Ataşehir Renovation & Interior Guide: What You Need to Know

Building Types & Structural Features

Three building types dominate Ataşehir: (1) steel‑frame high‑rises built between 2000‑2010, (2) reinforced‑concrete blocks from 1990‑2000, and (3) prefabricated concrete panels in new residential projects. Steel frames have low load‑bearing walls, limiting structural alterations; concrete blocks carry more load but older units often suffer from moisture and insulation issues.

• •Steel frame: wall load capacity ~30‑40%, carrier wall changes difficult.
• •Reinforced concrete block: high load capacity, moisture control critical.
• •Prefabricated panel: fast installation, but requires extra sound insulation.

Permits & Licensing Process

Istanbul Metropolitan Municipality (IMM) and Ataşehir District Municipality require different approval levels. Interior alterations exceeding 30 m² need a “Operating Permit” and a “Structural Change Permit.” Required documents: design drawings, static report (mandatory for steel frames), energy performance certificate, and consent from the building’s management.

• •Under 30 m²: single‑level “Operating Permit”.
• •Over 30 m²: static report + approvals from both municipalities.
• •Permit timeline: 15‑20 business days from application.

Cost Distribution & Budget Planning

Obtaining a written fixed price after a free site survey is essential for budget control. In a typical 120 m² apartment, cost items distribute roughly as: 35‑40% walls & plaster, 20‑25% flooring, 15‑20% kitchen & bathroom cabinets, 10‑12% electrical‑mechanical, 5‑8% decorative details.

• •Walls & plaster: 35‑40% – waterproofing and acoustic insulation add cost.
• •Flooring: 20‑25% – varies with tile, parquet or LVT choice.
• •Cabinets: 15‑20% – includes custom fabrication and installation.

Climate & Material Selection

Ataşehir experiences a humid Marmara climate with wet winters and hot summers. Hence, moisture‑resistant drywall, waterproof plaster, and high‑R‑value insulation are recommended. Exterior shading devices (blinds, external curtains) reduce solar gain in summer, improving comfort and lowering energy use.

• •Drywall: choose class 120 water‑resistant type.
• •Thermal insulation: minimum EPS 100 mm or XPS 80 mm.
• •Solar control: exterior blinds can save 30‑40% energy.

Workmanship Warranty & After‑care

Güven Kardeşler provides a written workmanship warranty for all interior works; the period varies by project but is typically 12 months. Under warranty, non‑structural defects such as wall cracks, water leaks, and flooring shifts are corrected at no charge. Maintenance recommendations, an annual inspection checklist, and cleaning instructions are included in the contract.

• •Warranty period: usually 12 months for most projects.
• •Scope: walls, plaster, flooring, cabinet installation.
• •Annual care: moisture measurement, seal checks, repainting.

Frequently Asked Questions

How many days does it take to obtain a renovation permit in Ataşehir?

If the application is complete, the process usually finishes in 15‑20 business days; for urgent cases, the municipality’s “Fast Track” service can deliver permits in 7‑10 days.

What should I do if the load‑bearing capacity of walls is low in a steel‑frame building?

Use lightweight gypsum board partition systems instead of load‑bearing walls, and add steel profiles as reinforcement if a structural engineer recommends.

What percentage of the budget do kitchen and bathroom cabinets typically represent?

In an average project, cabinets account for about 15‑20% of the budget; opting for custom‑made units pushes the cost toward the higher end of that range.

Which insulation material is more suitable given the local climate?

For humid winters and hot summers, XPS and high‑density EPS are preferred; both meet moisture resistance and R‑value requirements, but XPS offers greater durability on exterior applications.
