Thank you all for your comments. It’s a little bit daunting putting something like this together. All that I’ve proven so far is that I’ve got too much disposable income.
The actual house is ~250 square meters which is about 2700 sq.ft. This does not include the garage / workshop or the indoor pool. The below shows the house on the site.
RE: the position of the tank, like everything in life, is a compromise between several competing requirements.
A key part of the brief to our architects was the ability to zone into ‘pig-sty’ versus ‘worthy of guests’ living areas. I am not proud to say that I am somewhat domestically challenged and live in a perpetual mess, a lot of which is paper work. The south entry is the entry for my family. The intention is to walk in through the study on the way to the kitchen, off-loading bags, journals and other paper work in the study on the way through, helping to contain the mess. Similarly, the lounge can remain a bit messy and can easily be zoned off. Guests will enter via the eastern entry.
The other significant limitation is in the detail of the passive solar design (USA folk need to consider in the southern hemisphere, the sun arcs in the northern sky. I live in a position that is not dissimilar to a southern hemisphere San Francisco). In order to achieve its level of efficiency, most of the northern wall is double glazed glass. The floor area of the kitchen, dining and living area will be exposed thermal mass (polished concrete or tile). In the winter, sun that is low in the sky will come in under eaves and heat the floor, to be re-released later. This combination will maintain the main living areas at around 17C (63F) without any heating. An important factor in maintaining winter comfort is the isolation of the colder southern wall from the living area… hence the sliding doors around the aquarium.
My only mild disappointment is that I would have loved to be able to do without most of the west wall of the lounge room. That would have allowed a 180 deg. view from the entry, the lounge and the living / dining area. I am, however, content with the design… bear in mind the cavity sliding door in that wall should be able to retract almost to the corner with the entry wall
RE: visibility from the study, I don’t spend extended time in the study, so it was not a priority. More important for me to be able to see it while cooking and dining.
Its a personal choice thing really. I would however widen the hall way between tank and lounge wall to 1200. When your walking that close to something so big its a bit intimidating. You wont notice 200 gone from the lounge room but it will make a big difference to the impact and admiration of the tank.
Adrianvh, your suggestion makes some sense... I will consider it.
I should mention that the internal equipment room will only contain surge tanks, 2 low RPM pumps (to keep them quiet) and 3 quarantine tanks as well as lighting equipment and air exchange. Most of the equipment (5 regular RPM pumps, skimmer, sump, refugium, crytic tank, 2 frag tanks, kalk stirrer, calcium reactor, RO gear, heat exchangers and water storage) will be housed in an external processing room in the garage / workshop area.
As for the tank, I take my inspiration from the usual suspects… Energy; Steve Weast, Sanjay, Machado deSousa and a fellow Geelong Reefer, gcapon.
Probably about 50% acropora; 20% other SPS; an Heteracta magnifica on its own bommie (if I am brave enough); a couple of Entacmaea quadricolor and the rest a mix of softies for movement (e.g. Cespitularia spp. Xenia spp. Etc). Would love a Tridachna gigas (just like Waikiki), but somewhat ironically, very difficult to source in Australia.
A large focus on space and perspective, rather than cramming in as much as I am able.
Hopefully a large skylight to provide ~50% of lighting needs. Fairly standard Berlin with DSB.
Damer, you have the right Diablo... just more people know Melbourne than Geelong.
