Preserving the View from Above

It’s been a while since I’ve showed you progress on my Charles Rennie Mackintosh (CRM) room box. I have been moving forward on it, but just didn’t have anything pretty to show. You see, I have been deliberating about how to enclose it. I want to keep the dust out but I also want to see inside and even reach inside to arrange the furnishings.

I finally figured out a way. I started by making a frame of MDF that would be fastened permanently to the walls. Then I worked out a way to add an atrium-style roof insert.

I picked up an 8″ x 10″ sheet of 1/8″ Lexan polycarbonate sheet at Lowe’s and tried a couple ways to cut it. I was pleased to find that my carbide-tipped blade on my Proxxon table saw worked perfectly. I was even able to tilt the blade to make beveled edges along the center to make the peak.

To create the end pieces I made a template from an old file folder to determine the dimensions for the triangles, and then had to figure out a way to cut them. A while back I bought a gadget from Micro-Mark that would enable me to safely slide my material through at an angle. I’m so glad I made that purchase; it worked perfectly!

To support the Lexan, I cut two more triangles of 1/8″ particle board that I had on hand. I planned to glue them to the inner side of my end pieces.

This photo shows the inner workings. You can see the routed edge around the opening and how I offset the two triangle end pieces. The bottom edge offset helps hold the triangles in place. The Lexan will sit on an 1/8″ “ledge” around the opening.

I need to get some glue that is formulated for polycarbonate to fasten the top seam.

The next time you see this project, I will have glued all the pieces together, painted it and removed the protective film. I’ll also move on to a much simpler method for closing the back. Thanks for staying with me on this project.


I’m a Californian living in Oregon. But home is where my miniatures are.

  1. This is a beautiful solution to a difficult problem. I wouldn’t have had the vision to create such a roof. I would have consulted with my husband. PS Thanks for fabric information. I’m still looking.

    1. Necessity is the mother of Invention. I needed robust, removable and transparent. I also wanted it to be in keeping with the inspiration architecture. Et viola! The roof designed itself!

  2. What a fabulous solution! I really like how your roof insert turned out. The additionally good thing is that it will let in light from above, so people can really see your beautiful work.

  3. This is brilliant, Sherrill! I love how you have found a way to utilize all of the features of your saw! Glad you found the perfect Lexan locally, too!

  4. That is a brilliant solution, Sherrill, and very neatly executed! I look forward to seeing the finished result. Oh, and I’m very envious of that gadget for cutting wood at an angle. I only have a very tiny table saw but I think I might be able to engineer a device like that to fit it. I’m going to try.

    1. Thanks so much. I’m excited to show you the result. I just have a couple more days of work before I have both the top and the end enclosed. It’s surprising how it completes the look of the structure. Good luck on making the angle jig for your saw.
