For a subfloor, "clearance" generally refers to expansion gaps between sheets to prevent buckling, or ground clearance if you have a crawlspace.
1/2" plywood is too thin for most subfloor applications and will flex or sag, especially if joist spacing is 16 inches or more. This can lead to squeaky floors and structural issues. -> The minimum recommended is 5/8" plywood, but 3/4" is preferred for strength and long-term durability.
For non-termite-treated subfloor materials: Maintain a minimum clearance of 400 mm between the ground and the underside of the bearer.
The "Rule of 3" in flooring is a design principle that recommends using no more than three distinct flooring materials or color variations throughout your entire home. Limiting your design to three elements creates visual cohesion, prevents a chopped-up layout, and ensures smooth, intentional transitions from room to room.
Yes, you should leave a gap between plywood subfloor panels—typically 1/8 inch—to allow for expansion and contraction due to moisture changes. This prevents the plywood from buckling, which can cause high spots and squeaky floors. It is also recommended to leave a larger 1/4-inch gap at the perimeter walls.
For plywood subfloors, screws are heavily recommended over traditional nails. While framing nails rely on friction and can work loose over time (causing the floor to creak and squeak), subfloor screws have spiral threads that provide permanent grip and tightly pull the plywood down to the joists.
That tape will not hinder the subfloor joints to get wet since diffusion will lead water to the joints from the rest of the timber, but it might hinder the subfloor's capability to dry out if there's a leak, further increasing the damage. This is a good point since the subfloor isn't going to be water proof.
Wooden flooring – a fresh take on natural beauty
The year 2026 marks a time when wood regains its true power. Naturalness becomes the central theme in interior design, and wood tones – particularly warm, honey-coloured shades – will reign supreme in modern spaces.
The Top 10 Flooring Mistakes to Avoid
The 3-5-7 rule is a design principle that dictates grouping decorative objects, furniture, or art in odd numbers (specifically 3, 5, or 7). It breaks rigid, perfectly symmetrical pairings to create natural, eye-catching visual movement.
Simple air vents (commonly brick type vents with small holes in them) strategically positioned around the sub floor perimeter is the most common measure to ensure sub floor ventilation. This uses natural (or passive) cross flow of air, as shown in the below image.
Yes, the subfloor goes under the walls. Standard home framing involves installing the subfloor across the entire floor joists first, and then building and erecting the walls on top of it.

For most residential projects, 3/4-inch plywood is the industry standard and preferred choice, while 5/8-inch serves as an acceptable budget or lightweight alternative. The right choice depends primarily on your floor joist spacing and the type of finish flooring you plan to install.
Particle Board (Chipboard)
Particleboard is widely used to make furniture, as well as the construction industry as a cheaper alternative to plywood. It's commonly used for shelves, cabinets, and tabletops, as well as subfloors and wall panels.
Plywood is generally considered the better overall subfloor material due to its superior moisture resistance and ability to bounce back after drying. OSB (Oriented Strand Board) is cheaper and equally strong when dry, but it can suffer irreversible edge swelling if exposed to water.

Healthiest Flooring Types Compared
What are the main disadvantages of wood flooring? Wood floors are prone to water damage, can be costly to install, and may require regular maintenance such as refinishing. They are also susceptible to scratches and dents, especially in high-traffic areas.
The most timeless flooring colors are pale natural oak and medium neutral brown (such as walnut or standard oak). These natural wood tones bridge the gap between classic and contemporary and do not tie your space to a passing trend.
The 2026 wood color trends center on rich, natural warmth and deliberate contrast. As stark, ashy, and gray tones fade out, design focuses on honey-colored oak, espresso, and deep walnut to create layered, highly textured spaces rather than perfectly matched finishes.
Gray-toned hardwood and laminate. Wide plank farmhouse-style wood. Painted floorboards. Artificial or fake-looking wood.
Nails are a favorite for large jobs in construction because they're cheaper than screws and offer shear strength — or the ability to withstand shear pressure, where two surfaces slide past each other.
The best months to buy flooring are late December through February and mid-May to early June. During winter, flooring stores clear out old inventory with deep discounts—often 15–30% off.
In 2026, flooring trends revolve around warmth and natural textures, with cool, flat grays officially on their way out. The most popular colors include:
