Building Cost + How It Impacts Design (An Architect's Guide) | Architecture Short Course (Part 3)

Building cost has a direct impact on our design and it's one of the most basic and obvious concerns for architects and clients. In this video I'll show you how I use it as a creative constraint that informs our building design.
Building cost is divided into two general categories: soft and hard costs. Soft costs are the indirect cost of design: architectural fees, consultant fees, permitting, financing, and legal fees. Hard costs are all the cost directly attributed to the construction of the physical building.
Early on in the design process we know little about the building and so we use square footage as a means for estimating the building's cost to construct. But square footage alone won't provide all the information we need to properly describe the cost of a structure, some spaces cost more to build than others. Factoring the square footage provides an added level of precision and allows clients and architects to better plan how design affects the overall budget.
Planning for unforeseeable conditions is important as well and I describe how much of a contingency to add to the project at each phase of the work.
Cost considerations are crucial to realizing both our client's project and our vision for the work in the world and this video shares the framework I use to get there.

I'm not an architect, but I need plans for a house I want to build. I've been watching all your videos so I can know how this is done. I'm so grateful for this knowledge. Sitting down with a professional and my crazy first sketches was fun. She asked me so many questions! I had photos of the site, which slopes, the views I wanted preserved, the things I want blocked. She was impressed. I saw how excited she was with my ideas and that's when I knew I was hiring the right person. The first guy I talked to didn't like that I wanted to preserve as much of the topography as possible. He wanted to bulldoze it flat to force the site to fit the structure. Saguaros don't grow overnight, they are hundreds of years old. 🌵

[@sabrinal6645]

Amazing paragraph, as an architect, I adore your passion for preserving nature!!

how did you start building and designing homes?

[@ErinStetzerHomes]

This is a wonderful resource. Building techniques absolutely vary and you're so right about your comments surrounding the budgeting process!

[@TheTerryJo]

FABULOUS. The knowledge you give, relaying it in a humble and thoughtful way, is a joy to listen to and a resource I will refer back to over and over as we look to build a lake house. Thank you so much.

[@Sexyboricuamejicana]

Just found your channel and as a non archyectoial person with a project and design in mind I am grateful for a the knowledge already saved a few videos to watch to educate myself and hubby on our vission design.

[@jaredcapp7716]

I wish all clients, builders and architects could watch this video. Great content, great presentation.

[@adapa22]

Excelent! I really don´t understand why they don´t teach this real world information in our Universities. Thank you for your autenticity and generosity.

[@UndercoverArchitect]

Such a fantastic run through. Love the idea of using 'factored' rates rather than changing the square foot cost per space. Great strategy Eric - thank you for sharing in such detail. For those watching in locations that use metric measurements, there's roughly 10 SF / 1 square metre. So multiply Eric's amounts by 10 (so $300/SQ becomes $3000/m2). And divide areas by 10 (so 400 SQ becomes 40m2).

[@30by40]

cheers +Undercover Architect...thanks for doing the mathematical translations...

[@WAJK2030]

Undercover Architect Thx! Now I can tell u guys, it's somewhere between 1600 and 2000€ a m², for a high standard building in Germany, in building costs. so something around 180 - 220 $ per SF ? Meaning to build in brick&mortar/concrete, 3-paned windows, floorheating, nice bathroom and so on. But without furniture. I wonder why stuff is so expensive at the US at your place?

[@craigtalbot607]

Thank you for sharing!! We all hate reality checks, but knowing what you’re getting yourself into early allows for realistic adaptation!!

Awesome info! So very helpful. Thank you!

[@kummer45]

This man has a deep comprehension of informed design decision making. The mathematics of budget translated into design are not discussed thoroughly in architecture schools. His video gives a good idea how to "CONSTRUCT" an excel sheet on modular design. The budget characterization of soft costs and hard costs provides a true sense of reality on the redaction of a liftoff. He manage to translate the plausible to the possible. The best strategy shown there was that each square foot needs to be heated, cooled down, maintained, illuminated and cleaned for many years. The author gives a strategy of percents describing energy consumption per space. This IS the basics of performance based design. His 'thesis' is based on a well known principle of parametric architecture done on the basis of budget percentages and distributions. His witty explanations of size estimation for a building with the totality of the budget provides less room for uncertainty. The dialogue between client and architect becomes accurate without misguidance or false heroics. I watched four times this video. This hits the nail.

[@mikeroe7943]

Having lived in older houses and watched their repairs, I've noticed how frequently the utilities and pipes were placed poorly, limiting remodel options or preventing repairs from going smoothly. Add to that the invention and addition of new utilities like television cable, and these homes could become a mess of exposed cables that the original builders never anticipated a need for. My college dormitory, for instance, was such a rats nest of ethernet cables and new plumbing that every hallway felt like a basement. I'd be interested to know if a video exists that explains a modern best-practices for something like home utility layout, and whether or not enhancing old homes with things like natural gas, cable, internet, and so forth has prompted designers to begin intentionally leaving space available for easy installation of new services as they're available/invented so that the building can more easily become modernized. For example, not making it nearly impossible to convert from electric to gas water heating.

you're quite welcome +Min Min...thanks for subscribing!

[@ErinDoughertyDistinctive]

Your comment about involving a contractor early on in the design process is right on point. Thank you for reminding people about the importance of involving a builder during design to help evaluate costs. I can't tell you how many times we've had potential clients bring us plans and they are shocked when we complete the cost estimating. They either have to make concessions to get the project built or scrap it completely. What a waste of time and money! Involve a builder from the start. Cost estimating is time consuming, and while we charge for this service, if a client understands the value of having a builder involved during design they will save time and money in the long run. We are the ones estimating projects every day and we have our fingers on the pulse of labor and material costs which are constantly fluctuating. Keep up the great work, Eric! May I add a link to this video on our blog? I think it is full of very useful information our potential clients could really use. P.S. Love the advice about being ruthless when evaluating what space you really need. We are currently remodeling a house half the size we are in right now with the intention of downsizing and the process is forcing me to really think creatively about the function of each space.

[@30by40]

Hi, Erin...Together we can help educate our clients that both an architect and a builder are an asset to their project! Would be happy to have you share the video (with attribution) on your site, that helps me continue to create these videos. All the best...

[@vp5134]

excellent discussion on costs. unfortunately at the early stages of a construction project, we often tend to be over optimistic... your video brings us back to the harsh reality of how budget will be the first limitation on creative design

Awesome video again Eric! I feel like this should be taught as part of the architecture course and find it very useful learning about the reality of what an Architect has to do. Thank you

[@30by40]

cheers +James Mason, I agree completely...it's our professional responsibility to help our client's understand the relationship between their budget, the design and ultimately the construction cost...not sure why it's absent in our education...

[@MaZEEZaM]

Given it's a key limiting factor in building of any kind you would think it would be an integral part of any Architecture course. Very informative video, I guess we have to go by the precedent of like builds.

[@HosamAlHassan]

you're amazing I'm sharing your beautiful lessons to many Architects

[@nephaisurlo]

What a cool and informative video! Thank you a lot! I haven't seen any of this topic before!

[@chadgould2567]

Great topic thank you! the important thing with any program goal to budget goal method is first to do it and second that it help to establish an appropriate amount of design slush needed to find the design. Its liberating to realize that it will be all wrong, as long as when you squint at it that it is generally right. I am curious if clients are getting the factors?... I wonder if it would be easier for them to keep the square footage pinned and apply factors to the cost side? One thing to also account for is the amount of perimeter envisioned. Stretching out and spreading the plan across a site and into multiple volumes will have an impact on the amount of foundations and area of insulated exterior walls etc. I recently blew past the budget goals on a project while hitting the SF targets and when I analyzed it there was something like 30% more foundation and perimeter wall than a the more compact design the builder typically executed. I have since started to apply a compactness factor to early budgeting worksheets to try and cover this when the project seems like it wants to sprawl. great job!

[@builderspluscustomhomesand2146]

Very useful. I learn so much from you videos. If you have not done so in another one of your videos, I would like to see you go through the same exercise but in the case of a renovation / remodeling project. I realize that some of the same principles would apply, still I think it would be interesting to see how and why the various steps would differ.

[@jeffstarzw]

from 12:13 to 12:25 is the most impressive statement of this video! Attention all Architects and Students, take heed! I am a QS with over a decades' worth of experience internationally, square footage is directly related to construction costs, not materials alone.

[@SlopChap]

Your video is the most comprehensive approach to figuring out build cost, the model is solid. However, your numbers are extremely high. I COULD find a builder that would gladly take $400/sqft but on the Super Premium side of things, I don't find anyone charging over $175/sqft. I know prices change with location and the model is workable with any amount, so no quarrel there. I'm not complaining or trying to say you are incorrect, I just can't believe anyone would ever get gouged that bad on price per sqft. Thank you for the video, it has been very helpful in determining a baseline cost in the building process. P.S. if you ever get a quote of $400/sqft to build a house, please reach out! I'll build it for $390! LOL Cheers

[@cindianderson9443]

[@romyvanhandley6432]

Great video. Thanks! :-)

[@richardsprow3418]

I’m a retired architect with 40+ years experience and the basic idea here is an essential step in any design project. You can adjust the factors and base SF prices to fit your situation. There are published guides you can get in a library (RS Means, for example) with cost factors for different building types. The SF costs reflect not only regional factors but types of materials and level of detail. For example, in another 30x40 video Eric discusses details he likes to avoid using typical residential baseboard and door and window trim, which are much more expensive to build because they eliminate a worker’s margin for error and require much more precise work. Those little architectural touches can have a big cost impact. This budget method should be taught in architectural school, which has always focussed too much on only design.

[@candisitati8727]

Richard Sprow hey am an architect student,did you enjoy your life as an architect?

[@richardsprow3418]

Candi Sitati : Great question! Yes, I enjoyed my long career as an architect, because the programming, planning and design process involves analyzing and then creating solutions that meet needs and constraints. The most memorable times are when a client said later ‘your design was a great solution, you had great insights’. I chose to specialize in healthcare projects, because I thought the complex problems were more interesting. My job as an architect took me to 40 states and a dozen countries all over the world. I worked for 9 different firms, including a few large international design firms, and I was never without a job, which is unusual in this field. I think you will enjoy architecture if you like problem solving and talking with people, going behind the scenes like a journalist to understand new organizations and their facility needs.

[@candisitati8727]

Richard Sprow thank you,I would like to achieve more than you got in this life science of architecture, and come up with new designs for the future,to increase in quality and to cut on cost,to make up a country full of cities with new designs for the market, environment and people

[@richardsprow3418]

Candi Sitati : Go for it Candi, I am glad you want to develop your skills and use them productively. One of the things I enjoyed was building useful long term projects like schools and hospitals. As you look for ways to reduce cost and improve quality, don’t forget to look at how real people and families use space and what they need. Good luck!

[@edgarteran1366]

Wouldn't be easier to implement BIM from the get go? Or at least use it to estimate more accurately... Thanks for all the effort you put on to these lessons, it really helps

[@30by40]

hi, +gabriel teran , thanks for sharing your thoughts. I'm really interested to see where BIM takes the industry with respect to estimating in the next decade, however, with respect to the context of this video it's important to note a few things: 1) As an architect, I don't want to contractually own the estimate (or any liability associated with it) as part of my scope of work. I want to develop a reasonable methodology for aligning the client's budget with an estimated cost to construct, but there are too many factors out of my control that prevent me from bearing the responsibility an accurate estimate. Ideally, I want a contractor as a partner who will assume responsibility for determining the building cost. This makes sense as it's their labor, their subs, their material suppliers that will handle executing the work. The framework I shared should get you close (in a residential setting at least) and from there you can begin designing. 2) Early on (before you start drawing/designing) there is no BIM involved yet. You want to set the direction, scope and size and these rough estimates help you do that. Once you build the BIM model and have information to draw upon, it will no doubt be useful for estimating (depending on how granular your model is). It might even serve as an alternate revenue model for architects (additional service) to provide to the contractor. There are inherent liability issues with these kind of arrangements (accuracy, errors, omissions) so be sure to discuss with your insurance provider. Hope that helps!

BIM will definitely be incorporated in the future of construction. Who is responsible for the quantity is a problem. The priority hierarchy right now is contract, specifications then the drawings, BIM at the end. Once we go 3D only with no 2D drawings in the future, we may just state in the contract that the contractor is responsible for all the quantity even it's in the BIM or not, so it is onto the contractor to look at the BIM and its quantity and decide if there is anything missing.
