Top House Extensions related questions

That will depend on the scale and scope of your house extension, how quickly your Tasker and builders work; this can take at least 3 to 4 months at the very least. Other unpredictable factors like the weather can also affect your timetable, so consider that as well. You can consult your Tasker to estimate how much time your house extension will take to complete. 

Sure, but only if the house extension you want is not too complicated. Don’t forget you must also have the requisite skills, experience and equipment to ensure your build is up to code and has all the needed permissions from your local council. But if your house extensions are more complex and timing is essential, then you’d best hire an experienced Tasker to handle all facets of the job. 

Yes. In most states, you can only extend up to four metres from the rear wall of a single-storey detached house. Every other type of house can only extend up to three metres from the rear wall. In terms of height, your house extension can only be up to four metres. Note that these standards may vary, so check with your local council to design a house extension that complies with your specific state’s building codes and regulations. 

Yes, they do, but knowing the exact figure or percentage isn’t a one-size-fits-all affair. The amount or percentage value added by your home extension depends on its features, design and what buyers in your particular housing market want in a house. If you doubt whether to build an extension to increase your home’s value, you can consult an expert

A good strategy is to make the design as straightforward as possible. A pitched roof can cost more than a flat one, so consider that for your roof design if it’s permissible. You can also keep costs to a minimum if your house extension only has additional living space like a lounge or bedroom, without a kitchen or bathroom of its own. Consider using cheaper permitted materials and avoid double-brick or brick veneer frames for the walls. 

You can use materials that are in the original house. Most local councils insist on extensions having the same look as the original house and your neighbouring homes, but this may vary. If you want to use materials that are different from your original home and add contrast to your home extension design, check first if this is allowed by your state’s and local council’s rules.

What do house extensions services include?

Your house extension service includes all the tasks and activities necessary to add more living space to your home. Whether it’s to add square footage, increase your home’s value or both, house extension specialists can help with each stage of the project. This service typically consists of making the house extension design and house extension plans, managing the project, and executing the design. 

Home extension: Planning

Your home extensions Tasker can make a design and house extension plan if you don’t already have these. They can create a design and an appropriate plan that complies with your state’s safety rules and building codes and takes your needs into account - all while staying within your budget. 

If there’s enough time, some Taskers may present more than one design for you to approve. If you don’t have the permits ready before starting the project, some Taskers can get the necessary permits upon request.  

Getting materials & hiring labour

Once your design and plans are approved, your Tasker can proceed to hire the right specialists to do the build. Depending on your home extension design, they may hire specialists to take apart some structures like doors, windows or walls to accommodate the new extension before construction. 

As for the materials, your Tasker can buy all the needed tools, materials and equipment for your home extension. Should there be any excess materials after the project is done, they can turn these over to you. 

Implementing the design

Your Tasker can be on-site and make sure that all the steps in making your home extension go according to plan and the work stay on schedule. They can supervise any necessary demolition work before construction, but you may have to hire a separate service to remove debris from the site. They can ensure that any new foundations or reinforcement to existing foundations are done right and don’t block drains or damage existing plumbing, power or gas lines. 

Should your house extension need new wiring, plumbing or heating and cooling features installed, your Tasker can hire the necessary specialist for these jobs. They can oversee the work and check that these are compliant with safety rules, building codes, industry best practices and follow your approved design. 

Final inspection

As your home extension project nears completion, your Tasker can make a thorough inspection of the work. They can ensure that the build is of high quality and check for any flaws. Should your Tasker find any errors, they can have these redone until you are both satisfied.  

Once the build is complete, some Taskers can have the interiors of your new home extension painted upon request - although you might want to hire a separate service if larger areas need painting
