Architecture that unlocks property potential.

Mayorga Chartered Architect (MCA). Architecture and planning for HMO conversions, commercial property and residential projects.

More than drawings.
Clearer development decisions.

Good design begins with understanding what a site can realistically become. We combine architectural thinking, planning knowledge and practical accommodation standards from the outset.

HMO conversions

C3 to C4 and larger HMO proposals, layout optimisation, communal space, planning constraints and licensing-aware design.

Planning strategy

Feasibility, pre-applications, Design & Access Statements, supporting statements and responses to complex planning issues.

Commercial change of use

Adaptation and development of business premises, additional floor space and alternative uses across commercial property.

Technical design

Building Regulations packages, detailed design and coordination with other consultants as a scheme progresses.

From opportunity
to application.

Every site is different. A structured early review gives the design and planning strategy a firmer basis.

01 / Discover

Understand the building, brief, constraints and intended use.

02 / Test

Develop layout options and identify planning or technical risks.

03 / Prepare

Coordinate drawings and documents required for submission.
