Projects

Services

Concept

Briefing & Survey

Armstrong Simmonds Architects will work with you to develop a concept design, sketching layout options to explore the potential of the property. We will also carry out a full measured survey of the property and its surroundings, allowing us to produce an accurate set of drawings.

Planning

Application & Scheme Design

Following on from the briefing we will prepare a set of scale drawings reflecting the range of ideas discussed. We will prepare and submit the planning application, liaising with the council as needed throughout the process. Our extensive experience will help facilitate a smooth planning process.

Visualisation

3D Modelling Services

To help you visualise the space in three dimensions we can produce internal and / or external views of your project. This can also be a useful tool to demonstrate the merits of the scheme to planners.

Technical

Building Control and Detailing

We will produce detailed technical drawings including drainage and electrical layouts, consulting with you to ensure the design meets your needs. We will then submit to building control and manage the approval process. As part of our architectural services during this process we can assist you in appointing other consultants, for example the structural engineer or party wall surveyor.

Specification

Interior Architecture and Schedules

We offer interior architecture and design for a high spec finish. We can produce further detailed information integrating specialist glazing components, floor finishes, joinery and bespoke staircase design as required.

Interior Design

Furniture, Fittings & Equipment

We provide Interior design architecture services ourselves or through collaboration with other London based Interior Designers, who may also be appointed by the client.
We are happy to specify FF&E (furniture, fittings and equipment) for the project, providing a complete “one-stop” shop for your development.

Tendering

Prices and Builders

We will help you make an informed choice on an appropriate contractor. We maintain a selective tender list of contractors especially in the local London area, who we have experience working with on site. We will prepare tender documentation and appraise their quotes.

On Site

Contract Administration

Armstrong Simmonds Architects facilitates the implementation of the design by administrating a contract between you and the contractor. Amongst a wide array of architectural services, this will include undertaking site visits to monitor the quality of construction and handle any on-site queries from the contractor.

Michael van Ree

John and his team have been brilliant to work with for our full house renovation and extension in SW London. Our house is quite unique and that combined with it being in a conservation area we knew it wouldn't be a straight forward planning process - but Armstrong Simmonds did a fantastic job and helped us navigate us through every step. We couldn't be happier with the detailed design and outcome.

Linda Roberts

Architects Armstrong Simmonds were appointed by us to turn our concept of open plan living into reality, which they did with extraordinary vision and design flair. The AS team listened carefully to our ideas and transformed an ordinary detached house into a breathtakingly beautiful home that offered light, space and a lifestyle that exactly reflected our needs and requirements. AS worked closely with us and our builder, and their focus to detail in the design and build was impressive. This young architectural practice in our opinion, offers something more. They listen, understand and are unique in their ability to conceptualise, plan and build with imagination, whilst considering aesthetics and functionality. Linda and Allan Roberts ...>>

I cannot recommend Armstrong and Simmonds architects highly enough. Within minutes of John meeting us at our home he had understood our brief and was sharing a vision that ticked all of our boxes. We had met with other architects who did not inspire us and told us the shape we wanted for our extension would not be possible. John had excellent knowledge of the local planning rules, researched planning submissions in the immediate area and was confident that he would get our application through - and he did! During the detailed design process John and his team listened closely to how we wanted to use the space. He came up with many design features and solutions to save costs and keep our dream design within our budget. Throughout the process they delivered an innovative plan that felt personal to us in a professional and timely manner. We found John and his team to be responsive, helpful and caring. They went above and beyond to get our project over the line and I have no hesitation in recommending the firm to anyone looking at home extension/improvement. We would not look anywhere else for any future builds! ...>>

We had a fantastic experience with John and the team at Armstrong Simmonds. We have a beautiful home and would happily use them for our next project.... hopefully even bigger next time! Flawless from beginning to end, I thoroughly recommend them.

By implementing our technical expertise, our architecture studio solves design problems creatively to provide a space which is both functional and unique.

How We Transform Your Ideas Into Reality

Our architects studio will carry out a detailed survey of your property from which we can produce a comprehensive set of existing drawings. In close collaboration with our clients, we then develop the initial concept designs. This process is iterative and multiple ideas will emerge. We also use digital 3D models to assist our clients’ visual understanding and enhance the design process. Once the client is satisfied with the proposals and we have submitted the planning drawings, the next step involves producing a highly detailed set of technical drawings through coordination with a structural engineer and other relevant design specialists. We also provide tendering and on-site services to ensure the plans are converted into reality. Communication is an important part of our process as an architecture firm. We will guide you along, each step of the way, to deliver your dream home.

Transforming Visions into Reality: Unique Architecture from the Studio of Armstrong Simmonds Architects

At Armstrong Simmonds Architects, we have a wealth of experience working on residential projects of varying sizes with challenging planning and on-site conditions. Our experienced team at our architectural firm will work closely with you from concept design to completion to ensure your project aspirations are met. As an architect studio London, we look to deliver high end design outcomes, whether they are modern or traditional, with a deep consideration for aesthetics and functionality. We aim to do more than extend the footprint of your property by implementing creative design solutions which modernise the fabric, interior architecture, and performance of your home. Each client is different and has varying design aspirations; we will aim to develop a design solution tailored to your specific style. Whether you are looking to upgrade your property to a contemporary style or create a modern blend which complements the historic architecture, our architects studio will work closely with you to achieve this.

Most of our projects deliver bespoke architectural features which have been carefully designed to fit uniquely into your home. These items typically include bespoke glazing, joinery, staircases, lighting, landscaping and much more. We put particular emphasis on glazing; at Armstrong Simmonds Architects, the design expertise of our architect studio allows us to identify how best to incorporate glazing elements into your project to transform what are often dark existing properties. Maximising the presence of sunlight can help to keep your home warm and in turn minimise your energy consumption. These glazing elements are designed in collaboration with glazing specialists to suit design needs.

If you are looking for design inspiration, look no further! Our architecture firm has worked on a variety of projects within London and can guide you through the design process. This process is not only about getting approval for your planning submission, but also making sure we work together to achieve your vision. We do this by working with you to understand your design sensibilities from the outset, then we take you along the concept development journey; sharing updates about the design brought to life using 3D imagery. If you do not have a particular vision in mind, our team can assist you with that during the briefing process. We can provide interior design services or collaborate with an interior designer to achieve the outcomes you desire. This sets the stage for transforming your dream home into reality.
