The science of solid timber: mass timber and MHM houses, A-frame kits and glulam, explained by the people who build them.

Timber moisture content is only useful with its stage named
Supplier readings, finished-panel readings, product specifications and site measurements are four different numbers. Which one to ask for, and when.

A Wet Timber Frame Needs Time; a Rained-On Panel Needs Dry Days
A shower on an open shell means one thing for a solid panel and another for a frame. Where rain gets in, how each one dries, and what to check before the walls are closed.

Timber Frame Foundations: The Kit Mistake That Is Poured Before Delivery
Assembly errors show up against the instructions and get fixed on the day. A foundation out of line or level stops the crane. What to check before the kit arrives.

A Negative Wall Carbon Footprint Needs Its Fossil Part Shown
A wall can store more carbon than its making emits, on paper. How to read that production-stage figure, and the split to ask every manufacturer for.

Class E insulation does not decide a wall's fire rating
Wood-fibre is Class E insulation: it burns and it chars. A wall still earns its fire resistance as a tested assembly. Here is the evidence to ask for.

Cracks in Solid Timber Are Usually Drying, Not Failure
Cracks in massive wood worry owners more than anything else on a new build. What normal drying checks look like, and which cracks deserve an engineer's eye.

Most of a Timber House Timeline Is Decided Off Site
From signature to a weathertight shell: which stages of the build calendar are fixed, which are yours to move, and where dates actually slip.

A Dowelled Timber Wall Is Only as Good as Its Tested Connection
Cross-layered boards, grooved aluminium dowels and no glue line. What the connection's assessment proves, and where glued CLT is the better answer.

A Long Phase Shift Only Pays If the House Can Cool at Night
Two walls with the same U-value can meet a heat wave hours apart. That delay is worth paying for only when the house can shed its heat at night.

In a Timber Wall Build-Up, Layer Order Decides Performance
Interior finish, timber core, airtight line, wood-fibre insulation, ventilated gap and cladding: what each layer does, and why their order matters more than any single material.
