Daizen did it again! Cladding Glulam with WRC – grain matched with end grain!

  |   Design, Details, Joinery, Materials, Techniques

So we did it again! Another job where the team of highly skilled hand crafters have shown their expertise. What do you do when you’ll need large size clear WRC but can’t source enough material? The answer is simple: Get some treated glulam and add WRC as a veneer around it. It even works well with the end grain!

Curve from two timber laminated

  |   Design, Details, Materials, Techniques

Curve shape cut out from solid timber always challenge since it require large section of timber. It is not only hard to locate the fiber, timber will have significant check on surface since it contains so much difference in fiber tension depends on part of section in timber.

This can be solved by having two smaller timber laminated, much easier to find good fiber and also grain match. Seems like this approach can be develop further more by specifying timber grain in detail and how we re-saw to match grain!

It’s not what you do, it’s how you do it what makes the difference!

Kiln-drying boxed heart timber in large sizes to 15% moisture content in the core? It’s possible when you use the right technique.

Large timber sizes usually only come in boxed heart. Here at Daizen we use a “stress-relief-cut” on a non-exposed side of the timber to release the tension, that can get created during the drying process, trough this cut. This clean cut that goes all the way to the heart of the beam will eventually open up during drying and prevents the exposed beam sides from large checking.

An important benefit of the technique is that the change in the timber dimension happens already during the drying process. After the finish planing the timber size stays unchanged.

The picture below shows a 16” x 16” boxed heart post. The originally 1/4 inch cut opened up to nearly 1”, released all the tension here. The other sides ended up with no or only minor checking. The cut is getting covered by a joining stick-frame wall member.

The second picture shows a 9” x 20” beam with an 10” relief cut into the heart before it goes into the kiln. The cut will be later on top of the plate, non visible.

Stair by Daizen

  |   Design, Details, Joinery, Techniques, Uncategorized

Stairs are simply steps that allow us to move to different heights, but they also become a main design feature of the home. Stair design sometimes takes as much time as designing the house structure. Building stairs is not difficult, but to build with safety, furniture grade, it is not like a house structure – it requires a higher skill set and much drier materials. There are different types of stair design – cut out stairs, housed stairs, suspended stairs, spiral stairs, mono stringer stairs etc. Daizen has built over 100 stairs. Here are some examples of how Daizen approaches building one-of-a-kind stairs.

We have extended our services to build stair-focused projects and welcome your inquiries.

Suspended stair


This is a one-of-a-kind stair that is completely custom designed. The centre post is a solid 30″x30″ post, but there is no stair stringer to support the treads. Stair treads (steps) are supported at the centre post where they interconnect? Otherwise, the stair hangs from a railing made out of steel. Our process involved fitting all treads and the landing on a temporary support, then we built the steel railing and hung the treads to complete the project.



To keep the landing at the same thickness as the stair tread, we built a steel frame in a fish bone pattern and laminated the solid wood pieces from the top and bottom.

Housed stair



Housed stairs are very clean and strong. This type of stair can be assembled prior to installation, which allows for a faster installation process and makes the stair connection to the wall and floor easier to work with. The view from under the landing is also highly visible and we always pay attention to how the stair looks from all sides.


The landing is suspended from specially shaped member from above.

Steel stringer housed type stair: Wood is easy to shave and adjust but steel isn’t, so all measurement need to be accurate. This is a nice stair design that fits well within a modern style house.

Cut out stair

Brad Plowe-032

A typical cut out stair looks like this. The length of the spindles can be attached directly to treads. The stringer size must be a focus with this style because there is a big chunk of wood to be cut out.

Cut out stair during construction: Note that the landing is suspended. A lot of thinking and experimentation went into building this stair.

Spiral stair


Inside spiral stair is not always useable, but fits well when using a round log as a centre post.


Suspended spline shape stair: A uniform radius spiral stair is difficult to build, but when the radius is not uniform, it requires an actual scale template be built first. Railings were “three-dimensionaly” bent. The core was replaced with structural plywood with a through-bolt attached that is holding the end of the treads.



Stair on a regular type of frame: Once the walls are up, we build the stringer to the wall on site and make a template for all tread/steps. We pre-manufacture these in our shop so they may be installed, simply, on site.

Mono stringer stair


Mono stringer stairs with steel seem to be a favorite style of many people. Key to building this stair is consideration for adjustment because the steel receiver will not be in a perfect position.


Stuck up stair


This stair system is designed and engineered to have a 1,000 lbs point load in the middle of the stair. The core of each step is made out of glulam (GLB) and cladded with walnut. We allocated a gap between the GLB and walnut to allow for some movement and filled it with an expanded form. The walnut did not come any wider than 10″ so we grain-matched the board to look like solid wood. This project is ongoing and a completed photo will be posted later.

Stair 3

Onsite built stair. This project required more work on the curved railing. The grip profile is carved from solid wood.

It seems like most of our stair design specifications fit a 10″ run and 7.5″ rise and we make fine adjustments in this range. To make an open staircase, the maximum opening around the stair and railing by building code is 4”. This leads us to use 3.5″ thick stair treads, with the spindle space in the railing at 5″ apart. Our stair stock materials are in 4×12 select grade, dried to 12% minimum.

Jack rafter housing Kazu special

  |   Design, Details, Joinery, Techniques

Our lead builder Kazu came up with this jack rafter housing that ensure the tight fit that contains step housing to hip/valley rafter. With this details, as hip/valley shrink, fit gets tighter, and we make the housing width a hair smaller but it will bite into the corner to fit it tight. Extra depth on house ensure the bottom of stepped rafter to fit tight, wedge to control space is important, then washer head timber screw will close the gap on bottom to make the best fit!

Screw laminated beam

  |   Design, Details, Joinery, Techniques, Uncategorized

When the beam require extra strength running long span, stacking the two beam together would not simply increase the strength. In this project, we are putting keys in between the timber so it looks like the key is taking the shear on two beams but it is just decorative, real structural function is in fully threaded screw that is in a timber not visual.

Timber Cladding like a pro!

  |   Design, Details, Joinery, Techniques

Timber Cladding (Structural)

Sometimes there is no room for braces in your timber frame, especially when you want a clear opening without interruptions. One solution can be an engineered, heavy-duty steel frame, which is clad with grain matched timber. Professionally executed by our skilled craftsmen, you won’t be able to see the difference compared to solid wood. At Daizen, we pay particular attention to the fibre orientation to ensure a consistent appearance in wood characteristics and texture.
