Think Reverse

Since that building is more window than brick and the fact that all the windows are rectangular inline, I would consider constructing it backwards from the way you are thinking. Use strips to form the horizontal and vertical brick areas. Then there are no windows to cut out. They form magically.

Windows or no windows, a Dremel tool is incredibly useful.

Dremel

Is a very useful and versatile tool almost any model railroader should have. There are many attachments, bits, saw blades that can be used.

The speed control failed after a number of years and Dremel was very helpful on getting the replacement speed control.

Many parts can be found in big box and small box stores. I am fortunate to have a small hardware store in my town with many bits. Amazon.com will have a good supply. I mostly buy anything though Amazon and once in a while, ebay. You just have to know how to shop.

Practice makes perfect and searching with Google or You Tube will pull up an amazing amount of links if you do not have to be led by the hand.

Dremel

There are some things that are nearly impossible to do without a tool like the Dremel.  A very versatile tool, I have two so that one can remain mounted in my Dremel Workstation and I have another for freehand use.  I also have and use the flex shaft quite often.

But beware imitations

Thanks for all the advice so far...now one more question

Is there any certain model that you recommend?  Would this work:  http://www.amazon.com/Dremel-100-N-Single-Speed-Rotary/dp/B002BAHF64/ref=sr_1_11?s=power-hand-tools&ie=UTF8&qid=1381890255&sr=1-11&keywords=dremel+tool

No to single speed IMHO. Get a variable speed unit.

Would it work?

The Dremel tool I use is very similar to that, except for having a two position speed switch.  I find it immensely useful for a number of tasks.  So, yes, I believe that would work well for you.  I would also suggest investing in a set of different collets, or even a drill chuck, and a better variety of bits.  Especially handy would be another arbor, which will allow you to have multiple cutoff wheels at the ready.  I find that it's often faster to change the tool than it is to replace the wheel on an arbor.

Dremel good

but not good for cutting those windows. Build as someone suggested from parts sized to leave window openings when glued up. Better yet look at Walthers catalog and see if the kit buildings they make in that style would work. Variable speed corded model probably the best all around. I use a single speed because it was free and does the job. mostly used to cut rail gaps and grind out odd shapes with rotary bits.( had a nice long response all typed up but the software lost it when I tried to edit it so only you get the outline) ........DaveB

Dremel

Yes a Dremel is a must in the tool box. In fact I would get 2 one for the Bench and the other one Battery operated Variable Speed. With many many acressories that you will find helpful over your lifetime.     Kevin

Variable Speed

Get a variable speed.  35000 rpm is too much for many tasks.  And too fast for larger bits.

The flexible shaft is a really nice attachment.  Also my 10.8v battery powered is really handy around the layout.

Good luck

Speed control

I too have two dremels.  And speed control is a must. One has the speed control on it.  But my other one is older, and I have an even older Singer sewing machine foot speed control that it plugs in to.  Now, that is very, very handy.  But don't use it standing up (ask me how I know)! 

I have a dremel,

But I don't use it much.  Never seam to have the right bit!  For window openings nothing beats a nibbler.  Here is a link.  This thing is way faster and more accurate than a dremel and way cheaper.

Walthers has a kit that looks just like that building...

My Dremel

Is a Dremel 400 XPR (Variable 5000 to 35000) - basically similar to the model 4000. I don't think they are available in most places, but it was a full kit from Home Depot for just over $100 three years ago. There may be some in stock, but not at Lowes or Home Depot, unless in the dust covered racks in the stock room.

It came with a whole bunch of accessories, including many, many cutting bits, Multipurpose Cutting Guide (Kit – Model 565), etc. and the flexible shaft and a planar (good for smoothing bedroom door edges that don't shut well). Here is a pic from a review site (  http://toolmonger.com/2007/08/31/hands-on-dremels-xpr-400-series-kit/ ):

Not all 400 XPR kits include all the accessories - I bought the sabre saw attachment separately and my kit did not include the circle cutter guide.

I also bought the workstation stand - a very useful item - for about $50 at Lowe's.

Dremel is good, very good...

...but mine came with two speeds - ON and OFF.  I took a tip from my father who had something similar and wired in an inexpensive household lighting dimmer switch (the old kind with a twisty knob) - cost me all of $2.50, and now I have a variable-speed Dremel!  It worked great for me, but BEWARE - this is 110 volt AC, and if you're not familiar with wiring for AC, have someone do it for you who is knowledgeable.  That stuff can kill if mishandled.

One thing you can do with a Dremel...

Dremel tools are great for cutting, grinding, etc. - pretty much any intensive metal work, or when you want to remove a lot of material in a hurry.  But I recently discovered another useful thing I can do with it.  I can sharpen my miniature drill bits!  I broke one the other day, and of course I didn't have another of the right size.  This time, rather than throwing it away, I chucked it into a pin vise, put the cutoff wheel in the Dremel, and carefully ground two new flats on the bit.  It worked beautifully, and I won't be throwing away as many drill bits in the future!

No one should own just one Rotary Tool

Indispensable!

NO FOR WINDOWS

Yes, for everything else. Variable speed a must. I have used mine many times in getting household projects done as well. The cutoff wheels have saved my butt on more than one occasion.

PKS-Espee over Donner

Must-have item!

MIne was a Christmas gift from way back in the late 80's.  The variable speed is now really 3 speed thanks to wear and tear- off, half and full.  I spend most of mine at half, and that is a good thing to keep things like styrene from melting as you sand/grind.  I've also (tediously) done pre-holes for finishing nails around my house at times so as not to split the trim.  I recently got the 'workstation' for my Dremel- like a drill stand but also has a tilt feature so it can be used as a kind of chop-saw.  I angle-mount my Dremel and use it as a standing sander/grinder at times.

I noticed "the nibbler" suggestion earlier on page one here, and I got one at one of my local Radio Shacks- not the one a few blocks away but 3 miles away (always check online for which RS carries what, IMO) and that too is really the ultimate way to cut windows, after your Dremel has cut out an opening for it to go through of course.  I can't recommend that nibbler tool enough for that purpose, although I've yet to really find another one for it, except to help cut out a pick-up hole in a guitar's pickguard. 

Is this your first scratch-build?  Just asking.

If you work in electronics

I bought this today

... at Harbor Freight:

Probably quality is rock bottom, but is small and light. I will use it for light detail work. Cost $11 with taxes. Jose.
