Commercial Architecture



Commercial Design Projects...

Mark English Architecture can accomodate small scale projects of up to a value of £1million with the support of established key partners to underpin quality and effective delivery in both the design and construction monitoring and support process.

Commercial projects are generally divided into classes for fee calculation purposes as follows:

  • Class 1: Agricultural buildings, sheds, stables.
  • Class 2: Community halls; dormitory hostels; warehouses; workshops.
  • Class 3: Factories; automotive sales showrooms; shops; offices.
  • Class 4: Food processing units; school buildings; health centres; churches; medical surgeries.
  • Class 5: Houses and flats for individual clients and developers.

  • Commerical Architectural Fees - New Works:

    Total construction
    5 4 3 2 1
    upto £ 100k 9% 8% 7% 7% 6%
    £ 100k to £ 250k 8% 7% 6% 6% 5%
    £ 250k to £ 500k 6% 5% 4% 4% 3%
    £ 500k to £ 1 M 5% 4% 3% 3% 2%

Fees may be based on a percentage of the total construction cost or on time expended, or may be a lump sum. Percentage fees are based on the total construction cost of the works; on the issue of the final certificate fees should be recalculated on the actual total construction cost. Where the client is the builder or supplies any material or labour, percentage fees should be based on an estimate of the total construction cost of the works as if they had been carried out by a builder supplying all labour and materials on a contractual basis.

  • Fees and expenses should be paid in instalments either at regular intervals or on completion of work stages in accordance with the RIBA Plan of Work 2013 as follows:

    Work Stage

    of fee
    Stages 2 & 3 35% 35%
    Stage 4 40% 75%
    Stages 5 & 6 25% 100%

Interim payment should be based on the current estimated cost of the work. The apportionment of fees is a means of assessing interim payments and does not necessarily reflect the amount of work completed in any work stage. By agreement an adjustment in the apportionment may be made.

Mr & Mrs Blunt

I found Mark to be very approachable - he listened to what we thought and gave design suggestions. We wouldn't hesitate to use him again in any future developments or to recommend him to family and friends.
