Types of Home Extensions
A single-storey extension is an excellent option if you need more living space or want to create an open-plan living area. It can be built at the side, front, or rear of the property, depending on your requirements.
A double-storey extension is ideal if you want to add more bedrooms or bathrooms to your home. It can also be used to create a larger living area on the ground floor.
A conservatory is a cost-effective way to add more living space to your home. It is a glass structure that can be used as a dining room, playroom, or home office.
An orangery is similar to a conservatory, but it has a solid roof and brick walls. It is more expensive than a conservatory but provides better insulation and can be used all year round.
Factors to Consider when Planning for an Extension
Before embarking on a home extension project, there are several factors that you need to consider.
You will need planning permission from your local council before building an extension. The rules for planning permission vary depending on the size and location of the extension.
Extensions can be expensive, and it is essential to have a realistic budget in mind before starting the project. You should consider the cost of materials, labour, and any additional expenses such as planning permission fees.
The design of your extension should complement your existing home and meet your specific requirements. You may need to hire an architect or designer to help you create the perfect design.
You will need to comply with building regulations when building an extension. These regulations ensure that the extension is safe, energy-efficient, and meets certain standards.
Home extensions are a great way to add more living space and value to your home. Whether you choose a single-storey extension, double-storey extension, conservatory, or orangery, it is essential to consider the factors mentioned above to ensure that your extension meets your specific requirements and complies with building regulations.
