61,610 Design and Build Companies

Planning a renovation project or building your own home can mean involving a lot of different companies, contractors and professionals, making everything a bit of a struggle to stay on top of. One way to cut out a couple of middlemen is to use design and build contractors to build and design a house or a few rooms; handling your project from design and planning right through to construction. Hiring a design and build firm will make it so much easier if you plan to build your own house from scratch as they can work with you through every step of the process, without having to switch from architect, to designer, to builder, to stylist and back again. Design and build contracts have become more and more common as homeowners look to find more efficient ways of building custom homes, and you can find a whole list of design and build contractors right here on Houzz if you’d like to find out more about hiring a design and build company.

What is design and build?


A design and build company does pretty much what it says on the tin – designs and builds your home; helping you design your own house from scratch, pick out the small details and actually bring your dream home to life. They will take on the responsibility of planning the project, drawing up the designs, costing, sourcing the building materials and supplies, building the structure, installing any permanent features and possibly advising on the interior design of your home; all while consulting you every step of the way. A design and build company will usually employ in-house architects to handle all of the technical design aspects of your renovation or build, whether that’s to design a house or just a kitchen, and will also have main contractors or project managers that will oversee the construction work. The project managers will either work with external building contractors or construction companies, or the design and build company may employ their own builders to carry out the construction work. Either way, all the work is managed by one company and so this means communication is easier and the work is more streamlined. You’ll probably have just one design and build contract, making responsibility simpler and clearer, and also reducing costs for you. However, you should always check this design and build contract closely to see exactly what the firm is agreeing to take responsibility for, so that you don’t get left in the cold at any point.

You don’t have to build your own home to hire a design and build firm. If you are renovating one or a few rooms of a house, a design and build company can still help you – they can design a kitchen, bathroom, bedroom or living room and then complete all of the renovation work for you. This could be a really good option if you are selling your home and want to increase its value quickly – hire a design and build firm to redesign and renovate a few rooms of your house without the hassle of dealing with various professionals or the time-consuming effort of doing it yourself.

If all of this sounds ideal, then start searching for design and build procurement companies that can design a house, or room, for you and discuss design and build contracts with you. If you want to look for more specialised contractors, designers, architects or builders to help you renovate or build your own home, then you can still find them on Houzz. Here are some related professionals and vendors to complement the work of design & build: Interior Designers & Decorators, Landscape Architects & Garden Designers, Architects & Building Designers, Photographers.

Questions to ask a design and build company:


  • How long have you been an established design and build company?
  • How does your business work? Do you have architects, designers and builders in-house or are you a project management company?
  • Will you help me to build my own house?
  • Will you handle the interior design of my home as well?
  • What will a design and build contract involve? Do you use a Joint Contracts Tribunal (JCT) approved contract?
  • Have you worked on similar projects to mine before?
  • How long do you estimate each part of the process to take? Will the design aspect overlap with the construction?
  • Can you give me a written estimate for the whole project?
  • What happens if the final cost exceeds my budget?
  • Who should be my main point of contact throughout the project?
