This comfortable, contemporary three bedroom home combines functionality with form, with visual appeal from the street and sympathetically sitting toward the south boundary that creates space for gardens and indoor/outdoor flow. The more complex shape means a higher form factor. The mono pitch roof efficiently sheds the strong Wairarapa winds
"Our eHaus is infinitely better compared to our previous 1970's barely insulated house! Our family and friends note the comfort, even though their homes are also comfortable but at a much greater heating cost.
