Hobbit Hollow for Sale in Upstate New York

August 13, 2018 at 4:24 pm

Hobbit Hollow

As seen on various media recently, The Hobbit Hollow resides in Pawling, a town in upstate New York, and is now on the market for sale.

A true labor of love from a J.R.R. Tolkien super fan, civil engineer Jim Costigan recently completed his own Hobbit hole, started almost seven years ago.  Jim reluctantly said, “I’ve got to take the Ring and throw it into the fires of Mordor.”

Jim’s cast-in-place concrete roof, earth sheltered Passive House is very energy-efficient and he says it uses 90 percent less energy to heat and cool it compared to the average home.  Along with a beautiful living roof, Hobbit Hollows’ sustainable features comprise low air infiltration; super-insulated walls, roof, and floor; high-performance windows and exterior doors; energy recovery ventilation; and ADA accessibility both inside and out.

Yet, the reason the Lord of the Rings (LOTR), The Hobbit, and The Silmarillion enthusiast built a Hobbit hole was for love.  First, Jim built a smaller shed as a tribute and then this 1,500 square-foot home with all of the modern trimmings as his interpretation of a Hobbit abode from the Peter Jackson movie trilogies.

“The house in the movie was off the charts. That’s what really inspired me, how do you build a house that’s like that?” ~ Jim Costigan, News12 Westchester

Well, Jim has a blog devoted to answer that exact question – visit My Hobbit Shed and especially see beautiful photos of his finished Hobbit Hollow in the Construction Blog page.  Here are just some roof construction details:

“In addition to tapering the roof slab and thickening the walls and floor, the engineering “wizard” called for the wall-to-arched-slab intersection to be poured monolithically (the roof slab was poured in stages to prevent cold joints from occurring in the tapered slab’s more structurally critical thickened portions). First, they poured the thickened edges (10 feet up the roof) along the length of the building, then finished up with the remaining center section. Continuous “shear keys” were formed in both concrete walls (at the footing and roof-to-wall junctures) to prevent lateral movement.” ~ Forming a Hobbit House Roof, JLC Online

Just like Aramis and my favorite late night show host, Stephen Colbert, I’m a huge LOTR fan, too (OK, I’m certainly not as nerdy as Stephen – I wish I were, but I’m not).  As many of you know, we visited the Hobbiton™ Movie Set in New Zealand in 2014 and it was truly an experience of a lifetime – read my Greenroofs.com Explores Middle-earth at Hobbiton, NZ.

In Jim’s honor, we are once again featuring the Hobbiton™ Movie Set as our current Project of the Week:

Obviously, as an equally obsessive greenroof devotee and promoter, I just had to share Jim’s passionate construction journey and story with you!

Designing with nature and not against it:

Translation of the Spanish Interview with Linda S. Velazquez in El País on the need for green architecture in cities

Under the header of “Urban Beings” in the “Green Cities” section, here’s my translationOf course, they edited quite a bit and didn’t include all of my answers, but so be it.

NOTE: El País didn’t use any of the photos or graphics I sent, and in fact put one in of an interior courtyard landscape above – is it a greenroof?  I don’t know.  All of the photos below are my own placement!

Q & A Translation by Linda Velazquez

Designing with Nature Linda S. Velazquez Interview El País Translation

Here in Alpharetta, GA at Rock Mill Park where I designed the Greenroof Pavilion & Trial Gardens.

Linda S. Velazquez is a member of the American Society of Landscape Architects (ASLA), GRP, LEED AP. She is also the founder and publisher of Greenroofs.com (1999) and design consultant at her company Sky Gardens Design (2004). Linda studied landscape architecture at the University of Georgia (2000).

Linda writes and reports extensively about greenroofs and living architecture and has presented across the globe. Linda’s role as Greenroofs.com publisher affords many opportunities to promote the industry.  She has collaborated on numerous books including Green Cities in the World, Vertical Garden City: Singapore, and The Rise of Living Architecture, in addition to journals, magazines and online media.

Q: From your experience as a pioneer in the analysis and dissemination of urban green infrastructure, how do you perceive its evolution in the last few years?

A. In my opinion, I believe our green architecture industry and market continues to grow each year because of the increasing general public interest and acknowledgement of important projects along with their associated multiple benefits – both public and private. We must also recognize the accomplishments of innovative leaders within the industry and design fields, businesses, and government at all levels who have promoted the idea and its progression further.

In the last 20 years we have seen dynamic and avant-garde designs that have drawn great attention to promote the greening of the planet with the integration of green: bioclimatic, biodiversity, biomimicry and sustainability.  Of course, construction follows financial cycles and we had a few years with fewer projects completed, but many people around the world are interested in green technologies, whether renewable energy or low impact development including green infrastructure like greenroofs and walls, and much more.

Q: Who or what are the most dynamic elements?  Architects, designers, entrepreneurs, institutions, NGOs …?

A: I think it has been a combination of experts, visionaries, and multidisciplinary professionals who have spread greenroof technology, at least here in North America.  As for early completed projects, I would have to credit collaboration between architects like Moshe Safdie and landscape architect Cornelia Oberlander with the government of Vancouver, B.C. in Canada with its spectacular Public Library (1995, currently under a major renovation to create an accessible public roof garden space).  Another innovative architect is William McDonough who worked with entrepreneurs such as the GAP in San Bruno, California (1997); the City of Chicago with its City Hall (2001), perhaps the most famous greenroof in the U.S.; and the Ford Motor Company with its River Rouge Truck Plant in Dearborn, Michigan (2003), which had the distinction of being the largest greenroof in the world for a few years, with 454,000 square feet.

In the United States in 1997/98 the pioneers who helped me tremendously were civil engineer Charlie Miller of Philadelphia, Pennsylvania; landscape architect Tom Liptan of Portland, Oregon; and the German environmental engineer Katrin Scholz-Barth who lived at that time in Minnesota.  Also, ASLA began writing on the subject during that time frame and, with thanks, I began to discover and research further, culminating in Greenroofs.com in 1999.

Q. In your presentation at the WGIC Berlin 2017 Congress, you identified the 10 most recent trends in greenroofs and walls. What are the underlying market drivers?

Designing with Nature Linda S. Velazquez Interview El País Translation

A. Each trend in greenroofs and walls has several underlying factors depending on the location of the project: variables such as the needs and desires of the public and governments or the client / owner, what type of buildings are popular or necessary, different uses of a structure, aesthetic tendencies, the weather, the available products or materials, etc.

With Greenroofs.com’s annual compilation of the most popular trends, the “Top 10 List of Hot Trends in Greenroof & Greenwall Design” (since 2007), we try to highlight cutting-edge structures and designers who are outstanding, inspiring, and magnificent – underlined by the exceptional green vegetation covering the building.

Q. What effects can green infrastructure have on the population?

A. Instead of using “gray” infrastructure such as concrete, asphalt, or hiding rainwater in underground pipes, detention ponds, etc., designing with nature instead of against it – using vegetation and natural ecosystem services – offers a multitude of beneficial opportunities and associated effects to improve a city or locale. The integration of nature into the urban fabric produces a wide spectrum of environmental benefits for the flora, fauna and human communities of our planet.

Green infrastructure’s greatest potential lies in the ability to cover impermeable surfaces with permeable plant material. Using plants with engineering systems for stormwater management results in cleaner, fresher water and at the same time reduces the volume intensity that eventually falls on the streets. This immensely ameliorates a city, which is mostly impermeable, during heavy storms, when there may be overflows of the sewer system. Green infrastructure also reduces the urban heat island effect, which can dramatically increase temperatures due to lack of trees, plants, and green areas in cities, affecting the health of many people.

We can re-introduce native or sometimes even endangered plants by planting roofs and walls and green facades. At the same time, this attracts wildlife back to our cities like bees, butterflies and birds. We all know that seeing and being in nature is beneficial to human beings because of biophilia, the innate attraction in our biology to connect with nature. For example, nature helps us psychologically, improves the recovery of patients, and we rejoice within its natural and open spaces.

The creation of green spaces in a city is extremely important but sometimes there is no where to build a park or vegetable garden. Why not put it on top of a public building? And we must not forget that sometimes the green infrastructure costs much less than the gray infrastructure because we are using natural systems. If the cost of building a greenroof, for example, is more expensive at the outset, it has to be understood that life-cycle costs will reduce the final cost because of lower replacement costs because it will last double, triple, or perhaps even longer. Also, the use and energy costs of the building will decrease while at the same time a fifth facade has been created for the building – a new roof or wall space previously not utilized for the use of the owner or the public.

Finally, using a variety of low impact development techniques can reconnect people with nature. When all the environmental, aesthetic, emotional, and economic benefits are added, we can see that green infrastructure offers sustainability benefits to many. Implemented on a local or intermediate scale, green or biophilic architecture can improve the health and well-being of a community, country, and our planet Earth.

Q: With your international vision, what are the most dynamic cities in the implementation of green infrastructure and what are their drivers?

Designing with Nature Linda S. Velazquez Interview El País Translation

A: It is impossible to talk about the most dynamic cities and not start with Germany in general, since many cities like Berlin, Munich, Stuttgart, and others have been leaders for the last 50 years. At least 48 German cities provide financial support for greenroofs. Around 35% have integrated greenroofs as part of their regulation, establishing around 86 million m2 of greenroofs which represent 14% of the total roof area of Germany. And they have established professional associations and organizations for the study of materials and best practices, such as the FLL (Forschungsgesellschaft Landschaftsentwicklung e.V.), FBB (Fachvereinigung Bauwerksbegrünung e.V.), and DDV (Deutscher Dachgartner-Verband), to name a few.

There are other numerous cities in the world that stand out with integrated green construction including Chicago, Basel, Portland, Toronto, New York, Linz, London, Paris, Mexico City, Shanghai, Washington, DC and the area, Milwaukee, Bogotá, and lately Madrid and Barcelona. American states like California and Pennsylvania have also done many projects. My favorite leader is Singapore, an island nation that currently has more than 720,000 m2 of greenroofs and over 50,000 m2 of green walls with plans for 2 million square meters of skyrise vegetation by 2030.

Q: Could you provide some advice on measures we can take to improve urban dwelling?

A: We need to find or identify local leaders to talk about the topic of greenroofing and other greening opportunities and how to implement policies and strategies to encourage project stakeholders to build with green infrastructure. We still need to inform the public and various governments of the benefits so they understand the importance of protecting the natural environment and improving our construction practices using green infrastructure. As designers and other project principals we need to inform our customers why and how to do achieve this. And, we have to find ways to lower the prices of greenroofs and walls, either through industry or with the support of governmental incentives, tax exemptions, subsidies, etc. Green infrastructure should be considered first, whenever possible, within our built environment.

Q: The well-being of city dwellers requires action in different fields. Could you give us your opinion on the importance of biodiversity, food security, a healthy environment, water management, energy savings, and creation of green spaces and recreation?

ACROS Fukuoka Prefectural International Hall by Emilio Ambasz & Associates, a perfect integration of green over gray.

A: My academic background is landscape architecture. We recognize that our Earth is limited in its natural resources, and we have to protect all of us: animals, plants, and humans. We are as one, living and sharing an ecology that is this planet. We must bestow the heritage of a healthy and sustainable land to our children, grandchildren, and great-grandchildren. The Earth is not ours to plunder, but our planet to sustain and protect for generations to come! With all my being, I believe that, in part, this is possible with architecture and design that is ecological and sustainable. Urban greening diminishes the effects of the built environment and promotes a strong and beautiful green infrastructure, flourishing and healthy.

The People’s Climate March in NYC on September 21, 2014 and the Movie “Disruption”

September 11, 2014 at 3:55 pm

September 11 – today marks the 13th anniversary of the multiple horrific 9/11 attacks here in the U.S.  May we always remember and honor those lost.  On a more positive front, we’re thinking about a world issue and things we can do about it around the globe, and specifically in New York City:


Climate change is one of those hotly debated subjects with so many different points of views, from the sublime to the ridiculous, from fanaticism to complete denial. But I would have to believe that most of us in the living architecture industry have an environmentalist bent and can appreciate the seriousness of this potentially larger-than-life matter at hand.

World leaders will be gathered in New York City for the landmark United Nations Climate Summit 2014 on September 23, 2014 to address the climate crisis where UN Secretary­-General Ban Ki-­moon will urge governments to support an ambitious global agreement to dramatically reduce global warming pollution.


Are you aware of the People’s Climate March in NYC on September 21?  I wasn’t, but it was brought to our attention by our long time Student and Research Editor, Christine Thuring.  In anticipation of the UN Climate Summit, 1,000+ organizations are partnering on the peaceful March, accompanied by solidarity marches around the world.  Businesses, unions, religious groups, environmental groups, schools, social justice groups, and more are participating, including 350.org and Avaaz.org.  You can sign up at both organization for updates and sign a petition in support of climate change.

“There are several different bodies that are convening to collaborate on the People’s Climate March, including local New York-area community groups, international NGO’s, grassroots networks, churches and faith organizations, and many more.

Because this is a “movement of movements” moment, the People’s Climate March is being organized in a participatory, open-source model. This means that there isn’t a central “decision-making” body or single coalition. Rather, groups and individuals are collaborating with some basic shared agreements around respect, collaboration, trust, and many are using the Jemez Principles of Environmental Justice.” ~ PeoplesClimate.org

Released on September 7, 2014, a supporting film that you may be interested in seeing is ‘Disruption’ A Film by Kelly Nyks & Jared P. Scott.


The Synopsis is below:

“‘When it comes to climate change, why do we do so little when we know so much?’

Through a relentless investigation to find the answer, Disruption takes an unflinching look at the devastating consequences of our inaction.

The exploration lays bare the terrifying science, the shattered political process, the unrelenting industry special interests and the civic stasis that have brought us to this social, moral and ecological crossroads.The film also takes us behind-the-scenes of the efforts to organize the largest climate rally in the history of the planet during the UN world climate summit.

This is the story of our unique moment in history. We are living through an age of tipping points and rapid social and planetary change. We’re the first generation to feel the impacts of climate disruption, and the last generation that can do something about it. The film enlarges the issue beyond climate impacts and makes a compelling call for bold action that is strong enough to tip the balance to build a clean energy future.” ~ WatchDisruption.com

We watched the 52:27 movie last night on Vimeo, but you can also watch it on YouTube, on WatchDisruption.com, or even here below:

Is it worth watching?  Definitely.  Is it a scientific documentary per se?  No, not quite, it’s more political in nature.  It does, however, contain enough condensed factual information to make its point.  I believe it assumes that the people who are watching it are pretty familiar with the multitude of years of climate change studies, research, etc., available to us.  Is it full of opinion and emotional heart-pulling calls to action?  It sure is; I believe that is its main purpose, and it does a great job.

The filmmakers are not trying to convince people of climate change here but asking us to join in and do something about it, specifically with the upcoming People’s Climate March in New York City where potentially hundreds of thousands of like-minded people will do the same.

I strongly believe this issue not only needs to be addressed in our lifetimes, but now.

By the way, there is a shot of solar panels galore on top of greenroofed buildings in Germany at about the 41:19 mark:


Please share your thoughts!
