3 . Color is fundamental in home design—something you’ll always have in every room. A grasp of how to manage color in your spaces is one of the first steps to creating rooms you’ll love to live in. Do you want a room that’s full of life? Professional? Or are you just looking for a place to relax after a long day?     1    , color is the key to making a room feel the way you want it to feel.

Over the years, there have been a number of different techniques to help designers approach this important point.     2    , they can get a little complex. But good news is that there’re really only three kinds of decisions you need to make about color in your home: the small ones, the medium ones, and the large ones.

    3    . They’re the little spots of color like throw pillows, mirrors and baskets that most of us use to add visual interest to our rooms. Less tiring than painting your walls and less expensive than buying a colorful sofa, small color choices bring with them the significant benefit of being easily changeable.

Medium color choices are generally furniture pieces such as sofas, dinner tables or bookshelves.     4    . They require a bigger commitment than smaller ones, and they have a more powerful effect on the feeling of a space.

The large color decisions in your rooms concern the walls, ceilings, and floors. Whether you’re looking at wallpaper or paint, the time, effort and relative expense put into it are significant.     5    .

A．While all of them are useful

B．Whatever you’re looking for

C．If you’re experimenting with a color

D．Small color choices are the ones we’re most familiar with

E．It’s not really a good idea to use too many small color pieces

F．So it pays to be sure, because you want to get it right the first time

G．Color choices in this range are a step up from the small ones in two major ways

4 . Amazing concept images have shown what homes of the future could look like, as preparations are made for the world’s first freefrom 3D-printed property (房产).

Experts will build a house called Curve Appeal, which will be 3D-printed off-site before being put together on-site to create two outside walls, a roof and an inside part. These four main sections will then be joined together.

Although 3D-printed buildings have been made before, this home — to be constructed in Chattanooga, Tennessee, later this year — will be the first of its kind, as it will contain no regular shapes or angles. The house is the creation of the design company WATG, based in London and California. The design for Curve Appeal draws inspiration from the Case Study House program.

The architects leading the program were famed for constantly pushing the limits in terms of minimalist (极简主义) materials, and trying to create open-plan spaces that focused on enhancing (增强) natural light. In a written statement, a spokesman for WATG said, “Employing many of the same modern design principles, Curve Appeal is the next evolutionary step. It’s important that the architecture and the environment work together harmoniously. The chosen site is steps away from the Tennessee River in a beautiful wooded, sunlit area.”

WATG was awarded the first prize in the Freeform Home Design Challenge in 2016 and given prize money of $ 8,000 to make its plans a reality. The competition was aimed at architects, designers, engineers and artists. Participants were challenged to design a 600 to 800sq ft single-family home that rethinks traditional aesthetics (美学), ergonomics, construction, building systems and structure.

Over the last year, WATG’s Chicago office has been developing their design with Branch Technology. This project is currently underway, working towards breaking ground later this year. Once completed, the Curve Appeal home will have open and light-filled inside living spaces.
