Büyükçekmece — Single-Move Bioclimatic Pergola and Guillotine Glass

Büyükçekmece Project: A Four-Season Terrace with Single-Move Bioclimatic and Guillotine Glass

Carried out by GlobalTente in Büyükçekmece, Istanbul, this application is a four-season-usable terrace transformation project combining a single-move bioclimatic pergola with guillotine glass systems. Completed turnkey in approximately 5 weeks, the project transformed the outdoor space into a comfortable living area all year round with its aesthetic look in harmony with modern architecture, durable aluminium construction and automatic system details. When the sun-rain-ventilation control provided by the bioclimatic pergola above combined with the opening façade offered by the guillotine glass on the sides, the terrace gained a sheltered, airy volume independent of weather.

Büyükçekmece is a district of Istanbul on the Marmara coast, wind-exposed due to the sea and with variable weather. The customer's terrace was an area that benefited from the sea and surrounding view in good weather but could not be used on windy and rainy days. The need was to transform the terrace into a flexible space that could both enjoy the open air and stay sheltered when closed. So the solution was designed in two layers: roof control with a single-move bioclimatic pergola above, and façade control with guillotine glass systems on the sides. This combination let the terrace be used in four seasons while preserving the view.

A single-move bioclimatic pergola is an economical, effective roof solution suited to the terrace geometry; the louvres tilt in one direction to drain water away from the view side and create a plain roof line. Guillotine glass was the ideal choice for the side enclosure: since the glass panels open by sliding vertically upward, they require no side stacking area and allow the glass to fully open on a façade with a view. In good weather the panels are lowered, and the sea air and view integrate with the terrace; in bad weather they are raised to close against wind and rain. The façade kept bright by the guillotine glass preserves the view and openness even when closed. The combination of these two systems made the terrace usable year-round in Büyükçekmece's windy coastal climate.

Technical Solution and System Details

The pergola's load-bearing columns were designed with internal gutters to conceal the drainage; so rainwater was directed to the ground without a visible pipe. The guillotine glass rails were brought together with the pergola's load-bearing structure on the same axis and in the same colour, making the two systems look like a single whole. The louvre and glass motors were chosen from silent, long-lasting tubular motors; the whole system was set up to be easily managed by remote.

Project Details and Process

The project started with measuring the terrace, evaluating the column points and planning the drainage route. Production was carried out in GlobalTente's own manufacturing infrastructure in sizes specific to the terrace. During installation, the bioclimatic pergola's load-bearing system was set up first, then the louvre mechanism was levelled; afterwards the guillotine glass rails and panels were placed. Water tightness was verified with a controlled water test after installation. The turnkey approach let the customer work with a single point of contact, completing the process in approximately 5 weeks.

The wind exposure of the coastal area affected both the system choice and the installation details. The rail and gasket details were carefully applied so the guillotine glass works solidly and watertight against wind. The bioclimatic pergola's drainage was calculated so there would be no pooling against the heavy rains by the sea. The priority of preserving the view required planning the louvre direction and glass placement so as not to block the view; this was a balance of both technical and aesthetic work. The choice of aluminium and powder coating provided long life against corrosion in this location close to a sea climate.

When the project was completed, the terrace became a sheltered living area usable in four seasons while preserving the view. In summer the louvres are opened for shade and natural ventilation, and the guillotine glass panels are lowered to let the sea air in; on windy and rainy days the louvres and glass are closed to turn the terrace into a sheltered volume. The modern aluminium line of the bioclimatic pergola and the transparent surfaces of the guillotine glass added both functional and aesthetic value to the terrace. The customer could now use the view terrace all year round.

The strongest aspect of this project is that the two systems complement each other. While the bioclimatic pergola controls the sun, rain and ventilation from above, the guillotine glass cuts wind and rain from the sides but keeps the view open. When the two work together, the terrace fully becomes an outdoor room: open and airy in summer, closed and sheltered in winter. This versatility, which a single system (only a pergola or only glass) cannot offer, raises the terrace's usage time from a few months of the year to almost all of it. The vertical operation of guillotine glass is especially valuable on view coastal terraces, because it requires no side stacking area and leaves the view uninterruptedly open. This combination is one of the most preferred solutions for view residential terraces.

Büyükçekmece's location on the Marmara coast means sea breeze, humidity and variable weather; this causes an open terrace to stay idle for much of the year due to wind and rain. The system combination chosen in this project responds precisely to this climate: while the bioclimatic pergola controls the summer sun and sudden rain, the guillotine glass cuts the sea wind and spray. The drainage solved with concealed gutter columns let the terrace dry quickly even in heavy rain. So a terrace with a view but exposed to wind turned into a comfortable living area year-round. This project is a concrete example of making an outdoor space livable in coastal climates while preserving the view.

Material choice is critical in locations close to a sea climate. The aluminium construction and electrostatic powder coating used in this project do not rust or fade against humid, salty coastal air; this is the right choice for longevity. Maintenance consists of cleaning the bioclimatic louvres and gutter channels once or twice a year, checking the motor and gaskets, and cleaning the guillotine glass rails. The glass surfaces preserve their transparency by being wiped regularly against marks left by sea salt. GlobalTente provided post-delivery maintenance guidance and service support, ensuring the system works with first-day performance for years.

For a view terrace, the most important design priority is not to block the view. In this project, the slim profile structure of the bioclimatic pergola and the frameless/slim-frame design of the guillotine glass were chosen to preserve the view from the terrace with minimal interruption. The colour of the pergola and glass profiles was chosen in harmony with the building's façade for an integrated look. When the louvres open, the sky remains visible; when the guillotine glass is lowered, the sea view remains uninterrupted. This aesthetic care made the terrace not just sheltered but also a sleek living area that enjoys the view.

The value of the project emerges in the terrace being usable in different ways throughout four seasons. In summer the louvres are partly opened for shade and natural ventilation; the guillotine glass panels are lowered to let the sea breeze in and the terrace becomes an open balcony. In spring and autumn, variable weather is when the system is at its strongest: the louvres open when the sun comes out and close in sudden rain; the guillotine glass cuts the wind to keep the terrace comfortable. In winter the louvres are closed and the guillotine glass is raised to turn the terrace into a fully enclosed volume; with a heater added it is usable even in cold weather. This scenario let the view terrace be used as a living area not just for a few months of the year but for almost all of it.

In the project, both the bioclimatic pergola and the guillotine glass were set up to be easily managed by remote. The louvre angle is steplessly adjusted by remote to control the amount of shade according to the time of day and the weather; the guillotine glass panels can be lowered and raised with one button. This automation let the terrace adapt instantly to the weather: in sudden rain the louvres and glass are closed within seconds to make the terrace sheltered. Infrastructure was left for optional wind and rain sensors, providing the possibility to switch to fully automatic operation in the future. This ease of use encouraged the terrace to be used effortlessly and frequently in daily life.

When choosing a side-enclosure system on a view terrace, the most important criterion is how much the system preserves the view. Systems such as sliding glass require a side stacking area, and the area where the panel stacks can create an obstacle on the façade; guillotine glass needs no such area since the panels slide vertically upward and lets the façade fully open. This is a decisive advantage especially on view and narrow façades. Moreover, guillotine glass preserves the view and brightness with its transparent surface even when the panels are lowered. This is the main reason guillotine glass was chosen in the Büyükçekmece project: on a sea-view terrace, both wind protection and an uninterrupted view were provided with the same system. This makes guillotine glass one of the most suitable options for the façade solution of view coastal terraces.

Running the project turnkey was central to the customer experience. Managing the survey, measurement, production, installation and test stages from one hand provided the flawless integration of the two different systems (pergola and guillotine glass) and single-point-of-contact assurance. The customer worked with a single team without carrying the burden of coordinating between different suppliers. The two systems meeting on the same axis and in the same colour was only possible with a process planned from one hand; this is the main reason for the integrated and aesthetic result. The turnkey model offered a decisive advantage in both time and quality in multi-system projects.
