Cooperation principles
We first clarify specialisation, regions and examples that may be verified. A listing is not a quality guarantee; a recommendation requires separate approval. Commercial placement does not replace technical assessment.

Builders
ZeroHouse Network: builders.
Examine how the building team is organised
A general builder needs more than photographs of completed houses: the team must work from an agreed document set. Clarify crew roles, specialist involvement and coordination responsibility. Foundations, façades and service penetrations can involve several people, so the client needs to know who resolves decisions at those interfaces rather than assuming every task belongs to the main contractor.
Inspect before finishes conceal the work
Ask how concealed operations, substitutions and deviations are recorded. The programme should leave access to insulation, seals and penetrations. Dated photographs tied to locations are more useful than attractive views with no construction-stage context. When the design changes, crews need the approved revision instead of interpreting a broad energy-efficiency concept on their own.
Compare the boundaries of estimates
One total may include procurement, transport and cleaning while another covers labour alone. Compare work items, units, exclusions and acceptance arrangements. Clarify how unexpected conditions and additional work are agreed. A directory status in this Network category is not a construction guarantee. Adding a participant requires verifiable information about its role; selecting one for your property still requires a specific brief. This distinction keeps general company information separate from commitments made for an individual construction project.
Work-area handover
Clarify how crews preserve inspection access and safe movement. Concurrent packages should not damage completed layers. Protection and work-area handover are organisational responsibilities rather than material properties.
