CGI interior images

CGI interior image of a study

These CGI interior images were produced by our studio in 2022. We have researched the latest design trends to create images. The brief was to show off the interior spaces of this design of kit home. External CGI images of the house were also produced.

Eco Homes CGI visualisation

Offplan3d produced this CGI visualisation image for an Eco Homes building developer. The purpose of the image was for estate agent sales and social media promotion. The physical building project had progressed to a stage where either deposits to be taken or ‘off-plan’ sales to be made. This makes sales easier as the customers can see the bricks and mortor that are paying for, even the garden is a sea of mud.

Eco Homes CGI image

The CGI image we produced was 4K ultra high definition, this allowed for use in estate agent printed sales materials.

The client supplied our 3d visualisation studio with plans, elevations and some onsite photographs. Also windows and doors details and finishes were given. Using these references we were able to construct the CAD model, add CGI materials, lighting, props and cameras. The final step was to let the computer produce the final image shown at the top of the page.

This CGI renender image cost around £400 to produce. Click here for more information on our eco homes CGI visualisation prices or ring us for an informal chat about how we can help you on 01237 45 23 23

3d house renders for Planning applications

Planning submission 3d renders in Devon and Cornwall

Offplan3d is a Computer Generated Image business based in the South West of England. We specialise in producing professional quality 3d house renders for planning applications.

CGI 3d architectural models are created from supplied plans and elevations. Using these models we then produce computer generated images, known as 3d renders, of the building project. These images are then submitted with your planning application onto your local authority Planning Portal. From here they can be viewed by the planning department officer, parish council planning committees or the public.

CGI 3d renders have taken over from architects sketches as the best way to showcase your proposed building project. Our studio can use real world lighting and materials in a Computer Generated environment to produce highly accurate photo-real images.

Why use Offplan3d?– We have years of experience sitting on planning committees as well as architectural training and experience. This allows us very useful insider knowledge.

In addition having been shown our competitor quotes by our clients, we know we offer lower prices while maintaining high standards.

We cover all areas of Devon, Cornwall and Somerset although we often work further afield as well.

At Offplan3d we produce a wide range of CGI image styles. Wether the purpose is sales or visual assements for planning, we can provide the right solution for you.

Clear and impressive CGI property renders

detailed planning submission 3d render

The image above shows views from inside the proposed new home looking out over the neighbouring property. This is useful to assure planners there will not be any ‘over looking’ issues. Architects plans alone can miss a lot of this important information.

The advantage of 3d renders for planning– Many people can find it difficult to visualise the actual buildings represented by architects plans and elevations.

Most Councillors who sit on committees and make recommendations are usually neither architects nor builders. They can find it difficult to really visualise what is being shown to them.

This is when 3d renders really can make a big impression. Our CGI images accurately show the proposed property. In addition they also convey that the applicant is serious about getting the project approved.


3d house render with roof removed

A variety of cut-away and roof-off CGI shots can help to explain your property layout to planning departments.

Cost effective 3d renders with good ROI

How much does it cost? Prices can vary from a £100 upto £10K depending on the project and the amount/ standard of work required. This covers any budget from kitchen extensions to new build houses to the new national planetarium.

We understand how to get the required results with effective planning application 3d renders. Outline or detailed planning consent are obviously different to final sales images.

If the purpose of the CGI images was to sell the completed property to a potential homeowner then adding ‘aspirational lifestyle set dressing’ would be desirable. However this would be an expensive distraction to a planning department. By cutting out the clutter we are able to cut costs by up to half on our competitors.

Often quoted prices are given per image but the actual work is 85% 3d model creation. Once this is complete we offer additional images at low prices.To see examples of our property CGI render prices click here.

Easy and accurate 3d visualisation for planning

Our clients– vary from architects and design firms, to design and build, architectural designers and planning consultants.

Daylight studies- Using the location, date and time of day our software can show exact sunlight and shadows for your property.

Amendments– the planning department will often reject an application and make recommendations at the early stages of outline planning. Our existing 3d house model can be changed and new 3d renders produced. The additional cost of the changes will depend on the amount of work required.

Flexibility– whether you require interior 3d renders or exterior 3d renders we can produce professional results on time and budget. Cutaway  cross sectional images are another potentially useful option. We also offer online interactive 3d model viewers and immersive ‘magic window’ viewers on mobile devices.

Click the images below to enlarge. This project in Sidmouth was completed in about a week for around £1,400 in 2018

Sidmouth new home CGI

Luxury new build CGI Cornwall

luxury new build CGI marketing service image

The architectural design company asked our 3d visualisation studio to originate this luxury new build CGI and drone project in Cornwall. The proposed development site was a former hotel only a hundred meters from the beach in Marazion.

CGI visual impact assessment image service

The first part of this project was to create CGI visualization images to assist the detailed planning application. Due to the sites’ location in an Area of Outstanding Natural Beauty accurate visual impact photomontage images were required. This involved the production of a basic 3d CAD model of the proposed building development which was incorporated into the, client supplied, site photographs.

CGI images and video for estate agent marketing

The second part of the project was to produce final marketing CGI images and video.

In addition a drone video of the location was required onto which the CGI model of the new homes was to be added. This real world/CGI video compositing required testing due to technical difficulties with of the location, from the computing point of view. The issue was the lack of visual vertial reference points e.g tall buildings which would mean an inaccurate 3d solve (with CGI objects not moving exactly with the video). The alternative would be prohibitively expensive broadcast filming equiment.

Aerial filming and CGI integration service

Our visualisation studio used 3d mapping technology to plan our proposed drone service flight paths. The image below shows the legal limits for UAV flight radius and altitude around the development site.

Cornwall drone pre planning image

The proposed development buildings and site location 3d models were combined for pre-visualisation. The video below shows roughly how the final sales video of the live action drone video and CGI buildings might look.

The final CGI video would require around 250 hours of cloud  processing computer time per minute of finished video or 1,500 images. This is why pre-planning is so important.

New homes CGI service

South Devon new homes development CGI

New homes sold off-plan

Our Devon new homes CGI service built these 3d house models and generated the architectural renderings shown here. The property marketing images were commisioned by a south Devon estate agency.

Uneven site contour levels were ignored to keep the 3d modelling costs down. As only individual property images were used the client decided this wasn’t really an issue. The ‘for illustration purposes only’ caption was attached to the final estate agent marketing images.

The new homes were all reserved ‘off plan’ before our drone service was able to film the site and it’s surroundings. The issue being filming in winter with no leaves on the trees.

New homes CGI pricing

The 4 different high resolution property images were produced for budget price of circa £1,200.

Higher quality work is available but takes longer and therfore costs more.

Changing building materials

New housing developments often run into building supply issues. The projects’ schedule of finishes changed, at the last minute, from 15mm dark grey concrete roof tiles to light grey slates.

Luckily we were able to alter the roof tile colour and not rebuild all the roofs with the thinner slates. No additional charges were made for the extra work.

Marketing a listed building using our CGI and drone service

Adding CGI to an existing listed building​

CGI and listed buildings may initially seem to have little in common. However we will show you here how well they can work together for property marketing.

This CGI, drone and photography service was for an 18th century Manor house near Ottery Saint Mary in South Devon. The main house had been derelict for several years with staircases and floors missing.

Our job was to provide the estate agents with print and online marketing images before building works had finished.

We visited the site and photographed the exterior, interior and took aerial  video and images with our drone.

Back in our office we recreated the camera and building site in 3d space on our computers. We then used the architects plans to build the unfinished parts of the building and added these CGI elements to the original photograph. Various parts of the building and grounds were also ‘photoshopped’ to tidy them up. The final estate agent images were A4 at print resolution.

Interior photographs with CGI added

Initially the plan had been to produce fully set dressed CGI interior images. However this was later changed to taking on site photographs and adding the final flooring and removal of building debris and dirt.

A lot of the rooms were actually pretty small and difficult to photograph. To solve this problem we had to take several photographs and then photoshop them together. This gave a good impression of the rooms without too much ‘fish-eye’ distortion.

Phase two of the manor house CGI project

Around 12 additional houses are proposed for phase two of this project. They are to be built in the grounds of the manor house and we hope to be able to add the images here…

Residential Housing CGI Devon

residential house CGI external rendering Devon

The purpose of this residential housing CGI project in Devon was to produce estate agent marketing images.

The supplied architects plans and elevations were used to build the basic 3d house model. For added realism CGI surface materials were then added to the 3d model.

Next the basic house model was ‘set dressed’ by adding details such as curtains, plants, people and cars. Finally CGI lighting and skies were added along with cameras to take the images below.

Although the majority of our property marketing CGI work tends too be in South Devon we are based in North Devon.

The interactive 3d model to the right was added by ourselves as a quick test.

Although obviously unfinished it is useful to showcase what is possible in online property marketing.

A finished example of a 3d model that we fully optimise for speed and realistic lighting can be seen here.

South Devon CGI renderings

south devon CGI drone images

Our brief for this South Devon CGI rendering project was to produce 8 high resolution images. These images from the two new build homes were to be used for estate agent publicity literature.

The 360 degree images or photosheres shown below where an added bonus for the client. They work well for tight internal spaces, such as bathrooms. They solve the problem of a single image not capturing the whole room.

For really immersive VR experience we recommend viewing via Facebook on a smart phone or tablet. This allows the user to simply aim the device where they want to look.

Drone footage was supplied to us for adding the CGI house models. Unfortunately the drone video was not only expensive but also unusable which is the main reason we now use our own in-house drone equipment.

There is quite a lot of knowledge required to producing good drone footage for CGI. Just buying expensive equipment and software isn’t going to work.

We actually understand how the software works, it’s requirements and limitations. If in doubt please ask our advice.

An interactive WebGL model viewer is shown below. This allows the user to fully interact with the 3d model of the bungalow.

This was an unfinished test (from 2015) with lighting but no materials added. The technology has moved on quite a bit in the meantime so please ask us about the latest developments in VR and online 3D viewers.
