Light, spacious homes for family life, designed with you since 1995.
Discuss your projectSimon worked as a senior architect for several high-profile London practices before setting up his own practice in 1995, concentrating on residential design in the UK and commercial interior design in Moscow.
We have worked within a 15 mile radius of West London for over two decades, on extensions, loft conversions, refurbishments and new houses. Simon has built up an experienced and talented team, and most of our work comes from past clients' referrals or from other professionals who have worked closely with us over the years.
Simon's clients have included McCann, Novartis and Bank of Tokyo Mitsubishi. The practice has won the Design & Conservation award for Richmond, and designed one of the first integrated roof-light and solar panel schemes for a residential slate roof in the UK.

Featured project
The brief called for a large open-plan kitchen and dining area opening onto the rear terrace and garden, with a study, utility and cloakroom.
The client adores industrial design and wanted the Crittall look for the glazed façade, with industrial style roof lights. The concept was a light and spacious split-level space with maximum views of the garden.

Refurbishment, extension and loft
The client brief called for a large open-plan kitchen/dining area opening onto the rear terrace and garden. Also, a study, utility and cloakroom. The client adores industrial design and wanted the “Crittall” look for the glazed façade and industrial style roof lights. The concept was to produce a light and spacious split-level space with maximum views of the garden.
Extension and refurbishment · Esher
A superb extension and refurbishment of a 1970’s house. The project has transformed a modest house into a truly wonderful home for entertaining and family living. The key was to open up the dark hallway and insert a beautiful galleried stair and landing. We worked closely with Caroline Browne Interior Design to produce an elegant mix of materials, colours and lighting to enhance both the new and extended spaces.
Side extension, loft and refurbishment · Teddington
We designed a new, light, spacious open plan extension for a young family who needed more space for a busy life and entertaining family and friends. The clients had a bold sense of colour and great feel for the interior. The result is a superb family house.
Extension and refurbishment · Teddington
A beautiful extension and refurbishment in Teddington. A previously extended Edwardian house needed a new extension to suit a growing family. We stripped out the ground floor kitchen and utility spaces and designed a new, light, spacious open plan extension ideally suited for family life and entertaining.
Two storey side and rear extensions · Teddington
A tired Edwardian house needed a fabulous new extension and full refurbishment for a busy family. We designed a new, light, spacious open plan extension ideally suited for family life and entertaining. We designed 2 storey side and rear extensions to transform the whole house.
New annex and refurbishment · Teddington
New annex for Teddington house. Achieving the impossible, planning consent for a new annex extension was won to complement this elegant Victorian house. Full refurbishment and the addition of new garden facing open plan living areas and a master suite complete the transformation.
Orangery and basement · Barnes
A new orangery dining space provides a delicate and airy transition between the island kitchen and the walled garden.The basement extension connects the main house with the garden building.
Rear extension · Ealing
An Edwardian detached family house. The brief called for a new connection to the garden which should be stylish and elegant. We relocated the utility and den in the middle of the plan to allow a near full width Kitchen, dining and living space for family and entertaining. Crittall styled doors and windows compliment the stock brick extension.
Loft extension · Twickenham
We were asked to design a spacious, light loft extension to a newly acquired Edwardian semi- detached family home. The brief called for a natural flow from the first floor to the new loft. The client wanted us to incorporate exciting ideas for colours and tiling to the bedroom, study and bathroom.
Extension, loft and refurbishment · Kew
A very interesting brief required us to design an extension to link the house with the garden. The extension has a split-level study above the kitchen with a ‘secret stair’ for access. The loft was converted to provide a whole new floor for a further 2 bedrooms and bathroom.
Rear extension · Teddington
This mid terraced property had a poor connection with its unusually shaped and sunken garden. Our response introduced steps down to an open plan living space with a cranked plan to promote the connection with the garden.This dealt with the restricted site and the introduction of the large long roof light meant the rear of the house was filled with light.
Kitchen and orangery · Thames Ditton
This detached house had an undersized, small and dark kitchen with no connection to the dining space or garden. A few smart structural changes completely transformed the space available and created a connection to a newly refurbished light and bright orangery beyond.
Vaulted extension and refurbishment
Our client had lived in their home for 15 years saving, planning and dreaming of one day having their dream home. We designed a new, light, spacious open plan, vaulted extension for entertaining family and friends. The clients were thrilled and have since completed the garden to complete the dream.
Loft conversion · Teddington
An interesting project to utilise an existing large loft space. The client had exceptional taste and chose beautiful internal decorations, fixtures and fittings.
New house and interior
The brief was to demolish an ordinary awkward house on a beautiful plot and design a new house based on rays of light permeating a simple house plan. We were helped by a very daring and enthusiastic client!
Extension and refurbishment · Teddington
A very interesting project for a terraced house with an unusual existing plan. The kitchen projected into the garden, splitting the outside space into two halves. Internally the space did not flow and we therefore created an light-filled and extended living space to accommodate the young family and their books.
Extension, refurbishment and interior
We transformed an ordinary 1960’s bungalow into the ultimate Bachelor pad. We redesigned a substantial proportion of a poorly constructed house and turned it into a cool and relaxing modern home.
End of terrace extension and refurbishment
A very interesting project on an end of terrace house incorporating the old village post office. The kitchen had no visual connection to the garden and was on a lower level, making it dark and unwelcoming. Internally the space did not flow and we therefore created an extended living space with a light, modern atmosphere and unimpeded views of the garden.
Rear and side extension · Surbiton
Our client had ambitious ideas for this semi-detached house. We wanted to create modern, light spaces for the kitchen, dining and living areas focussed on the rear garden.
Extension and re-design · West London
We re-visited this project after completing the upper floors and added an extension and remodelled the space to create an open plan living area which re-balances the proportion of bedrooms to living areas.
Rear extension and loft conversion · Teddington
This was a 2 phase project to completely refurbish and extend the loft and ground floor and transform the house into a bright and remodelled house suitable for entertaining and family living.
Every project is different. These are the stages we take each one through, so your requirements fit your budget from the start.
Stage 1
After an initial consultation we complete a full survey of your home, so our design proposals start from how it really is.
Stage 2
We present our proposals in full 3D. You can walk through the new space and get a real feel for how it will look once completed.
Stage 3
Once planning is achieved, we tender the project to a minimum of three contractors, review the tenders with you, and you choose your contractor. Some clients prefer to have their project costed by a qualified Quantity Surveyor first.
This is generally better value than a one stop loft or extension company, who do not tender their work and often quote bare minimum prices, adding the extras at the end.
Stage 4
We administer a JCT contract throughout the build, so objectivity is maintained and the contractor is bound by the terms and budget agreed from the outset.
A full Project Management service is also available, co-ordinating every aspect of the project from start to end.
Our interior design service runs alongside our architectural work. It is about how you experience your spaces, for work or play, and getting them right for you and your family.
