Looking for a clever way to add storage without sacrificing floor space? A bridge bookshelf that frames a doorway is the perfect DIY solution. It turns an often-overlooked wall into a functional and stylish feature, ideal for hallways, entrances, or living rooms. This simple project uses slim materials to minimize bulk while providing ample room for books of all sizes. The top section is slightly shorter to make the most of high ceilings, and the front frame is crafted from multiplex panels for a clean, durable finish. Let's walk through how to build your own.
What You'll Need for This Project

Before you start, gather the following materials and tools. For a cohesive look, consider pairing your new bookshelf with other home improvement essentials to refresh your space.
Materials
- 12 mm thick MDF: 2+2 back panels and inner sides (242/100 mm x height of door frame top plus 242 mm), 18 small shelves (100×230 mm), 1+1 back and top shelf (242/100 mm x external width of door frame).
- 12 mm thick beech or birch multiplex: 2 side frame elements (same size as back panels), 1 top frame element (242 mm x external width of door frame plus 484 mm).
- Miscellaneous: Vinyl glue, expansion plugs, clear varnish.
Tools
- Table circular saw
- Clamps
- Drill
- Finishing tools

Step-by-Step Construction
1. Measure and Cut
Start by measuring the door frame. Cut the MDF and multiplex pieces according to the dimensions listed above. Precise cuts are crucial for a snug fit, so use a table saw for accuracy.
2. Assemble the Shelves
Glue the inner sides and back panels together. Attach the small shelves at even intervals using vinyl glue and clamps. Let the structure dry completely. For a sturdy foundation, consider mounting it over a storage bench in the hallway.
3. Build the Front Frame
Join the multiplex frame elements at 45° angles. This staggered joint, offset from the shelf joints, adds strength and allows for thinner wood. Glue the frame onto the shelf assembly.
4. Install and Finish
Secure the bookshelf to the wall above the door using expansion plugs. Apply a coat of clear varnish to protect the wood and match your decor. For a complete look, add wall decor around the new feature.
Design Tips for Your Bridge Bookshelf
- Maximize Space: Use the top shelf for decorative items or baskets to keep clutter at bay.
- Lighting: Install lighting above or below the shelf to highlight your books and create ambiance.
- Style Integration: Coordinate the wood finish with existing furniture like bookcases and shelving units for a unified look.
Frequently Asked Questions
Can I build this without a table saw?
While a table saw ensures precision, you can use a circular saw with a guide. Just measure twice and cut slowly to avoid errors.
What if my door frame is wider than standard?
Adjust the dimensions accordingly. The key is to maintain the 242 mm height for the side elements and scale the width proportionally.
How do I secure heavy books?
Use strong wall anchors (expansion plugs) and ensure the glue joints are fully cured. For extra support, add a rug underneath to anchor the area visually.
Can I paint the bookshelf?
Absolutely! Sand the multiplex lightly, apply a primer, then paint with a durable finish. This works well with curtains or wall colors.
Is this suitable for a rental?
Yes, as long as you patch the holes when moving out. Use removable adhesive strips for lighter items if you prefer not to drill.
