Wunderhaus

What Wunderhaus does

Wunderhaus Ltd is a UK-based private company (registered in Battle, East Sussex; company number 11265063) founded in 2018 by architect Nico Rensch and product designer Russell Clark. The company has developed a configurable, energy-positive and carbon-negative housing platform built on Structural Insulated Panels (SIPs) using a Component System Construction approach — factory-precision-engineered panels assembled on site to deliver certainty of quality, duration and cost. The integrated house combines SIP envelope with a 31.68kW solar roof, 34.8kW battery storage, 22kW EV charger, 96%-efficient MVHR system, infrared underfloor heating, triple glazing, thermal storage for domestic hot water, comfort cooling, and graphene-infused air-purifying paint. Wunderhaus generates twice as much energy as it consumes, achieving EPC ratings of A120+ Energy and A105+ Environmental, and saving 4,425 kg of CO2 per house annually.

The portfolio comprises the core Wunderhaus WH series (WH1, WH2, WH3 and their WM2/WM3/WM4/WM5 extensions) covering 2-8 bedroom configurations from 87-300 m2, and the newer Wunderhaus A affordable sub-brand (A1/AM1, AM2, A2) for housing associations, ranging from 64-128 m2. Wunderhaus monetises via a one-time platform fee fixed at 10% of baseline construction cost (or a tiered equivalent of £20K-£65K per unit) covering architectural, structural, regulatory, mechanical, energy-performance, procurement and delivery information. Distribution is direct to enterprise developers, individual self-builders and housing associations, with sales-led engagement, show-home appointments, and a sales-led/enterprise field-sales GTM. The company has secured Red Dot Design Award (2022), European Product Design Award (2023) and London Design Awards Silver (2023), with 2026 shortlistings at UNZA and Green Energy Awards; it is accepted by all major UK mortgage lenders and compliant with NHBC and LABC. Operating status is active, with one completed unit (East Sussex, Q1 2026), a 31-unit Essex development in pre-planning, and a 27-unit mixed-tenure development in the pipeline.
