Tirta Gardens — FAQ

Tirta Gardens specializes in designing and building custom water features and tropical gardens in Bali for villas, resorts, and developers. From koi ponds to natural swimming ponds, andesite stone to tropical plants, we offer comprehensive services tailored to Bali’s climate and your vision.

How much does a water feature or koi pond cost in Bali?

The cost of a water feature or koi pond in Bali can vary widely based on several factors, including size, design complexity, materials used, and site-specific conditions. Each project is unique, and we recommend a site visit to assess your specific needs and provide a detailed quote. Generally, you can expect costs to cover design, excavation, materials, labor, and installation. For koi ponds, additional considerations include filtration systems, aeration, and predator protection, which are crucial for maintaining a healthy environment for the fish. We emphasize using quality materials like Bali andesite and paras stone, which suit the tropical climate and ensure durability. Our team is ready to assist from the initial consultation to the final handover, ensuring that your investment results in a beautiful and functional water feature tailored to your property.

Do you design and build, or only build to someone else’s design?

At Tirta Gardens, we offer a comprehensive service that includes both design and build. Our experienced team is skilled in creating bespoke water features and tropical gardens tailored to your vision and the unique conditions of your site. We work closely with you from the initial concept stage, ensuring that the design aligns with your aesthetic preferences and functional requirements. However, if you already have a design from an architect or designer, we are also happy to collaborate and bring that vision to life. Our flexibility in approach allows us to cater to a range of client needs, whether you’re looking for a complete design-build service or need expert builders to execute an existing plan. Our craftsmanship and attention to detail ensure a seamless integration of design and construction.

How do koi pond filtration and water quality work in the tropics?

Maintaining water quality in a koi pond in Bali’s tropical climate involves a combination of mechanical and biological filtration systems. Mechanical filtration removes debris and particulates, while biological filtration uses beneficial bacteria to break down harmful ammonia and nitrites. Adequate aeration is crucial to support these bacteria and to keep oxygen levels optimal for the fish. The pond should be deep enough to help regulate temperature and provide a stable environment. Regular water testing and filter maintenance are essential to monitor parameters like pH and ammonia levels, ensuring a healthy habitat for your koi. Additionally, providing shade and predator protection helps maintain a balanced ecosystem. Our designs incorporate these elements, tailored to the tropical conditions, to ensure that your koi pond remains vibrant and healthy.

What is a natural swimming pond, and is it chlorine-free?

A natural swimming pond, or bio-pool, is a chemical-free swimming option that uses a planted regeneration zone for biological filtration instead of chlorine. This design creates a natural look and feel, blending seamlessly with the surrounding landscape while providing swimmable water. The pond is divided into zones: a swimming area and a planting area, where aquatic plants help filter and clean the water. The biological filtration system mimics natural processes, using beneficial bacteria to maintain water quality. This eco-friendly approach suits those looking for a sustainable and aesthetically pleasing alternative to traditional pools. Proper design and maintenance are crucial to ensure the zones function effectively, keeping the water clear and inviting. Our team has the expertise to design and build bio-pools tailored to your property and preferences.

What stone and materials do you use in Bali?

In Bali, we primarily use local materials that suit the tropical climate and offer durability and aesthetic appeal. Common materials include Bali andesite and paras stone, both volcanic stones known for their strength and natural beauty. These stones are ideal for water features, pathways, and hardscaping due to their resistance to weathering. We also use river rock, concrete, terrazzo, and ceramic, each chosen for specific applications based on their properties. Water-resistant finishes are applied to protect surfaces exposed to water and humidity. Our craftsmanship honors Balinese stone-carving traditions, ensuring that each element of your garden or water feature is both functional and artistically executed. Selecting the right materials is crucial for longevity and visual harmony with the surrounding environment.

Do you work with villa builders, developers and architects?

Yes, we frequently collaborate with villa builders, developers, and architects to integrate our water features and landscaping into larger projects. Our expertise in tropical design and construction complements architectural visions, enhancing the overall aesthetic and functional experience of a property. We understand the importance of seamless coordination and communication in multi-disciplinary projects and are committed to working closely with your team to achieve the desired outcome. Whether it’s designing a bespoke water feature for a luxury villa or implementing a comprehensive landscaping plan for a resort, our goal is to add value and beauty to your development. Our process accommodates both bespoke design-build projects and executing pre-designed plans, ensuring flexibility and precision in delivery.

How long does a typical project take from design to handover?

The timeline for a project from design to handover varies based on its complexity, size, and specific requirements. Generally, the process begins with an enquiry and site visit, followed by the concept and design phase, which can take several weeks depending on revisions and client input. Once the design is finalized and approved, we provide a detailed quote and timeline for the build phase. Construction and planting can range from a few weeks to several months, influenced by factors like weather conditions and material availability. Throughout the process, we maintain clear communication to ensure that timelines are met and expectations are managed. Our goal is to deliver a high-quality water feature or garden that meets your vision and stands the test of time.

Do you offer ongoing maintenance for absentee villa owners?

Yes, we provide ongoing maintenance services tailored to the needs of absentee villa owners. Our maintenance plans cover essential tasks such as water quality testing, pump and filter servicing, plant care, and seasonal upkeep to ensure that your water features and gardens remain healthy and visually appealing year-round. Regular maintenance is crucial in Bali’s tropical climate, where heavy rains and strong sun can impact water levels and plant health. Our team is equipped to handle these challenges, offering peace of mind that your investment is protected and well-maintained in your absence. We can customize our services to suit your specific requirements, ensuring that your property remains a beautiful and tranquil retreat whenever you return.

What plants suit a low-maintenance tropical Bali garden?

For a low-maintenance tropical garden in Bali, selecting the right plants is key. We recommend using hardy species that thrive in Bali’s climate and require minimal care. Popular choices include frangipani, heliconia, various palms, and ferns, all of which offer lush foliage and vibrant flowers. These plants are well-adapted to the tropical environment, tolerating both the wet and dry seasons with ease. Ground covers like mondo grass and native grasses help reduce weed growth and maintain soil moisture. Incorporating a well-designed irrigation system further reduces maintenance needs by ensuring consistent watering. Our plant selections focus on creating a balanced ecosystem that supports local biodiversity while providing aesthetic appeal with minimal upkeep. We tailor our plant choices to suit your garden’s specific conditions and your preferences.
