A Stress-Free Approach to Property Extensions
Extending your home should feel exciting, not stressful. Our approach is designed to remove uncertainty from the outset, giving you clear guidance and confidence at every stage.
​
We take the time to understand how you want your home to work, then develop practical, well-considered designs tailored to your space, lifestyle, and budget. From surveys and design through to council liaison, we manage the detail so you don’t have to.
​
Planning permission is often the biggest concern, which is why we provide full planning application support and, for eligible projects, the added reassurance of our Planning Permission Guarantee helping you move forward with peace of mind.
We provide planning and design services for a wide range of extensions, including Single-storey extensions, Double-storey extensions, Wraparound extensions and Garage conversions and extensions.
​
Our service includes measured surveys, tailored design proposals, and full planning application support, giving your project the best possible start.
Single Storey Extension
From £795
​
A Single Storey Rear, Side or Front Extension is one of the options that can be considered when you require more space in your home. It can also add value to your property.
We are experienced in knowing what proposals are likely to be granted, saving you both time and unnecessary planning costs. Whether you are unsure or know exactly what you want, we will look at all of your requirements and help advise you to get the right design from the very start.
Double Storey Extension
From £1095
​
A Double Storey Rear, Side or Front Extension can transform the space available throughout your home. It can provide you with the additional bedroom space as well as living, dining and/or kitchen space.
It can be challenging to get the whole design to flow right with your home but we have the experience to ensure you get the most out of your new extension whilst considering all of your requirements.
Property Extension Planning & Design Services
Garage Conversion
From £695
​
Similar to a loft conversion, converting your garage can be an easy way to obtain extra habitable space in your home. Old garages are not typically used as a place to store cars anymore and can end up being used as a place of storage.
If you are after that extra bit of space and don’t want to spend large amounts of money on an extension, why not utilise your garage space?
Wrap Around Extension
From £995
​
A Wrap Around Extension can transform the space available within your home. It can often expand and/or open up living, dining and kitchen spaces, which will change the way you use your space. We understand that the right design is key with a wrap around extension whilst considering all of your requirements.
3D Visualisations
See Your Extension Before It’s Built
Understanding how your extension will look and feel is key to making confident decisions. As part of our planning and design process, we offer 3D visualisations that allow you to explore layouts, proportions, and how the new space will connect with your existing home before anything is submitted or built.
​
Being able to see your extension in advance helps remove uncertainty, refine ideas early, and ensures the design truly works for your day-to-day life. It also reduces the risk of costly changes later, giving you greater confidence as your project moves forward.
Planning Permission Guarantee
Planning permission is often the biggest concern when extending a property. We manage the planning process from start to finish, liaising with local authorities and responding to feedback where required.
​
Our designs are shaped by experience and a strong understanding of local planning policies across South-East London, Kent, and Surrey, helping to maximise the chances of approval.
For added reassurance, eligible projects can benefit from our Planning Permission Guarantee, with full details available in our downloadable guide.
