Indoor–Outdoor Living in the Gulf | Climate, Shading and Landscape | Nellis Architecture

Indoor–outdoor living is more than a design preference in the Gulf. It is a way of inhabiting the landscape, using architecture to soften the extremes of climate while drawing people closer to nature. The challenge is familiar. Summers are intense. Winters are extraordinary. A home must therefore adapt, opening fully in the cool season and protecting comfort during the hotter months without losing atmosphere or connection.   For our studio, indoor–outdoor living is not about spectacle. It is about balance, clarity, and craft. It is the art of creating seamless transitions between interiors, shaded terraces, gardens and courtyards, using architecture as a mediator rather than a barrier.   “Indoor–outdoor living only works when architecture, landscape and climate systems speak the same language,” says Lee Nellis, Principal Architect. “You cannot rely on one element. It has to be a complete, responsive environment.”  

Opening the Home: Slim Sliding and Pivot Glazing

  At the heart of Gulf indoor–outdoor living is the ability to open the facade completely during the winter. Slim sliding or large pivot glazing systems allow living rooms, dining spaces and family areas to dissolve into terraces, creating a single continuous landscape.   Precision engineering matters. Frames disappear. Thresholds drop flush. Mechanical tracks are hidden. The aim is not simply openness, but effortlessness.   “When glazing is designed well, it feels weightless,” explains Ashley Bothma, Senior Architect. “The movement is smooth, the sound is minimal, and suddenly the whole atmosphere of the home changes.”   Openable facades also redefine how spaces are used. A living room becomes a majlis in the early evening. A dining room becomes a garden pavilion. Family areas extend toward water features or shaded courtyards without feeling exposed.  

Materials That Endure the Gulf Climate

  The Gulf demands materials that perform. High heat, UV exposure, humidity and occasional sandstorms create conditions where only certain finishes survive long-term. We often specify:  

• Timber for warmth and tone, carefully treated for humidity and temperature swings
• Limestone cladding for natural colour variation and breathable performance
• Travertine for floors and terraces, non-slip and cool underfoot
• Granite for durability in high-contact areas
• Aluminium for shading elements, screens and window systems, resistant and light

  “These materials age with dignity,” says Margaret Pluta, Landscape Architect. “They handle heat, salt and sand, and they blend naturally with greenery and water.”   The palette becomes part of the indoor–outdoor narrative. Nature flows into the home not only through openings, but through texture, colour, and the unique variation of stone and timber.  

Cooling and Comfort Technologies

  The magic of indoor–outdoor living in the Gulf comes from invisible engineering. To make open-plan spaces usable even in the warmer months, homes must rely on integrated cooling and air movement strategies.   This often includes:

• Hidden VRF systems
• High-performance wall insulation to complement all systems

Thermal comfort is never an afterthought. It is engineered into the architecture from day one.  

Shading: The Gulf’s Most Underrated Design Tool

  Shading is not an accessory. It is a necessity. External canopies, deep overhangs, screened verandas and operable louvers reduce heat gain by shaping light long before it enters the interior. Shaded outdoor rooms remain usable for months on end, turning terraces into real living spaces.   Effective shading also adds atmosphere. Light becomes softer, shadows longer, and the quality of the space becomes more calming.    

Landscape as a Cooling Strategy

  Indoor–outdoor living in the Gulf relies on landscape as much as architecture. Trees cast shade, water features cool the air, and planting softens boundaries between interior and exterior.   Landscape is not decorative. It is environmental performance. Margaret explains, “When trees, water and stone are positioned intentionally, they cool the microclimate and make outdoor rooms genuinely comfortable. It is one of the Gulf’s most timeless cooling strategies.”   Landscape also creates emotional texture. The sound of water, filtered light through branches, the scent of planting after irrigation. These sensory elements turn transitional spaces into places where people linger.  

A Living Threshold

  Indoor–outdoor living is a living threshold rather than a static feature. It evolves with the seasons. It adapts to how families gather, host and unwind. It responds to climate without sacrificing comfort. It elevates architecture beyond enclosure and into experience.   For Nellis Architecture, the aim is simple. Create homes that feel connected, breathable and calm. Homes that allow nature to be felt, even in the Gulf’s extremes.   When the architecture opens, the landscape answers. When the climate shifts, the home adapts. And when everything is designed with intention, the boundary between inside and outside becomes beautifully thin.
