Erbar Mattes is a London-based architecture practice founded by Demian Erbar and Holger Mattes in 2015.

We are dedicated to creating elegant projects that are firmly rooted in context, aiming to enhance and rebalance the essential qualities of a place, shaping purpose- and characterful buildings that are unique and truly belong.

Erbar Mattes has gained a reputation for its multi-faceted, sensitive and carefully crafted work and been recognised through international publications and awards.

We are delighted that our practice is the Architect of the Year winner at the British Homes Awards 2023. Our retrofit of a listed former East-London pub, Blockmakers Arms, won the Home Transformation of the Year prize at the British Homes Awards 2023, a 2023 RIBA London Award and is a Gold winner at the international Erich Mendelsohn Awards for Brick Architecture. It is also one of twenty houses on the longlist for the RIBA House of the Year 2023. In 2022 Erbar Mattes was one of ten Architectural Record New York Design Vanguard winners, selected from emerging talent around the world.

We are passionate about creating more truly affordable homes in low-carbon / low-energy design and are actively exploring new materials and methods of construction. An innovative timber frame house with ground source heat pump and heat recovery ventilation system has recently achieved practical completion in Wimbledon.

Our collaborative approach to delivering high-quality results and exceptional value has helped us build lasting client relationships.

Services

Our practice follows a well-structured process based on the Royal Institute of British Architects' Plan of Work for UK projects. We provide a responsive, friendly and personal architectural service from concept to completion, competitively priced and with a focus on cost-effectiveness. show more

Erbar Mattes works across a wide range of scales and budgets and offers prospective clients a free initial consultation to understand their challenges and needs.

Over the years we have gained extensive knowledge obtaining planning approval within conservation areas and for listed buildings in England. Our practice has developed a restrained and sympathetic architectural language that mediates between modern and historic contexts, successfully addressing these particular planning challenges.

All projects are developed with 3D Building Information Modeling software (BIM) to create a digitial twin of the building, allowing us to share virtual walk-through models, explore options, resolve complex spatial questions, and produce well-coordinated construction information.

We collaborate with a network of experienced consultants for planning and construction reports. This allows us to provide early guidance to our clients on the necessary requirements, enabling them to budget effectively.

With our international background and project experience, we have established connections with excellent architects from around the world who can support us in delivering designs overseas. Our network extends to countries such as Germany, France, Spain, Switzerland, the Netherlands, Argentina, Mexico, and the United States. We are fluent in English, German, Spanish and Italian.

Team

Erbar Mattes' co-founders, architects Demian Erbar and Holger Mattes, are passionately involved in shaping and managing all projects from concept to completion. Together they bring 40 years of experience in leading the design and construction of highly acclaimed buildings in the United Kingdom and abroad. These include a hotel for the Capella Hotel Group and Hermès, the purpose-built public art galleries The Hepworth Wakefield in Yorkshire and Turner Contemporary in Margate, and the housing-led regeneration projects Agar Grove in Camden and Brentford Lock West II in Hounslow, which have been exceptionally transformative for their communities.

What our clients say

Blockmakers Arms
 
Erbar Mattes took us from that instinct through to a concept design and then supported the delivery of every detail. ... We love this house as it functions and looks now.

Noblefield Heights
 
Erbar Mattes carried out this brief with great precision and very thorough drawings. They went beyond our expectations by having the vision to recreate our living room area and kitchen into a beautiful bright space that has been the centrepiece of our home and a joy to be in.

Plykea
 
We’ve lost count of how many times customers say "oh wow, you actually make it here!?" and have a walk around and say "hi" to the team and see things in motion. ... Our goal, which Erbar Mattes has successfully delivered, is for the whole space to function as one big showroom rather than its component parts.

Hill House
 
And thanks for all you have done to get us through the planning hoops again!

Erbar Mattes adds pale brick extension to Edwardian house in north London

A limitless microcosm (TEC21, September 2017)
 
In this seminal house, a whole array of apparently modest but actually very powerful and effective design strategies are at play, at many different levels. Their cumulative “gestalt” impact, although subliminal at first, is felt immediately.
