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 Westminster. 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 Westminster home.
Whether you are reworking a period townhouse or mansion flat, extending a family home or adding a basement, one team looks after your project from first brief to completed home. With 56 conservation areas and a large number of listed buildings, most Westminster projects turn on getting heritage consent right from the start. You can read more about what we do on our services page.
Westminster has 56 conservation areas, designated by the City Council for their special architectural and historic interest, and the borough includes many listed buildings. In a conservation area you need planning permission for demolition and for some alterations or extensions that would not need permission elsewhere, and some conservation areas have Article 4 directions that remove permitted development rights. 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 Westminster. Every project begins with a free 30-minute consultation.
It depends on the house and the street. Westminster has 56 conservation areas and the borough includes many listed buildings, both of which remove or restrict some permitted development rights; some conservation areas also have Article 4 directions. 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.
Works that affect the special interest of a listed building need listed building consent, separate from planning permission, and applications affecting heritage assets need a heritage statement. We prepare the supporting statements and manage both applications on your behalf.
