A house extension is the process of adding a new room or set of rooms to your home. It might involve building on the side, rear, or top of your existing home structure, expanding the square footage and adding more space to your home. 

Home extensions range in size significantly.

If your home is no longer large enough for your family, you may consider moving as the logical next step. However, our house extensions in East London offer several benefits over moving and are a worthwhile choice for many homeowners. 

These are the benefits you gain with a home extension: 

  • Increasing living space: Whether you want to add one small room or an entire second story to your property, home extensions increase your living space and give your family more room to sprawl out. You’ll have the extra space you always dreamed of to use as an office, additional bedroom, hosting space, or whatever else you envision. 
  • Boosting property value: Home extensions can increase your property value once you place your home on the market. If you live in an area where all homes are a similar size, your house will be a desirable option for families looking for a larger space. 
  • Helping you avoid moving: Moving can be stressful and expensive, and your new home probably still won’t check all of your boxes. A house extension lets you avoid the hassle of moving while still enjoying a larger living space. 
  • Adding storage: Perhaps the reason your home feels so crammed is that you do not have adequate storage for all of your family’s belongings. A house extension can add storage space to help your home feel less cluttered and more organised. 
  • Letting you stay in your existing location: Many homeowners hesitate to move because they love the area they currently live in and know they won’t find another property in as desirable a location. House extensions in South London let you stay in an area you already feel comfortable in, with the neighbours you already know. 
  • Customising your home to your family’s needs: A home extension lets you choose the exact shape, size, and location of your additional living space. For example, perhaps you add a primary suite on the opposite side of the home from the kids’ bedrooms, or maybe you add an office space with a separate entrance on the side of your home. You can customise to your family’s needs and choose a layout that makes the most sense for your lifestyle.

Whatever benefits you’re seeking, our house extension builders in London can add a beautiful addition that flawlessly executes your vision. 

We have completed hundreds of projects for our London clients and have experience with several types of extensions, including the following:

Rear extensions: 

These additions extend into your garden area, making good use of space you might not currently utilise. Rear extensions are ideal for adding bathrooms and bedrooms or expanding kitchens and family rooms. 

Side return extensions:

For narrow Victorian homes, side return extensions can increase the width of the house and give more breathing room. 

Wrap-around extensions: 

If you are looking for a larger extension, we can combine a rear and side return to create an L-shaped addition. Clients often use this design to create an open floor plan and expand their living spaces. 

Double-storey extensions:

Detached and semi-detached homes can benefit from double-storey extensions that add ground and first-floor living space. For example, you can expand the family room on the ground floor and add a bedroom above it. 

Basement extensions: 

If you do not have much outdoor space to use for an extension, consider a basement extension. We can add a new below-ground floor to your home to use as a gym, extra bedroom, media room, or even simply a storage area.

Are you unsure which style would work best for your home? Maybe you have a broad idea for the extension but aren’t sure how to execute it. Our builders and designers will craft a design that works for your home’s layout and meets your goals.

Frequently Asked Questions

A house extension in London can vary in cost significantly depending on the type of addition you are looking for and a range of other factors. We will provide an in-depth quote during your initial consultation. We also remind you that house extensions often offer a high return on investment, which you should factor into the cost. 

Side return extensions are common in Southwest London due to the large number of Victorian homes in the area. However, we have added all types of house extensions in Southwest and West London.

Most homes in London are good candidates for house extensions as long as they have the space necessary to expand. If your home is on a small lot, we can discuss a basement extension or an attic conversion, either of which may provide you with the square footage you are looking for without needing to expand outward.
