difficult. The benefit of this method is the ability to properly size the lot and represent the land space above.

1. Build a room on the initial ground which will become your basement.
   
2. Add a staircase to the basement.
   
3. In "2D" view go "Up" one level. This should be the level above the newly formed basement.
   
4. Add land to the desired size / cover the entire buildable map.

* It may be necessary to lower the height of the basement walls (done via "Aerial" mode) a small amount for the stairs to blend properly.

This process is similar to the "Room Crowding" method described in the "How To Build A Basement" section of this guide. The general idea is to build a room on the default ground and surround it with empty rooms which descend away.

To demonstrate an exposed basement observe the images of this "Hobbit Hole" style house below:

⠀
Each of the empty rooms has a height descending at a rate of 3" per room.

This is a tedious process but does imitate a hillside. Although this demo has single-row hills per step, you can can have each column with multiple rows to represent uneven and dynamic hills.

Reminder: These dimensions are based on US standards in the approximate Midwest region. 'Living Space' assumes the 2020 Census[www.census.gov] average single-family house size.

HD3D allows custom images to be imported into the game via the Textures > Imported textures menu. There are a number of common household goods which do not have a proper in-game model. Such items may include various plants, safes, and utilities. Many of these models can be supplemented via texture images.

• HD3D supports transparent .png images.
  
• Standard image size is 512x512 px.

Images greater than 512x512 will become distorted or cropped. Images significantly smaller may wrap improperly.

Below is a small assortment of usable images:
