1. Meeting Holland and Green and the Feasibility Study

The first step in the process is to complete your Developing Your Brief questionnaire. This will help us understand your desires and aspirations and provides some background info on your property.  Once we have received and reviewed this we’ll give you a call to chat through your thoughts and ideas.  At this stage we will give you an idea of what might, or might not, be possible from a design and planning perspective.  This initial chat is also a great opportunity to check we are a good ‘fit’ – Projects tend to take quite a while to complete so it is important we all get on!

The next step is either to meet at one of our offices at a pre-arranged time (so we can prepare for you) or arrange a Home Consultation.  We’ll do some background research and then explore your thoughts and ideas in a little more detail.

We’ll be able to advise on what is possible from a planning perspective as well as providing some initial design suggestions.  After the Office Meeting or Home Consultation we’ll either send you an outline proposal for taking your Project from the initial Concepts through to the completed build, giving details on the journey ahead, time-frames and an estimate of the likely fees and other costs  or we’ll suggest we begin with a Feasibility Study.  The Feasibility Study will allow us to give you some additional design inspiration and help you understand the full potential of the house together with the likely challenges we might face and importantly the likely cost of the actual final build.  This Feasibility Study forms part of the subsequent work required in the Concept and Planning Stages.

Many Clients have found the Feasibility Study provides just the right amount of information to enable them to make an informed decision about the scope of what they want to do balancing aspiration and budget at this very early stage without investing a significant amount of money.

2. The Concept Design Stage

With the Feasibility Study complete you will have;

  • Options for various Scopes of Work and Design Options.
  • The Planning status and possible challenges we may face.
  • Interior and Exterior design precidents.
  • Early Costings for the potential scope of works options
  • The likely Programme / Timetable for the Project
  • An understanding of Next Steps and Fees for the entire project.




It’s time to Commission Holland and Green and the first thing we now do is to conduct a full digital 3D survey of your home and undertake the ‘Project Design Meeting’ to flesh out the initial Feasibility Brief and settle on the Project Scope.  At this point we’ll also set up your private Client Web Page on our website (we’ll be putting everything to do with your project on here) and (if not already complete) help you set up your own H&G Pinterest Board where we can inspire, collaborate and share ideas.

We will now build your home as a comprehensive and detailed 3D Model and begin to develop your 3D Concept Designs for you to review and digest.  When ready we’ll arrange for you to come to one of our offices for the Design Review Meeting where we will explore the scope of works in detail and start to refine the various Concepts into a single design that we will then progress with more detail and information.  This is often a good point to involve the Quantity Surveyor again to help understand a more accurate final cost of the design. Then, with the detailed design completed and signed off, we can proceed to the Planning Stage.

3.Planning Stage

It’s time to convert the final 3D model into more traditional 2D Plans to submit to the Council Planning Department for your Planning Permission or Permitted Development Certificate of Lawful Development Application.  We will manage the application through the process and keep you updated on progress.  We can also now start refining interior design and kitchen design and make sure we have covered other important elements such as party wall notices.

4.The Detailed Design Stage.

Once Planning Approval has been received (or before) we can begin to compile the Building Regulations drawings and commission the required Structural Calculations and get on with the Detailed Design.  Unlike the Planning drawings which demonstrate how the proposed alterations might change the look of the property and impact on its surroundings, the Building Regulations and Detailed Design Package is focused on, among other things, how the building work will be undertaken, thermal efficiency, suitability of products used and the structural integrity of the design. The final design might also require us to provide a SAP Report, or a Build Over Agreement with Thames Water.  The Building Regulations Package ultimately contains all the detail needed to gain Building Control Approval – without which the design cannot be built.

5.Specification of Works.

While Building Control is concerned with the ‘Nuts and Bolts’ of the build such as the materials used and the construction process,  the Specification of Works Stage allows us to work with you to create a room by room breakdown of the finishes that we can use to produce a detailed ‘Room Schedule’ detailing floor finishes, decoration, electrical fittings and so forth which can then be included with the Planning and Building Regulations Packages to create the full ‘Quotations Package’ ready to send out to builders to quote.  This is also often a good time to include an Interior Designer to finesse the fine detail and if you want us to undertake the Interior Design we’d be delighted.

6.The Build Tender Stage.

Holland and Green will be able to help you when it comes to Choosing Builders to generate Quotations for the work.  Or you can supply some, or all, of them yourselves from personal experience or recommendation.  We endeavour to ensure that all builders are quoting on a ‘like for like’ basis so that we can compare and negotiate from the quotes that are subsequently received.  Once you have selected your preferred Builder and you have checked references and are confident to move forward, we will be able to prepare and arrange the signing of the Contract.  It is worth noting that good builders are usually busy builders so you might need to wait for the right team.

7.Build Stage Contract Administration

In order to be confident that what was designed and specified will be built, you will require the input of an expert to ensure that (a) Time-frames are adhered to (b) Costs are tracked and controlled (c) The quality of finish is maintained and (d) ultimately to ensure everything runs smoothly and that relations between Client and Builder remain good.  We are also keen to ensure that our design is completed to a high standard and to ‘hold your hand’ through this final and crucial stage.  This is achieved with our Contracts Administration Service which puts a H&G professional, or one of our associates, supporting you throughout the build.


This is the bit we have all been working towards over the past year or more.   Completion Certificates, operating manuals and all the elements that conclude the Build are handed over. We are as excited by each new Project as our Clients and look forward to catching up with you in your new ‘Wonderful Living Space’ and hope that you will now start telling your family and friends about us!
