Building Entrance Doors

What Is a Building Entrance Door?

A building entrance door serves the shared lobby of an apartment block or residential complex and is built at a larger size than individual unit doors. It represents the building's street-facing character and, since it opens far more often during the day, needs a wider leaf and a sturdier mechanism. Wood-grain finishing is the most common surface here, but what sets this category apart is its glass use — most models include a glazed panel in the leaf.

Glass brings natural light into the lobby and lets residents see who is outside before opening. The range leans mostly modern, with classic and more monumental-looking models available for larger, more formal entrance halls.

Finish, Glass and Color Options

Wood-grain tones span from light oak to deep reddish-brown, with simpler black and white lacquer models also in the range. Glazed models typically use tinted or frosted glass to preserve privacy, and a few use a diffusing white louvre panel that lets light through without full transparency. Common hardware on double-leaf models includes a vertical S-shaped chrome handle or a horizontal bar handle, usually paired with cylinder locks and a peephole.

Size and Installation

Building entrance doors use a standard frame opening of 145x215 cm, finishing at 165x223 cm once trimmed, with frame depth adjustable to 20 or 24 cm depending on the project. These dimensions match common lobby openings, though every building can carry its own architectural plan. An on-site measurement before installation matters especially for double-leaf and glazed models, where frame depth needs to match wall thickness correctly.

What Drives the Price

Price depends on leaf size, whether and what type of glass is used, the level of handle and lock hardware (such as double cylinder locks), and the choice between wood-grain or lacquer finish. Double-leaf models cost differently since both leaves need producing. Use the quote request on the product page or share your frame measurements for a price matched to your building's entrance.

Care

Glazed models need regular glass cleaning, while wood-grain or lacquer panels just need dusting with a soft cloth. Since this door is used far more often than a unit door, regular checks on hinges and the lock mechanism matter more here than in other categories.

Ordering and Where It Fits Best

Each model shows its price in your chosen currency (TRY, USD or EUR), with a quote request link where no price is set; once payment is made the order enters production, and pre-ordering can bring forward larger, double-leaf orders. Delivery covers Istanbul, the rest of Turkey, and international shipping, with cargo and installation usually planned as a separate step given the size of these doors. For management companies and contractors ordering across several building entrances at once, sending a single measurement list for all openings speeds up the process.

Hardware and Where It Fits

Glazed models suit lobbies that want natural light and the ability to see outside, with tinted or frosted glass preserving privacy; wood-grain finishes suit a warmer welcome, while black or white lacquer models suit a more minimal facade. Double-leaf models handle higher foot traffic better, making them a practical fit for larger complexes and office blocks. Common hardware includes a vertical S-shaped chrome handle or horizontal bar handle, usually paired with cylinder locks and a peephole; given how often this door is used, lock hardware suited to heavy daily use matters, and requests such as an automatic closer can be discussed with us.

Why Build to Measure?

Building entrances are rarely standard apartment size and often come with their own unique opening; frame depth, wall thickness and the need for a double leaf vary from building to building. Custom production ensures the door fits your lobby exactly, removing the risk of gaps or mismatches after installation.
