It can be said that single-story houses are the most common type of house in Vietnam, especially in rural areas. With reasonable construction costs, suitable for the budgets of many families, single-story houses are a great choice for those who need to build a house.
In this article, 3A Design will introduce to readers some beautiful and affordable single-story house designs costing around 300 million VND. With these designs, you can build a spacious and comfortable home without spending too much money.
What is a Single-Story House?
A single-story house is a type of house with only one floor. It is typically designed with a main entrance leading to the common living space, one or more bedrooms, a kitchen, a bathroom, and a front or back yard. Single-story houses usually have a smaller built-up area compared to multi-story houses, which helps reduce construction and maintenance costs. Although single-story houses have a simple design, they offer flexibility in customization and improvement to meet the needs of the family. This type of house is often preferred due to its affordability and ease of maintenance and repair.

Why 300 Million VND Single-Storey Houses Are So Popular
Affordable single-storey houses have become one of the most popular choices in today’s real estate market. This budget range is especially attractive to those who want to own a home without facing overwhelming financial pressure. Below are the key reasons why 300 million VND single-storey houses are widely favored.
Affordable Pricing
Affordability is the primary factor that makes budget single-storey houses appealing. With an estimated cost of around 300 million VND, individuals and families with low to middle incomes can achieve homeownership without taking on excessive financial burdens.
Lower Construction and Maintenance Costs
Single-storey houses typically have a smaller construction area compared to multi-storey homes. This significantly reduces initial construction costs as well as ongoing maintenance expenses. This advantage is particularly important for homeowners building for investment purposes or for long-term family living.
Easy Maintenance and Repairs
Thanks to their simple, single-level structure and the absence of complex elements such as staircases, single-storey houses are much easier to maintain and repair. This helps homeowners save both time and resources throughout the house’s lifespan.
Suitable for Narrow or Limited Land Areas
For plots with limited or narrow land area, single-storey houses provide an efficient solution. This housing model allows homeowners to maximize land use while still creating a comfortable and functional living space.

Advantages and Disadvantages of 300 Million VND Single-Storey Houses
Advantages of Affordable Single-Storey Houses
Low construction cost
One of the biggest advantages of single-storey houses is their lower construction cost compared to multi-storey homes. With a smaller floor area and a simple structural design, this house type helps reduce expenses on construction and building materials—making it ideal for budget-conscious homeowners.
Efficient land use
Single-storey houses are well suited for small families or limited land plots. With only one level and no need for staircases or elevators, this model allows homeowners to use land more efficiently while still leaving space for a garden or outdoor area.
Disadvantages of Affordable Single-Storey Houses
Limited living space
With only one floor, single-storey houses offer less living space than multi-storey designs. This can limit family activities and reduce privacy, especially as household needs grow over time.
Functional limitations
Single-storey houses have restricted flexibility in space division. Functional areas such as the living room, bedrooms, and kitchen may lack clear separation, making interior arrangement more challenging and reducing overall spatial efficiency.
Not suitable for large families
Due to their compact size and limited layout options, single-storey houses are generally not ideal for large families. Accommodating multiple bedrooms and shared living spaces can become inconvenient for daily life.

A mezzanine single-storey house is an excellent solution for families who need more usable space. Thanks to the mezzanine level, homeowners can add extra functions such as additional bedrooms, a home office, or a shared family area without significantly increasing construction costs.
