Services / Our Approach

1 - Brief

Initial Meeting

RIBA work stages A-B

The design process begins with a meeting with a designer at your property. This initial design session lasts for either half a day or a full day, depending on your requirements. We will help to define your brief and advise on the best way forward for the project.

  • Brief development

    We will assist with development of the brief and discuss alternative approaches for your project. This stage includes advising on the need for other consultants, from structural engineers to home automation specialists. We will also assess any soil or structural investigations required.

  • Proposed sketches

    We will discuss a variety of design ideas with you, including material finishes, organisation of spaces, qualities of natural light and views. Following this we will produce a set of scaled, hand drawn sketch plans.

  • Assess required consents

    The statutory consents required for your building project will be considered.

  • Cost information

    Your budget will be discussed and agreed. We will provide outline construction cost information based on current prices per square metre for comparable projects in London.

  • Draft programme

    A programme will be produced alongside the payment schedule that describes the sequence and duration of each element of the design and construction works until completion on site.

2, 3 - Concept, Definition

Outline Design

RIBA work stages C-D

The design process is a collaborative one, and your designer will discuss each aspect of the proposal in detail with you as the design develops. We provide drawings, material samples and 3D rendered views that illustrate the qualities of the proposed spaces.

  • Appoint consultants

    We will suggest appropriate consultants from our list of approved firms in London. These may include a structural engineer, a party wall surveyor and an approved inspector. Larger and more complex projects may additionally require a planing consultant and a quantity surveyor.

  • Outline designs

    Proposals will be developed into a full set of planning drawings. We can produce realistic 3D visualisations alongside sketch drawings to enable you to clearly envisage ideas. We will work closely with you to decide final appearance of the scheme, including material finishes, for which we can provide samples and mood boards.

  • Obtain cost estimates

    At this stage a quantity surveyor may be appointed to produce a detailed cost estimate of the scheme prior to submitting a planning application. This will ensure that the project is on budget. The cost report provides a detailed ‘shopping list’ of all items in the project, allowing informed decisions to be made if savings are required on specific items.

  • Planning consents

    Pre-application advice may be sought from the local authority. Following this, an application will be prepared for planning consents. Plans, elevations and sections will be submitted alongside a design and access statement. For smaller projects there is usually an eight week determination period, in which time the planners will consult with neighbours and relevant bodies.

  • Other consents

    Various other consents may be required, depending on the scope of the project. These may include listed building consent, freeholder consent for leasehold properties or Highways approval.

4 - Design

Detailed Design

RIBA work stages E-H

At this stage we will progress the design from planning drawings to a fully developed proposal, with detailed drawings and schedules describing the works. These form part of a package that will enable prices to be provided for construction.

  • Detailed Designs

    Detailed drawings will be produced to finalise all elements of the design, indicating key junctions, structural design, services including electrical layouts, and floor, wall and roof constructions.

  • Building Regulations

    A building regulations package including detailed drawings and notes are submitted to an approved inspector who will certify compliance with the building regulations.

  • Party wall notices

    Your designer will liaise with a party wall surveyor to ensure that the appropriate party wall notices are issued in accordance with the work described on the detailed drawings.

  • Interior Design

    We are able to produce a complete interior design for all projects, including soft furnishings. We also offer landscape design, bespoke joinery and kitchen design if required.

  • Selecting Building Contract

    We will advise on the selection of an appropriate building contract for the works, and explain the process of entering into a building contract and the duties of the client, the designer and the contractor at each stage.

  • Prepare Tender Documents

    Tender documents will be prepared to supply to contractors for pricing. These will include a schedule of works, detailed demolition and construction drawings.

  • Invite Contractors to Tender

    Contractors will be invited to tender, allowing a period of 4 weeks for contractors to review the documents and return completed tender submissions with a lump sum price and a total contract duration in weeks. We will advise on the selection of a contractor.

5, 6 - Construction


RIBA work stages J-K

During construction works, your designer will visit the site to see that work is proceeding in accordance with the proposed designs, and following completion will make final inspections and advise on any rectification works required.

  • Appoint a contractor

    A pre-contract meeting will be arranged with the selected contractor to discuss the project in detail and to present the building contract for signatures.

  • Issue Construction Drawings

    A full set of construction drawings will be issued to the contractor and work will begin on site.

  • Contractor's queries

    We will deal with queries and issue formal Designer’s Instructions to the contractor.

  • Certify Work Completed

    At regular intervals we will visit site to inspect all work, to ensure that it is completed to the required standard. Once this is agreed, we will certify the work completed and the sums due to the contractor. A 5% sum is typically retained until the end of the project.

  • Extensions of Time & Claims

    Typically a building contract contains provisions for damages to be awarded to the client for over-runs on the part of the contractor. The contractor may however claim for extensions of time for valid reasons. We will assess these and award if appropriate.

  • Final Account and Certificate

    The designer’s practical completion certificate transfers possession of the building to the client. At this stage the rectification period will begin. This is typically a 6 month period in which the contractor is instructed to return to rectify any relevant issues. Once the final certificate is issued at the end of this period the remaining retention sum is paid to the contractor.
