10 Extension Ideas for Semi-Detached Homes

Each house has its design and layout, so its extension must be compatible with the rest of the building. Here is a list of common and useful home renovation solutions if you are planning an extension.

Single-Storey Rear Extension

Rear extension to semi detached house is one of the most popular options to increase the area of the house or create a spacious additional room. The basic advantage of the solution is that it does not require a permit in many regions. However, the exact answer to the question depends on the municipality, so it is better to get a comprehensive consultation before starting the renovation. Single-storey extensions are easy to add and can make your home more convenient and welcoming from the outside. They will steal some of your garden and seating space, but can increase light penetration or provide panoramic views when sliding glass frameless doors are installed. The structure can serve as a kitchen, living room, recreation area, or interior garden.

Side Return Extension

Most semi-detached houses have some free space on the side. You can turn it into an extension and use the area to expand the existing rooms. Side extensions are a modern option for modernizing buildings that are inexpensive and do not require much time to build. They are usually small but can make your home more comfortable without affecting the garden. They can be one or two storeys and have different configurations. This extension can also serve as a wide terrace for gatherings.

Wraparound Extension

It is an extension that combines two ideas into one. It involves the side and rear areas around the house and forms an L-shaped extension. This design is intended to expand a room or add another one, smooth the transition to the garden, or organise a spacious dining or living room. The main advantages of this option are the low use of the garden and a wide range of arrangement methods. It adds space and light and can dramatically improve the look of the house.

Double-Storey Extension

A two-storey extra building is one of the most suitable extension ideas for semi detached houses, provided you need to significantly increase the space or add several rooms at once. It can be built on the side, front, or back of the house and often requires getting the permits. To add a double-storey construction, you need to develop a detailed project that takes into account the specifics of your and your neighbour’s house. In addition, it is better to implement such a plan with a team of professional engineers and architects. The benefits of the solution are obvious. It is an extension of several full-fledged rooms that provides a lot of living space, light, and can positively affect the layout of the entire house. The additional rooms you get can become bedrooms, guest rooms, playrooms, or children’s rooms.

Loft Conversion

Most lofts have no practical use, so they often serve as a collection of unnecessary things. However, almost any loft can become a functional room that will help you adapt your home to your needs. You can convert it and make an additional room. If its height is small and you lack it, consider installing a dormer to add space above your head and more natural light. Extensions on upper floors or in the attic may also require a permit. This depends on the local municipality and the location and size of the dormer window. A loft can become an additional bedroom, a playroom for children, or an office for those who work remotely.

Basement Conversion

If you have a basement in your house that you don’t use in any way, you actually have a lot of free extra space that you haven’t thought about before. If your basement is large and stretches across the entire building, you can easily turn it into a full-fledged small apartment with several rooms. To understand whether you will be able to bring the idea to life, you need to analyse many features. These include the condition of the walls and flooring, the possibility of heating, height, etc. If you have at least the minimum conditions for an extension, you can organise a home cinema, gym, or even a swimming pool. If your semi-detached house does not have a basement, this option can be difficult to realize. Building a basement can be very expensive or impossible due to the common wall with the neighbouring house. However, if there is a basement and it is suitable for repair, it is time to think about its reconstruction.

Garage Conversion

A garage is another way to increase your living space, especially if it is attached to the house. It will require modifications and possibly major repairs, as you will need to arrange an additional entrance, take care of heating, insulation, ventilation, and lighting. However, this is one of the cheapest options for an extension that allows you to get a spacious room for your needs. Most often, homeowners turn garages into home offices or rooms for hobbies and sports. Functional use of the garage can increase the value of the house and provide space for leisure activities.

Open-Plan Kitchen Extension

Semi detached kitchen extension is a very common option used by most homeowners who plan to enlarge their houses. It involves creating an open space that connects the kitchen with the dining room or living room. Installing panoramic windows or sliding doors to access the garden provides more space and light, but may require significant changes such as demolition of walls. However, this is a great opportunity to expand your home if you have long dreamed of a spacious kitchen where you could gather with your family after work or on holidays.

Garden Room or Orangery

A small extension to be used as an internal garden or greenhouse is available for construction in almost every house. This room can be transformed in a reading area or relax room to enjoy the views from your home. It adds elegance and value to the house and can provide better natural light and more access to fresh air. This idea is especially useful if you like to grow flowers but don’t have enough space in your home to do it. With an extension, you can turn your dream into reality and create a cosy corner for your hobby.

Home Office or Studio Extension

A home office can be one of the rear extension ideas for semi detached houses. However, the backyard is not the only solution. You can build an office or studio in the attic, garage, or even basement. If you work remotely or need a little space at home to work, adding an extension will be a good decision. You can design a room that leads directly to the garden and has large panoramic windows. Take care of good noise insulation, lighting, and thermal regulation to create a comfortable, easy-to-work-online space.

Key Considerations Before Planning an Extension

Any of the semi detached extension ideas that you plan to implement requires careful analysis, planning, and weighing of the pros and cons. Here are some of the main factors that you should pay attention to when deciding to update your home:
  • Expectations and purpose. Your goal will dictate the expansion design you choose. If you need an extra room, consider building it in the backyard. If you want to get several rooms at once, you should most likely design a double-storey structure.
  • Budget. If it is significantly limited, it often becomes a crucial element to take into account. Large and complex extensions will require more money than an attic renovation or garage conversion.
  • The time you have. If you are in a hurry, you should not plan a major construction project. A small extension of the area or reconstruction of existing rooms will suit you better.
  • The need for permits. If your local authority requires a permit, expect that it may involve collecting documents, waiting for the application to be reviewed, etc.
  • Obtaining consent from neighbours. If your project will not affect the daily lives of the owners of the adjacent property, you are unlikely to encounter any difficulties. However, since your house is semi-detached, you should talk about the topic with your neighbours.
  • Finding a reliable contractor. Most extensions are difficult to implement on your own. To cope with the procedure, you are better off seeking help.

Design Tips for a Seamless Extension

The extension should not only perform the functions assigned to it, but also fit into the overall structure and area of ​​​​the house. To get a renovation and some additional space that will be functional and in harmony with your building, take care of:
  • Integration of architectural styles. You do not necessarily have to design a room in the same style as the others. You can easily combine modern semi detached side extension ideas with a classic building, provided that they complement each other and create a pleasant appearance.
  • Increasing natural light. Install large windows or sliding doors, and add dormers. They will provide a better view of the house, both inside and out.
  • Improving energy efficiency. Your house will become larger, so your energy bills will increase. In order not to get excessive consumption but keep the house warm, consider installing energy-efficient windows or doors.
  • Analysing all the features of the building. A semi-detached house has its specifics. Don’t neglect them to get the best result.
  • Hiring a designer. If you have no experience, designing an extension can be challenging. You will spend much less time and effort if you hire a designer who will help you better organize the space and give practical advice.
Creating an extension can be laborious, so you should know about all the pitfalls and tricks, but entrusting the process to a third-party company. It guarantees compliance with standards and building requirements as well as the accuracy of the construction.

Choosing the Right Materials and Finishes

Choosing the type of extension is not the only task. You also have to determine the material and finish that you will use for it. Since they should harmonize with the rest of the building and rooms, the final choice will depend on the style of the house, your preferences, ideas, etc. The most popular materials are:
  • Wood. It is a classic building material that often fits well with others.
  • Glass. It provides more light and a better panorama.
  • Blocks. It is a cheap option that can be easily improved with plaster.
  • Brick. You can use it because it is universal, optimal in price, and easy to work with.
  • Stone. It is a massive and expensive option that should be chosen if your house has the appropriate style.
The choice of finish as well as building material is very large. Determine their list based on the initial data.

Conclusion
