You may have seen Tim around here before and on his own blog. I’ve invited him to contribute regularly to The Inspired Room because his practical remodeling ideas are smart, approachable, and inspiring. Having another perspective will add fresh ideas for the times when I need a new point of view, and I think readers will enjoy his hands-on tips.
Tim won’t be replacing anything — I’m still here — but I’m excited to share his remodeling know-how and simple projects that deliver big visual impact without excessive cost or complexity. So, welcome, Tim!

Looking for a simple idea to give a room character and style without spending a fortune?
Try turning the exterior inside. Using materials and details normally reserved for the outside of a house is an easy way to add texture, charm, and personality to an interior space. With a little planning and basic tools, you can create a striking accent wall or architectural detail in a single day.
Use Exterior Wall Finishes Inside
Think about restaurants and shops that borrow exterior textures and bring them indoors. You don’t need to recreate a street scene; small, well-chosen elements make a big difference. One of the quickest transformations is applying lap siding to an interior wall. Installed properly it can be a one-day project: cut, nail, paint or finish, and you have a fresh, character-filled surface.
Interior siding can be finished in many ways — paint it crisp white for a coastal cottage feel, stain it for warmth, or distress it slightly for a weathered look. The secret is to choose materials and a finish that complement the rest of the room so the siding feels intentional, not out of place.
Trim Windows and Doors With Exterior Materials
Exterior-style trim and shutters bring instant authenticity. If you already have a window, framing it with substantial exterior trim pieces and adding shutters creates a strong focal point. If you don’t have a window, you can build a faux window: add casing, sill, shutters, and hardware to give the appearance of an exterior opening. Even nonfunctional elements, like decorative hinges or painted “panes,” add visual weight and interest.
Consider using 1×6 lumber for baseboards and corner boards to emulate exterior proportions. Adding real or faux hardware — hinges, latches, or decorative straps — makes the installation read more like an exterior detail. Slightly beating up the wood or giving it a light wash of paint can enhance that authentic, weathered charm without compromising the overall quality of the room.
Think About What’s Behind the Boards
Some siding styles intentionally leave small gaps between boards for a rustic feel. When you choose a treatment that exposes gaps, think about the wall color behind the boards. A darker background will add depth and help the seams look deliberate. In one project I renovated a child’s room using interior siding and left narrow gaps; painting the original wall a contrasting color made the siding read as a layered design element rather than an unfinished installation.
Pay attention to how other decorative elements will interact with the siding: wallpaper borders, moldings, or pictures can show through gaps if you’re not careful. Planning and a test section will save you an afternoon of rework and ensure the final result looks polished.
When done well, these interior-exterior mashups create a cozy, lived-in feeling. The look can range from crisp and coastal to rustic and reclaimed depending on materials and finish choices. For a bedroom, living room, or entryway, an interior wall with exterior siding or a faux window treatment becomes a dramatic backdrop that defines the space without requiring a full remodel.
In short: to create an accent wall or room with character, simplicity, and relatively low cost, consider bringing exterior materials and details indoors. Turning things inside out is an easy, effective way to add style.
