Welcome to 11522 Niwot Rd.

This 35.09-acre estate, located in unincorporated Boulder County, features a spectacular setting with unobstructed epic views of: Panama Reservoir, the iconic Boulder Flatirons, and the snowcapped peaks of the Continental Divide.  The homesite features a custom energy efficient home, designed to capture the entertaining and dynamic views of the seasonal changes only found here in colorful Colorado.  Enjoy watching American Bald Eagles and migratory water birds such as Canadian Geese and American White Pelicans on the lake from the comfort of your living room and abundant outdoor spaces.  Watch as the prairie comes alive in the springtime and as storm clouds build up over the Indian Peaks and roll across the sky above the foothills.  Like living through a looking glass, this setting offers magical scenery with something new to keep your interest all year-round. 

The home was built in 1992, designed by the current owners with plans drawn by Norman J. Haun & Associates.   This is a 2-story home with functional emphasis on main level living.  The main level features the primary bedroom with a large 5-piece private bathroom, and access to outdoor living space.  A large kitchen space thoughtfully planned out with plenty of built-in storage and ample counterspace to handle large family gatherings and seasonal demands of a hobby farm.  The formal dining room and living room are open, contiguous space, although natural separation is apparent by design.  The sunroom is located directly off the dining area.  Additional rooms on the main level include: (1)  A den featuring a wet-bar, home audio controls, built-in cabinetry, a West facing bay window and access to outdoor living space; (2) A large bonus room with a wood-burning stove, utility sink/wet bar, West and South facing views, and access to outdoor living space, can be used as a family room game room or whatever suits your taste; (3) Interior hobby shop with built-in cabinets, work bench, 220V power, a wash-tub sink, and access to the 2-car attached garage; (4) Utility and control room for the heating system; (5) Powder room (1/2 bath); (6) Mudroom/Laundry room with exterior entrance, Washer, Dryer, Wash-tub sink, shower stall, built-in cabinets and counterspace.

Access the 2nd floor from a radial wooden staircase, custom designed with axe-handle balusters and craftsman hardwood-cased newel posts.  The upper-level features 3 bedrooms and a shared full bathroom.  The largest of the 3 rooms upstairs features views to the West and South, the mid-sized room has primary views of the lake and peekaboo views of the mountains, the smallest room upstairs features views to the North and of the private pond.  Two rooms contain interior vented windows to take advantage of the passive solar air movement inside the home.  Heating for the upper floor is also in-floor radiant.

The design incorporates passive solar elements, for heating and cooling.  Thermal insulated glass facing South, vented skylights, and extended roof lines to provide seasonal light and shade in the right areas.  In-floor radiant heat for the home is provided by dual sources of solar heated water and boiler, with a 450-gallon storage tank.  The home is constructed of brick, thermal insulated glass, and features a well-insulated metal roof (new in 2020).  The current owner reports that the interior temperature of the home never exceeds 80 degrees even in the late summer months.

The home also comes with a 3.48 kW PV system to supplement energy use.  The panels were upgraded in 2021 to modern, more efficient panels with microinverters onboard to eliminate the need for a separate power inversion system.

Water Rights:

  • 22 shares of the Boulder-Whiterock Ditch company stock. 22 shares x 2.0 Ac-ft  =  44 Ac-ft. One Ac-ft equals 20 inches of water, so 880 inches of water is the total yield in inches. Each share of this water right yields 2-acre-feet of water.
  • In the spring of the year and usually up until July 1st B&WR shares can yield Free River water.  Each share can yield up to 2.5 acre feet of water before the land owner begins to pay for additional water taken from the river. In the spring the land owner can call for water from the river. Normally I ask for 80 inches of water per 24 hour period (I can handle up to 100 inches but that stresses the system so I stick with 80 inches).
  • To irrigate the land, it takes 80 inches for approximately 6 days. ( 80 inches x 6 days = 480 inches) ( 1216 total inches will irrigate the land 2.5 sessions per year. Plus I usually get one session of free water in the spring so 3.5 sessions per year total) a session includes filling the pond plus irrigating the surrounding land.


  • Mature trees, flowering fruit trees, flowering shrubs, varietal flowers, mature concord grape vine covering the entry pergola.
  • 1-acre pond featuring a wooden bridge across the middle, irrigation pump.
  • The property consists of a home module of approximately 6 acres. Planted in Kentucky blue grass around the home module and irrigated with pond water and a sprinkler system fed by a pump in the pond. The trees and bushes around the home module are all drip irrigated. A series of manifolds exist that can be controlled by the owner. This system is fed by the pond pump which has an AC pump with controls in the mechanical room in the house. There are multiple emitters around each tree and or bush in the 6-acre module including the large barn. Each emitter drips 1 gallon of water per hour. In the 6-acre module there is also a garden which can be sprinkled with pond water as needed. The other portion of the 6-acre of the home module is planted in drought tolerant crested wheat grass which turns green with rain and brown without rain. 
  • 17 acres +/- planted in grass hay, irrigated by agricultural B&WR water which is delivered to a distribution box along the northern boundary of the property. The landowner calls for the water and the ditch company delivers it. The owner then directs the water via a distribution box and gated pipe to the east, west or south depending on the need, and  non-gated pipe directly south to fill the pond.  The distribution box is shared with the neighbor to the east and so coordination is necessary when ordering water.
  • 4 acres +/- of mature trees planted as a wind break along the northern boundary. The trees and bushes that make up the wind break have been drip irrigated for many years but are now on their own.
  • 5 acres +/- along the eastern boundary which can be irrigated but is just simply planted in crested wheat grass which is drought tolerant but can be irrigated and must be mowed.
  • 3 acres +/- at the northwest corner of the property, planted with lilacs and is irrigated with the gated pipe running from the bunker to the west.
  • A series of values exist to direct the water at the owners wishes to the west 6 acres, The 17 acres of hay in the middle so to speak, and 5 acres along the east boundary of the property. This section is irrigated with 8 inch pipe running north south and is controlled by the owner as needed.
  • The pond is about 1.1 acres and is part of the 17 acre hay field. The pond is approximately 8 feet deep at its deepest point and has a bridge across the middle of its figure eight shape. The south lobe is the deepest and the fill occurs in the north lobe.
