Custom Patio Doors: How to Choose Custom Size Sliding Glass Doors & Custom Made Exterior Doors
Table of Contents
Patio doors have become one of the defining elements of contemporary architecture. More than simple entry points, they shape how interior and exterior spaces connect, influence the amount of natural light entering a building, and contribute significantly to both aesthetics and functionality.
Today, homeowners, architects, and developers increasingly choose custom patio doors to create unique living environments tailored to their specific design vision and performance requirements. Whether it’s a luxury waterfront residence, a contemporary villa, or a modern commercial project, custom size sliding glass doors and custom made exterior doors offer flexibility that standard solutions simply cannot provide.
In this guide, we’ll explore everything you need to know about custom patio doors, including design options, materials, performance benefits, customization possibilities, and how to choose the right solution for your project.
Why Custom Patio Doors Are Becoming More Popular
Modern architecture places a strong emphasis on openness, natural light, and seamless indoor-outdoor living. Standard door systems often limit design possibilities, especially in projects that require large openings, panoramic views, or unique architectural proportions.
This is one of the main reasons why custom patio doors have become increasingly popular in both residential and commercial construction.
Unlike standard-sized products, custom systems allow architects and homeowners to design openings that perfectly match the proportions, aesthetics, and functionality of a building. This flexibility creates opportunities for cleaner architectural lines, improved daylight access, and more personalized spaces.
Custom patio doors also improve the overall user experience by supporting smooth transitions between indoor living spaces and outdoor environments such as terraces, patios, gardens, and pool areas.
What Are Custom Size Sliding Glass Doors?
Custom size sliding glass doors are specially manufactured door systems designed to fit unique opening dimensions and architectural requirements.
Unlike standard sliding doors that are limited to predetermined sizes and configurations, custom systems can be tailored to meet the exact needs of a project. This includes:
- Larger openings
- Unique dimensions
- Specific frame profiles
- Advanced glazing options
- Custom finishes
- Specialized opening mechanisms
Custom size sliding glass doors are particularly popular in luxury homes and contemporary architecture because they allow for expansive glass surfaces that maximize natural light and panoramic views.
These systems also help create a stronger visual connection between interior and exterior spaces while maintaining thermal performance, weather resistance, and structural durability.

The Main Benefits of Custom Patio Doors
One of the biggest advantages of custom patio doors is the architectural flexibility they provide. Every building has unique design requirements, and custom systems allow architects and homeowners to achieve a more refined and cohesive final result without being limited by standard dimensions or configurations.
Custom patio doors also improve the overall functionality of a space. Because they are designed specifically around the project’s layout and user needs, they can create smoother circulation, better accessibility, and more efficient transitions between indoor and outdoor areas.
Large custom size patio doors can significantly enhance natural light and openness within a property. By maximizing glass surfaces and minimizing visible framing, these systems create brighter environments and stronger visual connections with outdoor surroundings.
Beyond aesthetics, today’s custom patio doors are engineered for long-term performance. High-quality systems provide strong thermal insulation, weather resistance, security, smooth operation, and energy efficiency, making them an important investment for both residential and commercial projects.
Aluminum Custom Patio Doors for Contemporary Architecture
Aluminum has become one of the most popular materials for custom patio doors because it combines durability, strength, and clean architectural aesthetics.
At SIMPAS, aluminum systems are manufactured using premium profiles from Reynaers Aluminium, one of the leading names in architectural aluminum systems worldwide.
One of aluminum’s greatest advantages is its ability to support slim profiles and large glass surfaces while maintaining strong structural integrity. This makes it ideal for custom size sliding glass doors that require expansive openings and minimal sightlines.
Aluminum is also naturally resistant to corrosion and environmental exposure, making it highly suitable for coastal properties and demanding climates. Combined with thermally broken systems and advanced glazing solutions, aluminum custom patio doors can significantly improve energy efficiency and indoor comfort.
Another important advantage is design flexibility. Aluminum systems are available in a wide range of finishes, colors, opening types, and configurations, allowing architects and homeowners to fully customize the final appearance of the project.
Custom Made Exterior Doors and Architectural Design
Custom made exterior doors do far more than provide access to a building. They also play a central role in shaping the architectural identity and visual character of a property.
Whether used as entrance doors, patio systems, terrace doors, or expansive sliding openings, custom systems help architects create spaces that feel more personalized, refined, and connected to their surroundings. Their ability to support unique dimensions, large glazing surfaces, and minimal sightlines gives designers far greater creative freedom compared to standard door solutions.
In residential architecture, custom made exterior doors are often used to create dramatic entrances and elegant transitions between indoor and outdoor living areas. In commercial projects, they can help establish a strong architectural presence while also supporting accessibility, durability, and long-term operational performance.
Beyond aesthetics, custom exterior doors also contribute significantly to security, insulation, energy efficiency, and user comfort. This combination of design flexibility and technical performance makes them an essential part of contemporary architecture.

Steel Custom Made Exterior Doors for Prestigious Projects
For projects requiring exceptional strength and distinctive architectural aesthetics, steel systems offer outstanding performance and design flexibility.
At SIMPAS, custom-made steel doors are manufactured using premium profiles from Secco Sistemi, a European brand recognized for innovative architectural systems.
Steel custom made exterior doors are particularly suitable for luxury residences, boutique hotels, contemporary villas, commercial buildings, and architecturally demanding projects where refined aesthetics and structural performance must work together seamlessly.
One of steel’s biggest advantages is its ability to support extremely slim sightlines while maintaining impressive durability and resistance. This allows architects and designers to create elegant openings with large glass surfaces and clean architectural lines without compromising stability or security.
Steel systems are also known for their excellent thermal performance, long-term reliability, corrosion resistance, and low maintenance requirements. Combined with thermally broken profiles and advanced glazing technologies, steel doors help create energy-efficient spaces with a sophisticated architectural character.
Custom Patio Door Configurations and Opening Types
One of the key advantages of custom patio doors is the wide variety of opening systems available for different architectural and functional requirements.
Sliding systems remain one of the most popular choices because they maximize views and natural light while minimizing visual interruptions. Lift-and-slide doors are especially suitable for large openings where smooth operation and expansive glass surfaces are important design priorities.
Folding and bi-fold systems are often selected for projects that require fully open spaces between interior and exterior environments. These configurations create highly flexible living areas that are ideal for hospitality projects, luxury residences, and contemporary open-plan architecture.
Pivot and hinged custom made exterior doors are frequently used for dramatic entrances and architectural statement pieces. Their clean appearance and versatility allow designers to create highly personalized solutions tailored to the style and proportions of each project.
Selecting the right opening type depends on several factors, including building layout, accessibility requirements, performance expectations, and overall architectural goals.

Why Professional Installation Matters for Custom Size Sliding Glass Doors
Even the highest-quality custom patio doors can underperform if they are not installed correctly.
Professional installation is essential to ensure proper sealing, smooth operation, structural stability, weather resistance, and long-term durability. Large custom size sliding glass doors require especially precise installation because of their dimensions, weight, and structural requirements.
Improper installation can lead to water infiltration, air leakage, reduced insulation performance, operational issues, and premature wear over time. In large architectural openings, even small alignment errors can significantly affect the long-term functionality and appearance of the system.
Experienced installation professionals understand how to properly integrate custom sliding systems into the building envelope while ensuring compliance with project specifications and performance standards. For high-end architectural projects, installation quality is just as important as the product itself.
