Our vision

We create spaces that are better for London, its people – and developers too. Thoughtfully designed, sociable, profitable spaces. Places to live, work, and thrive.

We design homes that become the seedbeds of communities. Homes considered from the inside out, in which the needs of people and their neighbourhoods come first – not the tick-boxes on a planning form.

This is how architecture should be.

Making planning work for London

The housing crisis has its roots in outdated regulations. In minimums treated as maximums. In standards that block innovation and neglect modern needs. The result is a new class of buy-to-let investors. And houses that are built to live off, rather than to live in. 

Reform these attitudes, and you build better buildings. You stop asking, How many units can I fit in without breaking regulations? And you start asking, How can I make this a place where people really want to live?


Nicolas Khalili
Managing Director

Nicolas is HWO’s founder, and our authority on all things planning. A leading voice on London’s housing crisis, he’s designed landmark buildings in the UK, US and Asia. He’s also taught architectural design at Greenwich University. Now, he brings this experience to the negotiating table, working closely with clients to develop profitable, sociable residential schemes that see beyond the blind spots of planning regulation. Nicolas is a regular speaker at the annual HOMES event and a member of its advisory panel. Nicolas is also a guest speaker for the Home Builders Federation and Inside Housing. Nicolas is also registered as a DPLG architect in France.

Rejane Salgado
Design Director

Rejane founded HWO with Nicolas, and leads the design team. She holds a masters in public space from Paris Belleville school. Her past work includes Bordeaux’s Tramline, and the French Embassy in Berlin, both with renowned Elizabeth Portzamparc, as well a rich roster of luxury hotels and spas. These days she focuses on a different kind of luxury: beautifully-finished, efficient, compact housing and inclusive public space. Space that gives Londoners room to breathe in a busy city.

Joao Sa
ARB Associate

Joao joined us in 2014 – from Portugal, by way of Japan. With him, he brought a forensic understanding of housing projects. Experience in everything from Code 4 requirements to Lifetime Homes standards. An ability to coordinate building control, tender and construction packages, and a rare technical proficiency: Joao’s knowledge of Revit is second to none.

Julian Cordoba
ARB Architect & BIM manager

Julian is our BIM expert. He has extensive experience in the UK, having handled large-scale residential projects from first survey to final submission. At HWO, he draws on this comprehensive understanding to turn fledgling ideas into fully-fleshed-out production drawings – all while making sure that the digital side of our projects remains in check, and on track.

Marianna Magklara
ARB Architect MArch MSc

Marianna combines great planning experience with a knowledge of Revit to model the practice’s ideas into complex, 3D designs that are ready for planning submission. Inspiring designs that build trust, and comply with regulation. Marianna is also our team's go-to expert on fit-outs and she often leads the team's production information for all things interiors.

Steven Smith
Architectural Assistant

Steven is meticulous. He understands every stage of the design process, and has a sharp eye for the technical ins and outs. Before joining us, he designed residential complexes, care homes, theatres and museums, seeing each project through from first concept to final tender. Now, he combines this experience with proficiency in Revit and NBScreate, to produce fully-rounded designs with full technical specifications.

Idoia Amoros
Architectural Assistant

Idoia understands fit-out. She’s an expert Revit user with an interest in sustainable construction, as well as prior experience working on listed buildings and high-end refurbishments. At HWO, she uses this to navigate the finer details of interior fit-outs, producing rich, textured, efficient designs – spaces that are made for modern use but respect what’s gone before.
