Others will be along with better plan advice. I think you may be in luck. The area you want to convert is above the garage so you have more freedom to run the plumbing across the garage ceiling or walls. Aesthetics don’t matter so much in the garage.

Have you done an asbestos assessment, just mentioning as it can be surprise expense if you don't think of it at the start.

@macyjean I'll be getting a building and pest report.

This should cover me, right?

I'm a first home buyer so still a bit naïve about all this

@bigreader, Any idea how expensive these reno's are?

No a building and pest report doesn’t automatically cover asbestos. You need to find an inspector that can do it as well as pest and building or commission a separate report. It’s impossible to suggest a price range because you haven’t decided the scope of works you want to do and where you are located. Without a site inspection of where the services namely plumbing are, we’d only be guessing. Are you planning on doing any of the work yourself? Paying someone to paint a full interior house can be $20k or doing itself can be $2500 of materials. Flooring can be $60/sqm DIY or $150/sqm laid depending on what you select.

Cost is a bit like a piece of string. This is not a new house, so you need to allow contingency. Ones you start opening up walls, you will see what electrical and plumbing issues, whether you have mould, rot or asbestos. Be prepared to do plans, get builders to quote and then look at scaling back. Remember to allow contingency for this hidden extras, which can also include ac and heating. Planning a staged reno is often the way to go.

I assume you were looking for master suite upstairs in family/bed 4? An alternative may be to reconfigure upstairs splitting the large room with perhaps a metre from master into 2 bedrooms and making master suite out of bed 2 and the rest of current master. This allows the en-suite to be placed next to bathroom, where plumbing is more accessible. All rooms then get access to a balcony.
Costs, we’ll master with en-suite 30-50k. The rest depends on what you want to do and quality of fittings, Kitchen looks like it needs a new splashback.

We see this many times unfortunately, many times customers straight away think of the renovation costs like the strip out and prep has already been complete. My advise is you need to think how to strip it out carefully to save on reno costs. For example, many times when tiles and vinyl coverings are removed the floors do not get sanded down leading to uneven finish and water issues. Second example when striping out cabinets without conducting an asbestos assessment only to find out there is exposed asbestos on your walls can blow out budgets. The list can go on and on...(floor studs, termites, concrete cracks, warped timber making tiling a nightmare). During the strip out, these discussions are important as its the prep stage of your reno.

We always have planning discussions with our customers to pass on the savings...so look at savings then costs as they are directly related when renovating an older home.

All the best with your reno mate :)

@R M I typically use $1000 per sm for an internal reno and $2000 to $2200 for a proposed new addition. Hope this helps

Hello RH, I would think this could be achieved rather easily with not a huge cost. Pop a wall 1400 across the far end with door near the windows.. as long as the windows allow that space: shower across the end by stairs, loo and vanity ahead of the door. Bed head backing stairs/landing wall. Looks like the space behind the door into the room off the landing would be ideal for a long run of robe: not a walk in but very easy to add and plenty of space in bedroom (about 4.7 ish wide) and room for a dance! Cheers Margot

PS there would be far more complicated (read: expensive) options but this would suit the home too. As to modernizing: swap the splash back in kitchen, paint the arch bricks, maybe change the balustrade from the pillars (which may not be legal now) Change the beer bottle glass beside the front entry and enjoy! OH also I would look at using some of the under stair space to make a separate pwd room WITH the shower if possible... it will be possible.... and separate laundry. If the laundry ext door is centered in the room then you may have space for a folding, sorting, bench or more storage cupboards too....... Cheers MK

glad that you are going with the idea to get the asbestos report and before you start anything get a few local builders to quote you on the Basic re routing of plumbing, electrical and stud wall costs so you have an approx idea of how much it will cost you before you begin. the master bedroom reno thats how i did a full house reno on my house so i could save up and do up 1-2 rooms at a time. good luck with the reno’s.
