Walk into a well-designed timber frame home and the first thing you notice is space. The rooms open into one another, the ceiling lifts overhead, and daylight reaches every corner. That’s why so many people look for timber frame house plans with an open floor plan. Hamill Creek Timber Homes has designed custom timber frame homes for over 35 years from its shop in Meadow Creek, British Columbia, and ships frames across North America. That open feeling isn’t luck. It comes from how a timber frame carries weight, and from design choices that turn that strength into connected living space. Here is how open timber frame house plans work, and how to plan one for yourself.
How Timber Framing Frees a Home From Interior Walls
A timber frame carries the weight of the house through a skeleton of heavy posts and beams. These timbers are joined with mortise and tenon joinery, a traditional method where a shaped tongue on one timber, the tenon, fits a carved pocket in another, the mortise, locked with a wooden oak peg. Because the frame holds up the roof and floors, the inside walls don’t have to. That’s why open floor plans suit timber framing so well.
In a conventional stick-built home, many inside walls are hidden supports, so removing one often means adding a beam or post. A timber frame works the other way around. The support is built into the frame you can see, so timber frame house plans can leave the interior open by design. If you want the basics first, our guide to what a timber frame home is explains how the pieces fit together.
Each frame is engineered for its own design, so an open span’s width is set by the plan and confirmed by Hamill Creek engineering.
Great Rooms and Open Floor Plans That Flow
The great room is where an open floor plan comes to life. In many open concept timber frame homes, the kitchen, dining area, and living room share one large space under a continuous run of timbers. You cook, eat, and relax in view of everyone else, which makes open layouts feel social.
An open plan still needs a sense of separate areas, and good design creates them without walls. A timber bent, one full cross-section of the frame, can mark where the living room ends and the dining area begins. An island anchors the kitchen; a ceiling-height change, an area rug, or pendant lights set off another zone. Long sightlines and shared daylight make the room feel larger than its square footage.

Vaulted and Cathedral Ceilings for Open Space Overhead
Expansive open space is about height as much as floor area. When the roof structure becomes the ceiling, the exposed timbers rise overhead and the room fills with volume and light. This is where timber frame home designs stand out, because the trusses that hold up the roof are meant to be seen. The best timber frame house plans use that height as much as the floor space.
A vaulted ceiling follows the slope of the roof, often on one side, for a lifted, angled look. A cathedral ceiling rises evenly on both sides to meet at a central ridge, framed by matching timber trusses. Both open the room upward and show off the craftsmanship. Above an open great room, a high ceiling feels grand.
| Ceiling Type | Shape | Best For |
|---|---|---|
| Vaulted | Follows the roof slope, often on one side | Adding height and a modern, angled look |
| Cathedral | Rises evenly to a central ridge | A symmetrical great room with exposed trusses |
Both pair beautifully with exposed Douglas Fir timbers.
Open-Concept Layouts: Ranch, Loft, and Contemporary Designs
Open timber frame house plans work at any size and style. You can build a single-level home, a two-story great room with a loft, or a modern design wrapped in glass, and the frame keeps the interior open. Here are three popular directions for open concept timber frame homes.
Keeping an Open Home Warm, Quiet, and Efficient
A modern ranch style timber frame home keeps everything on one level around a central great room. With no stairs, it suits retirement homes and anyone planning to age in place, and it settles naturally onto mountain and lakefront lots. Open ranch timber frame home plans put the kitchen, dining, and living space at the heart of the home, with bedrooms around them. For a smaller footprint, our tips on maximizing space in a one-story timber frame home you’ll see how roomy an open layout can feel.
Lofts and Overlooks
A loft adds space without closing the plan. Built over part of the main floor, it opens onto the great room below through a railing, so both levels share light and views. It works as a home office, reading nook, or extra bedroom.
Contemporary Open-Concept Designs
Contemporary timber frame home designs pair an open layout with large windows and clean lines. Walls of glass pull in daylight and frame the view, so the open space seems to reach outdoors. These homes stay comfortable through Structural Insulated Panels, or SIPs, foam-filled wall and roof panels that give strong thermal performance in any climate.

How Hamill Creek Designs a Custom Open Floor Plan
Every one of our timber frame house plans starts with your vision and your building site. The in-house design team works in real-time 3D CAD, so you can adjust the layout before anything’s cut. You can begin with a fully custom sketch or start from one of our pre-designed timber frame floor plans and open it up to suit you.
Once the design is set, it moves through a Design Development Contract, engineering, and production. Hamill Creek runs its own sawmill and shop in Meadow Creek, British Columbia, where more than 20 skilled craftspeople cut and shape each frame from sustainably sourced Douglas Fir and Western Red Cedar. Before a frame ships, the crew test-fits the whole structure in the shop, so every joint is checked and the open layout goes together cleanly on raising day.
Hamill Creek Timber Homes is a specialist timber frame designer and manufacturer, that’s why the frame and the floor plan are designed as one. Cost depends on size, finishes, and location, so the next step is to browse our timber frame home plans and share your ideas.
Open Timber Frame Floor Plans: Common Questions
An open floor plan in a timber frame home is a layout where the main living areas, the kitchen, dining, and living room, share one space instead of being divided by walls. Timber framing makes this natural, because the posts and beams carry the weight of the house, so interior walls are not needed for support.
In most cases, no. The timber frame carries the roof and floor loads, so interior walls can be placed for privacy or storage rather than support. Each design is still engineered for its own site, so the open spans are set by the engineering for that home.
A vaulted ceiling follows the slope of the roof, often on one side, while a cathedral ceiling rises evenly on both sides to a central ridge. Both raise the ceiling above standard height and show off the exposed timber trusses. The difference is symmetry.
Yes. A timber frame floor plan can be fully custom, or it can start from a pre-designed plan that is then modified to fit your family and your site. Hamill Creek designs every home in-house with 3D CAD, so the layout can be adjusted before the frame is built.
Yes. Open floor plans remain one of the most requested features in custom homes, because they feel spacious and make it easy to gather. In a timber frame home, the open layout also puts the beauty of the frame on view.
