Although winter is certainly here, that doesn’t mean the Boston real estate market has gone completely into hibernation. Luxury condos are still selling.

Two recent spectacular sales include 35 Channel Center St., #509 in the Downtown area and 343 Commercial St., #TH12 on Union Wharf in the North End/Waterfront district.

Both units went for more than $3,000,000.

Unit 509 at 35 Channel Center St. sold on Dec. 30 for $3,100,000.

This amazing penthouse is a spacious 2,742 square feet and includes four bedrooms, two full baths and a half bath.

It can be found on the fifth floor and is described as a “truly one-of- a-kind property, capturing the spirit of Boston in a modern industrial loft in a brick & beam building.”

It looks and feels a lot bigger than it is, thanks to a wonderful open floor plan. The kitchen is a chef’s dream. This magnificently designed complete custom kitchen comes with Sub-Zero and Miele appliances, concrete countertops and a huge island with seating. It is part of a flowing open kitchen-dining room-living room setup that includes arched windows. There is also an office/studio flex space that will make getting work done a relaxing joy. Light just doesn’t come into this home through the many large windows – it also shines in from above through skylights.

Another feature that adds to the feeling of space in this townhouse is the 13-foot wood bean ceilings with recessed lighting and steel accents. There are hardwood floors throughout the unit. The master bedroom has plenty of space to feel comfortable. The new owners will not need to wonder where to fit all their clothes – storage is not a problem with a very sizable master closet. Of course, there is a master bath. Like everything else in this home, a lot of care went into its design with luxury and comfort in mind.

Finding a place to put the vehicles is handled as well with two garage parking spaces.

Spring will be here soon and that means frequent trips to the rooftop to enjoy the incredibly beautiful 1,100-square- foot terrace. This is made for entertaining. On the terrace is a complete Viking kitchenand lounge area that includes a fireplace for those chilly nights. Views from the top are awe-inspiring, especially looking out to the downtown area.

And just because the temperature drops or it rains (or snows) doesn’t mean the fun on the top has to wait. There is a glass-enclosed four-season room with a TV, seating, dining and storage areas. This is one of the most fabulous residential rooftop set-ups in the city. This home was originally built in 1919 and the last renovation is listed as occurring in 2011.

Gibson Sotheby's International Realty is the listing broker for this home.

There is plenty to enjoy around the area, including numerous restaurants and opportunities to shop. The Boston Children’s Museum is nearby and it is not very far to the Boston Common. For driving purposes, the Mass Pike and Rt. 93 are within easy reach.

343 Commercial St., #TH12 on Union Wharf on the Waterfront/North End sold for $3,100,000 on Jan. 17.

Union Wharf is one of the most desirable places to live in Boston. It is a place deep with history with beautiful granite buildings dating back to the 1830s. Originally used as warehouses, these were converted into condominiums in 1978. Union Wharf today offers loft-like, brick-and- beam apartments, beautiful landscaping and a “residential-like” feeling.

Union Wharf encompasses two granite buildings and 23 townhouses. Of the 89 units there, 75 are for residential use and the rest are commercial/residential.

The new owners of this luxury townhouse will enjoy 24-hour concierge, gated parking and on-site maintenance. No need to sweat on hot days since residents get to enjoy the seaside heated swimming pool. And for those who want a boat to enjoy Boston Harbor and the ocean, there are marina slips. There is also guest parking.

One of the great features of the units that make them so appealing is the taste of the past mixed with the modern comforts of today. The exposed brick and beams honor the long history of these buildings. But residents can look back on the past while enjoying the best of up-scale modern appliances and high-end finishes.

Townhouse 12 is a south facing home with 2,292 square feet of living space. It includes three bedrooms, two full baths and a half bath. There is also an additional room on the second floor that is perfect as a study, office or a fourth bedroom overlooking Boston Harbor. A marble foyer is the passage to a beautifully designed open living/dining room with exposed brick and a wood-burning fireplace.

The kitchen offers plenty of space for the chef to create many delightful culinary creations. All the appliances are high end and new. On the second floor are two bedrooms, a full bath and laundry room in addition to the study/office/fourth bedroom.

The top level is where the master suite is found. Helping with lighting are skylights. There is also an en-suite bath with a muscle-relaxing Jacuzzi and steam shower. And the new owners will enjoy the incredible private deck that offers stunning views of Boston Harbor and the city.

There is a common roof deck overlooking the Harbor and the city. It is also a pet-friendly property. And for those occasions when the new owners want to spend more time with their neighbors, they will have fun on the wonderful common roof deck.

The property is beautifully landscaped and includes many picturesque gardens. Another of the great things about living on Union Wharf is its easy access to many interesting places to visit. It is just steps to the Financial District, historic Faneuil Hall and all the fabulous North End restaurants and shops. Public transportation is nearby and sports fans will love being close to the TD Garden.

Union Wharf is also within walking distance of Christopher Columbus Park and the beautiful RoseKennedy Greenway.
