Discuss Your ProjectView Our Work

How we can help

A double storey extension can improve the arrangement of your home across both levels. J.LEO develops the design around your existing rooms, circulation, daylight and the relationship with neighbouring properties.

Choose Planning & Technical, Interior Design or Construction, or bring them together through Design & Build.

Useful to know

Can I appoint you for design only?

Yes. We can agree a design and drawing package separately from construction. Tell us the stage your project has reached and the support you need.

Can you work with drawings I already have?

We can review existing drawings and identify any further information needed before agreeing our scope.

Is interior design support included?

When J.LEO is appointed for construction, interior design support is included within the agreed scope. Products, purchases and additional services are agreed separately.

How are fees and costs agreed?

We review your brief, property and required deliverables before providing a project-specific proposal. Design fees, construction costs and specialist appointments are clarified in writing.
