Originally the driveway on this project had been compacted gravel with poured concrete curbs on either side. In order to install pavers the top 3” of driveway gravel was removed. The disturbed gravel was compacted with a roller compactor. A one inch thick layer of bedding sand was placed on the gravel base. Pavers were installed by hand on the prepared base. Holland series pavers were installed in a herringbone pattern. This driveway was approximately 1525 square feet. Pavers were cut to fit the edges of the driveway. Polymeric sand, a compound to reduce grass and weed penetration of the pavers, was swept between the pavers. One of the advantages of using the pavers (as opposed to asphalt or concrete) is that if in the future a pipe needs to be laid under the driveway or a tree root lifts part of the driveway, the pavers can be removed, repairs made and then replaced. The final product is an elegant and functional driveway.

According to the designer, one of the most difficult parts of designing a new addition is the transition area between the existing room and the new addition. In this addition the designer achieved the success that she strove for. The new room blends seamlessly into the existing room. A corner cabinet was removed and the east wall of the existing family room was opened up. A small hallway was created to access the new master bedroom. A small 2’x5’ window gave the hallway plenty of light. A sconce to match the bedroom fixtures was also placed on the wall of the master entry. New cabinetry was added to the family room to house the media equipment. The cabinetry was recessed into the wall in common with the master walk in closet. Doors were built in the back side of the recessed entertainment center (accessed from the master closet) to facilitate installation or adjustment of all the AV equipment.

The porcelain tiles used in the master bathroom are Florida Legend in Olympic color. They are manmade although they appear to be slate. To give the room continuity and yet give it a distinctive flair different sized tiles were used. 18” tiles were used on the shower walls and also on the bathroom floor. Above the 18” wall tiles in the shower is a complementary accent of 2” United Desert Gold Quartzite slate and then 12” square tiles. A 2”x2” Florida Legend tile was used on the shower floor. The grout was Almond Accu color #984. The shower is handicapped accessible without a door or threshold. Two Grohe Arden shower heads and controls were installed with matching sink and tub faucets. An ADA approved white slatted phenolic folding shower seat was attached to the back wall. The seat can be folded up for ease of cleaning. A built in shampoo niche adds a distinctive accent. A Fiber Fab 710 jetted soaking tub with tile skirting and a Toto Drake 2 flush option ADA toilet complete the fixtures. A 4’x4’ skylight plus two large windows provide plenty of natural light in the master bathroom. The vanity countertop as well as window sills throughout the addition are composed of Caesarstone man-made silica composite material. The custom cabinetry was built with a recessed area under one sink so that a wheel chair can access the sink.

In addition to the radiant floor heating which offered a constant diffused heat, the owners wanted a source of immediate heat. A small Hampton Timberline H15 gas stove was installed. The fan option was added which significantly increases the heat distribution. The stove has an enamel coating and is very attractive. It was found to be useful upon returning from a length of time away from the home. To provide for air conditioning for the master bedroom suite an energy efficient Mitsubishi outdoor heat pump unit (MUY-GEO9NA) with an indoor head was installed. This Mitsubishi unit has an energy efficiency rating of 21.0 SEER and a cooling capacity of 9000 Btu/hr.

Milgard Montecito vinyl windows were installed in the master addition to complement the vinyl windows of the existing home. The windows were ordered to comply with federal tax credit energy requirements. The 45 degree angle bay window is 8 foot x 5 foot with a 24” projection and 24” side flanking windows. The sliding patio door is a two paneled 5’11” x 6’ 10” white Andersen maple door with a clear interior finish. The door’s glazing has high performance smart/sun glass, with low E-4 tempered glass and rubbed bronze door hardware. The interior doors are clear Hemlock 4 panel doors with shaker panels. The door hardware chosen was the Ribbon and Reed lever handles from Emtek manufacturing.

To comfortably and economically heat this addition, radiant floor heating was chosen as the heating source. The heated floors were found both in the bathroom under tile and in the bedroom under the oak hardwood flooring. With radiant floor heating different zones can be set up for different rooms. The bathroom and bedroom each have different digital temperature controls so that the rooms can remain at different temperatures. Typically radiant floor heating systems operate either by circulating warm water through a network of pipes placed in the floor or electric resistance wiring placed in the floor. For this project, hundreds of feet of cross linked polyethylene piping was fixed to the subfloor and a thin light weight concrete slab was poured over both the piping and the subfloor. The heat source used to heat the water was the existing boiler for the home. Engineered I joists where used as the floor system, they were filled with blown in fiberglass batts and R-10 rigid board insulation was installed below the I joist system in the crawl space. The homeowner has found that stepping onto heated hardwood or tile floors to be very comfortable.

The Master bedroom suite room addition was approximately 550 square feet. The wall height was determined in order to match up the fascia from the addition and the existing house. The homeowners wanted extra insulation for comfort as well as energy efficiency. Wherever possible the contractor utilized the Blown in Blanket System (BIBS). BIBS is a patented insulation system in which a fibrous netting is tightly stapled to the interior face of the studs and then chopped formaldehyde free fiberglass insulation is blown behind the netting. When correctly installed this process will not settle over time, packs in around wires and other obstructions and has no voids. Additionally, 1 inch rigid R-Max foam was nailed to the interior of the stud covering the BIBS in the exterior walls.
The I joist floor framing (containing the plumbing and Hydronic heat home runs) were also filled with R-38 BIBS which was covered with Gorilla Wrap air barrier paper. R-67 BIBS was used in the vaulted scissor trusses and R-23 was utilized in the 2×6 walls. Where BIBS was not usable, unfaced formaldehyde free R-50 batts were used. The owners are pleased with the resulting comfort and energy efficiency of the room.

This remodel was driven by the need for a handicap accessible master suite. The first option the homeowners explored was to remodel their existing second floor bathroom to make it handicap accessible and to install an elevator or lift to the second floor level. That option was deemed awkward (there just was no good place to install an elevator) and thus was less desirable (from an appearance sake and resale value) than to add a handicap accessible master suite on the first floor. The designer was able to design the new addition so that it actually enhanced the existing structure. A corner cabinet in the existing family room was removed, being replaced by an entry hall into the master bedroom and bathroom suite. In order to accomplish this the hot tub was relocated and the deck reduced slightly to accommodate the room addition. The deck can now be accessed from both the family room and the new bedroom. An entrance and hallway from the garage was constructed so the bedroom can be accessed directly by another entrance. When the need arises, a handicap ramp can be built from the garage into the bedroom.

This picture shows how we’ve married in the metal framing to the wood framing. The steel tracks attach to the wood trusses overhead and is screwed to the wood subfloor below. Note in the middle of the picture that we’ve got wood nestled into the steel stud in order to provide rigidity and nailing or screwing capability for a door opening.
