What's the hallmark of a JAC interior?

As you'll see from our portfolio, we don't have a house style at JAC - every project looks different, because in each case, the designs have emerged from a different set of client needs. What is common to all our work is attention to detail - in the materials and finishes we use, and in the workmanship we insist on from the contractors.

So you're a designer and a project manager. How does that work?

We employ people who do both jobs equally professionally. So the person who designs the scheme also manages the project right through to completion, ensuring that the end-result exactly conforms to the designs and specifications. This means we spend as much of our time on-site as we do in the studio.

How are you able to keep to a fixed price for design and fit-out?

Once you've signed off the space plan and concept design, we build up a detailed cost plan that covers the essentials as well as the desirables. Then, when you've told us which of these elements you'd like us to include, we'll invite three or four contractors (some or all of which you may want to put forward) to tender for the build on a like-for-like basis. The chosen contractor will sign a fixed-price contract before work begins on site.

So the contractor's costs will be fixed before work begins. What about JAC's fee?

Our fee for designing and managing the project is a separate element, fixed at the budget phase. So we have no vested interests in increasing the contractor's budget. Our job is to make sure this budget is not exceeded.

What are the benefits of buying office furniture through JAC?

• Independent advice on the most appropriate furniture from manufacturers all over the world.
• Substantial discounts off list prices, on the strength of the volume of business we do.
• And if we're also designing your interiors, the reassurance that the furniture we propose will complement the design and be fit for purpose. We work with the JAC designer/project manager to give you an integrated service.

We need to be sure there's enough storage in our new interiors.

We understand how important storage is in the workplace. We'll find out what each of your departments needs in terms of storage, and make sure that our space plans include the right amount of storage in the right locations. Then we'll source storage units that work well and look good in your interiors.

Our business is constantly changing. Can we continue to consult you post-completion?

Most of our clients maintain their relationship with us, and call on us when they need to reconfigure a space, buy more furniture or - say five years down the line - when they need to move again or take an extra floor. About 60% of the projects we undertake is repeat business.

Can you assess our prospective offices before we commit to moving?

We'll happily survey any premises you're thinking of moving into before you sign any contracts, and help you assess the suitability of the offices and the extent of any infrastructural improvements that need to be made. Our work at this stage could save you from making a very expensive mistake, or help you negotiate more favourable terms.
