Designing Your Home

“We listen to our clients to identify their vision and needs. We design
and provide solutions to align with their brief. And we deliver.”

Jo Cowen Architects is a RIBA chartered practice with a highly renowned reputation for delivering striking and meticulous homes. We carefully listen to our clients needs and aspirations- the focus and drive for each of our projects.

Since our inception, the practice has built upon its wealth of experience in the prime residential market, bringing a personal touch and pursuit of the highest quality to every project.

The award-winning studio specialises in bespoke design, offering complete architectural and interiors service from inception, concept design, statutory approvals, technical design, contract procurement, to contract administration on site.

Our in depth understanding and expertise in local planning policies and different building typologies allows us to develop schemes that creatively add the highest value for our clients.

Project briefs are developed closely with the client to ensure the maximum potential of individual schemes can be achieved. We listen very carefully to our clients requirements and their budget, and tailor our projects to suit.

Our extensive consultant and contractor base allows us to carefully build the right project team to every project.

The practice has a diverse portfolio of successfully completed houses (ranging in scale, scope and complexity) on a variety of building typologies throughout London and the South East. These range from the sensitive restoration of Listed Buildings to innovative and highly sustainable new build homes.

We have an exceptionally talented, driven, and experienced team who take a hands on approach to every project they deliver. Our people are the key to the success of the practice.

Our philosophy is to deliver bold yet pragmatic projects that are responsive to our specific client’s needs. Scale, materiality, light, flow, craft, beauty, sustainability and functionality are key focal points across every project.

Our Services



It is often difficult to visualise the potential of a project; how best to utilise and maximise space and value, what planning constraints may be encountered, what likely costs are associated.

We offer feasibility studies and early stage sketch schemes to help answer these questions prior to progressing to planning applications and detail design.  Various design layouts are developed based on the clients requirements and potential of the property.  These can be represented in various forms of media, from hand sketches, full CAD drawings, or Computer Generated Imagery and Renders.



Jo Cowen Architects has achieved planning consent on a vast array of projects differing in scale and complexity. We can offer bespoke planning consultancy services for projects within the various London boroughs and beyond. These include Listed Building, Permitted Development, and Full Planning applications.

We will coordinate relevant reports needed depending on the project, design and local authority (including tree surveys, daylight studies, and transport reports). We can compile and submit the application as your agent and run this through to determination.



Following planning approval, Jo Cowen Architects can offer tailor made detail design services to suit the project and clients needs. These include developing construction drawings, specifications, schedules, bespoke architectural details, and full coordination of other consultant information (such as services and structure design).

Budget planning is critical to the success of any project. JCA can offer end to end cost consultancy services, including pre tender estimates, production of Schedule of Works documents, tender appraisals, and on site valuations. We can also offer full landscape and lighting design services.



Jo Cowen Architects understand the complexities involved in coordinating and running a project from inception to completion. We can tailor the support provided for clients by offering full Project Management, including coordinating all consultants, surveys and stages of the project, arranging statutory applications, all the way to coordinating delivery and installation of furniture on site.

As Contract Administrators, Jo Cowen Architects can also advise our clients on different construction contract options depending on project type and scale.
