We all adore our homes, and we find it difficult to imagine ever leaving a place we have come to cherish. However, there can be a period when we go through life events that lead us to recognize that our home might be too tiny. Perhaps a new family member is on the way, or perhaps you simply want to turn your visions and new home inspirations into a reality. If so, building an addition to your current house can be a better option for you than finding a new place to live.

Adding a home extension could be affected by factors like the age of the house, model upgrades, and the like. Upgrading your existing home could save money and a lot of time rather than moving into a new property. Whatever is the case, the first thing you need to consider is to hire a general contractor to help and assist you with the necessary requirements before the start of the construction project. This includes building permits and being aware of the local building codes. Philippines architects and home builders include everything from supplies, labor, and transportation in addition to their professional fees for a sample house construction cost estimate.

What are the common home additions and how much does it cost?

The cost of any house addition depends greatly on the type of room. The most significant factor affecting the cost is the size of the addition and its complexity. Larger additions with multiple rooms or stories will generally cost more than a small, single-room addition. Its purpose also affects the cost. For example, expanding the bathroom requires materials to work in the existing plumbing. Below are the list of the common home additions per room including the cost guide.

New room addition

• Cost: Per square foot, the cost of an additional room ranges from 5,500 to 11,000 pesos. While the estimated final price for a standard 200-square-foot room can cost up to 2.2 million pesos.

This is the simplest home addition, and by that it is also cost-effective. A new room may or may not be an extra bedroom but could also be a walk-in closet, a home office, family room, or just a spare room. If you have in-laws who come over most of the time, in-law suites can be a great addition.

In building a new room or expanding an existing room, you must decide if you are going to build out or build up. Both of these require necessary requirements like an extra foundation on the first floor, and you’ll also need a permit to expand the size of your property. If you are planning to add a second story addition, you should also coordinate your local governance with any building-height regulations that your city may have.

Laundry room

• Cost: You’ll pay as low as 71,500 pesos for simple upgrades like flooring or appliances and as high as 825,000 pesos if you are looking to expand the room.

Adding a designated space for doing your laundry is essential where you can fold, hang, and treat your clothes. Since most laundry rooms are about 35 square feet, the price per square foot is an average price of 13,000 pesos. However, this price does include new outlets, countertops, flooring, cabinets, and even new appliances. You can reduce this cost by omitting some changes, such as new cabinets or flooring.

Increasing the size of a laundry room won’t significantly raise the cost because the laundry machines are the major attraction. Even if the space needs to be doubled in size to 70 square feet, you’ll probably simply need to spend extra money on flooring and paint rather than additional outlets and appliances.

Bathroom addition

• Cost: The total budget you will be needing for adding a bathroom ranges from 825,000 to 3,000,000 pesos. The common cost includes rough-in plumbing, shower, bath tub, and the like.

The type of bathroom you add will determine not only its approximate size but also the features it needs to contain. If you are aiming for a luxury bathroom, it requires between 100 and 160 square feet and is filled with high-end materials and fixtures. They frequently have jetted tubs, steam showers, or walk-in tub and shower combos and tend to have a spa-like ambiance. They are priced from 2,000,000 and 10,000,000 or more.

Sunroom addition

• Cost: The average cost of sunroom addition cost 11,000 to 20,000 per square foot. For a standard square footage of 200, the total cost is around 2.2 million to 4 million pesos. But if you have an existing structure for the sunroom, it can be lower, around 500,000 to 1,000,000 pesos.

Though a four season room addition is not usually common, adding a four season sunroom in our country could be quite an essential if you want to have a designated space with natural lighting. It also adds up to the mood or ambiance of the house. The materials selected have a significant impact on the price of a sunroom. Sunrooms are frequently constructed from wood, vinyl, or aluminum, with wood being the most expensive material and aluminum the cheapest.

What are the factors that add up to the home addition cost?

Labor costs

A significant portion of your budget will be for the wages of the workers including the carpenters, plumbers, electricians, engineers, and general contractor labor costs.

Electrical wiring

A professional is required to do this job. An extended electrical system typically cost around 5,000 to 10,000 pesos. While a new system for your detached addition like a detached garage will cost up to 100,00 pesos.

Building materials

The choice of materials for the addition will significantly impact the cost. High-end finishes and materials will drive up expenses, while more budget-friendly options can help you save money.

Drywall costs

To finish the interior of your addition, you’ll need to add drywall to the frame. It provides a smooth, paintable surface for finishing and is relatively easy to install. It typically ranges from 13,000 to 20,000 pesos. While the framing costs are also an additional expense.

New foundation

If your addition does not have an existing foundation and requires a new foundation, this can add a substantial cost to the project. The type of foundation which could be slab, crawl space, or full basement will affect the construction costs.

Conclusion

Now that you have an idea of a home addition cost, you might be reflecting on all the work and expenses. Working on all the necessary requirements like the building permits and other site preparation process including purchasing of building materials might be quite a hassle. If you do not have all the time and patience to expand and renovate your old home, you can always find the perfect home especially here in Brittany.
