What is Turnkey Home Construction?
Turnkey home construction (xây nhà trọn gói) is a comprehensive building service that encompasses all phases of the project, from design and construction to final completion. The client only needs to communicate and agree with the contractor on the requirements and desires regarding the design, quality, and level of finishing for the project. The contractor then takes full responsibility for execution and proposes appropriate solutions.
Advantages of the Turnkey Home Construction Service
Turnkey home construction is a modern building method favored by many investors. It is a synchronized construction process, from the design phase, material procurement, construction, and interior finishing, all the way to project handover, carried out by a single professional contractor or construction company. Below are the advantages of turnkey construction that you should be aware of:
Good Warranty and After-Sales Service: Many turnkey contractors provide warranties and after-sales services after project completion. This gives the investor peace of mind regarding the project’s stability and provides a resource for support should any issues arise during the home’s use.
Saves Time: One of the biggest advantages of turnkey construction is saving time. You don’t need to worry about searching for, selecting, and dealing with various partners such as architects, general contractors, masons, electricians, plumbers, and material suppliers. The turnkey contractor will handle the entire construction process, saving you time spent on project management and monitoring.
Guaranteed Project Quality: A turnkey contractor usually has a team of experienced engineers, architects, and skilled workers, and uses high-quality building materials. This helps ensure the quality of the project from design and construction to interior finishing. The technology, techniques, and construction process applied adhere to standards, helping ensure the stability, safety, and durability of the structure.
Rational Asset Investment Value: Turnkey construction helps the investor control construction costs from the beginning to the end of the project. You don’t have to worry about exceeding the planned budget because the turnkey contractor conducts estimations, cost setting, and contracts before the project begins. Simultaneously, strict supervision by the turnkey contractor helps avoid unnecessary additional costs that might arise during construction. Furthermore, a turnkey contractor can negotiate and achieve the best material prices from partner suppliers, helping to minimize material costs and ensure a sensible investment.
Aesthetic and Design Authority: A turnkey contractor often has a team of experienced architects and interior design specialists. This means you can leverage the professionalism and creativity of the design team to have a beautiful, comfortable home that suits your needs. You can participate in the design process, give your input, and receive consultation to achieve the best possible result.
Saves Effort and Stress (Psychological Comfort): Turnkey construction reduces the effort and psychological stress for the investor. You don’t need to worry about tracking and managing many different partners, solving issues that arise during construction, or adjusting the construction schedule. All work will be handled by the turnkey contractor, allowing you to focus on your work and other daily activities.

Turnkey Home Construction Process
Step 1: Consultation and Site Survey
3A Design will create a Client Information Form. This form, developed through consultation with our architects and based on the homeowner’s usage requirements, will finalize a comprehensive information sheet detailing:
Site Survey: After the consultation and understanding the requirements, 3A Design’s architects will verify the information and directly survey the construction site.
Construction Purpose: (e.g., residential, combined residential and workspace, etc.)
Main Functions within the House: (e.g., living room, kitchen, number of bedrooms)
Prevailing Design Style: (e.g., Modern, Minimalist, Neoclassical, etc.)
Construction Budget: Based on the client’s financial requirements, we will prepare a cost breakdown for various categories such as construction, finishing, and interior design, providing the homeowner with a preliminary financial picture for the home investment.
Feng Shui Consultation: 3A Design’s Feng Shui expert will utilize a compass (la kinh) to survey the land’s position and use the homeowner’s information to provide appropriate Feng Shui consultation for the family.
- Checking planning information based on the plot number and map sheet number.
- Extracting the land title/deed to determine the precise coordinates of the plot.
- Determining building regulations through the construction permit.
- Surveying traffic to identify approach directions and internal traffic flow.
- Measuring the foundation elevation (ground level) and checking the area’s drainage system.
- Considering the house orientation and microclimate factors.
Step 2: Floor Plan Conceptual Design
Based on the information gathered during the consultation and site survey process, 3A Design’s architects will design the conceptual floor plan for the project and establish the architectural and interior design orientation for your home.
The project’s floor plan is the solution to a complex equation with many variables, ensuring the following factors: it suits the construction purpose, divides the functionality appropriately for the usage needs, the design style harmonizes with the landscape to express the homeowner’s desires and personality, the design fits the client’s investment level, and the layout ensures correct functionality. It must also align with the Feng Shui of the plot and the homeowner’s destiny/fate (cung, mệnh), feature flexible open and closed spaces, and strategically utilize the plot’s inherent factors like views, sunlight, and wind direction.
Step 3: Architectural Perspective Design
Architectural Massing Concept Design: Based on the analysis of climate, views, planning regulations, and a design style suitable for the homeowner and the usage needs of family members, we propose architectural massing concepts for the project.
Detailed Perspective Design: Once the massing diagram is finalized, the next step is the detailed perspective design for the project, covering aspects such as: materials to be used, dominant color schemes, structural details, and aesthetic architectural details.
Lighting Design: A beautiful structure is not complete if it is only stunning under daylight. Scientific and purposeful lighting design is essential to enhance the beauty of the structure during the remaining 12 hours of the day.
Step 4: Interior Concept Design
This is the initial step of the interior design phase. The objective of this design step is to align the design intent of the architect with the client’s vision.
Based on the usage requirements, the preferences of family members, the styles the client favors, and the color palettes proposed by the homeowner, the interior architects will consult and propose the dominant interior style, the materials to be used, and the selection of furniture and decorative lighting that complements the external architecture of the house.
They will develop design concepts for the functional spaces. This includes providing visual references through images so that the interior architect can clearly communicate their intent to the homeowner—showcasing how they plan to execute each internal space. This process provides the homeowner with an initial visualization of their future home.
Step 5: Interior Perspective Design
Interior design must always ensure the following elements: it is compatible with the architecture and landscape of the project, aligns with the homeowner’s preferences, meets the requirements for functionality and budget, and respects the Feng Shui of your home.
Every interior designer is a crucial piece in the journey of building a home. Therefore, understanding the homeowner and having a deep knowledge of trends, materials, and equipment used are always our foremost criteria.
Step 6: Construction Documentation Deployment
The final step in the design process is the deployment of the construction documentation. Once the design files are complete and confirmed by the homeowner, 3A Design’s engineers and drafters will deploy the full set of documents for the project, including:
- Architectural implementation drawings,
- Structural implementation drawings,
- MEP (Mechanical, Electrical, and Plumbing) implementation drawings,
- Drawings for accompanying equipment such as cameras and solar power systems,
- Implementation drawings for interior and exterior finishing,
- Interior furniture deployment drawings,
- Lighting deployment drawings, and
- Detailed technical implementation drawings.
In this step, meticulousness and carefulness in every detail are paramount, as even a minor error can affect the subsequent construction stages.
Step 7: Quotation
After the complete set of architectural and interior perspective drawings, along with the technical drawings, is finalized, the Quantity Surveying (QS) Department will perform a quantity take-off for the project. They will identify all necessary work items and calculate the estimated cost for each item. Based on this information regarding work volume and estimated costs, the QS Department will prepare the final construction cost estimate, providing all relevant parties with a comprehensive overview of the projected expenses required to execute the project.
The Quotation Process is divided into 4 main steps:
- Preliminary Quotation: This includes a financial outline based on the project’s square meter area, divided into three parts: structural works, finishing works, and interior furnishings. The purpose is to establish the basic price framework for the entire project.
- Detailed Structural Works Quotation: After agreeing on the financial approach with the client, a detailed quote for the structural phase is prepared, based on the project’s architectural and structural drawings. The quantity breakdown based on the design requires high accuracy, with materials priced according to market rates.
- Finishing Works Quotation: This covers both interior and exterior finishing. Interior finishing includes ceilings, floors, walls, and sanitary equipment. Exterior finishing includes facade materials, decoration, railings, handrails, entrance canopies, gates, etc.
- Interior Furnishing Quotation: This covers built-in furniture, loose furniture, and decorative elements. This quotation requires knowledge of material properties and costs as per the design, as well as experience in construction and engineering techniques to provide an accurate and reasonable price to the client.
Step 8: Material Selection
After finalizing the cost estimate, selecting the finishing materials for the project becomes an indispensable and crucial step. Finishing materials include the type and color of paint, and decorative cladding materials for both the interior and exterior, such as stone, tile, wood flooring, etc. This step affects the overall aesthetics and quality of the project and requires participation from the Quotation, Implementation, and Architectural Departments. Therefore, to ensure the project is completed successfully, the material selection process must be carried out carefully and with close coordination among the relevant departments Quotation, Implementation, and Architects to make the most suitable and optimal material choices.
Step 9: Construction
Once all factors related to the project including quantities, drawings, timeline, technical specifications, and materials have been agreed upon, the homeowner and the company will proceed to sign the construction contract. This is crucial for ensuring the accuracy and transparency of all information and requirements related to the project.
After the contract is signed, the construction work will be executed by the construction team and strictly supervised. This supervision ensures that processes and timelines are followed correctly, simultaneously guaranteeing the safety and quality of the construction project.
Quotation Structure
The 3A Design quotation structure is divided into four main parts, with clear and comprehensive detailed information:
1. Structural Works
This involves the house’s structural frame, with quantities derived from the architectural and structural design drawings. The structural works can be simply understood as the reinforced concrete structure, brick walls, stairs, etc., serving as the critical foundation for any construction project. The better, more accurate, and more robust the structural works are, the more convenient the subsequent construction phases will be, helping to save costs and time, and ensuring the project’s long-term durability.
2. Finishing Works
This refers to the interior and exterior “skin” of the project, such as: railings, handles, entrance canopies, cladding and tiling, plaster ceilings, interior and exterior paint, etc. Finishing works require high technical precision and aesthetic quality. Once this stage is completed, the house is ready for use.
3. Interior Furnishings
Based on the interior design drawings, 3A Design will take off the quantities for the entire house’s furnishings, divided into two main categories:
- Fixed Furniture: Items such as kitchen cabinets, built-in wardrobes, and all attached and fixed shelving units.
- Loose Furniture: Interior items that are separate and not attached to walls or built-in, such as dining tables, chairs, sofas, coffee tables, etc.
4. Equipment
This includes all electrical and plumbing equipment inside and outside the project, such as water pumps, hot water tanks, energy systems (e.g., solar), air conditioners, refrigerators, and kitchen appliances, along with sanitary fixtures.
Construction Cost Estimate
Based on the architectural design drawings, 3A Design will proceed to conduct a quantity take-off for the structural works, separating them into individual items. Subsequently, we calculate the costs based on current market material prices to produce a detailed quotation. The more detailed the quotation is, the more accurately the client’s budget can be forecasted, minimizing unexpected costs.
Based on the investor’s actual needs and the architectural and interior design of the house, 3A Design’s architectural team will collaborate with the investor to suggest equipment options that align with the budget, design, and functional requirements.
