Residential architects
Harper Latter Architects is a residential architecture practice based in Wimbledon, with 30 years’ experience designing new homes, extensions and refurbishments. We take on projects across London and welcome enquiries from homeowners in Richmond upon Thames. Our architects are fully qualified and accredited with the Architects Registration Board and RIBA. Every project begins with a free 30-minute consultation, and you can ask us for a free site and cost report for your property.

We design new homes, extensions and refurbishments, and our work covers basements, listed buildings and conservation, interior architecture, garden and landscape design, and sustainable design. Much of our completed work is in Wimbledon and South West London, and the same team brings that experience to your Richmond upon Thames home.
Whether you are extending a family home, reworking a period house or reconfiguring the garden level, one team looks after your project from first brief to completed home. Period houses here often sit within one of the borough’s 85 conservation areas, so we shape each design around the council’s conservation area statement from the start. You can read more about what we do on our services page.
Richmond upon Thames has 85 conservation areas, each with its own conservation area statement, and the borough includes many listed buildings. Some properties are affected by Article 4 directions, which remove certain permitted development rights, and in a conservation area, demolition and some alterations need planning permission where they would not elsewhere. We advise you on what applies to your property at the outset and manage the planning application if one is needed.
Every project begins with a free 30-minute consultation, and you can ask us for a free site and cost report for your property.
Our design process runs in eight clear stages, from outline proposal and brief through sketch designs, the planning application, detailed design and tender, to on-site construction support and completion. You choose how involved we are at each stage.

Yes. We are based in Wimbledon and take on residential projects across London, including Richmond upon Thames. Every project begins with a free 30-minute consultation.
It depends on the house and the street. Richmond upon Thames has 85 conservation areas and the borough includes many listed buildings, and some properties have Article 4 directions, all of which remove or restrict permitted development rights. We establish exactly what applies to your property before any design work begins.
Fees depend on the scope of your project and how involved you would like us to be at each stage. Our free site and cost report gives you an indicative construction cost guide, and we set out a clear fee proposal after the initial consultation.
Most householder applications are decided within about eight weeks of validation, although proposals involving listed buildings or conservation areas can take longer. We manage the application on your behalf and keep you informed at each step.
Richmond publishes a conservation area statement for each of its 85 conservation areas, explaining why and when the area was designated, with a short history and a boundary map. The council uses these statements when assessing proposals, so we shape your design around the relevant statement from the start.
