DIY Playhouse Trims and Balusters


This step by step diy project is about playhouse railings and trims plans. This is PART 3 of the playhouse project, where I show you how to build the railings for the porch and how to fit the decorative trims. The front porch railings will add an unique and appealing charm to the project and make it stand out. Take a look over the rest of my woodworking plans, if you want to get more building inspiration.

When buying the lumber, you should select the planks with great care, making sure they are straight and without any visible flaws (cracks, knots, twists, decay). Investing in cedar or other weather resistant lumber is a good idea, as it will pay off on the long run. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look. If you have all the materials and tools required for the project, you could get the job done in about a day.

How to build playhouse balusters and trims

Side wall - trims

Side wall – trims

The first step of the project is to fit the 1×3 trims to the sides of the playhouse and around the window opening. Align the edges flush and then insert 2″ nails to secure the trims into place tightly. Align the edges flush and leave no gaps between the trims.

Front wall - trims

Front wall – trims

Cut the trims and then secure them to the front of the playhouse. Use 1×3 lumber for all the trims, except for the top trim, which is made from 1×4 lumber.

Back wall - trims

Back wall – trims

Fit the decorative trims to the back of the playhouse. Align the edges with attention and then secure them into place with 2″ nails.

Side balusters

Side balusters

Fit the 1×3 balusters to the sides of the playhouse. Place the balusters equally spaced and then lock them into place with 2″ nails.

Front rails

Front rails

Fit the balusters to the front of the playhouse. Align the edges flush and then lock them into place tightly with nails.

Fitting the hand rails

Fitting the hand rails

Fit the handrail to the top of the posts, as shown in the diagram. Make 45 degree cuts so you can fit the slats over the joint. Use 2″ nails to secure the slats into place tightly.

Last but not least, you need to take care of the finishing touches. Fill the holes with wood putty and then smooth the surface with 120-220 grit sandpaper. Apply a few coats of paint or stain over the components, so you can enhance the look of the playhouse and to protect the components from decay.
