Walthamstow Architects

The Klassnik Corporation are RIBA Chartered Walthamstow Architects with our local studio at 69 Brettenham Road, E17 5AZ. We have worked as architects for a number of London domestic residential clients and undertaken public regeneration projects for Waltham Forest council.


We have also designed a number of luxury residential interior refurbishments, one of which featured on ITV’s Love Your Home and Garden, later in 2018. In addition to the public and domestic residential work within the borough we have undertaken extensions and refurbishments in Muswell Hill, Islington, Lewisham and Greenwich.


Alongside our residential work we have experience in preparing designs and planning applications for commercial change of use applications and have worked alongside Waltham Forest council delivering cultural projects for the public realm, notably the regeneration of the scout hall and local retailers on Wood Street and proposals for a community cycle hub building in Leyton Jubilee Park.


Specialising in projects which require careful or insightful solutions, whether due to a difficult site, complicated variety of uses or simply an ambitious quality of design. We have experience in developing exceptional bespoke residential designs tailored to specific briefs.


As RIBA Chartered Walthamstow architects.  We offer a complete range of services from the RIBA plan of work. Whether commissioning us for the whole project or an individual stage, let us help you make the most of your property. Every project is different and an initial consultation at our studio is free so contact us now to speak to your local Islington architects.
