HOUSE CONSTRUCTION LEDGER / 2026 →
A house as
a system.
A versioned path from acquisition to operation: design, permits, execution, quality evidence, building services, Smart Home, commissioning and the first year of use.

What actually drives the build.
The public surface promotes only what is ready, active or blocking. Full operational state remains in private Control.

Knowledge at the decision point.
Every deep dive is tied to timing, acceptance and evidence. The field manual is not a detached encyclopedia.
QA / structure
Pre-pour gate
One of the most expensive defect classes is discovering an error only after the structural element has been cast.
WHEN / Before every structural concrete pour
QA / recordsHidden-works evidence
Every element that becomes inaccessible after the next trade should leave a traceable proof of execution.
WHEN / Before closing insulation, services, reinforcement and floor layers
EnvelopeExternal joinery acceptance
Window performance depends on support, fixing, seals and the insulation interface, not only the profile specification.
WHEN / Immediately after installation and before covering layers
DesignMEP coordination before construction
Service clashes with structure belong in the model and drawings, not under a hammer on site.
WHEN / Before technical design freeze and again before slabs
ManagementChange control
Every post-freeze change receives a cost delta, schedule delta and affected-system list.
WHEN / From design freeze through final acceptance
ProcurementQuote normalisation
Compare scope to scope, never price to price.
WHEN / Every material package or trade contract
