Single & Double Storey Extension in MORTLAKE

Single Storey Extension

side extension london

Single storey extensions, most often extend from the rear, side or wraparound (side & rear). They are a great way of gaining more space for the family, & work well with connecting the living room to an extended kitchen with bright airy window panneled doors that lead out towards the garden. These projects have become increasingly popular.

Double Storey Extension

The Double storey extension option is the most effective project per square foot you can undertake. These builds give you more bang for your buck than a single storey extension. You are also free to transform the look and feel of both upstairs and down. We have noticed many small and growing families approach APT to carry out this build.

Types of architecture services that APT provide



Our house remodelling service involves working with you on architectural drawings that change the structure most commonly within the existing build print of the house. An example of this can mean converting a single storey house into two or more storeys another example can be the internal restucturing or the relocation / removal of walls.

London Residential Construction Architects

Experienced Architects in Mortlake and West London.

As one of the leading residential architects in South West London, we have worked on a wide variety of residential housing projects across the county and and are always excited to be invited to design new homes. Our excellent relationships with the local planning authorities, together with our solid knowledge of local planning and building regulations, has gained us an outstanding reputation for obtaining planning permissions for new build houses. Our team consists of only the best London residential architects.

No project is too large or too unusual for our residential architects to consider:

Whether your project involves a build work to occur on two or more floor levels; or a single level, our team of talented ARB / RIBA architectual designers and technicians will committedly embrace the challenge of taking your plot and creatively working with you, whether you have past drawings or not, to provide plans that can be built fast and cost effectively.

Benefit from a collaborative strong workforce and never be more than a call away from our architectural design & project management teams.

We know that the success of your project depends on the quality of our relationship with you as much as the quality of our design and buildwork expertise. Consequently, it is very important to us that we allocate time to understand your ideas and plans, which is why our first step in the planning process is to have an initial site visit & discussion with you.

This could involve discussing whether your garden is big enough to accommodate the extension building or exploring how to release the greatest investment potential out of a plot of land bought for financial return. You can also develop the plot to maximise the beauty and functionality of the residence to see you through the future stages of your life.

We believe your new home should reflect your own personality and individual needs,

We are expert in drawing up plans for bespoke homes that are mindful of this. Conscious that circumstances can change, if and when appropriate, our architects will invite you to explore beyond your immediate requirements and highlight ways that you can save money, remodel and adapt your living space to your requirements.

We always aim to add value through good design and planning.

Our practice does not support a particular ‘house style’ and our portfolio contains properties that reflect many architectural styles. This means that we have experience of a variety of different designs to be able to suit a majority of tastes. Appreciation of design is very subjective; it may be that you like modern contemporary design with a minimalist open airy feel; or love the look of the informal New England style houses or are after a neo classical frontage. You may wish to see several different styles reflected in the overall design. Our contemporary residential architects in London can help you today!

Maximising investment return.

Like all the best residential London architects, we know that good design will add considerable value to your end project and it is important to us that your finished home will not only be warm and welcoming, something to be proud of and somewhere you wish to be, but an asset too. We will also be checking that as far as is reasonably possible the proposed building will sit well on the plot in terms of aspect, taking advantage of natural lighting, accessibility from the road, and that it will reflect the heritage of the local area so to optimise your investment return should you choose to sell.

Our investment in up to the minute design software makes committing to a new build project less daunting.

By taking advantage of the latest technology you can make informed decisions right from the start. As standard practice we include 3D sketches of your new house design with your plans to help you visualise the project. Should you require, we can also carry out an initial project feasibility study, or you may commission 3D Modelling and Visualisation of the proposed design, this will fill out the finer details including proposed materials and interior design. Any of these options will help you determine the viability of your project, fine tune the design and give you the reassurance you need to proceed with confidence before making a further significant financial commitment.

Commercial residential new housing.

Our team of commercial architects is experienced in all aspects of commercial residential design and pays particular attention to the “sellable” features”, floor areas, and layouts to maximise the efficiency of a layout and allow a profitable development return for our commercial clients. We have experience with both large and small developments: it may be that you wish to turn a large house into a block of flats to take advantage of the rental market; or have purchased block of land with the intention of building a mixture of residential new housing.

Whether it is a single dwelling that is required, or multiple housing, we can meet your needs, either by design only, or construction working drawings on a Design Build project. We also carry out initial site feasibility studies to ascertain the viability of a site before purchase and give you that reassurance you need to invest in your scheme and to proceed with confidence.

Paying attention to costs…

We know that the best London residential architects need to take affordability into account for their clients, managing costs is always a consideration regardless of the size of budget available. We will, as far as is reasonably possible, do our best to deliver your project on time and on budget. Of course, the size of budget you choose to invest in your project is your decision, but it is important to us that your money is spent wisely and that you are investing in a building project that, even if the desire is not to sell, is best placed to realise a good return on your capital investment. We will be looking to point out the break point where we believe investment in the project will incur more costs than the plot will return so that you can make informed choices.

Looking after the environment…

As commercial architects the practice has always been committed to protecting the environment and we work closely with sustainable energy consultants in the design of developments to reduce the carbon footprints of new buildings by utilising renewable energies and efficient construction design. The deployment of innovative sustainable practices and materials ensures our buildings are warm and energy efficient as well as healthy to live in.
