A design and build contract is an agreement in which one contractor manages both the design and build of your project.
Instead of hiring a builder and a designer separately, you work with one company responsible for the architectural planning, building regulations, budget management and the build itself.
H & OB Building offers just that: your entire project managed from end to end, so there’s no crossed wires, no separate calls to make, no schedules to align; from the foundations to the finishing coat of paint, we’ve got it covered.
How Does a Design and Build Contract Work?
Under a design and build contract, your chosen building company oversees each stage of your project.
Here is H & OB Building’s approach to the design and build process:
- From Design to Decoration: We collaborate with a team of trusted contractors, including electricians, painters and decorators, equipped to manage every aspect of your project and deliver a flawless finish.
- Architectural Collaboration: We work closely with local architects and monitor architectural drawings to give you confidence that your final build will be completed accurately.
- Dedicated Project Management: You will be in direct communication with your personal contract manager who will oversee your project from start to finish, ensuring the job is done on time, within budget, and to your complete satisfaction.
Why Choose a Design and Build Contract?
Choosing a design and build contract gives you a single point of contact and realistic budget management from day one.
Because the designers and builders collaborate from the start, you avoid unexpected surprises, eliminate communication gaps and benefit from faster delivery times.
In a traditional setup, where the design and build are managed separately, you commission an architect to draw plans, and then put the project out to tender with various builders. If the builders’ estimates come in higher than expected, designs must be redrawn, leading to frustrating delays and extra fees; choosing a design and build contract eliminates this.
