1930’s Queenslander - raise, re-stump, frame + clad lower level

Hi everyone, we’re in the initial planning stages of the project to raise our house. It’s a 1930’s porch and gable style Queenslander in Holland Park, with a decent front to back slope (approx 2000mm over the existing footprint) which is concreted underneath.

We are looking at various options and builders to work with to have the first 3 stages completed.

Stage 1 - raise, 1000-1500mm to bring the existing entry up to street level and create a 2700-3000mm lower level, potential slide to the right of 400-500mm (pending builders suggestion and council approval) new steel stumps, pool excavation, concrete slab (including driveway and path) new roof and guttering, plumbing and drainage for future works.

Stage 2 - Frame perimeter of lower level, include doors and windows, clad walls.

Stage 3 - minimal alterations to upstairs, new internal stairs, new external stairs x 2.

NOT to be completed;

Stage 4 - this would be the progressive fit out of the lower level

Landscaping
Painting
Kitchen
Bathrooms
No lining of walls or flooring

Downstairs would pretty much be a shell at the handover point. However, plans would include all services for plumbing and drainage, in order to have this completed in the initial stages.

There is a stormwater easement over the back fence (part of a newer development) so, hopeful that this already has an available tie-in for any stormwater/pool drainage requirements.

***Looking for any suggestions or help regarding the budgeting, also contractors to use for the work***

Current rough estimates are as follows;

Raise, excavate, re-stump, concreting, drainage, plumbing, framing, cladding, extension of roofline to cover the existing deck, internal and external stairs, rectification of enclosed front verandah (reinstate original facade) all the essentials for the house to look completed from the street and be suitable enough to live in while completing the lower level, and then progressively renovate the top level. Disconnections and reconnections of services etc included in this $120-$130k

New roof and guttering $20-25k

Pool - excavation and installation $30k - possible saving a small amount here with combining the excavation work.

I realise I’ve combined the stages a bit in the estimates above, but this is how we have been quoted so far. If anyone has a good breakdown of costs that they’re happy to share, that would be much appreciated.

Looking for anyone with local or relevant experience completing this type of renovation more recently, any suggestions on estimates or areas to consider for cost savings would be great!

We plan on creating an extensive spreadsheet of estimates, quotes and actual costs when we get started and will be sharing this down the track to help others

Thanks in advance

 

Thanks for that info where was your development? I’ll get in touch with Matt and see if he is interested in quoting for our project. Thanks again!

 

If your picture for your ID is your house, then it is similar to my own PPOR I did a few years ago, it was a lift-up, big extension, and total renovation inside (i.e. strip back and re-do) - it was a big job. Some things to be aware of from this experience:

1. If your property is pre-1946 it is likely to be TBC (Traditional Building Character) and will likely need a DA (Development Approval) before any alteration can be done. You should consult a Town Planner for advice, apart from Town Planning fees, a site survey would be required and plans for what the final result would be (you may also need a Building Designer or Architect). Even when lifted, you need the Surveyor to confirm the height and certify it. There's is planning and professional services that you may need. Always good to get some Builders to quote / give an appraisal and ask what's included. Please check.

2. Most older Queenslanders have asbestos sheeting in them, and hence you may need (or should) get an assessment on the asbestos contained and whether the works you anticipate are a hazard and require treatment. When I did my reno there was a lot of asbestos, especially downstairs underneath the house where the laundry was.

3. For the raising, need to also check if additional structural steel is required to add integrity to the house. As it is lifted-up the nature of the house changes. Check with the proposed house raising company, architect and/or structural engineer, or builder.

4. Whilst contemplating stages, it's best to get plans drawn up for final result and intermediate stages, whilst you think you don't want to change upstairs of the existing house, need to consider the stairs and general flow of the house and how it would work for you, not surprised if later on, you want some changes. Note that a new front stair case would be required. Even lifting up with the new pool - how does the existing house relate to the pool area?, are you going to have a bottom deck?, is it timber or concrete?, what type of access would you consider?, where would you put the laundry etc. Things change, hence consultation with a Building Designer or Architect or Builder might be good.

5. To reduce some initial cost, for downstairs, you could batten out around the perimeter of the house, and do the completion of downstairs later.

6. In terms of cost, think that your $120K - $130K could be a bit light, I think there will be other issues / costs that prop up and allow extra contingency to be safe. For example, professional services above, maybe electrical / plumbing to bring up to code, any asbestos issues, etc. Renovating Queenslanders is not cheap.

Any other queries, please PM me. Hope this helps.

 

Hi there,

thanks for taking the time to include so much information in your reply,

1. The house is the one in my profile photo what area was yours in? As ours is a 1930’s build and in the TBC, I have already spoken with council and a town planner regarding the requirements.

2. Yes, asbestos. We do think there will be a small amount, but I didn’t think about the laundry area. Thanks for highlighting this one.

3. We plan on engaging a reputable qualified builder, I am sure they will point us in the right direction with regards to steel. But would be good to know if there is a general rule of thumb when it comes to open plan areas and the need for steel?

4. we plan on completing the entire lower level floor plan, and building to accommodate this. As much as I’ve said we will not fit this out initially, we will engage contractors along the way to progressively finish it, once we have moved in and got the initial bill out of the way. So all wet areas etc will be mapped and thought out with the builder and Drafty/ Architect. Thanks for highlighting a few key points, I’m going to use this forum to create a checklist for when discussing with the builder.

5. We considered this, but want to be able to fit it out in our own time. So think it’s worthwhile to spend this money enclosing it now.

6. thanks for your input. I’ll pm you soon with a few more details and questions.

have a great weekend!

 

Some people i know have used the link below and cost wise they would be in the high range but they have been around a long time..
Also as long as that power-line does not cross into next doors foot print with the lift then you will not have to move the outside supply post will can bump up the budget a few percent ..good luck..

imho..

 

When you look at the power-pole for a start ,then bring the plumbing up too the new codes the same as the elec's which may may well have to be fully rewired new boards ect those three alone can add a very high %into the costs ..excellent area location ..imho..

 

Thanks for your reply. I’m not sure exactly what you mean about “footprint”. Is this the house footprint? Or their property boundary?

Thanks

 

Switchboard and wiring are all compliant, so no real concerns there
