owing cost(자금조달비용)의 이해

Posted by – June 26, 2009

개발사업 시행예서 가장 중요한 부분이 owing cost(자금조달비용)이다. 개발초기비용을 전부 자기자본으로 부담하면 좋겠지만, 그렇게 할 수 있는 기업이 없을 뿐더러, 그렇게 해서도 안된다. 왜냐면, 100%자기자본을 들여서 사업을 시행하면 금융비용이 줄어 사업수익은 증가되나 사업소득세(법인세)가 증가하여 ROE(자기자본순이익률)이 현저하게 떨아진다. 내가 투자한 돈에 비해 남는 비용이 얼마안된다는 이야기이다. 따라서, 자기자본을 최소한을 들이고 사업을 하는 것이 현명하다. 통상적으로 사업을 시행하기 위한 적정투자비는 초기사업비(토지구입비용)의 30%가 적정하겠지만, 우리나라에서는 10%이하의 자금으로 시행하는 경우가대부분이다. 이는 우리나라 주택정책의 특수성으로 인하여 제도적인 특혜가 있기 때문이다. 이에 무분별한 시행으로 인하여 주택시장의 과잉을 초래하기도 하였다.

 요컨데, owing cost의 절감은 사업성공의 필수 조건이다. owing cost를 결정하는 중요한 기준은 기업의 신용등급이다. 국내에서 기업의 신용등급을 평가하는 회사는 몇군데가 있다. 기업신용등급의 공시에 따라 금융기관의 대출 및 채권발행시에 금리가 결정된다. 대부분의 시행사는 프로젝트를 위한 하루살이 기업이라 기업 신용도가 전무하다. 따라서, 시공사의 연대보증입보가 필수적으로 필요하다. 결국, 주관시공사의 신용등급에 따라 owing cost가  결정된다.

조달상품별 owing cost를 비교하면, ABCP(5%대) <ABS(7%대) < 은행대축(8%대) < 저축은행(10%이상) 이다.
 결국, 신용등급이 양호한 건설사와 함께 사업을 시행한다면 owing cost를 낮출 수 있다. 다만, 공사비가 높아지겠지만, 최근에 많이 발행되는 1년만기 ABCP금리를 보면 그 건설회사의 신용도를 가늠해 볼 수 있다.

1년만기 ABCP금리
포스코건설 5.5%
삼성물산 5.5%
롯데건설 5.7%
두산중공업 7.58%
현대건설 8%
GS건설 8.2%
대우건설 12%

ROE와 ROI

Posted by – June 26, 2009

ROE(Return on Equity) : 자기자본 수익률 = (당기순이익 / 평균 자기자본)  * 100%

ROI(Return on Investment) : 총투자자산 이익률 = (당기순이익 / 총투자자산) * 100%

즉, ROE(자기자본 수익률)란, 1년동안 벌어들인 당기순이익을 자기자본(순자본)으로 나눈 것이다. 이 비율의 의미는 주주(투자자)가 투자한 자금으로 어느 정도의 수익률을 내었는가? 를 나타냅니다. 그러므로, 이 비율이 미미한 수준이라면 남는 것이 별로 없다는 뜻입니다. 따라서, 투자자들이 투자한 돈으로 괄목할 만한 성과를 못낸다면 투자자는 이런 회사에 투자를 하지 않을 것입니다. 차라리 은행에 돈을 넣어놓고 약간이지만 이자수익이나 챙기는 것이 더 현명할 것입니다. IRR도 그러하지만, 최소 수익률은 은행저축이자 이상은 나와야 하겠지요.  선진국에서 이 수익률은 최소 10% ~ 15%정도는 되어야 투자를 고려할만 하다고 합니다.  주의할 것은 부채가 많은 기업이 자기자본 수익률이 높을 수 있다는 것입니다.

A사 총자산2190억원(부채970억원,자본1220억원)  당기순이익(NOI) 260억원

          A사의 ROE = 21%, ROI = 11%

B사 총자산1670억원(부채730억원,자본940억원)     당기순이익(NOI) 110억원

          B사의 ROE = 10%, ROI = 6%

Yesterday I posted a tiny tree house hotel in Sweden, today I’m posting a tiny underwater house in Sweden. (I guess I’ve got to get myself to Sweden.) This little hotel room floats in Lake Mälaren near the town of Västerås, Sweden. Basically the little red house sits above the waterline and is the access point for the bedroom that’s below the water. It’s the brainchild of artist Mikael Genberg who was also the man behind the Woodpecker Hotel. And I thought I had a wild imagination, LOL. Thanks again to Marti for passing this one onto me too. Great stuff!

Rolling Huts

Posted by – June 24, 2009

  •  LEAD ARCHITECT : Tom Kundig, FAIA
  • LOCATION & YEAR  : Mazama, WA, 2007

Responding to the owner’s need for space to house visiting friends and family, the Rolling Huts are several steps above camping, while remaining low-tech and low-impact in their design. The huts sit lightly on the site, a flood plain meadow in an alpine river valley. The owner purchased the site, formerly a RV campground, with the aim of allowing the landscape return to its natural state. The wheels lift the structures above the meadow, providing an unobstructed view into nature and the prospect of the surrounding mountains.

The huts are grouped as a herd: while each is sited towards a view of the mountains (and away from the other structures), their proximity unites them. They evoke Thoreau’s simple cabin in the woods; the structures take second place to nature. Rental information for the Huts is available at  www.rollinghuts.com [From to :  http://www.tinyhousedesign.com]

New Take On Rolling Tiny Houses

Posted January 28th, 2009 by Michael Janzen and filed in Projects

My buddy Ryan spotted this project in a recent WSJ (Wall Street Journal Magazine), a surprising place to find an article on tiny houses. These were designed by architect Tom Kundig and serve as guest houses on a remote property in Washington State. The 44-acre property had a zoning issue and a grandfather clause saying that only RV hookups were allowed. Instead of trying to get a variance approved the owner and architect decided to put the houses on big steel wheels and plug the houses into RV hookups. This is an excellent example of how local lemons (zoning requirements) can be turned into lemonade (out-of-the-box solutions).

The cost of each building was about $75,000. The interior square footage is 200 square feet with an additional 240 square feet on the exterior deck. The structure is a mixture of steel, glass, and wood. The end result is a very spacious loft-like modern building.

While I think these are a beautiful work of architecture I’m not sure it’s the most practical design in terms of low cost or low impact. I am certain that there are tons of excellent ideas here though, for example the wheels to circumvent a zoning restriction and the open steel structure in a tiny house. The roof is also designed to hold snow adding to the insulation. I just hope the clearstory window is super insulated or all that heat will just float away.

See this project on the architect’s website. Be sure to poke around their website. I noticed quite a few innovative looking smaller homes.

The Eco-Shed – Above Snug Cove Village on Bowen Island, B.C

Posted by – June 24, 2009

Posted July 18th, 2008 by Michael Janzen and filed in Projects

Curious about experiencing green living in a tiny home without building one yourself? Here’s a little place that’s a little off the beaten track up on Bowen Island in British Columbia. It’s called the Eco-Shed and it’s a tiny house available for rent on a nightly basis.

It’s a showcase for living lite and building green that’s built with a passive-solar design, lots of reclaimed and FSC-certified wood, super efficient fixtures and windows, and nontoxic materials and finishes. The interior is also peaceful and quiet thanks to the spray-foam insulation system and excellent ventilation.

For all the details, rates, location, and reservations see the Eco-Shed website. Photo credit to Eco-Shed.

Woodpecker Hotel – Tiny Tree House Hotel in Sweden

Posted by – June 24, 2009

Posted February 9th, 2009 by Michael Janzen and filed in Historic, Just For Fun

The Woodpecker Hotel is a tiny tree house hotel room in a park in Sweden. It’s 13 meters up a tree, yep over 40 feet in the air. You get to it by climbing up a wobbly rope ladder. The tree is a 130 year old oak in the central park of Västerås which is near Stockholm, Sweden. Luckily there is a small toilet up there so you won’t need to repel down in the middle of the night to use the potty. There’s also some simple IKEA furnishings and small library in case you get tired of the view and would rather pick up a good book. Below are some great photos I found on flickr taken by Annie. Thanks again tipping me off to this cool tiny tree house Marti!

Haus R , Nürnberg

Posted by – June 24, 2009

 

Das Grundstück befindet sich am Ortsrand einer dörflichen Siedlung im Norden Nürnbergs. Die Zufahrt erfolgt über eine nördlich gelegene Privatstraße. Der Entwurf zeichnet sich durch eine klare Nord-Süd Orientierung der unterschiedlichen Nutzungen aus. Die Funktionen Wohnen/Arbeiten, Kochen, Essen befinden sich im EG, Schlafräume und Bäder im OG. Die Wohn- und Schlafräume liegen nach Süden zum Garten hin, die Erschließung befindet sich im Norden. Entsprechend der Grundrissdisposition sind die Fassaden des zweigeschossigen Massivbaus unterschiedlich konzipiert. Im Süden sind raumhohe Schiebefenster abwechselnd mit geschlossenen Wandteilen über einen verschieblichen Holzlamellen- Sicht/Sonnenschutz bündig in die Mauerwerksfassade integriert. Die Nordfassade ist relativ geschlossen gehalten. Fenster im OG, die sich über Klappflügel aus Holzlamellen verschließen lassen bilden ein ebenfalls bündig in die Fassade integriertes Lamellenband. Lediglich der Eingang ist über ein räumlich gestaltetes Element plastisch hervorgehoben. Ein sehr transparent gehaltenes Treppenhaus erzeugt einen großzügigen Eindruck beim Betreten des Hauses. Die für den Ausbau verwendeten Materialien reduzieren sich auf Holz für Fenster und Türen (unbehandelte Lärche)und Bodenbeläge (Buche), weißen Putz für Innenwände und anthrazit gestrichenem Stahl für die Treppe.

Another Way To Build With Pallets [pallet pavillion]

Posted by – June 24, 2009

Posted December 7th, 2008 by Michael Janzen and filed in Concept

One of my readers, EJ, sent me a link to this project. It’s an alternative way of building a shelter out of shipping pallets. This one was built by students at the University of Biberach in 2005. It was a concept for a pavilion intended for participants of sporting events. This one measured 6 meters high, 8 meters wide, and 18 meters long. So not exactly a tiny house, but you can see where I’m going with this.

 For more information see this original article : below

Rauminstallation mit Paletten für die SKI-WM, Oberstdorf

Folgende Parameter sollten bei der Entwicklung beachtet werden:
- Das Material sollte wenn möglich Holz sein, da die Region sich sehr stark mit diesem Baustoff identifiziert.
- Der Pavillon soll unter der Zielsetzung der Nachhaltigkeit entworfen werden, dass heißt ohne große Abfälle wieder abgebaut werden können
- Der Pavillon muss im Wesentlichen von den Studenten auf- und später wieder abgebaut werden können.
- Die Rauminstallation soll einen besonderen „Ort“ schaffen, in dem sich Menschen gerne aufhalten und einen ungewöhnlichen Raumeindruck erleben.
- Der Pavillon soll im Rahmen der Ski-WM in Ergänzung der Villa Jaus ein Treffpunkt für Medien und Sportler nach den Wettkämpfen sein, ein Ort für Gespräche, mit einer besonderen Art der Bewirtung.Aus den selbst gewählten Vorgaben entstand bald der Gedanke die an vielen Orten gestapelte „Europalette“ als Baumaterial zu verwenden und sie den Menschen in neuer Verwendung vor Augen zu führen. Das im Normalfall lediglich als Hilfsmittel für den Transport anderer Güter verwendete Bauteil sollte in einem gestalterisch anspruchsvollen Zusammenhang gänzlich neu erlebt werden, um damit den Menschen aufzuzeigen, welche Qualitäten und Werte in Materialien stecken, die von uns oft etwas abwertend als reine Nutzprodukte betrachtet werden. Die Europalette zeichnet sich durch eine komplexe Geometrie von offenen und geschlossenen Flächenanteilen aus, die sich bei versetzter räumlicher Stapelung zu interessanten netzartigen Strukturen fügen. Diese Komplexität wollten wir nutzen, um daraus ein völlig neuartiges Erscheinungsbild zu generieren.
Zunächst wurde die geometrische Lage der Zuganker anhand eines Schnurgerüstes ermittelt, anschließend wurden die Zuganker in den Untergrund gebohrt. Nach jeweils 10 Schichten wurden die Gurte verspannt, In den höheren Lagen wurden die Paletten mit Hilfe von einem kleinen Autokran an Ort und Stelle gehoben und dann verteilt und befestigt. Die Konstruktion des gesamten Pavillons ist als „vorgespannte“ Raumschale zu verstehen, die mittels Bodenankern in den Untergrund befestigt ist. In regelmäßigen Abständen von ca. 2,5m sind die Paletten im Innern mittels LKW –Zuggurten zusammengespannt. Diese Vorspannung gewährleistet die Stabilisierung der geometrisch unregelmäßigen Form, wie bei der Vorspannung einer Kette .Die Zuggurte sind mittels örtlichen Bodenankern im Untergrund befestigt. Im oberen Bereich der Schale sind aus geometrischen Gründen horizontale Balken als Biegeträger zwischen die Schale als Dachkonstruktion gespannt, auf die dann die „Dachpaletten“ aufgefädelt wurden.

Abmessungen:
Höhe: ca. 6m
Breite: ca. 8m
Länge: ca. 18m

Material:
20 Zuganker
1300 Europaletten
100 Stck. Zuggurte a 6m

Beleuchtung: Innenstrahler mit blendfreien Reflektoren
