Design & Build

London's Leading Design and Build Contract Company

Design and build is the evolution to the traditional method of hiring separate architects and builders and it’s why Bischell utilises this approach for many residential and commercial projects.

By providing every service under one roof, Bischell can handle your entire project from start to finish. This includes architectural planning, designing, building regulations and planning permission, structural engineering, constructing and managing your project to achieve a perfect result which fits exactly what you’re looking for.

Our Approach

How it all works in 7 simple steps

Click the white arrows below to view the step-by-step approach we’ll take through the design, planning, build and construction of your project.


Capturing your vision

We’ll discover exactly what you want when it comes to themes, colours, features, layouts and functionality. Bring all of your ideas to the table and we’ll make sure they’re taken on board.

At this stage, we also conduct feasibility studies to ensure that your property, your budget and any relevant planning laws can fulfil your requirements, so you know sooner rather than later.


Bringing your ideas to life

Our creative designers will begin producing concept designs and sketches. This is a collaborative process where we work closely with you to develop ideas into a final set of plans for the build phase. You can also hand-pick materials, fixtures and fittings with guidance from our experts.

During this stage we invite all of your thoughts and feedback, making as many revisions as required until you’re delighted with the final plans.


See how it looks in 3D

We’ll take the designs and create realistic 3D renders which show exactly what the new environment will look like. 3D walkthroughs also allow you to look around inside the space from every angle before the first brick is even laid.

See something you would like to change? Nothing is set in stone at this stage, so we’re happy to work on further changes until you’re 100% happy.


Hassle-free planning permission

We’ll create detailed plans and submit the paperwork to your local council authority for planning permission approval.

With hundreds of successful applications and a 97% first-time success rate, we understand the process inside-out. We’ll liaise with the authority on your behalf to obtain full approval, and if they ask for any revisions, we can handle those for you as well.


Hassle-free building control approval

We can assess if your project requires building control approval from your local council. If necessary, we’ll submit the paperwork and all relevant plans, including engineer’s reports and structural calculations, to ensure the fastest possible process.


Preparing for the build

You’ll receive a guaranteed, fixed-price quote which is fully itemised down to the last penny. We’ll also prepare a detailed construction programme and begin organising every aspect of the build, including on-site teams, tradespeople, equipment and materials. Meanwhile, your dedicated project manager will be on hand to guide you through the process.


Construction and sign-off

You can now relax and look forward to the final result as the build teams begin construction under the orchestration of your project manager. The detailed program will ensure that the right people, tools and materials will be on-site at the right times for a seamless build with meticulous attention to detail throughout.

Then, only when you’re delighted with every aspect, you can sign it off and enjoy. All delivered on-time, on-budget and defect-free.

    Dave Jones West Finchley – Barnet

  • They deliver flawless work for sure, but the service delivery model they have here is stand out. There's few companies I work with day-to-day that match it. As they grow it'll be interesting to see whether standards can be maintained...
