About Megaplan
Architecture as a Force for Good
We provide advanced architectural and construction design technologies that go beyond current standards in the AEC industry — combining CAD, BIM, and deep regulatory expertise to deliver projects that are sustainable, compliant, and future-ready.
Our Mission
Architecture is our passion. A simple but powerful belief drives us: architecture should elevate life in all its forms.
Our mission is to harness knowledge, creativity, and advanced computational tools to design environments that are sustainable, inclusive, and deeply connected to the natural systems that support them.
We recognise that every structure exists within a wider ecological network. By understanding the delicate balance among all living organisms, we create architecture that enriches its surroundings, strengthens environmental resilience, and contributes positively to the shared world we inhabit.
Our commitment is to design with intention, build with responsibility, and innovate with purpose — ensuring that the spaces we create serve not only people, but the broader community of life that depends on them.
The Practice
Principal
Mike Bustos
Mike Bustos is the founder and Principal designer of Megaplan. With over two decades of experience delivering residential and commercial projects across London and internationally, Mike brings a hands-on, client-first approach to every commission — from initial feasibility through to completion on site.
Mike has guided hundreds of homeowners through the planning process, securing approvals for rear extensions, loft conversions, side returns, and basement projects across London boroughs including Lambeth, Southwark, Lewisham, Wandsworth, Hackney, and Islington. His track record of first-time planning approvals is reflected in Megaplan's 5-star Google rating.
Clients consistently highlight Mike's responsiveness, technical rigour, and ability to manage the full process — from pre-application discussions with councils to party wall agreements, building control sign-off, and contractor coordination. He is fully insured for professional indemnity and public liability.

Our Vision
We believe the built environment has a responsibility to the world it occupies. Every project — however modest — is an opportunity to improve a street, a neighbourhood, a life.
Megaplan was founded on the conviction that rigorous design thinking and deep regulatory knowledge are not in tension — they are complementary. The best outcomes come from practices that understand both.
With more than a decade of practice behind us, we continue to invest in the tools, knowledge, and relationships that allow us to deliver exceptional work for every client, on every project.
Why Megaplan
We are a small practice by design. Every project is led personally by Mike Bustos, with no handoff to junior staff. Clients get direct access to the person responsible for their project from first call to final sign-off.
Our work spans residential extensions and loft conversions through to commercial fit-outs, conservation area projects, and international commissions. The common thread is a commitment to quality, clarity, and accountability.
We are based in London and work primarily across South East England, with selected international projects where the brief and the relationship are right.
What We Stand For
01
Rigour
We do not cut corners. Every drawing, every submission, every site visit is approached with the same standard of care — because the details are where projects succeed or fail.
02
Accountability
One point of contact. One person responsible. We believe clients deserve to know exactly who is looking after their project — and to be able to reach them directly.
03
Clarity
Architecture can be opaque. We work hard to make the process transparent — explaining decisions, managing expectations, and keeping clients informed at every stage.
04
Ambition
We bring genuine design ambition to every commission, regardless of scale. A well-considered rear extension deserves the same quality of thought as a larger project.
