Construction Company Scotland, Before you start planning a house extension, it’s important to get planning permission and know about the costs involved. After that, you need to think about the design and materials. You’ll also need to get the right planning permission from your local council and discuss your requirements with your neighbours. Ultimately, your house extension should be a practical addition to your property. Taking these steps will ensure your house extension is safe, attractive and fits in well with the rest of your home.


The cost of a house extension is dependent on many factors. Bigger extensions tend to cost more, as they require a higher amount of material and labor. You also have to consider where you live. In urban areas, the cost of extending a home is higher than in rural areas. The type of soil also affects the cost. You should not compromise on the quality of the groundwork to save money, and make sure to factor this into your budget. Moreover, if you plan on extending your home, you must also take into account the cost of removing landscaping and patios.

While building a home extension, it is important to consider the costs before starting the project. For example, kitchens and bathrooms tend to cost more than other rooms. This is because kitchens and bathrooms have more complicated requirements and require more labour. Furthermore, these rooms also often require additional building consents. You can save money by choosing to re-use existing materials or avoiding new fixtures and appliances.

The cost of building a house extension depends on many factors, including the size of the extension and the location of the house. A single-storey extension will cost between $1,350 and $2,100 per square foot, while a two-storey extension can cost as much as 50% more than a single-storey extension.

The costs of a house extension will depend on several factors, such as the type of project, the materials used, and the size of the home. For instance, a small bump-out is cheaper than a large ground-floor extension, as it requires less land. A mudroom extension will cost anywhere from $3,600 to $7,200. A mudroom extension will cost more if you plan on adding closets and a door. You should also consider the costs of internal finishes, heating and cooling, and structural changes.

Planning permission

If you want to build an extension on your house, you need to apply for planning permission. This can be tricky, and it’s better to hire an architect or builder who can advise you on the legalities. Some aspects of the extension process are contentious, such as adding balconies or opening the side elevation to the garden. Then, you need to consider what materials you want to use to create the extension.

Some home improvements don’t require planning permission, such as loft conversions, porches, and single storey house extensions. However, others require planning permission. This depends on the use of the space, such as for a study or home gym. There are also certain restrictions on building the structure, such as a balcony or veranda.

You should also consider whether your house is listed or not. A listed building cannot be redeveloped without planning permission. If you live in a conservation area, you will need to apply for listed building consent and planning permission. Failure to do this could land you in trouble with large fines and even imprisonment. A lawyer can help you understand the rules and regulations.

Planning permission is usually valid for three years. If you want to extend your house, you should get permission before the three years are up. You can also apply for a renewal if needed. In the past, you could also pay a small fee to your local planning authority if you needed to extend the time.

When you receive your planning permission, you should know what to expect from the process. You should make sure that you are prepared and have all the necessary information ready. It is also important to ensure that your plans don’t violate any planning rules.


A design of house extension can enhance the existing features of a home. It is similar to renovation, but focuses more on expanding a current build. The design process should consider the available budget and long-term goals. The homeowner should also consider their expectations for the new build, and work with a building designer to create a design that meets those needs.

The planning rules and nature of nearby buildings will also influence the design of the extension. A contemporary design is easier to gain planning consent for than a more traditional one. Moreover, two-storey side extensions must not have windows that overlook the back gardens of neighbours. If you’re not sure how to obtain planning permission, consult a professional architect.

Before you make any decisions about the design, consult an architect or a builder. A preliminary plan can help you obtain an estimate for the project. By knowing the cost of the extension, you can decide if it is affordable. In addition, consider the insurance cost, which will depend on a number of factors.

When choosing a building designer, you can also ask for references and portfolios. You can also ask to see some of the designs in person. While you’re interviewing candidates for a house extension project, make sure that they’re capable of delivering the design you’re looking for. Construction Company Scotland, You don’t want to be overwhelmed by a design company’s impressive work. Instead, you want to trust your instincts and feel confident that the designer will deliver what you want.


Buying materials for house extension yourself is a great way to cut costs. Typically, builders will add a percentage of the cost of materials to the total price of the project, but you can save money by sourcing the materials yourself. For example, if you’re building a two-storey extension, you can buy timber or blockwork, which both cost roughly the same.

While brick and stone are the classic choice for house extensions, you can also use materials such as wood, copper, and glass. Each of these materials has different qualities and creates different visual effects. They can also be used in small or large projects, and they can also be a good fit for different budgets. Dark metal cladding, for example, looks modern but is practical and plays well against the brick of the original building.

When designing a house extension, you should also consider the size of your house’s footprint. The total floor area of an extension should not exceed 50% of the existing house’s floor area. It should also not eat into too much of your garden. Construction Company Scotland, This might impact your home’s future saleability.

A basic extension can cost between $1,400 and $1,800 per square meter, depending on location, complexity, and finish. These costs typically include all of the building elements essential to the construction, including foundation, walls, and a subfloor. Basic electrical wiring and plumbing aren’t included in this cost.

Building regulations

If you want to add extra space to your home, it is important to follow the building regulations. You must comply with height and width restrictions and the design must complement the rest of the property. You must also follow the planning permission requirements. If you do not have the necessary planning permission, you may be unable to carry out your new project.

You should also follow the fire regulations when building an extension. Construction Company Scotland, Most extensions must meet fire safety standards, which mean using inert building materials. These materials are resistant to fire for at least 30 minutes. You should also consider fire hoods, which protect major structural components. Fire-rated plasterboard wall panels are available today, as well as integral cavity barriers.

Unless you have the necessary permission, you should consult your local building control or an approved inspector before starting work. Performing the wrong works can lead to fines and a call for demolition. Similarly, if your extension will affect the neighbouring property, you must seek their consent. Construction Company Scotland, This can take time and costs. It is therefore best to consult early with the neighbours if you intend to extend your home. And remember: the planning process is lengthy.

Before you begin a house extension project, make sure you know the building regulations. The rules are complex and cover many areas. A structural engineer or architect will be able to compile the rules into detailed drawings that the contractor can follow during the construction phase. Your architect will also be able to assist you during the planning process.

You should also understand the difference between a Planning permission and a Building Regulation approval. Some types of building work, such as a garage extension, require both.
