Residential Architects IN Lower Morden

Welcome to Armstrong Simmonds Architects

Based in South West London, we are an award winning architectural practice, priding ourselves on our creativity and passion to tailor and deliver bespoke architectural solutions for our clients.

We are a RIBA Chartered Architects practice founded in 2010. Our team has a high level of experience in the residential sector, working on a wide range of projects including high-end residential, new build apartments, house design, basements, extensions & loft conversions.

From our base in Battersea we take on projects within London and have good relationships with Lower Morden’s local planning authority, Wandsworth Council.

We will diligently guide you through each stage of the process from conceptual design / planning approval through to the completion of your dream project in Lower Morden.



Latest Projects


Side & Rear Extension – Twickenham

The clients for this modern rear and side extension were looking to expand their three-bed house, creating a large open plan kitchen and living space while updating the facade of the existing house.

Apartment Battersea

A clean modern aesthetic, brought to life with flashes of colour and vibrant furniture, was the driving force behind this design. Polished concrete floors and exposed brickwork combined with timber and Carerra marble form the stripped back material palette of the new open plan space.

Extension & Refurbishment – Streatham

This semi-detached house in Streatham benefited from a sizeable distance from the boundary, allowing for a generously proportioned side infill extension with a dramatic up and over glazing feature.

Extension & Refurbishment – Wandsworth

This Victorian terraced house in Wandsworth has been completely refurbished and now includes a ground floor wrap around extension. The aim of this project was to bring a modern vibrant aesthetic to this family home.

Side Return Extension – Clapham

This side return extension features minimal glazing to create a strong visual connection with the garden while bringing natural light into the new kitchen/dining space.

Side Infill Extension – Balham

This contemporary side infill extension, in the heart of Balham, aims to bring as much natural light into the deep plan as possible. Floor to ceiling doors and an almost seamless glass roof make this achievable.

Loft Conversion – Clapham

This loft conversion adds a new master bedroom to a three-bedroom terraced house, using bespoke carpentry to make efficient use of the space available.




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 in Lower Morden 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 Lower Morden’s local planning authority, Wandsworth Council, as needed throughout the process. Our extensive experience will help facilitate a smooth planning process.

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.

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 this service we can assist you in appointing other consultants, for example the structural engineer or party wall surveyor.

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 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.

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. Among a wide array of services, this will include undertaking site visits to monitor the quality of construction and handle any on-site queries from the contractor.
