Bumping out or bumping up?

Having the expertise of quality home renovation builders and designers means there’s a huge amount of possibility when it comes to modifying your house. For many timber-framed homes, house extensions are an option as well as raising and building underneath. Like anything with home renovations, there’s pros and cons for both options.

 

The cost could be significantly different

House extension costs can vary hugely depending on the plans, but if you’re looking at just a small addition to your home, an extension could be lower in cost than raising. Raising and building underneath means a new concrete slab; whereas for many extensions, a slab isn’t required. It all comes down to what you’re trying to achieve with your home renovation: if it’s simply adding a room or two, or opening up the space, raising the house would probably be a costlier option that isn’t even suitable for your needs.

 

You could sacrifice a blank slate

When raising a home, the new level underneath often has to mirror the upstairs layout: foundations and load-bearing walls need to be put in particular spots to support the upper level. By contrast however, with house extensions you could have the opportunity for a blank slate. Depending on the size of your lot and how it’s laid out, you might have more freedom with the configuration of your new space.

 

Speed is key!

Raising a house can be a lengthier process, simply because there’s often more prep work required before the build can commence. Not only does the house have to be raised, but it needs re-stumping; the land underneath will often need to be excavated and levelled; and finally, the new concrete slab will need to be poured and set. Obviously for many house extensions, the majority of those steps can be skipped: while some excavation and levelling may still be necessary, the biggest time-saving is the absence of a concrete slab – which can take up to four weeks to cure before building can even start!

 

Ultimately, whether you bump up or bump out will depend on what you’re trying to achieve with your renovation; the layout of your existing structure; and how much space you have to work with.
