Mona Vale Townhouse Development - Update

Hi guys,

My apologies to those following my development for not posting again sooner but there hasn't been too much to update you on until recently. Before I post an update I thought I better give a very quick update for those new to this development.

Here's a link to a discussion on my initial site purchase back in September 2006.

And here's a link to the initial feasibility and design concepts.

Since then I have had enormous support from many Somersoft members and thought I better 'out' a few of them:

JoannaK for helping me extensively with the initial feasibility.
MIZBUF for offering the name of an excellent architect in my area.
Jacque for also offering the name of an excellent architect, and the one I ended up selecting for my job.
Peter 14.7 for helping me with initial design concepts and for ongoing design assistance.
Jindaroo for her initial design sketch which proved the core of my brief with the selected architect.

and so many others for their assistance and support that I've no doubt neglected to mention...

OK, time for an update then:

Architect Engaged and Initial Design Concept Finalised

I interviewed several architects and finally seleced GartnerTrovato for this job for the following reasons:

1. They have extensive experience with MUH designs in Pittwater.
2. They have extensive experience working for and with Pittwater Council and know the entire development control team at council personally.
3. They have won extensive awards for their designs and all of the work of theirs that I saw was excellent.
4. They were cost comparable with the other architects but to my mind were of a higher standard and their experience doing this sort of work would be critical in guiding me through the process as my first MUH development.

So far those assumptions have proven accurate and the Sean Gartner (principal) has been excellent in personally managing my job.

The design brief was for a very high quality finish and for three dwellings on the site. Due to setback limitations as well as the requirement from council that two of the three be "accessible design" for the elderly, we settled on a single two storey townhouse and two single storey large units serviced by a lift. The necessity of two carspaces each and single street access off Darley St meant that a basement was also necessary. So the following design concept is where we are at today.

These are cut-down photos as my flat bed scanner can only take an A4 sheet and each of these is on A3. So you can't see the full landscaping design for the ground floor unit and townhouse but can see enough to get the idea I think.

There are a couple of compromises, like the use of a turntable in the basement to allow for easy access and egress from the double garages. But each property does get a 6x6m DLUG with a large additional storage area. We have also ensured that the ground level is all on one level and that the overall design is pretty much on a sqaured grid system with one straight shared wall with the townhouse. All of these things save cost as the building process is much simplified. There's no complex concrete lays, and no 45 degree walls or split levels. Its basically a single excavation and flat concrete lay then a reinforced basement roof and a single "very big" building that is comprised of three separate dwellings.

My personal preference is for the ground level unit as its 145m2 internal space and large external landscaped areas. The internal space is very well laid out and the kitchen through dining and outside is all one nicely tied together area. The townhouse I think is the weakest internal floor layout currently. A downstairs bedroom and only one bathroom detract from it, as does the fact that it gets very little direct sunlight to the downstairs living area due to its orientation. (the North arrow points from bottom left to top right along Pittwater Rd). I've asked them to try and rework that design and try and incorporate a walk-in robe to the master bedroom and a separate ensuite if possible. Nonetheless, it still has an excellent outdoor area and private entry to Pittwater Rd directly (not shown, cropped off bottom left). The upstairs unit lacks outside living areas so has incorporated a large deck in the design. There is even the slight potential of views to Mona Vale beach from that deck but the elevation at Baranjoey Rd means this is unlikely. It is still a very livable area with some nice design concepts employed.

When we move to more detailed designs I'll be able to better describe the use of different materials and the clever roof line and landscaping. But it is a very high spec finish in a very good location close to a lot of amenities in Mona Vale.

Properties just two buildings further back along Pittwater Rd have been selling recently for $850K for two storey townhouses. I've checked with several agencies and they have confirmed a real lack of "accessible" single level living properties and pent up demand for these of a high standard. Some single level units like the two I am proposing have been selling for a similar price in Golf Avenue. So, in checking with agencies around potential gross realisation they believe $800K for each of the three is about right. The addition of a basement has added to my cost equation and my revised feasibility numbers now look like this:

Cost:

$700K site
$1M build
$30K professional fees
$70K development loan interest (capitalised)
$1.8M TOTAL

Gross Realisation:

3x$800K units
$2.4M TOTAL

Leaving a margin of $500K if I allow an additional $100K contingency. That's still above my 20% acceptable buffer and I'll get a better feel for the actual costs when I start engaging builders for quotes.

So at this stage she's still all systems go! The $1M build cost is still within our means due to our existing equity and the fact that I've got a cash buffer that can service the full loan interest over the build timeframe. I'm going to book interviews with some preliminary contacts I've already made at a few different lending institutions. Now that I've got concept diagrams and a more accurate cost I'm ready to talk turkey. I also firmed up those costs by contacting and meeting a few different quantity surveyors to be sure of what my build cost would be per m2 in this area and to my high level spec of finish. They agreed that $2K/m2 built is about right.

If there's one key piece of learning I'd like to share at this early stage it is that you can't do too much research when designing a development. I've met scores of people from quantity surveyors to REAs to architects to potential buyers (at similar open houses) and I've learnt so much about what it is that I need to do to get it right. To use an old army adage "time in recon is never wasted."

I'd welcome any and all feedback and will do my best to answer any questions people have at this stage. Of course, I'll keep posting as it progresses further. My next milestone is a meeting with council's senior planner, and at a cost of only $835 the architect says its money exceptionally well spent in getting his initial feedback on the concept and in smoothing the way for the actual DA approval process.

Wish me luck.

Cheers,
Michael.
 
wow, I admire you!! personally, I wouldn't take on such an expensive project for that profit margin.

Although it's not that risky. But the learning experience sounds great and please keep us up to date.
 
Hi Micheal

Looks good Micheal.

I can't believe it, 'a lift' wow, and also that turntable. How much are these going to cost both in the initial costs and the ongoing maintenace?

One thing I can't seem to locate is an external strair case from the first story down. I would think that fire reg would require one. Also with the basement parking will this need a sprinkler system?


That balcony for the 1st floor seems to take a fair chunk of internal floor space. Is there anyway that you could push it out further?

Cheers

Hi Andreas, I had the same concerns myself so asked the same question. Apparently the lift costs about $30-40K to install and the turntable another $10K or so. These are factored into the revised costings. And apparently the ongoing maintenance is negligable for both which surprised me a bit.

Well spotted on the staircase thing. The architect spotted the same oversight when presenting the plans to me. It dawned on him that he'd forgotten the external staircase to the first floor unit. He sketched it in on the plans we were scribbling on from the front door straight out and down, but it will require some rejigging of floor plans a bit. Not sure about sprinkler system in the basement but I wouldn't be surprised.

That balcony for the 1st floor seems to take a fair chunk of internal floor space. Is there anyway that you could push it out further?
I think we're limited on how much we can encroach on that side boundary to Darley St. Otherwise we would push it out further. Also, there's a minimum external living space per dwelling in the council DCPs so we need that space for the upstairs unit. The DCPs really do limit what you can do, and the setbacks were the biggest issue for us on this site.

Thanks for your insights! That's exactly the sort of assistance I'm looking for to make sure I haven't overlooked anything. I'll ask about fire sprinkler systems in the basement when I call him next.

Cheers,
Michael.
 
Hi Michael,

Well done. It's sounding like it's all coming together so far.

Just one question about the lift and turntable. If I was buying one of these properties the ongoing maintenance costs would be a concern (although maybe if I could afford a property in this price range it wouldn't worry me :D ). Who told you the ongoings costs are negligible? I wonder if it would be possible to find a complex that has ones that were installed 5 or 10 years ago and find out what condition they are in. It's probably only a minor point in the scheme of things though.

Thanks for posting all your plans.

Keep up the good work :D

John.
 
Michael, with the basement car parks it may also pay to ask the question
and from the layout and storage areas apart from the sprinklers systems
you may also need car park ducted/fan/ventilation system for smoke
in case of a fire in the lower storage areas, apart from $$$? the tender
drawings look ok, and i hope you complete the job for that price,
what sort of buffer do you have in place with the one mill build costs
700k land content you would have to run this very tight..
good luck willair..
 
Thanks for posting Michael. Very interesting to see what s involved in a development.

Is this classed as a small or medium development ?

May I ask what contingencies the $100k is for ? Is it interest rate rises, excavation blowouts like hitting hard rocks, time delays due to rain, time delays due to council, more expensive building materials if cheaper ones aren't available in a reasonable timeframe ?

Cheers
 
I would like to see a driveway section to determine what the gradients are. Has the architect decided on any levels yet? It does seem to be a short driveway to get down an entire storey. Maybe the units are slightly elevated so you won't need as much distance?

Hi Sharon,

Yep, that's it... The site falls away from Pittwater Rd so Darley St is already over a metre below Pittwater and maybe more. I've got the contour survey lying around if you want me to scan it and post it up? But the result is a slightly elevated Darley St side wall and less drop on the driveway to access the basement.

I was toying with sliding garage 01 up beside garage 02 and freeing garage 01 space for more access and thereby doing away with the turntable. I could still get storage for garages 01 and 02 by excavating to the building line above and partitioning it in two. Do you think that would work? I was going to suggest it to the architect when I see him next.

Thanks for posting.

Cheers,
Michael.

Hi Will,

I'm not sure if its classed small or medium, but I'd think small as its under the $1M build cap.

The contingency is just a bit of buffer I've mentally factored in. I aim to get my build cost below the $1M rough estimate of today but was illustrating that even at $1M and with a spare $100K buffer I can return a $500K margin. My intent now is to make that margin even bigger, but my revised feasibility has it at around that mark for now.

Cheers,
Michael.

That would appear to be a good idea, otherwise it will be a very tight turn into the whole garage area. The other consideration is supports, as the wall on garage 1 would be supporting the slab above.

The other possibility is to also place garage 3 in the same line so they are all in a line and make them a little longer by a metre or so for storage.

This should reduce the likelyhood of careless parking inconveniencing other residents.

Cheers
 
Have you thought of doing a duplex instead of 3 units/townhouse. I guess you may have already considered it but by doing that you could save on lifts, turntables and the excavation no? Not to mention you can get away with not strata titling them. Probably have about the same profit margin % wise too.

Thanks for reminding me! On my initial calculations it didn't stack up, but with the build cost at $1M for the three suddenly a duplex looks a lot better. If I can project duplex it for $400K or under then my total cost runs to around $1.2M and if they sell for about the same price of $800K each then my GR goes to $1.6M making for a $400K odd margin which is not too far removed from where I'm pitching for three.

Before I lock in the three, I think I'll talk to some REAs about sale price for duplex pidgeon pair and also some project builders about cost to build. Its worth doing this due dilligence again if for no other reason than to be sure the three approach is the most effective use of the site. Basements certainly do add to your cost, so too does the extra build cost for a non-project build.

Definately worth checking out again, thanks.

Cheers,
Michael.
 
I know what you mean when you say the 3 approach is a more effective use of the land, the golden rule of bringing the land up to it's maximum use of course. The duplex route does have a few advantages to though. Another selling point could also be the bigger yard you would have! :)

Good luck with it all regardless im following this with a great deal of interest!
 
Michael,
My 2c worth.

The basement will be an expensive part of the construction as it involves excavation and then a suspended slab over. At this early stage of estimating the construction cost put some effort into the basement. The 2 levels of construction above can be worked out on $/m2 like you have done but add extra for anything out of the ordinary such as the lift, turntable, special stormwater treatment etc. BTW, API magazine Nov 2006 had an article on parking solutions including turntables.

Regarding meeting with Council you may want to query, if during the DA process that Council would be willing to issue you with a draft set of DA conditions. Gives you an opportunity to discuss and tricky conditions prior to Council issuing the final ones. Once you have the DA conditions you are either stuck with them, or it will take some time to go through the process of having anything amended.

Regards
Alistair

Hi guys,

I've looked into this in a bit more detail now. The number support a duplex approach as I've confirmed an $800K- $850K selling price for each, which incidentally is much the same price each of my three units should fetch with their higher spec finish. And at a $400K build price and no architect fees it looks more like $1.2M in and $1.7M out with a $500K margin. The only problem is that I can't find a project duplex design that will fit my wierd site shape.

I've looked at many websites and this one here at Masterton gives you an idea of the sort of layouts available. I've tried every single one of these and none of them come close to fitting my site with its setback requirements.

So unfortunately, the site is dictating that a custom design for the tricky site is the only way forward.

I've spoken to my architect again and he agreed that we should engage a few builders early in the process with a view to keeping costs as low as possible. They might help tweak the pre-DA design to eliminate cost adding aspects without impacting on the quality of the end product. I've set a revised cap on build costs of $900K that we need to work to. The architect is aware of this and already has a few options available to squeeze costs to this level in total.

So its off to council on Wednesday for my pre-DA meeting. I'll keep you all informed on how I get on and will post updated drawings and estimates as I go along. You've seen this process from the absolute beginning and should be able to track it through to the end with me. Keep your fingers crossed that I can deliver this project within budget and bring home an acceptable margin. I'm quietly confident that there's only upside on my current estimates that I published recently. ;)

Cheers,
Michael.
 
Michael,

I wouldn't bother too much with the project builders, they dont specialise in the type of higher class finish i assume your after. Not to mention as you've discovered the designs Masterton have for instance don't suit your block.

If you still wan't to go the project home route you may actually be better off checking out their stand alone houses and seeing if you can "Frankenstein" so to speak 2 smaller houses together along a common wall without windows rather than just go for a duplex. Might be worth looking into that.
 
I wouldnt be surprised if people would pay more for only two on a block. Sometimes people have a pet so like a bit more land, sometimes they have a "toy" extra car and need space for 3 cars, and I'm sure they would pay more not to have the hassle of a lift and turntable. You may make more out of two seperate houses on the block instead of 3 crammed in. Also, I'm sure Council will require a 100 year storm pump system in the basement garages

Update - Plans submitted to Council

Hi everyone,

Well its finally time to post an exciting update with regards to my Mona Vale development. We finally submitted a complete set of plans into council today for DA approval! Woohoo!!

These include:

  • Site layout (showing coverage calcs),
  • Floor Plans,
  • Cross Sections,
  • Shadow Diagrams,
  • Landscaping Plan,
  • Arborists Report,
  • Geotechnical Report,
  • Accessibility Report (2 of the 3 must meet accessibility criteria),
  • Traffic Flow Report (impact on road use and site access),
  • Statement of Effects (Nathers and BASIX),
  • and probably a few other bits I forgot to mention...
We are really happy with the archiect we selected and the service they provided. They came in on budget and their estimates for other supporting reports was pretty accurate. If anything it came in slightly less than anticipated as we skipped one or two. The quality of their work is exceptional and their knowledge of council requirements made the whole process completely painless. They are definately part of my future "team" that I see this whole development as a great opportunity to identify and lock in.

We have gone with the original design of three dwellings, made up of one two-storey townhouse and two single-storey (accessible) units. The basement has parking for 7 cars, which is a DLUG for each dwelling and a single visitor carspace left over.

It meets 99.9% of the DCP requirements and the preliminary meeting with Council's senior planner gave it the thumbs up. Now we just sit back and await approval (hopefully). We missed out on little things like forgetting to put a roof over the letterboxes which is a requirement under clause 1.9 of the accessibility criteria. Nothing that would cause us any real hassle to rectify if council insist on its adherance.

I'd load all the plans and stuff for all to see except the files are pretty big. Hopefully the attached landscape plan (which has been revised down from this somewhat) will suffice to give the idea anyway.

Wish me luck! Happy days!!

Cheers,
Michael.

PS The one labelled Town House 1 is actually the footprint for the two units.
