It's a huge mixed-use residential building surrounded by pasture land. One can ride their bike from ground level right up to the penthouse at the 10th level. I Googled "8 House" and Wiki provided the following:</div><div><br></div><div>============ Copied material ==============</div><div>

This is achieved by stacking the various ingredients of an urban neighbourhood into layers. They are connected by a promenade and a cycle track which reach up to the 10th floor, allowing businesses and housing to co-exist.</p><p style="margin: 0.5em 0px; line-height: 17.9200000762939px; color: rgb(37, 37, 37); font-family: sans-serif; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255);">Thomas Christoffersen, BIG's partner in charge of the project, described the approach in more detail:</p><p style="margin: 0.5em 0px; line-height: 17.9200000762939px; color: rgb(37, 37, 37); font-family: sans-serif; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255);">The apartments are placed at the top while the commercial programme unfolds at the base of the building. As a result, the different horizontal layers have achieved a quality of their own: the apartments benefit from the view, sunlight and fresh air, while the office leases merge with life on the street. This is emphasised by the shape of 8 House which is literally hoisted up in the northeast corner and pushed down at the southwest corner, allowing light and air to enter the southern courtyard.</p><p style="margin: 0.5em 0px; line-height: 17.9200000762939px; color: rgb(37, 37, 37); font-family: sans-serif; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255);">============== End of copied material ===============</p><p style="margin: 0.5em 0px; line-height: 17.9200000762939px; color: rgb(37, 37, 37); font-family: sans-serif; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255);">Images of the project may be viewed at BIG's website by going to the year 2009 in the "Chronological" listings and clicking on the "8" icon.</p><p style="margin: 0.5em 0px; line-height: 17.9200000762939px; color: rgb(37, 37, 37); font-family: sans-serif; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255);">http://www.big.dk/#projects-8</p></div><br><div id="M2Signature"><div>-- </div><div>=== * ===<br>Rob Tom ADT1 <br>Kanata, Ontario, Canada</div></div></body></html>
