Foundation

And no, I'm not talking about the sci-fi series.

We started foundation work on the site last week. The first part to be completed was the north east rain water sump so that we shored up our neighbour's walls.

I am amazed everyday at the amount of skill and precession that is required to build something. I am also sickened that these people, who actually have real skills, get paid less than HR executives and call-center automatons. Also, things haven't changed that much in terms of tools... Plumb Lines for verticals and a pipe filled with water as a leveller.

That was completed last week. Just in time for the weekend of incessant rain.

This is all good news. The sump works, clearly. And we have extra water that we are now using in the foundations.

The pace is picking up on the site, and there are a lot more people doing various things: mixing cement, laying the foundations, shifting materials, measuring, digging. It's quite fascinating to sit and watch. You get sucked into it sometimes. Until you are told to move by someone carrying a heavy load of mixed cement.

This is what the foundations are looking like right now. If you're wondering why the lines aren't straight it's because the house is full of odd and interesting angles. Which makes the measuring and building even tougher.

This is what a foundation looks like. They dig really deep and pack it up. There's going to be another 3 feet or so above this before you hit "plinth level." That's the level where you have the slab on which your place your floor. The stacked cement bricks just above the trench end at floor level. The plot itself slopes down about 4 feet, from east to west. We've taken a decision to keep the floor level one foot above road level. This means that the house is going to be quite high and we're going to have to fill in the garden on the west side and build a retaining wall.

The little red mark is where the floor is going to be. This is on the north east side of the plot, marked against the neighbour's wall. The man on the left is Ravi, the site engineer.

This is what a cross section of one of the thicker walls looks like. After this, they fill it with irregular rocks and cement. We had to buy the rectangular rocks. But we will be filling it with the rocks that we have been quarrying to dig out the sump.

And that's a lot of rocks right now. There was some kind of sorting going on when I landed up there.

Another major component is sand. Which comes in by the lorry load.

This is my favourite picture of the site so far...

So far we haven't been involved much in anything. It's all very standard and our contractor and architect are talking to each other on a regular basis. Things are moving along at a quick pace without my wife and I having to make too many decisions. I suspect all that wil change once the foundation work is done.

Thoughts on working with an architect

We may have done this completely the wrong way, but these are my thoughts on the matter.

One thing that you want to do is spend as much time as you can on this part of the process. You want a "perfect" plan before you start building a house. The more changes you make while building, the longer it will take and the more the cost overruns. Don't rush the discussions or the design.

Step 1: Requirements
Before you start any discussions with an architect, even before you choose an architect, make sure you've listed all your requirements. You don't hire an architect who specializes in modern lines and then realize that you want something traditional.

Here were our requirements, in no particular order:

  • 1. Traditional sensibilities: We both like red oxide flooring, open verandahs, courtyards and tile roofs. Neither of us likes the "modern" look that so many houses in Bangalore seem to have these days. We're not saying that it has to be uber traditional, but we like the sensibilities.
  • 2. Courtyards, verandahs and openness: We wanted an open space where there wasn't a defining line between outside and inside. The indoors should be open and they should flow into the outdoor spaces.
  • 3. A large kitchen.
  • 4. General guiding statement: No such thing as too much utility space.
  • 5. An office space that is accessible from outside so that visitors would not have to trudge through the house.
  • 6. A large garden.
  • 7. The ground floor on one level, with a large bedroom there. All of which should be wheelchair friendly.
  • 8. A rehearsal space. Well, a flexible open space where we could have rehearsals, jam sessions, or a place where I could play around with my manly tool kit or papier mache dolls. With an easily accessible toilet.
  • 9. A sustainable house: Rain water harvesting and storage. Water recycling. Wired so that when solar technology and batteries becomes cheaper and safer in the next few years, we'll be able to just plug them in.
  • 10. No marble or any other high maintenance materials.
  • 11. We don't care about vastu .
Some of these are quite vague and some of these were quite specific. They're all important. We didn't compromise on the spirit of any of these. Don't be afraid to add things or modify specifics as long as the spirit is there.

You'll notice that, except for bedroom on the ground floor, we haven't really talked about layout. This is the job of the architect. Before we started, I had the idea of an internal courtyard that you see in really traditional houses.

Mistake # 1: Don't try and be too specific about layout. That's what the architect is for. State your requirements and let them put it into a plan.

Our architect pointed out very early on that this isn't really feasible in a plot like ours because it takes up too much space. However, when we get our own farm (to sustain us through the coming apocalypse), we're going to have a lovely internal courtyard and be as traditional about it as we want.

Step 2: Discussion and understanding

Here our architect sat us down and had long involved chats with us about what we wanted and why. Questions about what we like to do in our spare time, what our daily routine was like… Some of the questions were tough because we hadn't gotten married yet and we hadn't moved in together!

He also visited the site and got a feel for the neighbourhood so that the house design would fit in with the surroundings.

All this is vitally important because your architect is designing the building that you will be living in for, hopefully, the rest of your life. This is time well spent.

Step 3: The first plans

The first plans will be bad. Just like the first draft of a novel. This is a fact. Your architect is still trying to figure you out. They're trying to figure out your requirements. You're still trying to figure out your requirements.

It's a start of a long journey, keep that in mind.

Mistake # 2: We (my wife and I) tried to fix the problems with the layout. What we should have been doing is identifying all the problems and / or concerns and asking our architect to fix it.

We moved rooms to odd places and ended up with a plan where you have to walk through a laundry room to get to one of the bedrooms. This didn't solve any problem and made many more problems. And that was only one thing we did.

Instead trying to move things around, ask yourself "what is wrong with this? Why do I feel that this is wrong?"

You'll get an interesting answer like: The utility spaces are not large enough and seems to be woven into the living areas. Once you give this feedback to an architect, they can work with it and actually come up with a better plan.

Step 4: Changes and refinement

At some point, we felt that we were hitting a wall with our architect. So we sent him the following email.

When we first met you, you were full of really far out ideas. I remember, at our first meeting, you pulled out a model of a cooling tower. On our second meeting, we had a long conversation about a two story kitchen and solar cooking! These ideas were, quite frankly, scary.
But that's why we hired you! We wanted an architect who would challenge our notions and constantly push us to try new things. We want to be at meetings where you will come up with far-out ideas and we will pull them back or trim them down.
The design at this point doesn't really push the envelope. It's certainly different and interesting, but we would like to see more of that first person we met. We want to see interesting and weird environmentally sustainable ideas... If you want a cooling tower, put it in and sell it to us! Please don't hold back, have fun!
We'll play the role of editors, and we'll trim it down or cut it out if we're too uncomfortable with it.
That made things much better. And we had many long fruitful discussions and arguments after that. Just like running a business, you don't want to surround yourself with Yes Men. We won some arguments, they won some arguments. In the end, the house has evolved much better.

After this, it's a lot of sitting around, picking at things, moving walls slightly… lots of tiny changes.

Mistake #3: We asked our families for their opinions.

Two head are better than one, but too many cooks spoil the broth (and don't count your chickens when they are in one basket). They had too many ideas, often conflicting with what you want and with each other. Choose one or two trust worthy people who have run households. Their feedback is very good.

Also, they will tend to commit mistake #2. Listen to what they say and try and figure out why they feel that way. Communicate the "why" to the architect.

That's about all I have to say. It's a long process. We've been at it for more than a year. But it's a year well spent.Now that we've started building. We don't have to worry about making changes to the plans.

Next up: How our plans evolved, and how the construction is going.

Thoughts on selecting an architect


I was discussing this blog with a friend and we started talking about how we chose our architect. Just google “How to choose an architect” and you will get pretty much the same list of things to do. This is about our journey in choosing our architect. It reflects our tastes and working style.

1. Why get an architect

You know what a room should look like. You know what a house should have. Don’t put the doors too close to each other. Try and place the toilets close to each other to make piping easier. That’s about it, right? Why get an architect.

You know what a novel looks like. You know the basic rules of grammar. Don’t make the hero unsympathetic. Try and structure the overall story from the start. That’s about it, right? Why aren’t you JK Rowling?

2. Payment differences

One thing that most websites don’t tell you is the difference in payment and approaches. Here are three comparisons we received from three different firms.

        A        B      C
Fee percentage on total building cost        10%     7.50%      10%
Conceptual Design Stage 15% 10% 10%
Preliminary stage 15% 20% 15%
Working Drawing Stage 15% 50% 25%
Construction Stage 50% 15% 15%
Supervision stage 0% 0% 35%
Last Stage 5% 5% 0%


So, if your house is going to cost 50,00,000...

  A       B         C
Conceptual Design Stage 75000 37500 50000
Preliminary stage 75000 75000 75000
Working Drawing Stage 75000      187500 125000
Construction Stage 250000 56250 75000
Supervision stage 0 0       175000
Last Stage 25000 18750 0
Total 500000 375000 500000


Firms A and C are pretty much the same. Firm B is where the big difference is. They’re charging less overall, but they are saying that once they hand over the technical drawings they’re not going to be involved. This means that through the actual construction, they’re not going to do jack. They won’t help with changes to the plans. They won’t discuss issues with the contractor. They won’t guide the contractor on the minutiae of drawings. They won’t explain what is where.

The design process for a house does not end when construction starts, even if you aren’t making any changes to your plans. You need to decide where piping is going, wiring, what kind of toilets you want. There will always be some change as the house progresses. It could be something as simple as the way doors open, or moving a window from here to there.

A plan is only that, a plan. It’s like the script for a play. There is a lot of work to be done, choices to be made and possible a couple of edits before you have an end product.

Make sure you get an architect who will be available and will visit the site regularly. Their knowledge of the construction process is immensely valuable.

Incidentally, we chose firm A.

3. What to look for

We sat down and listed all the things we wanted from a house. 

We then listed a bunch of architects in town and started the interviews and portfolio viewing. Don’t skip the interview part! You cannot learn what you need from websites and online portfolios. They’ll take great pictures of fancy staircases and not talk about where the washing machine is going to go.

We looked at their portfolios and asked them why they had made certain decisions. This was really useful. We asked an architect why he put a little turn in a wall, changing the room from a rectangle to something resembling a boomerang. He said something like “We wanted to challenge the monotony of the space.”

All this sounds lovely, but honestly, it’s not useful when you are planning furniture and trying to hang paintings.

Looking at the portfolios with the architects you can very quickly see what their standard tricks are and what their design aesthetics are. You know they like to work with exposed concrete, or like blocky houses. You also get an idea of what kind of experience they’ve had. We spoke to one architect who had only done interiors and insisted there was no difference when it came to building a house. The only thing they had built as a small bedroom extension to a pre-existing house.

Most of the architects we met were screened out from the moment we started talking to them. They just didn’t gel with what we wanted.

Once we had shortlisted a couple of architects we made physical inspections of actual houses they had built already. Again, asking questions about their decisions gave more information than the actual house.

We chose our architect because he answered questions with practical answers like “We put the wall there because we needed some privacy in the kitchen” or, my favourtie, “that was a mistake, I wouldn’t do it that way again.”

Don’t go with your first gut instincts. Our architect didn’t make the best first impression, but we’re really happy with the choice we’ve made.

Those are my thoughts on choosing an architect. Sometime later I’ll talk about the challenges of working with one.

Drilling and Digging

I'm now the proud owner of 200 bags of cement. Not a lot, I know. But I try.

These are the guys who were hired to drill away at the hard rock. I had a small chat with them while they were on a break. The hard and soft rock are all mixed together in this vein. Make's it difficult to take out quickly. They were very confused as to why we needed such a big sump. I explained to them it was for rainwater storage.

This is what has been quarried so far. We'll be using whatever we can in the foundation. But all the soft rock is useless. That's going to have to be removed from the site.

We've started digging in the north west corner for the sewage treatment system. There's more hard rock there, so the guys with the powered tools will take over for that section.

This is one of the compressed air drills they brought.

They're also using sledge hammers, depending on the type of rock.

We've finished digging the sump in the north east corner. This is the baby pit, where we will be putting the dead babies water pump. This is right next to my neighbour's wall. He's been nervous about this dig, understandable. We'll be cementing this by the end of the week.

Up next, we have to cement the sumps and start off on the foundation work.

Pumps and Sumps

Back in May of 2010, we decided that it was time to drill a bore well on the plot. We hired a bore well chap who showed up with another chap who had coconuts and some copper wire thingies. He walked around the plot, dropped a coconut in two places, pointed the copper at them and told us where to dig.

The bore well chap we hired turned out to be a giant flake who kept postponing the work. So we hired another chap. By this time, it was about the third week of June. We started drilling, and I developed a 104 fever that day. They next day I was in hospital with 106. Yay. Anyhoo, we drilled down to 890 feet and got half an inch of water at 270 feet. I'm not sure what the 1/2 inch measures, I think it is somehow a measure of how quickly the column will fill up again. I've been told that it is enough water to run a house on.

On Saturday, the 2nd of April, 2011, we installed the pump. We went with a 3 HP 40 stage pump, 800 feet down. This means that, when full, we will have a column of water 530 feet high and 6 inches in diameter. This is about 2,900 litres of water.

The installation was interesting. They first tied one end of the 800 foot piping to an auto who drove up the road and let it uncoil.

Then they attached this end to the pump (the long metalic thing)...

And dropped it down the well. That reminds me, I need a schedule a prostrate exam...

The weight of the pump basically dragged the piping down. They had to just control the descent. Every once in a while they'd stop and tape the electric cable to the pipe.

And we got water! Yay. We weren't entirely sure if there would be water because of the abuse the water table in Bangalore has suffered. The next step is putting in a timer and sensor to make sure the pump doesn't run when the column has been drained...

This is what the site looked like on that day.

The water situation in Bangalore is precarious and is only going to get worse. So we are going to set up sumps for storing rain water as well as a decentralized wastewater treatment system (DEWATS) for processing all our waste which will be fed to the garden.

The site is pretty rocky, and we've discovered three veins of rock running through it under the surface. Luckily, one is a soft rock that crumbles quite easily.
Here's Ravi, he's the site engineer. This is going to be under the verandah and we're hoping to get about 27 KL of storage here. We're going to dig deeper here as well. To the right of the picture, you can see the soft rock that's being dug up. Just above his head is the hard granite. We're going to bring in some compressor tools and dig up some of that so we can expand the sump to below the driveway (top right of the picture.)

We're also going to put another sump in the north east corner under the utility area. That pile near the white wall is going to go away and the hole will become deeper.

This is our architect documenting the site with his own camera.

Once the sumps have been excavated, the next step is starting the foundation work. At which point we will have to say goodbye to one of the trees thats on the site. It's on the edge of the foundation and will be removed in a week or so. You can see that half its root structure has already been chopped off. Goodbye tree.
