home extension planning design and construction

Extensions, annexes & garage conversions

Seeking to make a significant improvement to your home can be exciting but also a little daunting. There’s a lot to get right, from planning requirements and building regulations through to technical considerations in the construction process and of course achieving the right atmosphere and style.

We offer the full range of services you require to get your proposed extension off the ground. We carry out measured building surveys to produce precise scaled plans and we can source all the necessary mapping to make your planning application valid. We can construct highly detailed 3D designs and through V.R we can allow you to experience your project in an unprecedented level of realism and work with us through options to hone the design to perfection.

2D Plans

We produce precise 2D scaled plans which assist in both the planning and construction process. Our planning drawings provide an accurate display of both ours and the clients vision for the planning authorities to assess. The construction drawings we produce provide contractors with all the vital information they require to do their work effectively and price work accurately as well as allowing them to plan their every step based on all the technical information we provide.

3D Schemes:

Part of our design exercise process is to produce multiple varying options for our clients to get a true understanding of what is achievable in their home and give them ideas they might not have thought of initially. These simplified 3D schemes give our clients insight into potential kitchen layouts, furniture layouts as well as architectural features such as roof lanterns and bi-fold doors. The main reason for producing these schemes is to give our clients a better idea of scale and how functional or practical certain design options can be.

3D model of open plan extension design

3D Modelling & Animation

From a detailed survey and accurate 2D diagrams, we can construct 3D models and environments to allow you to experience your home extension project in a more life-like way.We can build simple models of the broad-strokes or we can go into fine detail adding realistic surroundings, interior furnishings and decor. Read more

Whilst many of our plans and drawings are still standard 2D, we are able to provide plans in fully rendered 3D. We can model individual houses, extensions and even the internal fixtures, decor and fittings of a building if you desire.

We can even drop in furniture, beds and kitchen units or custom features like hot tubs to help you understand the proportions of the space.

The hope is that by producing plans in this way you can have the best understanding of what the finished development will look like and you are more likely to be satisfied with the outcome in the long term.

You can see what the light coming into the room would be like, whether the extension would cast a shadow over your garden at certain times of the day or whether there will be enough space within the extension to fit in an important piece of furniture. The applications of 3D plan drawings are endless. All you need to do is ask.

Our V.R design process is an exciting and highly productive part of ensuring a first rate result from a home extension project.
