How to Build a House Out of LEGOs

Updated July 20, 2017

There are many things you can build using LEGOs, from works of art to pirate ships. But many of these items are time-consuming and require enormous amounts of LEGOs. This tutorial is for a simple house built from LEGOs, complete with interior walls that can be expanded upon at your leisure.

Place double-row LEGO bricks in a rectangular pattern. You can create as large a house as your LEGOs will allow. Make sure you leave a space for the door. You can place the door wherever you choose, but it's best to have it on a long side. Make sure you keep the sides of the doorway straight; you don't want an uneven doorway. Don't make the doorway wider than your longest double-row LEGO. You'll need a single piece to cap the doorway later.

Place bricks until you have two to three rows at least. Now you can leave a spot for a window. To simplify it for this tutorial, place the window opposite the door and remember the same rules apply to windows as to doorways. As with the door, don't make the window too wide. You should have the lower portion of a house now.

Continue placing LEGOs until you're satisfied with the height of the door and window. If you prefer, you can cap the window and continue up a little bit before capping the door. To cap them, place a LEGO brick over the top of the opening longer than the opening is wide.

Add a minimum of two more rows of bricks above the top of the doorway all the way around. At this point, you should have an exterior of a house complete with doorway and window, minus a roof and interior walls. Your top row should be level all the way around.

Create interior walls using the single-row LEGO bricks. These can be created however you choose, but don't go higher than the exterior walls. Apply the same steps for creating and capping doors as with exterior walls. Upon completing this step, you should have a house complete with interior walls without a roof.

Create gable ends by continuing your LEGO exterior walls up on the short ends of the house. Shorten each row by two connectors that are on top of the LEGOs. It should leave two of the raised circles at each end of each row. Continue up (shortening each row) until you have one brick with four connectors on top at the top of the gable.

Begin creating the sloped roof by placing a double-row LEGO at a corner on the exterior walls. Place it so that one end of it hangs just over the end of the each wall by one row on the outside edge of the wall. Continue down the long side of the house until you accomplish the same thing on the other end. Repeat this step on the opposite side. You should now have an eave created on the long sides of the house.

Place the next row of LEGOs on the roof so that one row of the LEGO sits on the previous row and one sits on the gable end. Continue the row all the way to the end. Remember to leave an overhang for the eave on the gable ends.

Switch to the opposite side and repeat the process for creating the sloped roof. Alternate sides on each row until you reach the top. Your roof peak should be a single line of double-row bricks. Your house is complete.


Cap your interior walls with a flat, large LEGO base to create an attic Create a doll house with a removable roof . Glue together all walls until you have the interior walls and exterior walls minus the roof and gables. Add the first row of the roof and gables and glue the rest of the roof and gables together, making sure you have an unglued layer separating the walls from the roof and gables.


Always monitor small children when playing with LEGOS, which are a possible choking hazard for children and pets. Do not leave LEGOS on a floor where people walk without shoes. They can hurt when stepped on.
