What are Home Extensions?

Many homeowners find themselves in this scenario: your family is growing, but renting a new home doesn’t cut it. You also can’t afford to buy a bigger house, or it doesn’t make financial sense to take on a new mortgage just for one extra room.

Home extensions are the perfect solution. You can build an extension on the roof, house, or basement. The extra space can be anything—a bathroom, kitchen, play area, home office, you name it.

Here’s what you need to know about home extensions today.

Top 4 Benefits of Home Extensions

Are house extensions worth it? Absolutely. A house extension offers the following benefits:

  • 1. No House Hunting Necessary

House extensions are a great alternative to relocation, which is a stressful process even at the best times. Instead of looking for a new house, packing, and moving, add the space you need to your current home. A house extension also saves you the hassle of finding new schools and amenities so you won’t disrupt your family and work life.

  • 2. Custom-Built to Your Style

House extensions are functional additions to your home, but they’re also an opportunity to make a design statement. You could opt to design your extension to match seamlessly with your home’s design or add a stunning modern extension to combine old and new. Work with an experienced architect to breathe life into your house extension design.

  • 3. Increase Your Home’s Value

A home extension can increase your home’s sale price only if done right. It’s best to leave the home extension project to a professional. If you take the DIY route, your extension may be full of potential problems that need costly repairs and turn off buyers.

  • 4. Plenty of Extension Options

There are numerous house extensions, such as single and multi-story extensions, semi-detached extensions, garages, lofts, basements, kitchens, and bathroom extensions. Think of the possibilities of having additional living space without moving house, but note that the extension direction matters.

  • Extend upwards to maintain your outdoor square footage, add a loft without significant construction work, and open your home to amazing upper-story views. However, add room for stairs in your design since they’ll take up some interior space.
  • Extend outwards for more design freedom, including open-plan spaces and impressive exteriors. However, extending onto your outdoor or garden space requires more construction work and a bigger budget.


Note: Since house extension are major construction projects, there are a few downsides you should know:

  • Moving out of your home is best to allow for construction work. But if you can’t or won’t manage to rent a place, inform your contractor in advance temporarily. A professional contractor will do their best to make sure you’re comfortable throughout the project.
  • Inform your neighbors about your house extension project. If you do move out for the project, they’ll still be around to hear the construction noise.
  • Check your local building codes to see if there are any regulations regarding proximity. There may be legal ramifications if your house extension is too close to your neighbors.

How to Determine House Extension Costs

House extensions are exciting but costly projects, so you should know how much they will cost beforehand. Depending on how you’ll use the extra space, several factors determine house extension costs.

For example, a bathroom extension costs more than a bedroom or garage because of plumbing, fixtures, and finishings. Other factors include:

  • Extension Size

A small house extension costs less in terms of materials and labor.

  • Accessibility

The construction team needs room for their equipment and on-site materials. It costs more if you need storage and transport from a separate location.

  • Hiring an architect

An experienced architect on your team will design your extension, give you accurate building quotations, and streamline your project–all at a fee, of course. Architects may charge a percentage of the house extension budget or a flat rate.

  • High-quality contractor

A skilled contractor brings experience, quality materials, and a service guarantee. If you skimp on your contractor budget, you may end up with high repair costs in the future.

  • Foundation

If you’re extending outward, you may need to reroute the plumbing, remove tree roots, dismantle patios, and so on. If extending upward, you’ll need inspections to ascertain your house’s structural integrity.

  • Finishings and features

Lighting, flooring, roofing, painting, doors, windows, HVAC, interior décor–all these affect your house extension budget.

  • Insurance adjustment

Any addition to your home means a higher premium, but you’ll also need coverage for the construction work before you start the project.
