After the merge

What remains before design sign-off

The owner brief is aligned. These remaining items require interior-designer input, specialist confirmation, measurements or later selections; they do not reopen the completed brainstorm and merge.

Context and Design Intent

Coordinate electrical, network, plumbing, cooling, ventilation, accessibility, smart-home infrastructure and lifecycle service access before partitions, carpentry and finishes are fixed. The home should be reliable, maintainable, uncluttered and adaptable to additional occupants and future needs.

This is the authoritative merged Whole-home Systems record. It preserves the initial project baseline, the jointly agreed design direction and both owners' completed independent positions without treating a deferred position as agreement.

Non-Negotiables

SYS-SP-001 — Agreed and reclassified as non-negotiable on 23 August 2026: Fully rewire the home and size the new electrical installation for the confirmed and reasonably foreseeable loads, including the planned AC system and selected water-heating system. A professional inspection may inform implementation details but does not reopen the agreed full-rewiring scope.
SYS-NN-002 — Provide wired network connections to every room using cabling and network equipment rated for the selected PoE standard. Yasmin deferred network specifics to Fahmi; Fahmi's detailed network positions remain attributed below.
SYS-NN-003 — Provide permanent water-supply and wastewater connections for the robot-vacuum dock, water dispenser and dehumidifier, coordinated with the authoritative area masters. Yasmin deferred the detailed arrangement to Fahmi.
SYS-NN-004 — Provide ceiling or suitable fixed fans throughout the applicable rooms and two AC blowers for the combined Living/Dining zone. Exact room solutions remain governed by the area masters.
SYS-NN-009 — Agreed: Provide barrier-free or gently transitioned movement through the Entrance, Living/Dining area, bedrooms and Service balcony. Resolve the entrance floor drop and preserve robot-vacuum movement; robot access into WC1 and WC2 is not required.
SYS-NN-010 — Agreed: Keep maintainable plumbing joints, isolation valves, AC routes, drainage, electrical controls, network equipment and other lifecycle service points accessible for inspection, isolation, repair and future HIP-related work. Do not permanently conceal components that require access.

Strongly Preferred

SYS-SP-005 — Agreed: Keep electrical, networking, plumbing, AC and other service routes neat, accessible and coordinated before carpentry.
SYS-SP-007 — Agreed: Use warm contemporary minimalism as the whole-home design direction: clean geometry, uncluttered surfaces and restrained detailing.
SYS-SP-008 — Agreed: Use a coordinated palette of warm neutrals, natural walnut and controlled black accents across shared spaces. Review physical samples before approving fixed finishes.
SYS-SP-011 — Coordinate Yasmin's distributed-charging requirement with Fahmi's proposed shared charging station so accessible charging is available without oversized carpentry or cable clutter. Final distribution remains under SYS-DO-026.
SYS-SP-012 — Agreed: Provide an AC unit in the Service balcony subject to structural, electrical, condensate, ventilation, window and equipment-layout feasibility, consistent with the Service-balcony master.
SYS-SP-013 — Agreed: Use ceiling fans in the bedrooms, Living area, Study and Balcony, and a suitable fixed corner fan in the Kitchen. Apply the Dining and Service-balcony fan decisions from their area masters.

Decisions Outstanding

SYS-DO-006 — Compare gas instantaneous, electric instantaneous and electric storage water-heating systems against simultaneous bathroom use, kitchen hot water, delivery time, temperature and pressure stability, operating cost, space, utilities and service access.
SYS-DO-024 — Select the central network-cabinet location, incoming-fibre route, access-point locations, mobile-internet antenna route and UPS scope after verifying the equipment inventory and cable paths.
SYS-DO-025 — Finalise the complete circuit and load schedule, distribution-board size, dedicated high-load circuits, spare capacity and any space for DIY energy-monitoring CT clamps after the AC and water-heating systems are selected.
SYS-DO-026 — Finalise the distributed charging-point plan and the location, capacity and form of Fahmi's proposed shared charging station without oversized carpentry or surface clutter.
SYS-DO-027 — Finalise the whole-home lighting and switching plan by coordinating the requirements already agreed or attributed within each area master.
SYS-DO-028 — Confirm the owner-selection and equipment schedule, required information, dependencies and decision deadlines before affected design, services, carpentry or procurement are locked in.
Detailed requirements and coordination

Provisional Ideas

SYS-P-014 — Fahmi: Consider domestic smoke alarms after assessing type, quantity, location, power method, visual effect and nuisance-alarm risk.
SYS-P-015 — Fahmi: Investigate a lightweight, low-footprint Living-area partition that can reduce cooled-air escape when only one Living/Dining blower is operating without obstructing circulation.
SYS-P-016 — Fahmi: Consider groutless floor finishes where suitable; otherwise use an easy-maintenance grout system with performance comparable to the acrylic grout in the current home.

Subject to Feasibility

SYS-SF-017 — Coordinate Yasmin's flush, seamless switch and socket plates with Fahmi's requested deep wall boxes, neutral conductors and smart modules. Demonstrate safe box depth, heat dissipation, device fit, service access and finish tolerances before selection.
SYS-SF-018 — Have the AC specialist demonstrate the complete blower, compressor, refrigerant, condensate, ventilation and maintenance arrangement. Fahmi proposes AC in every room and two outdoor compressors capable of cooling the full home; preserve independent zone use and protect vulnerable electronics from likely leak paths.
SYS-SF-019 — Confirm the Service-balcony AC against the retained washer, future dryer, robot dock, drying rack, fan, dehumidifier, windows, grilles and circulation.
SYS-SF-020 — Professionally inspect all walls for mould, moisture damage, loose plaster and substrate defects before replastering. Treat mould and resolve its moisture source before the agreed full replastering proceeds.
SYS-SF-021 — Coordinate new windows, grilles, restrictors and maintainable insect screens with the Common-corridor and other area masters, including airflow, privacy, security, cleaning and applicable constraints.
SYS-SF-022 — Confirm future cable-route or spare-conduit methods, locations and realistic capacity before finishes close; do not promise inaccessible or impractical routes.
SYS-SF-023 — Test all selected lamps, drivers, dimmers, physical controls and smart modules for compatibility, serviceability, flicker and acceptable minimum brightness.

Resolved Joint Positions

SYS-DIFF-001 — Full rewiring commitment: Resolved jointly on 23 August 2026. Fully rewire the home as recorded under SYS-SP-001, now classified under Non-Negotiables while retaining its stable requirement ID.
SYS-DIFF-002 — Service-route presentation: Resolved jointly on 23 August 2026. The owners clarified that their concerns apply to different services rather than representing competing whole-home rules. Conceal large sewage and similar plumbing pipes where appropriate while retaining all required inspection and HIP access. Keep AC condensate piping visible and serviceable where practical; if it must be boxed for appearance, use removable access rather than permanent concealment.
SYS-DIFF-003 — Replastering scope: Resolved jointly on 23 August 2026. Fully replaster the home after the professional wall assessment, proper mould treatment and correction of the underlying moisture source.

Attributed Owner Positions

These positions remain attributed and are not jointly agreed unless explicitly reclassified later. Yasmin expressly deferred networking, smart-home, water-heating, gas-provision and permanent-connection specifics to Fahmi; that deferral is not agreement.

Fahmi

SYS-FP-029 — Network and resilience: Use stable UniFi-class Wi-Fi with wired backhaul to every access point, wired connections to every room including Kitchen and Service balcony, a ventilated and discreet central cabinet, an accessible incoming-fibre route, secondary mobile-internet failover with a tidy antenna position, spare power and a technically sized UPS for the network stack. Compare approximately 30-minute, one-hour and four-hour UPS scenarios.
SYS-FP-030 — Electrical and smart-home infrastructure: Provide a neutral conductor and deep wall box at every switch, wiring and routes for the video doorbell and selected endpoints, power for planned motorised curtains or blinds and CCTV, suitable sensor positions, clearly labelled protective devices, dedicated high-load circuits, distribution-board spare capacity and accessible future cable routes. Reserve safe board space for one DIY Shelly CT clamp per MCB.
SYS-FP-031 — DIY smart-home boundary: Fahmi expects to select and install most smart devices himself. The renovation should provide maintainable infrastructure and preserve suitable locations for leak, presence or motion sensors rather than requiring the ID to supply a complete smart-home system.
SYS-FP-032 — Charging: Provide a neat shared charging station for phones, tablets, watches, power banks, small toys and battery shavers, with replaceable chargers, spare capacity, heat dissipation, cable management and accessible servicing.
SYS-FP-033 — Lighting: Provide layered, separately controllable and appropriately dimmable lighting in every room, including task lighting, indirect lighting where suitable and low-brightness night modes where useful.
SYS-FP-034 — Cooling: Provide independently usable AC in every room, two Living/Dining blowers and two outdoor compressors sized to cool the whole home. Keep major trunking visible where practical, protect electronics from likely condensate leaks and preserve routine servicing access.
SYS-FP-035 — Water and drainage: Provide an accessible individual shut-off valve for every water-fed fixture or appliance; hot water to both showers, both basins and the Kitchen sink; capacity for simultaneous bathroom use; one central heater; future gas-supply provision even if electric heating is initially selected; and future water/drainage provision where reasonably foreseeable.
SYS-FP-036 — Maintenance and handover: Keep floor traps, filters, windows, curtains, AC units, valves and access panels practical to clean and service. Require a structured handover walkthrough, available as-built information, material and paint identifiers, labelled samples where useful and renovation warranties.
SYS-FP-037 — Materials: Use floors that tolerate regular washing, moisture-resistant carpentry in exposed zones and grout or groutless systems selected for low maintenance. Treat mould and its moisture source before finishing.
SYS-FP-038 — Windows: Replace the home's windows and grilles and provide maintainable insect or pest screening, subject to the specific Common-corridor and area requirements.
SYS-FP-039 — Selection coordination: Require the ID to create, own and maintain a coordinated owner-selection and equipment schedule with deadlines, dependencies and consequences for late information. Do not finalise owner-dependent services or carpentry using unverified assumptions.

Yasmin

SYS-YP-040 — Charging and spaciousness: Distribute accessible charging throughout the home rather than relying on one foyer point, and avoid infrastructure-related carpentry that makes rooms feel cramped.
SYS-YP-041 — Electrical finishes: Use flush-mounted switch and socket plates with a seamless appearance consistent with the agreed whole-home design direction.
SYS-YP-044 — Cooling and fans: Provide Service-balcony AC if feasible; use ceiling fans in the bedrooms, Living area, Study and Balcony and a corner fan in the Kitchen. Yasmin deferred Dining and Service-balcony fan specifics to Fahmi and the area masters.

Whole-Home Coordination

This file is the authoritative coordination source for shared electrical, network, plumbing, AC, accessibility and service-access requirements. Area masters control the more specific room arrangement and must cross-reference the applicable whole-home requirements rather than silently overriding them.

Preserve the jointly resolved Service-balcony robot-dock location, AC intent, dehumidifier drainage and fan/drying arrangements.
Preserve the resolved bathroom ceiling-fan, vanity-power and water-heating cross-references.
Coordinate the Common-corridor window merge with SYS-SF-021 and Fahmi's broader new-window position.
The deferred bicycle-storage topic is now eligible for joint review but remains outside this merge until both owners authorise that review.
