Practice Profile

Levitate is an award-winning London-based architecture practice. We repair, retrofit and reuse older buildings and design high quality modern architecture.

It is led by Spencer Guy and Tim Sloan and provides Architectural, Conservation Architect and Principal Designer services across the residential, leisure, cultural and heritage sectors from the scale of single spaces to mixed-use neighbourhood masterplans.

We are known as a practice for robust design concepts that use our extensive experience and technical expertise to develop projects that can meet the challenges of the procurement and construction processes.

Our Approach

Inventive common sense is the basis of all of our work. We aim for this to lead to architecture that is contextual, efficient and life enhancing.

Whether it be a brand new apartment complex, the redevelopment of a historic site, a new community swimming pool or a sculptural installation, we start every project from first principles, and invent thoughtful bespoke solutions that make sense and are realisable within the constraints of the brief. Every combination of client, site and brief is different and our work reflects this.

As a project progresses through the design and construction stages our attention to detail is rigorous as we remain focussed on the delivery of the best client outcomes for the project.

Our Services

We are an RIBA Chartered Practice and provide a full range of architectural services. We are normally the Principal Designer for our projects which enables clients to benefit from our considerable co-ordination skills.

We are experts in conservation work and have experience working with all types of historic listed buildings and scheduled ancient monuments, normally within sensitive landscape settings.

As well as architectural services we can provide landscape and engineering consultancy services, with the help of regular collaborators who we consider to be integral to the Levitate team. Increasingly we also provide a construction manager service to ensure our projects are delivered on time and budget to the quality we design.

Our Team

We are a strong team having been working together for over 20 years. Each project will be led by either Spencer or Tim who will work with colleagues who have complimentary specialist Conservation, Technical and Principal Designer skills.
