2026 Sarıyer Villa Renovation Guide: Value-Adding Transformations in Zekeriyaköy and Tarabya

# 2026 Sarıyer Villa Renovation Guide: Value-Adding Transformations in Zekeriyaköy and Tarabya

The Importance of Sarıyer Villa Renovation: Why a Specialized Approach is Required

Villas in the Sarıyer region require much more comprehensive planning than standard apartment renovations. The main reasons include spacious areas, unique architectural details, the need for harmony with the natural environment, and luxury living standards. While Zekeriyaköy villas typically require a specialized approach due to their large gardens and nature-integrated locations, Tarabya villas stand out with design solutions that maximize Bosphorus views.

Key Factors to Consider in Villa Renovation

Materials Used in Exterior Facade Insulation

In our Sarıyer villa renovation projects, we use XPS (Extruded Polystyrene) foam or stone wool (mineral wool). XPS foam is preferred especially in humid climates because it maintains insulation performance thanks to its waterproof structure. XPS insulation with 8-10 cm thickness per square meter costs 1,200 - 1,800 TL per square meter at 2026 prices.

Stone wool is a more environmentally friendly option and demonstrates superior performance in terms of fire safety. In villas near the Bosphorus in the Tarabya region, we apply special layered insulation systems to prevent damage that sea salt could cause to the structure.

The Critical Role of Roof Insulation

In villa roof insulation, we place stone wool or glass wool on waterproofing membrane for sloped roofs. For flat roofs, we use XPS foam with a waterproof coating on top. In high-altitude areas like Zekeriyaköy, snow load during winter months must be taken into account.

Luxury Material Selection: Recommendations for Sarıyer Villas

Material selection in Sarıyer villa renovation projects is critically important in terms of both aesthetics and durability. We serve in three main segments:

1. Premium Segment: Imported Ceramics and Granite

In villas in Tarabya and Zekeriyaköy, Italian and Spanish brand ceramics are generally preferred. Porcelain ceramics, with over 99% waterproofing rate, offer ideal solutions especially in bathroom and kitchen areas.

Granite countertops are preferred in kitchen islands and bathroom sink units. Granite is more durable than marble and easier to maintain. We use granite slabs with a thickness of at least 3 cm, especially in kitchen islands. At 2026 prices, premium segment kitchen costs range from 15,000 - 25,000 TL per square meter.

2. Ultra Luxury Segment: Marble and Custom Design

Marble finishes stand out for villas in the most prestigious areas of Sarıyer. Italian marbles like Calacatta and Statuario are used in kitchen islands and bathroom walls. Due to its natural structure, marble displays different patterns on each slab, giving each villa a unique character.

Custom-designed kitchen systems, island kitchens from German and Italian brands are frequently preferred in Zekeriyaköy villas. In 6-8 meter kitchen islands, special equipment such as built-in refrigerators, wine cellars, and coffee machines are integrated.

Spacious Kitchen Islands: Functional and Aesthetic Design

Kitchen Island Design Principles

When planning the kitchen island, we optimize distances between the refrigerator, stove, and sink. The total distance between these three points should be between 6-8 meters. In villas in the Tarabya region, the stove is placed on one side of the island, and the sink and preparation counter on the other side.

In the lower part of the kitchen island, we design corner rotating cabinets (lazy susan), deep drawer systems, and special item compartments. In the upper part, wall cabinets or open shelf systems can be preferred. In Zekeriyaköy villas, a wine cellar or a second sink can be integrated into the center of the island.

For kitchen island countertops, we use granite or quartz. Quartz, as an option between marble and granite, is more durable and easier to maintain. For cabinet doors, MDF with melamine coating or solid wood is preferred. In the ultra-luxury segment, Italian cabinet systems are used.

Luxury Details in Bathroom Renovation

In Sarıyer villas, bathroom renovation is designed not only as a functional area but also to create a spa experience. Bathroom areas typically 10 m² and above require custom design solutions.

Insulation Materials Used in Bathroom Insulation

In bathroom insulation, waterproofing is critically important. We apply the following layered system:

1. Waterproofing Membrane: Polyester felt-reinforced bitumen-based membrane is extended 20 cm upward at wall and floor joints.

2. Insulation Layer: XPS foam is placed under walls and floors.

3. Waterproof Screed: Special additive screed provides waterproofing.

4. Ceramic Underlayment Insulation: Waterproofing additive mixed into ceramic adhesive provides additional protection.

Fixture Selection: German and Italian Brands

In Sarıyer villa bathrooms, German brands like Grohe, Hansgrohe, or Italian brands like Gessi, Fantini are preferred. These fixtures stand out with surface coatings that are unaffected by lime and long lifespans. In shower systems, rain shower heads and body jets are integrated.

Garden and Landscaping Arrangement: Design Harmonious with Interior

In Zekeriyaköy villas, spacious gardens are designed as a natural extension of the interior. In villa renovation, large glass surfaces are used to maximize the transition between interior and garden.

Considerations in Garden Landscaping

In spacious gardens, drip irrigation and sprinkler systems are controlled with automatic timers. Considering Sarıyer's humid climate, irrigation programming should be specific to the region.

In garden lighting, LED spot lights and LED strip lighting are used. Tree trunk lighting and pathway lights enrich the nightscape.

Terraces opening from the villa's interior to the garden can be closed with enclosed glass systems (bi-fold or sliding doors). These systems, when fully opened in summer months, eliminate the separation between interior and exterior spaces.
