Thinnest House

This  1m wide building was designed  by German architect Nils Holger Moormann as a garden house.

It includes living, dining and reading rooms all with open sides.

The exterior walls have cupboards for gardening implements,  tableware, and a barby.

The door even leads to an upstairs bedroom with a glass roof

You can see more photographs at Dornob.

I don’t know how you would go if there was a strong wind on the side though.

How Many Construction Inspections?

Well I do my own inspections, so for my houses they have been at least once week. . . . . but if you are paying $4-500 an inspection for a professional you might want to consider the options below!

Just remember the fewer professional inspections the more you should take an active interest yourself.

Option 1

Five Inspections based on the Standard Progress Payments

  1. Base – Best to inspect before the slab is concreted to check:- The slab is in the right location, plumbing is in the right place, and site is properly drained to avoid the ground becoming waterlogged.
  2. Frame – This is the main structural component of your house. It should be assembled properly and according to the engineering details. The slab can also be checked for problems.
  3. Lock Up – Time to ensure that the outer shell of the house is weatherproof and the brickwork is satisfactory. At this stage check  if pipe work and electrical cabling are in the right places. You may also be able to check if  the insulation is correctly installed.
  4. Fixing  Waterproof membranes in wet areas correctly installed.  Architraves, skirting, doors, baths, basins,  sinks, troughs, wall cabinets, cupboards, bench tops, shelves, properly fixed in correct locations.
  5. Practical Completion (PCI) – The last chance to get mistakes and omissions sorted before Handover.

Option 2

Three Inspections

To save money you could reduce the number of inspections to the following three.

  1. Base – As 1 above.
  2. Pre-Plaster – As the frame is still visible before the plasterboard is installed this becomes a combined Frame, and Lock Up  Inspection.
  3. Practical Completion (PCI) as 5 above. 

Option 3

Some people might only be prepared to pay for one inspection and go for the PCI.

My thoughts would be the Pre-Plaster Inspection would be the one to choose.

This is a chance to pick up any serious structural issues before they are covered up.

The PCI Inspection really is more about picking up finishing quality issues than structural issues.

Solar Power – No North Facing Roof

Conventional wisdom has been that you needed a North facing roof to mount your solar panels . . . . . . but it might be time to re-think!

Cost of Panels

In the early 1990 when people first really started looking at solar power for the home the cost of  pv panel alone was in the order of $7-8/watt and installation efficiency was very important.

Now with panels costing less than $1/watt, installed, adding a few extra panels isn’t as big an issue as it used to be.

Efficiency

The efficiency drop  off from moving away from a North facing roof is not as much as you might think.

For instance panels on a roof facing either East or West can still produce more than 80% of the power of a North facing panel. (see Solar Alignment for more information)

More Effective Spread Of Power

A few years ago we were paid for every watt we put into the grid, at more than it cost to buy a watt from the grid. This meant that systems that produced lots of power when we weren’t using that power (typically around noon) had real advantages.

For new systems you are now typically paid less for every watt you produce than a watt costs to buy. It therefore makes sense to be generating power when you need it across the whole day so you use as much of the solar power yourself.

A couple of options are:

  1. Split the panels evenly between say Westerly and Easterly facing it you are looking for an even spread of power across the day.
  2. Concentrate on westerly facing if your main power use is in the afternoon and evening.

A Few Final Points

  • Although this post has been mainly written for grid based systems there will be some benefits for more even power generation for stand alone systems, as it could reduce the battery discharge cycles,
  • In the past, to maximise efficiency, systems were built with mechanical trackers to follow the sun. With the current low cost of panels I don’t think trackers can be justified due to cost and increased complexity.

Quirky Rome Apartment 2

Earlier this week I posted about the quirky apartment we have rented in Rome.

Here are a couple more photographs.

The first shows the wall that separates the entrance hall from the Bathroom / Laundry.

The wall is a translucent material with a blue tinge on the external surface and a white surface on the bathroom side.

The lights are mounted inside the wall to illuminate both rooms.

I am sure you will agree that it gives quite an unusual effect.

Another interesting thing was the security.

This photo shows the locking mechanism on the steel lined door.

It looks more like the lock on a bank vault than a domestic dwelling.

Don’t think I have shown you all the quirks;  I have left some for any readers to check out if they decide to visit.

See the previous post on a Quirky Rome Apartment to find out more.

Quirky Rome Apartment

I am on holiday in Rome at the moment.

When I travel, rather than stop in a Hotel, I prefer to rent an apartment and feel a little bit more like a local.

The apartment I am renting here is more than a little bit quirky so thought I would share some of the design ideas over the next couple of posts.

The above photo shows the bed ‘cave’ . . . you go down 4 stairs to a ‘bed room’ which is only just bigger than the bed and has no windows; its easy to sleep late, with no curtains to let light in.

The next picture shows the stairs from the entrance door up to the living/dining area.

The individual stairs are cantilevered of the wall off the building with no balustrade, although there is an adjacent bulkhead.

Not as dangerous as this staircase (Safe Stair-Fail) but I don’t think it would meet the Building Code of Australia.

We are really enjoying staying here in very centrally located apartment at only 110 euros a night.

If you are planning to visit Rome and want to stay somewhere different you can find this apartment at www.airbnb.com

Teapot Chimney

I saw this whimsical chimney while I was out and about in Melbourne’s South East Suburbs the other day.

It was on a 1930 house with a few Art Deco features.

It certainly made me smile!

Sorry about the picture quality but it was take with a basic phone camera from a considerable distance on a dull day.

I have since found out the chimney was in fact a ‘Secret Sign’ as this house was a “Sly Grog Shop’ (where you could get a beer when pubs had to shut on a Saturday)

Onsite Stormwater Dention – Why

If you want to redevelop or subdivide an existing urban house block, you might find that a planning condition is that you will need to provide On-site Stormwater Detention (OSD).

You may also find it is a condition on individual blocks on smaller subdivisions.

Why Is Onsite Stormwater Detention Needed?

Before development of towns and cities a large proportion of the rain that fell in an area soaked into the ground or flowed slowly across the land to a creek or river. When areas started to be developed two things happened:

  • More and more of the land was built on, or paved, which meant rain was unable to soak into this ground.
  • Stormwater drains were built to carry the rainwater quickly away from the houses to be discharged into streams and creeks.

Initially while Australia had a small population this didn’t cause too many problems.

Since the mid 1950’s and the rapid growth in population more and more land has been built on.

The result has been more and more water has been discharged surface water drainage systems causing overloading of the piped systems and flooding of the rivers.

In order to try and reduce flooding Planning Authorities are attempting to reduce rainwater flows from developments to a flows similar to an undeveloped site.

OSD On Large Subdivisions

If you buy a block on a large subdivision it is unlikely that you will be asked to provide OSD on your Block.  This is because large developers  as a condition of the overall development have to provide Stormwater Detention Storage for the whole development.

The way they usually do this is by making much of the open space they also have to provide as Ponds, Lakes or Wetlands, which can fill up during periods of rain and then slowly empty. (Now you know why so many developments have a reference to Water in their name)

Other posts will explain more about how the Storage Volumes are Calculated and will look at various storage options.

Guide to Buying a Block has lots of info like this on what to look for before you buy land.

 

Types of Floor Joists

Build a single storey house on a slab and you don’t need joists . . . . but if you have a suspended floor, or you have a two storey house, your structure will need joists.

When I first started getting interested in houses the standard joist was a solid timber section, something you rarely see these days.

Modern alternatives are lighter, use less wood and can span greater distances than the solid joists.

With the wide range of joists used in house construction I thought I would show three common alternatives to traditional timber joists.

 

HY Joists

These composite joists are lighter and use far less timber than a solid joist for an equivalent span.

They comprise of a solid timber ‘flanges’ bonded to a ‘web’ of plywood.

They provide room for services like heating and cooling ducts as long as the services run parallel with the joists.

In this photo you can see the ‘end blocking’ which is used to ensure the joints don’t topple over.


Pryda Longreach Truss Joists

These trusses are assembled using standard timber sections for both the chords ( the top and bottom timbers) and the connecting webs.

Joins are with gang nail plates at each connection point.

This truss does give more flexibility with the direction that services can be run, than the HY Joists.


Posi Strut Truss Joists

Pryda Span trusses have metal diagonal webs to save weight and cost.

They are better for shallower trusses where there is more clearance room to accommodate services than a timber web product.

In some instances, some of the diagonal metal webs may be replaced by timber websdependant on load or geometry considerations.

Webs may be on both faces of the truss or just on alternate faces depending on the design loading.

Forever Home

I often hear people talking about ‘Our Forever Home’ . . . . . . . well this is a $2,000,000 Forever Home.

Some of the features include:

  • Located in extensive ‘Gated Community’.
  • Very quiet neighbours.
  • Marble lined walls.
  • Air Conditioning.
  • Lift to the ‘Basement’.

I can’t think of many people who would be keen to ‘Move In’ though!

It’s actually a crypt in Melbourne’s Springvale Cemetery.
