House extension quotes in Cyprus — what should be in writing

An extension quote that can be compared against another one states the consent position and who carries it, the new floor area and how it was measured, the foundation design, the structural work where the addition meets the standing house, the roof abutment and its waterproofing, the services extended, the envelope specification, the making-good, the programme, the payment stages and the variation rates. Anything shorter is a total resting on assumptions, and on a Cypriot extension those assumptions are structural or statutory rather than decorative.

Recorded ranges are held per square metre of new floor area, shell to habitable finish, with the sample size and the month noted against each figure — a unit that only becomes useful once the items below are written down.

Why written scope matters

The new room is the least variable part of an extension. Blockwork, a slab, a door and a window behave much the same in Aradippou as in Chloraka. What varies is the joint — foundations beside existing foundations, the opening cut through a load-bearing wall, the roof meeting an old parapet without leaking, new render against weathered render. None of that shows in a price per square metre, which is why two quotes for one drawing can be far apart and both be honest.

Statutory scope is the second half of the problem. Adding floor area requires planning permission and then a separate building permit, and how much may be added is capped by the plot's building coefficient and coverage ratio rather than by what fits on the garden. The consent stage runs in months rather than weeks and precedes any construction, so a quote that begins at "start on site" has handed a multi-month statutory process to the owner without saying so.

The building stock makes the omissions predictable. Around Aradippou, where newer detached housing dominates and extensions outnumber structural renovation, the usual case is a clear plot and an unremarkable interface. In the 1970s to 1990s stock filling Strovolos, the frame was designed to earlier codes and an appraisal comes before a price. In parts of Pissouri, known ground movement makes a structural survey standard. Recorded quotes sit above the island median in Limassol and below it in Famagusta district — availability rather than blockwork, and written scope is what tells the two apart.

The eleven items a quote needs

1. 1. The consent position, in writing, with dates

   Whether planning permission and the building permit are applied for, who prepares and submits the drawings, whose name the fee sits in, and what the programme assumes about the wait. The Department of Town Planning and Housing runs both stages, and they are sequential.

2. 2. New floor area and how it was measured

   Internal or external measure, and whether a covered veranda, a light well or a stair enclosure counts towards it. The building coefficient and coverage ratio decide the ceiling, so the measurement basis determines whether the design is permissible at all.

3. 3. Ground investigation and foundation design

   What the foundations are, what they bear on, and who established that. A single-storey ground-floor addition of roughly 20 to 30 m² is the common domestic case and often needs little more than trial pits. On sloping plots and where movement is known, as in parts of Pissouri, the survey precedes the design and belongs in the quote as its own line.

4. 4. The structural interface with the existing building

   Named registered engineer, and what the appraisal concluded. Column jacketing, foundation enlargement and slab strengthening separate a first-floor addition from a ground-floor one, and they are settled by calculation rather than by inspection from the street.

5. 5. The opening formed through the existing wall

   Width, lintel or beam, temporary propping, and who makes good the reveals and floor finish either side. A small item that produces large arguments, being the one place where the extension damages the house still being lived in.

6. 6. Roof form and the abutment detail

   Flat reinforced-concrete slab or pitched, the falls, the outlets, and how the new roof meets the existing wall or parapet. Abutments are where extension roofs fail, and a quote listing waterproofing without describing the upstand and flashing has priced a material rather than a detail.

7. 7. Envelope specification, including the junction

   Insulation type and thickness, glazing, and shading. The thermal bridge where old meets new is routinely omitted. Inland, Nicosia carries the widest temperature range on the island, so both do more work there than on the coast.

8. 8. Services extended into the new space

   Circuits, sockets, lighting, water, drainage falls and connection point, and provision for cooling. Whether the existing consumer unit has capacity is a yes or no question, and in older stock the answer is often no.

9. 9. Access, site set-up and spoil removal

   Where materials are stored, how concrete arrives, what size vehicle reaches the plot, and who pays for skips and spoil. On the hillside plots above Peyia, steep access roads limit crane and delivery vehicle size. Around Polis Chrysochous, distance from the Paphos contractor base adds travel time to quoted day rates, and it should be shown rather than buried in the rate.

10. 10. Making good and the external finish

    Whether the render is matched to the existing elevation or the whole elevation refinished. New render beside weathered render stays visible for years, and the gap between patching and refinishing surfaces at handover.

11. 11. Programme, with its assumptions named

    Start date, duration, and whether the consent period sits inside or outside it. In Famagusta district the seasonal accommodation around Ayia Napa concentrates refurbishment into November to March, so winter capacity there is committed well in advance.

Payment stages

Payments should attach to completed and inspectable events, never to calendar dates, because dates arrive whether or not anything was built.

A workable structure ties a modest mobilisation payment to the permit being in hand and the site set up, then stages to foundations complete, structure and slab complete, roof watertight, first fix of services, plaster and screed, second fix, and practical completion. A retention held for a defects period after handover is normal on building work and is the only leverage that survives the final payment.

Design and consent fees are a separate schedule from construction. An engineer or architect is normally paid at drawing submission and at permit issue, months before a block is laid, and merging the two schedules hides what has been paid for what.

Variations and how they are priced

A variation is any work outside the written scope. The rates are negotiable before the first variation exists and not afterwards, so the quote should carry a labour day rate, the markup on materials bought for a variation, and a threshold below which small items are absorbed. Four are common enough on Cypriot extensions to be priced now as provisional sums:

• Ground conditions different from assumed. Fill, rock, or a bearing stratum deeper than the trial pits suggested. Priced per cubic metre of excavation and of additional concrete.
• Existing structure needing strengthening. Most likely where the addition loads an older frame. The engineer's appraisal turns this from a discovery into a priced option before signature.
• Original permit drawings that cannot be found. Common on older properties. The first cost is a surveyor and a Land Registry search rather than a builder, and it sits on the critical path.
• Drainage connection further than surveyed. Priced per metre of run, plus reinstatement of whatever surface it crosses.

Red flags

• A price per square metre with no drawing behind it. Without a plan and a structural position it is a market average with a project name above it.
• Consent treated as optional. "It can be regularised later" means build first and apply afterwards, and that cost falls on the owner.
• No named engineer on anything structural. ETEK maintains the register of qualified professionals, and registration is easier to check before signature.
• The roof abutment absent from the scope. The clearest sign the quote was written from a floor plan rather than from a site visit.
• Payments tied to dates rather than to stages. Nothing about a date is inspectable.
• One total with no split between shell and finish. They move independently.

The extension price guide on this site holds the current ranges with their sample sizes attached, the district area pages break the same figures down by location, and the contractor listings record extension contractors across five districts with the towns each one actually covers.

Common questions

Does a house extension in Cyprus need planning permission?

Yes. Adding floor area requires planning permission and then a separate building permit, both handled through the Department of Town Planning and Housing and the relevant local authority. How much area may be added is limited by the plot's building coefficient and coverage ratio.

How long does the consent stage take?

Months rather than weeks, and it precedes construction rather than running alongside it. A quote's stated duration means very little unless it says whether the consent period sits inside or outside that figure.

Is a first-floor addition more expensive than a ground-floor one?

Generally, and the reason sits below ground rather than above it. The existing frame and foundations have to be assessed for the load they are about to receive, and jacketing columns or enlarging foundations produces no visible floor area.

How many quotes should be requested?

Three, and only if all three price the same written scope — same drawing, measured area, foundation basis, roof detail and finish standard. Otherwise the lowest figure belongs to whoever assumed the least.

When is the best time of year to start?

Autumn and winter suit the groundworks and structural phases in most of the Republic, since concrete work is easier out of high summer heat. In Famagusta district the calendar runs the other way, because seasonal accommodation concentrates refurbishment between November and March.
