Over the Top DIY: 16 Backyard and Home Builds That Went Way Further Than Anyone Needed
Over the top DIY is what happens when a simple weekend project gets a little out of hand, in the best possible way. Someone sets out to build a sandbox and ends up with a full pirate ship. Someone wants a bookshelf and adds a secret door. We love these builds because they are pure joy. Nobody needed them, yet everyone who sees them grins from ear to ear. Most of them started with scrap wood, a few tools and a big dream. Below are 16 backyard and home builds that went way further than anyone asked for, along with simple ways to try a smaller version yourself. Some are weekend projects, others take a whole summer. All of them will make you look at your own yard a little differently..
Over the Top DIY Pirate Ship Playhouse
A plain playhouse would have been enough, but some parents go all the way and build a full pirate ship. A curved hull, a tall mast with canvas sails, a rope ladder and a slide off the side turn the backyard into the high seas. Kids spend hours on lookout duty, and the neighbors stop to take photos. You can start smaller with a flat ship shaped sandbox and add a mast later. Would your kids rather be the captain or the lookout..

Bookshelf Secret Door
Who has not dreamed of pulling one book and watching a wall swing open? A bookshelf secret door makes that dream real, and it is a favorite over the top DIY for book lovers. It is usually built on heavy duty hinges or a pivot, with a real shelf unit filled with books. Behind it can be a reading nook, a pantry or a quiet home office.

Homemade Arcade Cabinet
Grown ups who loved the arcade as kids are now building their own cabinets in the garage. A simple plywood shell, a flat screen, a joystick and a handful of bright buttons bring the whole thing to life. Paint it a bold color and it becomes the coolest over the top DIY piece in the house. It is a great project for a parent and teen to build together over a few weekends. Would you paint yours a bright color or classic black?

Greenhouse Built From Old Windows
Old windows from yard sales and salvage yards can become the most charming greenhouse on the block. Each frame is a little different, which gives it a patchwork cottage look. Plants love the sunlight, and you get a cozy spot to start seeds in spring. It does take time to collect enough windows, so many builders gather them for a year or two. Ask neighbors who are replacing windows, since many are glad to give them away. Could you picture one in your garden?

Over the Top DIY Basement Movie Theater
Why go out to the movies when the basement can be a theater? Builders add a wooden riser so the back row can see, a big projector screen and dark walls that make the picture pop. Star lights in the ceiling and a little popcorn cart finish the feeling. Even a simple version with a projector and blackout curtains makes family movie night feel special.

Giant Family Size Chair
One builder decided a regular chair was too small and made one three times the size. The result is a giant backyard chair the whole family can climb into for a photo.

Sailboat Bed for Kids
Bedtime is easier when the bed is a sailboat. This build wraps a simple twin bed frame with a curved hull, porthole style drawers and a small cloth sail over the headboard.

Over the Top DIY Backyard Observatory
Some stargazers build a whole observatory behind the house. A small round shed with a rotating dome and an opening slot protects the telescope and makes clear nights easy to enjoy. It looks like something from a science museum, yet many are built from plywood and metal sheeting. Kids who grow up with one often fall in love with the night sky.

Treehouse With a Slide
The classic treehouse gets an over the top DIY upgrade when you add a slide. Climbing up is half the fun, and zooming down is the other half. Many families build on a set of posts beside the tree rather than on the trunk itself, which is safer for both the tree and the kids. Add railings all around and a little roof for rainy days. It is the kind of build kids remember for the rest of their lives. What would you name yours?

Over the Top DIY Train Table That Rises to the Ceiling
