Kitchens, Bathrooms and Mechanical Cores

Use service zones intelligently

Back-to-back bathrooms, stacked plumbing and compact mechanical rooms can reduce piping runs and module connections. They can also concentrate risk if access is poor.

Confirm cleanouts, shutoffs, filters, panels and equipment can be reached after modules are joined and finishes are installed.

Plan wet-room details

Waterproofing, fixture clearances, exhaust and floor transitions should be resolved in factory drawings. Transport movement can affect brittle finishes, so ask how tile and stone are protected.

Kitchen islands and heavy counters may be installed on site depending on module limits and lifting strategy.

Coordinate equipment and climate

Heating, cooling, ventilation and water-heating choices depend on destination climate and energy rules. Ducts and refrigerant lines crossing modules need defined connection and testing procedures.

Allow for condensate, combustion safety where applicable, noise and replacement paths for future equipment.

Apply this guide to a real project

For kitchens, bathrooms and mechanical cores, create a dated project note tied to the destination address and current drawing revision. Identify the authority, designer, factory or contractor responsible for each unresolved item. Attach the written evidence for ‘Can every shutoff, filter and service panel be reached?’ and ‘Which finishes or appliances are installed after the set?’ rather than recording a verbal assurance.

Before a deposit, production release, shipment or final payment, convert every open question into a named action with an owner and deadline. Keep superseded drawings and decisions in the record so later inspectors, lenders, insurers and future owners can understand why the completed house differs from an early sales plan.

Questions to resolve before proceeding

• Can every shutoff, filter and service panel be reached?
• Which finishes or appliances are installed after the set?
• How are cross-module plumbing, ducts and wiring tested?
• Can major equipment be replaced without dismantling the house?
