    What is the average price of a home construction project? This is the first question most people who are thinking about self-building want answered, and for some people it's the only thing standing in the way of beginning their path. The massive projects with multi-million-pound budgets seen on television have shaped many viewers' conceptions of what it means to build one's own home (that still somehow run over). Self-building a house may seem like a high-risk endeavour, but if you do your research and plan carefully, you can find a home that fits your budget.

    Just think of all the customization options you'd have if you weren't limited to what's already available on the market. Although the option to build your own home is exciting, it also comes with a hefty price tag, often between $158,572 and $478,600 (or an average of $100 to $200 per square foot).

    Buying a new house from the current stock is a crapshoot: It's possible that a home with many desirable qualities is located in the incorrect neighbourhood for a potential purchaser, while another home in the prefered neighbourhood can be in worse shape than expected. In addition, property values can differ drastically depending on factors such as the location of the market, the state, and even the side of the street. When you construct your own home, you get to decide on every last aspect and keep an eye on the finances, at least until something unexpected comes up. In addition, when you build your own home, you get an intimate familiarity with the mechanics of the location where you will spend the majority of your life.

    Consequently, there are a wide variety of factors to consider when estimating the cost of a construction project. To assist you learn how to finance a newly made home that fits your style and budget, we have detailed the many components of home construction.

    How Much Does It Cost To Build A House?

    The process of building a home is not only difficult, but also quite costly. If you're seriously considering this endeavour, you should be aware that in addition to the obvious expenses, there are likely to be many more that you haven't yet considered.

    You should be sure you can afford to build a house from the ground up.


    You've probably previously considered this possibility. You'll need to spend a decent sum to get the materials necessary to construct your ideal home.


    This is another one you've undoubtedly considered. You can expect to pay a decent sum for the labour put in by your builders because they won't do it for free.

    Soil And Contour Tests

    One that you may not have considered is that a builder will want to run two independent tests before laying down any quotes: one on the soil, and the other on the contour of the property. If construction presents any obvious challenges on your land, you might expect to pay more. In a similar vein, constructors will evaluate the incline of the terrain. In most cases, the steeper the angle, the higher the price. Depending on how steep the drop is, you can figure on spending between $5,000 and $10,000 for every metre of horizontal drop on your property, and even more if the drop is on the side of your block.

    Site costs

    The expenses associated with the land on which your new home will be constructed are likely to fluctuate the greatest. This depends on a number of factors, including the nature of the soil and slope, the accessibility of the site, the presence or absence of trees and roots, the need for retaining walls, and any unforeseen obstacles.


    A surprising number of builders' estimates leave out the expense of installing flooring. The reasoning behind this is because you should expect to pay more for things like carpet, flooring, and tiles in addition to the expense of having your house built on the slab.


    Driveways are often excluded from construction estimates since they are not considered an integral feature of the structure. Your driveway's final price tag may change based on the method you choose for driving your car from the road to the garage.


    Since your builder is unlikely to be taking care of the landscaping, it is up to you to include the costs in your final estimate. The standard for builders is to install 15 square metres of turfing as part of the landscaping, but if you aren't ready to pay a little extra, you shouldn't anticipate an oasis.

    Considering Natural Disasters

    This one may seem harsh, but it could end up costing you money if you plan on constructing in a region that is more likely to be affected by natural disasters. For instance, if you're planning on constructing a home in a flood-prone region, you may need to account for the possibility of a 1 in 100-year flood when drawing up the plans. Similarly, if your property is located in an area prone to bushfires, you may be required to get a Bushfire Attack Level rating. It goes without saying that there will be extra fees for any necessary evaluations or alterations.

    Land Registration

    If you're constructing a home on recently distributed land and running utilities like plumbing and electricity, you can be affected by this.


    That's just right! You have to pay for everything, including a simple trash can on wheels. When you're ready to move in, contact your city hall to arrange for a set of bins to be delivered to your house.

    Fees For Road Closures And Disruptions

    Is there going to be a time when you have to shut down a road segment to make room for cranes or other machinery? That won't come cheap. Local governments and sometimes state governments will issue fines if you cause trouble on their streets.

    Design Modifications

    It's also a given that some problems may arise during construction, necessitating changes to the original blueprints. The extra time and effort required to make the changes, as well as the expense of hiring a professional architect or surveyor and possibly resubmitting plans to the local government for approval, can all add up to a hefty sum. Get ready for these "emergency" situations.

    Fees For Construction Loans

    The number of times you'll have to make a payment on your loan during construction is cut down by making interest-only instalments. Some of your mortgage charges, such as additional appraisals or draw-down (progress payment) fees, could be related to the construction of your home. During your consultation with a mortgage lender, they will go through all of the costs and expenses you can expect.

    How To Calculate How Much It Costs To Build A House

    The price of a house to be built is difficult to predict due to the various factors that affect the final price. Each level of construction and quality can be found in an affordable to extravagant price range, making the final cost and budget for each level entirely up to the builder.

    Even if you decide to work as your own contractor, constructing a new building involves navigating a complex web of rules and regulations and performing a delicate balancing act. Next, if you aren't going to be working on the construction site full-time, it's probably a good idea to look into general contractors and potentially hire one to oversee the entire build. You may be set on building the house on your own, but a reliable contractor can help you avoid costly mistakes and save money. Hiring a contractor will add 10% to 20% to the cost of the job, but it could prevent you from making costly mistakes. The contractor will then be able to provide you with more accurate cost estimates once this has been verified.

    Start by picking and adding the following to get an idea of how much it will cost to construct a house:

    1. The cost can be estimated if you know the house's dimensions and footprint. Planning ahead as much as possible will help you save money on supplies and labour when working with an architect. Alterations made at the last minute often result in a hefty price increase. The average price to build a new home is $150 per sq foot, but in high-end markets that amount can rise, so it's important to get multiple estimates before making any major material purchases.
    2. Find out how much it will cost to remove trees, dig holes, level the ground, do a soil test, and hook up to the city's water and sewer systems.
    3. If you need a foundation for your home, make sure you compare prices for digging the hole, hauling away the dirt, and laying the concrete.
    4. Using the square footage and diagrams of the room division plans, a contractor will be able to help you estimate the cost of framing materials and labour.
    5. Choose your prefered exterior cladding (which may involve insulation and siding options) and then shop around for offers and prices. There is a wide variety of pricing from cheap vinyl siding to moderately priced wood siding to high-end bespoke finishes like natural stone and stucco, so you can make substantial material cost savings based on your tastes and selections. Also, depending on the supplier and the quantity of the material you require, you may be able to negotiate a lower price. Determine the cost of various window options based on your design.
    6. Think about the house's major systems, like its electricity, gas, HVAC, plumbing, and technological wiring. Add up the price of all the parts you need, from the breaker box and metres to the boiler or furnace and condensers, and don't forget the wiring, switches, and other electrical accessories. Seek multiple estimates and make sure that regardless of whether the estimates provide a flat project cost, including materials, they itemise individual material costs and labour separately because the labour required to set and install these systems can be expensive and unpredictable depending on the systems you choose and regional variations in labour costs.
    7. Installation costs and material prices for interior finishes like flooring, drywall, cabinets, and ceilings will change depending on your preferences and the size and shape of the surfaces you need to cover. This figure can be determined with the aid of estimates.
    8. Permits. Every stage of a new construction project involves a permit and an inspection, and skipping one might cause significant problems down the road. To find out what permissions you need and how much they will cost, you can contact your local assessor, survey office, or municipal office.
    9. Other professional expenses. An estimate of 10% to 20% more would be added to your budget if you hired a general contractor. Professionals in the fields of architecture, engineering, drafting, and design typically work on an hourly basis, with their rates being adjustable depending on the scope of work required. Contractors should be interviewed and bid on before being hired, and the resulting cost should be factored into the overall budget.

    Factors To Consider When Estimating The Cost Of Building A House

    Once builders have a firm grasp on the essential systems and frameworks that must be in place during construction, they are in a better position to make the sorts of choices that will allow them to give priority to the features of the home that are most meaningful to them while still staying within their budget constraints. Just because something is the national average doesn't mean it's the best way to design a house. While some builders place a premium on indoor/outdoor flow, others prioritise guest bedrooms, and yet others prioritise garage space. Total price will be determined by these criteria and the competitiveness of the regional market.

    Size And Shape

    Naturally, the larger the home, the higher the price tag will be. However, this is not a simple math problem. Due to the savings in foundation, land preparation, and roofing expenditures, a two-story home with a smaller footprint may be more cost-effective than a bigger one-story home of the same square footage. Still, the whole price will depend heavily on the form: Framing,  and finishing materials, as well as labour, increase with the number of exterior corners and unusual angles. The cost of framing and constructing a spherical room means that if you want a round library room in the corner of the house, you might have to cut corners somewhere else.

    Design Features

    Your way of life includes outdoor activities? Do you want or need an outside living space such as a deck, patio, pool, or kitchen? Including these amenities from the start may save money on design, materials, and labour costs compared to adding them on afterwards. Products and services may be marked down in price to account for the inclusion of labour and materials in the overall project budget. You can save money on these luxuries if they aren't your top priority and use that extra cash for something else in your life.

    Number Of Stories

    The design and construction costs of a two-story home may be more than those of a one-story home of the same square footage, but they may be lower. For instance, larger single-story homes require greater foundations and additional roofing, whereas multi-story homes need different types of framing on the basement and first-story levels to help the second or third stories. Many first-time homeowners have a firm preference for a specific design aesthetic when it comes to their new house, making this decision an absolute need. Some people don't care how the space is divided up as long as they don't have to pay more than they have to, so they'll go with the cheaper alternative.


    Depending on their depth and whether or not they are finished, basements can increase the cost of a new home by $10 to $100 per square foot. Many communities have ordinances that limit the depth of a basement as well as the number and kind of egress points required, so it's crucial to verify with such regulations before digging a basement. These factors should not be disregarded because installing additional exits after a finished basement has already incurred a substantial financial investment.

    Geographic Location

    The cost of construction is higher in some locations than in others. The total price tag will be affected by the city and state in which construction is to take place because of factors such as the expense of transporting supplies, the accessibility of skilled labour, and the market value of these services, among others. More money will be needed for transport and labour to account for the longer distance utilities may need to be extended and the longer distance from the site to the new house if it is located in a very remote area.

    Material Costs

    The price of building supplies typically accounts for half of a home's total price tag. However, this also means that the builder's choices can affect the final price. Vinyl siding, on the other hand, is approximately $2 per square foot, while bespoke stone can cost more than $30. Therefore, it is possible to choose cost-effective materials without compromising on either security or aesthetics, freeing up resources for more pressing concerns. Construction projects require a wide variety of supplies, including the obvious drywall, flooring, wood, concrete, siding, and roofing as well as insulation, seemingly limitless amounts of wiring and pipes, nails, staples, and other gear.


    It's not cheap to pay for professional architects, builders, electricians, plumbers, interior decorators, and cleanup crews, not to mention the expense of materials. Subcontractors and specialists will use 30%-60% of the total budget, depending on the scope of the project, the design of the house, and the building materials selected. So, the time and effort required to install a basic hardwood floor will be far less than that required to install a mosaic tile floor in an elaborate design. Some finishing tasks can be done by skilled individuals to save money, but professionals should handle larger projects like whole-house systems and framing.

    Frequently Asked Questions

    You should be informed of the specifics of the construction process and the time frame in which you may expect outcomes. People who are selling their house or nearing the end of their lease will benefit greatly from having a solid schedule in place.

    Understand that delays are common in the construction of any new house, but rest assured that your builder will be able to provide you with an estimated completion date. It may take up to 45 days in advance to secure the necessary permits.

    Some companies may not consider alternatives to pre-existing floor designs when constructing a new home. As a result, you won't be able to share your vision for the house during the design process. It is unnecessary to settle if realising your ideals is a top priority. Find a business that can cater to your needs by making phone calls.

    If you're concerned about your home's carbon footprint, it's important to inquire about the availability of energy-saving options during the building process. Heating, ventilation, air conditioning (HVAC), doors, windows, and insulation are all major issues.

    It would be best if you tried to estimate the full price and the time frame in which you will have that estimate. Determine if an escalation of costs clause is included in the agreement. If the builder incurs any unexpected expenses for labour and supplies, they will be able to pass those costs forwards to the client under the terms of this paragraph.

    In some states, custom home builders are required to hold licences, while in others, this is not the case. Despite this, it is beneficial to ask prospective custom home builders questions regarding their licensing and insurance coverage.
