1. Project and Technical Calculations:
   • Квартиры в комплексе Marina Tiger имеют специфическую планировку: по документам они однокомнатные, но обладают отдельной кухней, расположенной между гостиной и спальней.
   • Concept: Expanding the small kitchen (5.5 sq. m.) for visual enlargement of the space while maintaining the isolation of the living room and bedroom (for family rental purposes).
2. Демонтажные работы: 
   • Partial Demolition of the Concrete Partition: between the kitchen and the living room to widen the opening and create an open visual space.
   • Dismantling of the old, uneven concrete ceilings.
   • Chasing all walls for the complete relocation of electrical wiring and outlets.
3. Installation of Engineering Systems:
   • Electrical System: Complete relocation of the electrical wiring embedded in the demolished wall. Moving all outlets (including the TV outlet) to convenient locations, and full replacement of the electrical routing for lighting.
   • Water Supply / Sewerage: Complete relocation of all utilities in the kitchen (for the dishwasher and oven) in accordance with the new layout.
   • Gas System (Key Nuance):
     • Relocation of the gas pipe in accordance with the new stove position.
     • Compliance with Strict Requirements: The relocation was carried out in the presence of the official gas contractor for this building, followed by leak inspection/testing.
   • Balcony Drain (in one of the apartments): Opening up the concrete on the balcony and coordinating access with neighbors to carry out repairs and ensure proper drainage of wastewater.
4. Substructure Installation:
   • Wall Leveling: The walls in the bedroom and living room, which were in very poor condition (holes, unevenness), were leveled 3–4 times until they reached a perfect state/condition.
5. Ceiling and Painting Works:
   • Installation of new gypsum ceilings throughout the entire area.
6. Finishing and Furnishing:
   • Hardware Complications: Sourcing and ordering non-standard locks for old balcony doors from China (with a 20-day delivery time), as the original locks had been discontinued. The locks were installed to ensure the functionality of the doors without a full replacement of the balcony units.
   • Final Assembly and Installation of the Kitchen.

"Final Stage: Diagnostics and Elimination of Unusual Noise"

1. Project and Technical Calculations:
   • Major Apartment Renovation
2. Installation of Engineering Systems:
   • Elimination of a Critical Defect at the Final Stage: During the stage of furniture delivery and assembly, a periodic, loud, "whining" soundwas discovered emanating from behind a wall and spreading throughout the entire apartment.
   • Complex Diagnostics: Involving the building engineer and several technical specialists. Initially, major issues with the main risers or pipes were suspected.
   • Cause Identification: The issue turned out to be a leaky faucet (valve) shutting off the hot water supplyThe presence of air in the system, combined with the wear and tear of the valve, led to resonance and the creation of a strong, persistent noise.

Remedy: The problem was solved by replacing the faulty valve..
