Business Description

denhof design founded in 2014 is an architectural practice specialising in the design and construction of low energy houses and refurbishments for better comfort and in response to the climate emergency.

Thomas started working in London in 2003 for highly esteemed architectural practices on a number of high-end residential projects. The work on design led residential projects has been complemented with extensive research on low-energy methodology in recent years. The Passivhaus design course was passed in 2014.

Combining a vision for clear design with an extensive technical knowledge of how to realise energy conscious structures is at the heart of what the practice does. Client’s needs and requirements are always the priority of any project the practice is undertaking and services are tailored to a specific client brief.

Denhof Design offers full design services, Passivhaus consultancy, help with planning and site supervision on a flexible basis ensuring budgetary and program expectations will be met.

Denhof Design has dealt with an extensive list of planning applications for small-scale residential projects in Greater London in  recent years with more than 30 application being granted.

Current work includes several low energy housing projects in timber-frame construction as well as a barn renovation project in Nottinghamshire to low energy principles.

Hazlemere house

The Hazlemere house was finished in 2019. It’s a modest three bedroom house for a family of three built on a tricky plot and challenging planning restrictions. The house is completely lifted off the ground supported onto singular steel posts rather than foundation strips. This allows surface water to run freely below the floor slab, keeping soil biology intact while preventing the use of CO2 intense concrete. The house was built in prefabricated timber I-studs fully insulated with cellulose fibres on site. We are currently finalising the process for ‘Low energy Building Standard’ certification.

Barn conversion Loughborough

The barn conversion in Loughborough will serve as a retirement home for a couple currently living next door. Planning restrictions meant that we had to build around a concrete structure from the 1960’s rather than being able to start from scratch. This has resulted in additional cost and complications while the overall building performance is still aiming at a heat demand of 30kWh/m2a. Photovoltaic panels, air source heat pump and MVHR will all be part of the low-enery mix on this project.

Timberfrmae house in Hemel Hempsted

The Hemel Hempsted projct is a modern two-storey timberframe building for a family of three. Thermalbridge-free construction, triple glazed windows, high levels of airtightness as well as MVHR will help to keep the energy costs low on this generous new build.
